Boeing 737 MAX production cap lifted as FAA clears output ramp

Boeing 737 MAX

Boeing 737 MAX production cap has been lifted by the FAA, unlocking the next output phase. The regulator now allows build rates to rise to 42 aircraft a month, after a year of constrained output and intense scrutiny. As a result, Boeing regains limited flexibility to align 737 MAX production with its delivery guidance and record backlog.

However, the Boeing 737 MAX production cap was not removed lightly. The FAA first imposed a 38-per-month ceiling in January 2024, following a midair panel blowout and temporary groundings. Inspectors then conducted extensive reviews of Renton’s production lines to verify that even a “small” output increase could be achieved safely. The regulator will retain direct oversight of quality control processes, signalling that safety remains the primary constraint on further rate hikes.

Gradual rate increases to support delivery guidance

Boeing is planning a measured ramp rather than a sudden surge in output. The company has stated that any increase beyond the new Boeing 737 MAX production cap will occur in increments of five aircraft per month. Moreover, management has indicated that each step-up will come no earlier than six months apart, reinforcing a cautious “stair-step” approach.

Meanwhile, the airframer is relying on three Renton assembly lines and elevated inventory levels to hit its 2025 delivery targets. Boeing needs to ship only 70 additional 737 MAX aircraft in the fourth quarter to meet its guidance of about 400 units. That target now looks more achievable with the higher monthly ceiling, especially as the company works through disruptions from earlier supplier issues and last year’s labor strike.

What the lifted cap means for the wider supply chain

The lifting of the Boeing 737 MAX production cap will ripple across the aerospace supply chain. Spirit Aerosystems and other structural suppliers can now plan for a modestly higher and more predictable intake of shipsets, after months of throttled flows. As build rates climb, demand should gradually strengthen for advanced alloys, fasteners and systems tied to the 737 programme.

However, suppliers should not expect an immediate return to pre-crisis volumes. Boeing still faces regulatory oversight, reputational repair and the need to embed new quality disciplines before considering faster ramps. Therefore, the initial increase to 42 aircraft a month is best seen as a stabilisation step, rather than a full-scale growth phase. For metals and component suppliers, the near-term focus remains on reliability and schedule performance over volume growth.

The Metalnomist Commentary

The FAA’s decision confirms that Boeing has done just enough to justify a controlled production increase, but not enough to regain full autonomy. For the supply chain, the change offers welcome visibility without removing the discipline imposed by recent crises. The key question now is whether Boeing can sustain quality improvements while gradually rebuilding 737 MAX output over the next planning cycle.

Boeing’s Commercial Deliveries Climb in Q1 Despite Challenges

Boeing

737 MAX Drives Boeing’s Rebound in Aircraft Deliveries

Boeing significantly increased commercial aircraft deliveries in the first quarter of 2025, marking a 57% year-on-year rise. The aerospace giant delivered 130 units, up from 83 in Q1 2024, led by its flagship narrowbody jet, the 737 MAX. The company shipped 105 of these aircraft, showing strong sequential growth from 36 units in the previous quarter.

This performance follows a turbulent 2024, when a seven-week labor strike halted production. Additionally, a mid-air panel blowout in January led to increased FAA oversight and a production cap of 38 units per month. However, Boeing resumed operations in December and appears on track to meet its internal production targets.

FAA Cap Remains, but Boeing Eyes Higher Rates

The FAA has maintained its limit of 38 aircraft per month, imposed after safety concerns earlier this year. Despite this, Boeing anticipates reaching this cap soon and targets 42 units per month by year-end, assuming regulatory approval. While deliveries don’t mirror production precisely, they remain a key performance metric for the firm.

Meanwhile, the 787 Dreamliner program remained flat at 13 units in Q1, slightly down from 15 units in the prior quarter. Supply chain stakeholders remain cautious and have not yet ramped up operations to match Boeing’s projected output.

Tariff Uncertainty Clouds Industry Outlook

The US government’s new tariffs on 4 April have added uncertainty for aerospace suppliers. While raw materials like titanium are exempt, there is concern over possible duties on components and subassemblies. Original equipment manufacturers are assessing how these policies could impact costs and sourcing strategies.

Boeing's ability to meet its aggressive 2025 production goals will depend on labor stability, regulatory coordination, and the response of its global supplier network. With geopolitical and regulatory variables in play, steady execution will be key in regaining customer confidence.

The Metalnomist Commentary

Boeing’s Q1 surge in 737 MAX deliveries is a welcome sign for a company seeking operational redemption. Yet with FAA limits, trade policy shifts, and cautious suppliers, the path forward requires more than numbers — it demands resilience, coordination, and trust.

FAA Issues New Regulations for Certain Pratt & Whitney Engines

The Federal Aviation Administration (FAA) has implemented a new airworthiness directive for specific Pratt & Whitney engine models. This measure follows a 2020 incident where an engine experienced an in-flight failure, resulting in a turbine blade detachment and a titanium fire within the high-pressure compressor (HPC).

Effective August 13, the directive covers PW2037, PW2037M, and PW2040 engines equipped with certain high-pressure turbine (HPT) second-stage blade assemblies. These engines power Boeing's 757 commercial aircraft, whose production ended in late 2003, and the C-17 military transports, as stated by Pratt & Whitney.

The FAA estimates this directive will affect around 425 engines on US-registered planes, requiring 24 work hours and costing operators a total of $867,000 for compliance. Should replacement parts be necessary, additional costs could reach $473,000.

The directive stems from a September 2020 incident where a PW2037 engine on a 757 shut down mid-flight. Pratt & Whitney's investigation revealed fractures in two lugs on the turbine hub assembly, leading to the detachment of four turbine blades, further damaging the HPC and causing a titanium fire.

This incident revealed that some blade assemblies did not meet conformance standards, posing potential stress failure risks that could endanger engines and aircraft. The FAA responded with a Notice of Proposed Rulemaking (NPRM) on August 25, 2023.

Meanwhile, Pratt & Whitney is also dealing with another issue involving its PW1100G-JM engine model. A powdered metal additive used in some HPT and HPC discs was found to contain contaminants in certain cases.

As a result, the company has accelerated inspections of the geared turbofan engines powering Airbus's A320neo aircraft. Engine shop visits for the PW1100G-JM increased by 50% year-over-year in April. RTX, Pratt & Whitney's parent company, expects an average of 350 aircraft to be grounded annually from 2024 to 2026 to carry out these inspections and any necessary rework.

Boeing Grounds 777-9 Test Fleet Due to Titanium Part Issue

Boeing has temporarily grounded its 777-9 test fleet after discovering that a titanium structural component failed to perform as expected during a routine maintenance check. The aerospace giant, based in Virginia, revealed that the part, which serves as a mount between the plane's engine and wing pylons, will be replaced before flight testing resumes. However, the company has not disclosed specific details regarding the nature or extent of the flaw.

The component in question is unique to the 777-9, the larger commercial variant of Boeing's twin-aisle 777X program. The aircraft is powered by GE Aerospace's advanced GE9X engines, and Boeing emphasized that each engine has two of these parts to ensure redundancy in case of failure.

The incident raises questions about whether this defect could further delay the 777-9's certification process with the Federal Aviation Administration (FAA). The FAA began test flights in mid-July, following years of setbacks to obtain type inspection authorization. Boeing assured that the FAA is being kept fully informed and that its customers have been alerted to the issue.

In a related development, the FAA issued an airworthiness directive this week affecting nearly 900 Boeing 787 Dreamliners worldwide. The directive requires inspections and potential fixes for switch caps on cockpit seats that could cause unintended and sustained movement, posing a risk to auto-pilot and other flight control functions. This action follows a March incident where a LATAM Airlines flight experienced a severe shake midflight, leading to a dive and passenger injuries.

FAA Approves Pratt & Whitney’s New GTF Advantage Engine for Airbus A320neo

Pratt & Whitney

Engine Upgrade Extends Life Cycle and Boosts Long-Range Capabilities

The U.S. Federal Aviation Administration (FAA) has approved the GTF Advantage engine by Pratt & Whitney for commercial use. This next-generation engine will power Airbus A320neo aircraft starting in the second half of 2025.

The GTF Advantage is an upgraded version of the PW1100G-JM geared turbofan (GTF) engine. It will become the production standard for Pratt & Whitney-powered A320neo aircraft, the company confirmed last Friday.

Airbus also offers the LEAP-1A engine, made by CFM International, a joint venture between GE Aerospace and Safran. Together, these two engine options define the propulsion strategy for Airbus’ best-selling narrow-body jet.

Engineering Enhancements Aim to Extend Time on Wing

The GTF Advantage was designed to extend time on wing and reduce engine maintenance cycles. To do so, Pratt & Whitney integrated a new airfoil design and advanced coating technologies in the high-pressure turbine.

Operating temperatures have been lowered through component upgrades, improving fuel efficiency and durability. Some of these enhancements can already be applied to existing GTF engines to deliver immediate performance benefits.

The engine also provides greater takeoff thrust, allowing it to serve larger variants like the A321XLR. This extra-long-range model aims to compete with widebody jets on transcontinental and long-haul routes.

Airbus and Pratt & Whitney Push the Narrow-Body Frontier

Airbus has received over 500 orders for the A321XLR, signaling strong demand for fuel-efficient long-range narrow-body aircraft. Airbus recently delivered its first LEAP-powered XLR aircraft to Iberia, a major Spanish airline.

Pratt & Whitney, a subsidiary of RTX, continues to innovate in high-performance propulsion for commercial aviation. With FAA certification now secured, the GTF Advantage sets a new benchmark for engine longevity, sustainability, and flight efficiency.

FAA and EASA Certify CFM LEAP-1A HPT Blade for Durability Enhancement

CFM International

The FAA and EASA have certified CFM International’s upgraded high-pressure turbine (HPT) blade for the LEAP-1A engine, improving durability and extending time on wing in hot environments.

Durability Boost for LEAP-1A Engines

The Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA) have approved a critical hardware upgrade for the LEAP-1A engine developed by CFM International, a joint venture between Safran Aircraft Engines and GE Aerospace. The newly certified high-pressure turbine (HPT) blade kit aims to increase engine durability, particularly in extreme operating environments like the Middle East, and enhance the engine's time on wing.

The certified kit includes:

• HPT stage-one blade
• Stage-one nozzle
• Forward inner nozzle support

These components are designed to withstand high operating temperatures, improving the engine’s overall performance and lifecycle.

Addressing Supply Chain Bottlenecks

The LEAP-1A engine powers Airbus A320neo aircraft, while the LEAP-1B variant exclusively powers Boeing’s 737 MAX. However, the supply chain for HPT blades has faced significant challenges, impacting engine deliveries in the first three quarters of 2024. During its third-quarter earnings call, Safran revealed that while certification of the new HPT blade was imminent, the delays had already constrained production.

With the certification complete, CFM International is prepared to ship the upgraded blades, focusing first on the maintenance, repair, and overhaul (MRO) market. This should alleviate pressure on airlines operating LEAP-1A engines, many of which are critical to global aviation fleets.

Certification for an updated HPT blade for the LEAP-1B variant is expected by the end of 2025, signaling further advancements in turbine blade technology for Boeing aircraft.

Advanced Materials for Extreme Performance

The high-pressure turbine blades are made from nickel-based superalloys that include chromium, molybdenum, and cobalt, which allow them to endure extreme temperatures and mechanical stress. These advanced materials are vital to enhancing the performance of modern aircraft engines, particularly in demanding conditions.

The certification underscores CFM International’s commitment to advancing engine technology and meeting the evolving needs of global aviation.

Boeing Targets 737 MAX Output Cap Lift in 2025

Boeing 737 Max

Boeing anticipates US approval to raise 737 MAX production beyond the current cap in 2025. This aims to recover from 2024's challenges.

FAA Approval Hinges on Quality Improvements

The FAA capped 737 MAX production at 38 aircraft per month. This followed quality control concerns. Boeing now anticipates exceeding this limit later in 2025. This relies on demonstrating stable production at 38/month. CEO Kelly Ortberg notes "significant improvement" in quality control. Moreover, Boeing has an "agreed-upon path" with the FAA. Sufficient parts inventory also supports build rate increases.

Production Recovery and Future Targets

Production resumed in December after a seven-week strike. Currently, Boeing produces 737 MAX aircraft in the low-to-mid 20s per month. This month, 33 jets have been delivered. All three Renton assembly lines are operational. A fourth Everett line provides flexibility for future increases. Boeing targets 42/month by year-end. 2025 deliveries might resemble 2023, with an average of 33/month. 787 Dreamliner production aims for 7/month.

Boeing Refutes Report on 737 MAX Output Decline

Boeing 737 Max

Boeing Clarifies 737 MAX Production Stability

Boeing has firmly denied claims of a production slowdown for its 737 MAX aircraft at the Renton, Washington facility. The company stated it has not reached a 38-unit monthly production rate in 2024 and has not reduced output. This statement follows a report from The Air Current suggesting a drop in wing assembly output from February to March.

Recovery Efforts Continue Post-Strike

Boeing resumed operations in December after a seven-week worker strike halted manufacturing at its key 737 facility. Since then, the company has methodically increased output and aims to stabilize the 737 MAX production line. It targets a build rate of 38 aircraft per month in 2025, which aligns with the current FAA-imposed production limit.

Supply Chain Watching Closely Amid FAA Oversight

Boeing aims to exit 2025 at a monthly rate of 42, pending FAA approval to lift current restrictions. Suppliers are closely tracking the ramp-up, as Boeing’s 2024 quality control issues have already disrupted expectations. Maintaining momentum is vital to rebuild confidence in the narrowbody program and support global delivery timelines.

The Metalnomist Commentary

Boeing’s public pushback signals an effort to manage stakeholder expectations amid scrutiny from regulators and supply chain partners. With global demand for narrowbody aircraft recovering, the company’s ability to meet ramp-up targets will be crucial for reasserting leadership in the commercial aviation sector.

Carpenter 737 MAX demand set to jump after FAA cap increase

Carpenter Technology

Carpenter 737 MAX demand will rise as Boeing’s cap moves to 42 per month. Carpenter 737 MAX demand benefits from stronger aerospace bookings. Therefore, Carpenter 737 MAX demand should lift revenues and melt utilization.

Order momentum builds across aerospace and defense

Carpenter reports accelerating orders after the FAA’s decision. Bookings in aerospace and defense rose 23% quarter over quarter. The segment delivered $388.3mn, up 11% year over year. It represented 64% of total revenue in the quarter. Meanwhile, management signed five large long-term agreements. Profit reached $122.5mn, up 44% from last year. However, specialty alloys shipments fell 11% to 44.8mn lbs. Even so, brownfield melt expansions remain on budget for 2027.

The Metalnomist Commentary

Boeing’s 737 MAX cadence supports Carpenter’s long-cycle visibility. Yet mix shifts and medical softness could temper margin upside. Watch melt ramp timing, forgings bottlenecks, and contract pricing through 2027.

Boeing 737 MAX Build Rate Hits Target as 787 Ramps, Easing Titanium Gloom

Boeing 737 MAX

Boeing 737 MAX build rate hit its target in the second quarter. The Boeing 737 MAX build rate reached 38 jets per month. Boeing now seeks removal of the FAA cap as the Boeing 737 MAX build rate stabilizes.

Production recovery and path to higher rates

Boeing increased 737 MAX output to the FAA-limited 38 per month. The company aims for 42 per month later this year. Earlier, a 2024 panel blowout forced tighter quality control. Spirit Aerosystems shipset intake slowed to improve quality. A 2024 strike pushed 737 MAX output to zero before December restart. Consistent performance at “rate 38” will underpin any request.

Titanium demand brightens with widebody momentum

Boeing lifted 787 Dreamliner output to seven per month. That shift supports titanium supply chains hit by earlier slowdowns. Widebodies consume roughly double the titanium of narrowbodies. The 787 is about 15pc titanium by weight. The 737 MAX uses roughly 6–7pc, industry estimates suggest. Boeing also began building the 777-8 freighter. The freighter contains an even higher titanium share.

Deliveries, backlog, and financials improve

Quarterly deliveries rose 63pc to 150 aircraft. Sequential deliveries climbed 15pc. Boeing’s backlog exceeded 5,900 aircraft after 455 net orders. Quarterly revenue increased 35pc to $22.7bn. The quarterly loss narrowed to $612mn from $1.4bn.

Trade deals temper cost risk, but gaps remain

Zero-for-zero aerospace tariff deals eased cost pressure. Boeing now sees less than the earlier “$500mn bogey.” Agreements with the UK, EU, and Japan helped. However, no deal exists yet with Italy on certain fuselage parts. USMCA talks remain a watchpoint for cross-border components. A steadier Boeing 737 MAX build rate depends on predictable trade terms.

The Metalnomist Commentary

Boeing’s output stabilization materially lifts titanium demand signals, especially from widebodies. Watch the 777-8F ramp and FAA decisions for timing. Tariff carve-outs reduce risk, but Italy and USMCA outcomes still matter for margins.

Carpenter aerospace demand set to rise as 737 MAX cap increases

Carpenter Technology

Carpenter aerospace demand is poised to rise after the FAA lifted Boeing’s 737 MAX production cap. The higher build rate strengthens Carpenter aerospace demand across key jet engine and structural alloy grades. As a result, Carpenter aerospace demand should underpin a multi-year earnings and investment cycle for the specialty alloy producer.

737 MAX ramp unlocks stronger Carpenter aerospace demand

The FAA’s decision to raise the 737 MAX cap from 38 to 42 aircraft per month is a clear upside signal. Carpenter’s chief executive Tony Thene said the change is “a very significant positive” as customers move quickly to increase orders. Higher narrowbody build rates translate directly into more demand for nickel and titanium-rich alloys used in engines and critical structures.

Aerospace and defense already dominate the company’s revenue mix and will amplify Carpenter aerospace demand further. In the fiscal first quarter, aerospace and defense sales rose 11pc to $388.3mn and accounted for 64pc of total revenue. Bookings in the segment jumped 23pc quarter on quarter, supported by five large long-term agreements that lock in alloy volumes over several years.

Beyond aerospace, energy, industrial and consumer markets also contributed to growth, even as medical and transportation softened. Energy sales rose 8pc year on year to $42.5mn and industrial and consumer revenue increased 4pc to $75mn. These diversified end markets help stabilize earnings while Carpenter aerospace demand remains the main engine for margin expansion.

Melt capacity expansion supports multi-year aerospace growth

Carpenter plans to expand both primary and secondary melt capacity through brownfield projects. The company expects these investments to complete in 2027 and says work remains on budget and on schedule. Additional melting capacity will help relieve bottlenecks in high-value specialty alloys required by jet engine and defense customers.

Specialty alloys shipments fell 11pc year on year to 44.8mn lbs, highlighting current capacity tightness and product mix optimization. However, overall profit still surged 44pc to $122.5mn, showing the pricing power of aerospace-grade alloys. As new melt capacity comes online, Carpenter aerospace demand can convert more directly into volume growth rather than just price and mix gains.

Management continues to emphasize a “strong, multi-year outlook” for aerospace, defense, medical and power generation markets. The 737 MAX ramp, together with broader fleet renewal and engine upgrade programs, should keep Carpenter aerospace demand elevated well beyond this year. The company is positioning its footprint to support higher OEM build rates and long-term aftermarket needs.

The Metalnomist Commentary

Carpenter aerospace demand illustrates how incremental changes in OEM build caps can cascade through the alloy supply chain. The 737 MAX increase looks small in monthly units, but it drives multi-year demand for complex nickel and titanium-based products. For metals suppliers, the combination of locked-in contracts, melt expansion and tight aerospace specifications points to sustained pricing power, even if some industrial segments lag.

Boeing Set to Resume 777X Certification Flights Amidst Delays

Boeing

Reviving the Path to Commercial Approval for Boeing's Largest Wide-body Aircraft

Boeing is set to reinitiate certification flights for its 777X aircraft, marking a significant step forward in its efforts to bring the wide-body aircraft to market. This move comes five months after a critical pause due to a structural failure in a titanium component, which led to the grounding of its test fleet. The aerospace giant, headquartered in Virginia, has announced its collaboration with the Federal Aviation Administration (FAA) to restart these crucial tests.

Addressing Setbacks and Regulatory Challenges

The grounding of the test fleet in late August highlighted a design flaw during a maintenance review, prompting a temporary halt in the evaluation process. This incident adds to a series of delays for the 777-9, the larger variant of the 777X family. The FAA’s slow authorization process has already pushed back the timeline, with commercial approval still anticipated to take several additional months.

Implications for Future Deliveries and Boeing's Use of Titanium

Due to the testing pause and a consequential seven-week strike last fall, Boeing has revised the first delivery schedule of the 777X to 2026. Notably, the 777X stands as Boeing’s most titanium-intensive project to date, with the lightweight, high-strength metal constituting up to 20% of the aircraft by weight. This significant use of titanium not only underscores the aircraft's innovative design but also Boeing's commitment to enhancing performance and efficiency.

GKN Aerospace Expands Titanium Additive Manufacturing for Aircraft Engines

GKN Aerospace

Scaling Up Titanium Additive Fabricated Components

UK-based GKN Aerospace is scaling up production of its titanium additive fabricated fan case mount ring (FCMR), aiming for serial production by late 2025. The component is manufactured for Pratt & Whitney’s PW1000G geared turbofan engine, which powers the Airbus A220 and Embraer E195-E2. Rising global demand for narrowbody engines has accelerated the company’s timeline.

GKN currently produces about 30 units per month at its Trollhattan, Sweden facility and expects to reach 40 units monthly by year-end. This ramp-up demonstrates the company’s ability to align with engine manufacturers’ rising production requirements.

Sustainability and Regulatory Approvals Driving Growth

The company’s laser wire deposition additive process reduces material waste by around 40pc per part compared with forging or casting. In 2024, GKN saved 24t of titanium, cutting emissions by 395t of CO₂. These improvements highlight the importance of additive manufacturing in aerospace sustainability.

GKN also received FAA approval for its first additively fabricated structural component and produced its largest all-additive titanium engine case for the CFM RISE engine demonstrator. Regulatory acceptance marks a crucial milestone for the wider adoption of additive technologies in aerospace.

Investment and Future Expansion Plans

In January 2024, GKN invested £50mn ($67mn) to expand additive fabrication capacity. This investment supports its modular production concept, which enables rapid deployment across global sites. Full acceleration of expansion is expected from 2026 onward, reflecting long-term confidence in additive manufacturing.

The Metalnomist Commentary

GKN Aerospace’s titanium additive manufacturing push underscores the industry’s shift toward lighter, sustainable, and cost-efficient production methods. By integrating FAA-certified additive parts into commercial engine programs, GKN positions itself as a key supplier in the evolving aerospace value chain. Long term, additive manufacturing may reshape global titanium demand dynamics as aerospace producers prioritize efficiency and emissions reduction.

Boeing 777X delivery delay to 2027 ripples through aerospace metals supply chain

Boeing 777X

The Boeing 777X delivery delay to 2027 deepens uncertainty for airlines, suppliers and titanium scrap markets. Boeing pushed its first 777-9 handover back by a year, triggering a $4.9bn charge and another reset for the flagship widebody. As a result, the Boeing 777X delivery delay directly affects the aerospace titanium cycle, as the model is estimated to contain up to 20pc titanium by weight.

Certification setbacks reshape Boeing 777X delivery delay

The latest Boeing 777X delivery delay stems from slower-than-expected certification progress with the US Federal Aviation Administration. Boeing had expected type inspection authorisation in the third quarter but underestimated the scale of data and analysis the FAA required. Therefore, the company revised its production plans to limit pre-certification aircraft and align output with a more conservative, long-term schedule.

The $4.9bn charge mainly reflects penalties to airlines and higher unit costs from a slower ramp. However, the revised schedule also means extended inventory overhangs for titanium and other critical materials tied to the program. For titanium scrap suppliers, the Boeing 777X delivery delay prolongs weak spot demand and keeps pressure on prices that were already soft after earlier build-rate cuts.

Boeing will now send an updated production timetable to its vendors and negotiate adjustments case by case. Depending on each commodity, the impact may range from modest to significant, especially for high-value aerospace metals. Meanwhile, mills and scrap processors must recalibrate melt schedules and inventory strategies around a longer runway to meaningful 777X volume.

Single-aisle and 787 ramp offer partial offset

While the 777X stalls, Boeing’s narrowbody and mid-size widebody programs continue to climb. The FAA has lifted the 737 MAX output cap to 42 aircraft a month, up from 38, with Boeing targeting that rate by year-end. As a result, rising 737 MAX build rates will absorb more aluminium, titanium and nickel-based alloys, partly offsetting softness from the Boeing 777X delivery delay.

On the 787 Dreamliner, Boeing plans to exit the year at eight aircraft a month and reach 10 a month in 2026. However, the company warns that tighter inventory and seat certification issues could constrain the ramp. Even so, combined 737 MAX and 787 output, plus a 5,900-aircraft commercial backlog worth $535bn, underpins a multi-year demand floor for aerospace metals.

Boeing’s third-quarter losses narrowed to $5bn from $6bn a year earlier, while revenue rose 30pc to $23bn. Still, the Boeing 777X delivery delay highlights how certification risk can reshape earnings and capital allocation, with knock-on effects across engine makers, forgings, castings and metal supply chains.

The Metalnomist Commentary

The 777X remains Boeing’s most titanium-intensive platform, so each slip in its delivery profile matters for scrap and mill flows. For metals suppliers, resilience will depend on shifting focus toward single-aisle and 787 content while keeping optionality for a later 777X ramp. The broader lesson is clear: certification timelines are now a core variable in forecasting aerospace metals demand, not a background assumption.

AOG Technics Director Charged with Fraud Over Falsified Aircraft Parts

AOG Technics

UK SFO Investigation Triggers Global Safety Inspections and Legal Action

AOG Technics director charged with fraud by the UK’s Serious Fraud Office (SFO) in a case involving falsified documentation for aircraft parts. Jose Alejandro Zamora Yrala, the director of the UK-based supplier, is accused of operating the company for fraudulent purposes between 2019 and 2023. The SFO alleges that AOG Technics misrepresented the origin, status, or condition of jet engine parts, raising significant safety concerns across the aviation industry.

The SFO launched its investigation in December 2023 after safety alerts were issued by EASA, the UK Civil Aviation Authority, and the U.S. FAA. The alerts covered CFM56 engines used in commercial aircraft and GE CF6 engines in cargo jets. As a result, global operators and maintenance providers were instructed to review procurement records and inspect affected components. Several aircraft were grounded worldwide due to the discovery of fraudulently certified engine parts linked to AOG Technics.

Joint UK–Portugal Probe Continues as Court Date Set for June 2025

The investigation is being conducted jointly with Portuguese authorities, focusing on the suspected supply of forged safety certifications and counterfeit parts. Authorities have not ruled out additional charges or arrests as the probe continues. Meanwhile, Zamora Yrala is scheduled to appear in court on 2 June 2025. The case highlights growing concerns about counterfeit materials in aerospace supply chains and may lead to stricter traceability and verification standards across the aviation industry.

As the AOG Technics director is charged with fraud, this case underscores the critical need for transparency and compliance in high-risk sectors like aerospace maintenance and overhaul (MRO). The long-term reputational and regulatory consequences may extend well beyond the courtroom.

The Metalnomist Commentary

The AOG Technics scandal has exposed dangerous weaknesses in aviation’s aftermarket supply chain. As legal proceedings unfold, global regulatory agencies may push for blockchain-enabled traceability, supplier audits, and tamper-proof certification systems to prevent recurrence.

EASA Certification of Comac C919 Could Take Up to Six Years, Delaying Global Expansion

Comac C919

European Approval for China’s Flagship Jet Hinges on Extended Evaluation Timeline

The EASA certification of Comac C919 will require between three and six years, according to the European Union Aviation Safety Agency. The announcement underscores the regulatory hurdles facing China’s flagship single-aisle jet, which is currently certified only by the Civil Aviation Administration of China (CAAC). Without EASA approval, Comac’s C919 remains restricted to domestic operations, limiting its global commercial ambitions.

International Components, Domestic Ambitions

The C919 incorporates key systems from global suppliers, including CFM International’s LEAP-1C engine, avionics from Honeywell, GE Aerospace, and Collins Aerospace, and structural parts from various European and American firms. Despite this reliance on international technologies, EASA insists that it must independently verify the aircraft’s integration and design before granting certification. Comac has been commended for its transparency and proactive engagement with regulators.

Certification Timeline Reflects Political and Technical Complexities

The extended timeline for EASA certification of Comac C919 reflects both technical scrutiny and geopolitical realities. Comac’s absence from the FAA certification process indicates a strategic focus on Europe as its primary overseas market. However, in a protectionist trade environment, market access remains uncertain. As Comac seeks to challenge Airbus and Boeing in international markets, regulatory acceptance becomes a critical barrier.

The Metalnomist Commentary

The EASA certification of Comac C919 will be a litmus test for China’s global aerospace ambitions. While technical hurdles are expected, geopolitical headwinds may ultimately shape how far Comac can go in Western markets.

Rolls-Royce Maintains 2024 Engine Guidance Amid Strong Demand

Rolls-Royce Aircraft Engine

Rolls-Royce, the renowned UK-based aircraft engine manufacturer, has reaffirmed its 2024 guidance for original equipment (OE) deliveries and shop visits, citing robust demand in both business and widebody aviation sectors. The company remains confident in achieving its targets despite ongoing supply chain challenges affecting the aerospace industry.

Stable Outlook on Key Metrics

Rolls-Royce projects large engine flying hours to reach 100-110% of 2019 levels, alongside 500-550 OE deliveries and 1,300-1,400 shop visits. These projections align with its previous forecasts, underscoring sustained demand for widebody engines as global aviation recovers.

Additionally, Rolls-Royce is progressing toward FAA certification for an enhanced high-pressure turbine (HPT) blade for its Trent 1000 TEN engine, a critical development set to double the engine's "time on wing." Flight testing of the blade commenced earlier this year, marking a significant milestone in improving operational efficiency for engines powering the Boeing 787 Dreamliner.

Challenges and Competitive Landscape

While Rolls-Royce maintains steady guidance, the wider industry faces hurdles. Airbus, a key player in the aviation market, recently reported supply chain challenges that could impact its A350 widebody program, particularly in 2025. Despite these disruptions, Airbus targets a production rate of 12 A350s per month by 2028. Rolls-Royce’s titanium requirements, linked to the A350 program, are expected to dip in 2024 before rebounding in 2026.

The company's Trent 1000 engine competes directly with GE Aerospace’s GEnx for market share in powering the Boeing 787. However, Rolls-Royce remains unaffected by Boeing's delays in 777X deliveries, as this aircraft relies exclusively on GE's GE9X engines.

Rolls-Royce's resilience amid constrained supply chains highlights its strategic focus on innovation and maintaining strong relationships with aviation manufacturers. Its steady performance signals confidence in meeting rising demand for efficient, high-performance engines in the global aviation market.

French aerospace giant Safran Aircraft Engines has successfully acquired US-based Component Repair Technologies (CRT), enhancing its global maintenance, repair, and overhaul (MRO) operations. This strategic move is part of Safran’s ambitious €1 billion ($1.4 billion) plan to significantly broaden its presence in aerospace aftermarket services.

CRT, headquartered in Mentor, Ohio, employs over 450 skilled technicians and engineers specializing in aircraft engine repairs. The company maintains certifications from the Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA), guaranteeing compliance with rigorous international aerospace standards.

Boosting Repair Capabilities for Major Engine Components

Under Safran's ownership, CRT will focus on repairing critical engine components, including main, fan, compressor, and turbine shafts, alongside major cases and frames. This capability positions Safran to effectively respond to rising aftermarket service demands for the widely-used CFM56 and LEAP engines, which currently power approximately 32,000 aircraft globally.

Safran initiated the CRT acquisition process in September last year, underscoring the company's long-term commitment to expanding its aerospace repair capabilities and market presence throughout North America.

GTF Advantage Engine Certification signals new era for Pratt & Whitney

Pratt & Whitney

GTF Advantage engine certification in Europe marks a critical milestone for Pratt & Whitney and A320neo operators worldwide. The GTF Advantage engine certification from EASA, following earlier FAA approval, clears the way for entry into service from 2026. As a result, Pratt & Whitney strengthens its position in the narrow-body market against rival CFM’s Leap-1A engine.

Durability and efficiency at the heart of GTF Advantage engine certification

The upgraded design targets longer time on wing and lower lifecycle cost for airlines. Pratt & Whitney expects the GTF Advantage to double time on wing before major maintenance. As a result, operators gain fewer shop visits, lower unit costs and improved fleet availability. Meanwhile, the GTF Advantage engine certification reinforces confidence among lessors and financiers watching ongoing engine reliability debates.

Component enhancements focus on hotter sections where durability matters most. A redesigned airfoil in the high-pressure turbine helps reduce operating temperatures and manage thermal stress. Therefore, the engine can maintain performance over longer intervals with less degradation. Airlines flying dense A320neo schedules should benefit from higher dispatch reliability and more predictable MRO planning.

GTF Advantage engine certification reshapes narrow-body competition

The GTF Advantage will become Pratt & Whitney’s production standard for the Airbus A320neo family. This positions the engine as a direct, modernised challenger to CFM’s Leap-1A on the same platform. However, airlines will continue to weigh fuel burn, maintenance performance and OEM support before committing future fleet choices.

Narrow-body demand remains robust, with strong order backlogs and long delivery queues. As a result, even incremental gains from GTF Advantage engine certification can influence total cost of ownership over decades. For supply chains, higher time on wing may shift MRO demand timing, but it also locks in long-term parts and service revenue for RTX’s aftermarket network.

The Metalnomist Commentary

The GTF Advantage engine certification underscores how incremental turbine and materials engineering now drive competitive advantage in commercial aviation. If Pratt & Whitney delivers the promised durability in real-world service, the balance of power on the A320neo could tilt back toward the GTF. For metal and component suppliers, extended on-wing life will favour higher-value, longer-lasting alloys over pure volume growth.

Rolls-Royce’s Trent 1000 Engine Wins Regulator Approval

Rolls-Royce’s Trent 1000 Engine

Regulators Approve Trent 1000 Durability Upgrade

US and European aviation regulators have jointly certified Rolls-Royce’s new high-pressure turbine (HPT) blade for the Trent 1000 engine. The blade is part of a broader durability enhancement kit that also includes upgrades to the combustion system and fuel spray nozzle. Rolls-Royce expects the package to more than double the engine’s time on wing before major service.

The certification from the US Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA) enables Rolls-Royce to begin shipping upgraded engines to customers. New builds have already incorporated the improvements since January, while maintenance facilities worldwide have begun receiving retrofit kits.

Boosting Durability and Performance for the 787 Dreamliner

The Trent 1000, a competitor to GE Aerospace’s GEnx engine, powers Boeing’s 787 Dreamliner. The upgrade represents Rolls-Royce’s commitment to addressing past reliability issues with the engine, which has faced scrutiny over premature maintenance needs.

The first phase of upgrades improves cooling to the HPT blade by 40pc, while a second package set for 2026 is expected to add another 30pc to engine longevity through additional cooling and coating refinements. Rolls-Royce aims to retrofit its entire Trent 1000 fleet within the next two years.

Strategic Investment in Trent Engine Family

Rolls-Royce has pledged £1bn ($1.35bn) to enhance the durability of its Trent family engines, including the 7000, XWB-84, and XWB-97 models. The company expects these investments to extend overall engine durability by 80pc by 2027, reinforcing its competitive position in the widebody aircraft market.

By improving efficiency and reducing maintenance cycles, the upgrades aim to lower lifecycle costs for airlines while ensuring stronger reliability in long-haul operations. This move also comes ahead of rising demand for durable, efficient engines as global air travel continues its recovery.

The Metalnomist Commentary

Rolls-Royce’s certification for the Trent 1000 durability upgrade marks a crucial step in restoring airline confidence. By reducing maintenance burdens and extending time on wing, the firm not only strengthens its position against GE but also secures long-term service revenues. This investment underscores the industry’s shift toward performance-driven reliability as a competitive differentiator in aerospace engines.
