Boeing Opens Everett North Line, First 737 Production Outside Renton Since 1970
Boeing loaded the first 737 Max 10 fuselage onto its new “North Line” assembly facility at Everett, Washington, on July 6, marking the first 737 production outside the Renton plant since consolidation there in 1970. The $1 billion fourth assembly line represents the single largest expansion of 737 manufacturing capacity in decades, intended to support FAA authorization to build up to 47 aircraft per month by 2027 and eventually 52 per month. The initial airframe, destined for WestJet, is a low-rate production aircraft; the line will initially handle Max 8 and Max 9 variants before transitioning to Max 10 exclusivity. Full capacity is months away.

FAA AD Mandates Helicopter Yaw Pedal Damper Inspections After Tail Rotor Authority Loss
The FAA issued an airworthiness directive effective July 9 for several helicopter models following a confirmed in-flight loss of tail rotor authority traced to auxiliary system fluid loss. Investigators found that a fatigue fracture in the yaw pedal damper housing and a concurrent fatigue fracture of the attachment bolt allowed hydraulic fluid to escape, eliminating yaw control authority. The AD mandates repetitive visual inspections of the auxiliary servo assembly and a fluorescent penetrant inspection of the yaw pedal damper housing, with corrective replacement required if damage is detected. Tail rotor loss of control is classified as a critical failure mode and typically leaves little time for crew recovery.

AAIB: 737 Max 8 Crew Failed to Update Thrust Data After Switching to Intersection Departure at Luton
UK Air Accidents Investigation Branch investigators determined that the crew of an Ascend Airways Boeing 737 Max 8 failed to update performance data after switching from a full-length runway departure to an intersection departure at London Luton in April 2025. The crew accepted an intersection A departure from runway 25, reducing available runway distance to 1,771 metres — 345 metres less than the full length — without entering revised V-speeds into the flight management computer. Maximum thrust during the roll was 82.1% against a required 85.2%, and the aircraft lifted off 162 metres from the runway end with 162 passengers and six crew aboard. No injuries occurred.

EASA AD 2026-0134 Revises A320 Elevator Aileron Computer Compliance Requirements
EASA issued AD 2026-0134 for certain Airbus A320 family aircraft, superseding Emergency Airworthiness Directive 2025-0268-E that was published November 28, 2025. The original emergency directive addressed a flight-control software vulnerability in the elevator aileron computer — which manages pitch and roll authority — identified following a JetBlue incident on October 30, 2025. The superseding AD provides compliance clarifications and introduces alternative methods of compliance allowing operators greater flexibility in meeting the requirements while maintaining equivalent safety. The A320 family is the world’s most widely operated narrowbody airliner, making software and avionics directives of this type among the broadest-reach regulatory actions in commercial aviation.
KLM A321neo Tail-Strike Probe Transferred to Dutch Safety Board After Lisbon Landing Damage
Portuguese investigation authority GPIAAF has transferred responsibility for the probe into a KLM Airbus A321neo tail-strike at Lisbon on June 16 to the Dutch Safety Board. The aircraft, PH-AXB, sustained structural damage to its aft fuselage underside during landing and was removed from service for damage assessment and repair. No occupants were injured. Portuguese investigators determined the event was “contained in nature” based on landing dynamics, flight recorder data, and crew information, and elected to transfer the investigation given that KLM is a Dutch operator. Aft fuselage tail-strikes require detailed composite and metallic structure inspection to rule out internal delamination and frame damage not visible externally.

Rolls-Royce Designates XWB-84 EP as Sole A350-900 Engine Offering After 1.8% Fuel Burn Confirmation
Rolls-Royce has designated the Trent XWB-84 Enhanced Performance (EP) variant as the sole engine it will offer for future A350-900 sales campaigns, effectively retiring the baseline model for new commitments. The EP has delivered average in-service fuel burn savings of approximately 1.8% — nearly double the 1% originally forecast — since entering revenue service with Delta Air Lines in 2025. At current fuel prices, a 1.8% reduction equates to roughly $500,000 per aircraft per year. Rolls-Royce will continue building baseline XWB-84 engines to fulfil existing committed orders alongside the EP, with production concentrated at Derby, UK, and a new capacity addition planned at Dahlewitz, Germany, later this decade.

GKN and University of Nottingham Form HPDrive Technologies to Commercialise Cryogenic Electric Motors
GKN Aerospace and the University of Nottingham have established a joint venture, HPDrive Technologies, to commercialise cryogenic-cooled superconducting electric motors developed under the UK-funded H2GEAR hydrogen propulsion programme. The 60 kW prototype completed at the University of Manchester demonstrated approximately 99% electrical efficiency during testing. A larger 1 MW variant was subsequently built at GKN’s Global Technology Centre in Bristol but did not operate due to regulatory delays in acquiring rare-earth metals for the magnets. GKN defended its continued investment in hydrogen propulsion research, noting that the JV signals confidence in the long-term commercial potential of cryogenic electric drives for commercial aircraft.

Airbus Forecasts 42,060 Deliveries Through 2045 as Aging Fleet Replacement Drives Nearly Half of Demand
Airbus projects demand for 42,060 new passenger airliners between 2026 and 2045 in its annual Global Market Forecast, driven by a projected doubling of revenue passenger kilometres to 21.3 trillion over the period. Nearly half of deliveries — 19,820 aircraft — will replace ageing jets rather than expand fleets, a shift reflecting that the proportion of in-service airliners under 10 years old fell from 63% to 53% between 2015 and 2025. Single-aisle aircraft account for 15,580 deliveries; widebodies for 4,240. Airbus identifies growth in thinner long-haul routes and capacity demands in Asia, where China and India alone account for more than 12,300 deliveries.
