Program and production

The 787 spent 2025 rebuilding credibility after a long stretch of delivery pauses and rework, and it largely succeeded. Then the first quarter of 2026 knocked output back below the target rate of eight per month.

The cause was engine supply. GEnx deliveries from General Electric fell behind, and because the GEnx powers the large majority of the in production fleet, the shortfall went straight through to airframe completion. Those delays have since eased, and Boeing's own count, published 13 October 2026, put September deliveries at eight 787s, matching the target rate for the first time this quarter, with 62 delivered in the first nine months of 2026.

The more stubborn problem is downstream of production. Delivery rates continue to lag production because of premium business class seat supply, an industry wide bottleneck that also affects Airbus widebodies but lands hard on the 787 because of how heavily the type is configured with lie flat business cabins.

In plain terms

Aircraft seats are certified parts. A business class seat with a bed function, an entertainment system and its own structure has to pass crash load testing before it can be installed. Seat makers have been a chokepoint across the industry, and that is why finished aircraft wait.

Technical and maintenance

Fan cowl cross engine debris protection, AD 2026-20-16, effective 23 November 2026. Adopted 19 October 2026 for 787-8, -9 and -10 airplanes with Rolls-Royce Trent 1000 engines, after the FAA found that the right engine's fan cowl does not sufficiently shield its oil lines and P30 sense line from debris thrown across the airplane if the left engine's intermediate pressure turbine fails, which the agency says could cause an in-flight shutdown of both engines. It requires a records check or inspection on an estimated 22 US registered aircraft, with a modification or replacement where an affected part is found. Boeing has not linked the gap to any in-service failure, and compliance follows Boeing's Special Attention Requirements Bulletin dated 19 February 2026, which calls for affected parts to be replaced by 2030.

On the line

Pull the right engine's fan cowl part number now rather than waiting for 2030. There is no interim inspection covering the gap, so an early swap closes out the exposure rather than just the paperwork.

Cargo liner joint sealing tape, AD 2026-20-01, effective 2 November 2026. Prompted by a report that cargo liner sealing tape could be missing forward of Door 1 on 787-8, -9 and -10 airplanes, which the FAA says could let a cargo hold fire propagate into the cabin overhead space. The directive requires inspection and installation of tape where missing, at an estimated 85 dollars per aircraft for the inspection alone.

Four earlier directives remain in force and unchanged this period: transponder loss in continuous wave interference (AD 2026-05-01), forward pressure bulkhead nonconformances found in production (AD 2025-23-05), shim gaps between composite structures (AD 2026-13-11), and withdrawn dispatch relief for a Trent 1000 with one bleed valve inoperative (AD 2026-19956). A fifth, AD 2026-20-10, orders fleet wide replacement of the outboard slat actuator, ending inspections in force since 2019 on roughly 174 US registered aircraft.

On the line

The transponder directive is a continued airworthiness item worth a second look despite its age. A unit that stops responding in a high interference environment is an air traffic separation problem, so confirm software or unit status against the AD rather than assuming an older directive is settled business.

Orders and operators

Widebody demand has held up well and the 787 remains the volume leader in its size class. The backlog is deep enough that new orders placed now deliver well into the 2030s.

The delivery constraint continues to shape operator behaviour. Airlines waiting on 787s have extended leases on 777-200ER and A330ceo aircraft rather than shrink capacity, which in turn keeps older widebodies flying longer than planned and sustains maintenance demand on those types.

Boeing and Biman Bangladesh Airlines announced a follow on order on 23 September 2026 for five more 787-10s and six 737-8s, bringing Biman's 2026 Boeing orders to 25 aircraft including an April order for eight 787-10s, two 787-9s and four 737-8s.

Safety

Germany's BFU accident investigation authority published an interim report on 28 September 2026 into a Vietnam Airlines 787-9 accident at Munich on 15 August 2026. Flight VN34 to Hanoi, carrying 271 passengers and 16 crew, rotated late departing runway 26L. The tail struck the ground and the aircraft continued past the paved runway end before becoming airborne from the grass beyond it, bursting four main landing gear tires, damaging the aft fuselage and striking approach lighting. Nobody was injured. The crew climbed away, dumped fuel and returned to Munich, landing safely about ninety minutes later.

Flight data showed movement of both brake pedals on the captain's side of the flight deck about three seconds after takeoff mode was activated, with further inputs recorded through the takeoff roll. The aircraft rotated at roughly 163 knots, below its calculated takeoff decision speed of 169 knots and rotation speed of 175 knots.

In plain terms

Takeoff decision speed, or V1, is the point beyond which a rejected takeoff is no longer assured to stop within the runway remaining. Here the aircraft left the ground before reaching either V1 or its rotation speed in the normal sense, which cut short the roll available before the tail struck.

BFU has not established whether the brake inputs came from pilot action, a technical fault or another cause, and said the cockpit voice recording of the takeoff had already been overwritten by the time the aircraft landed. The investigation continues.

An IndiGo 787-9 also returned to London Heathrow on 22 September 2026 after a smoke warning, landing safely with no injuries and no AAIB finding yet.

The live directives described above are continued airworthiness matters, unconnected to either occurrence.
