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 output has moved back toward eight per month. Boeing has spoken about reaching ten per month at some point, though the current focus is holding eight reliably.

The more stubborn problem is downstream of production. Delivery rates continue to lag production because of premium business class seat supply. This is an industry wide bottleneck rather than a Boeing specific one, and it affects Airbus widebodies too, but it lands hard on the 787 because of how heavily the type is configured with lie flat business cabins. An aircraft can be structurally complete and still sit on the ramp waiting for seats that have not cleared certification or have not been built.

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.

Boeing expects delivery volumes across both the 737 and 787 to rise through 2026, with the 787 accounting for roughly 15 percent of total annual deliveries.

Technical and maintenance

Two directives are worth knowing.

Transponder performance, AD 2026-05-01, effective 16 April 2026. This applies to 787-8, 787-9 and 787-10. It was prompted by multiple instances of transponder loss on aircraft entering airspace where continuous wave interference was present. In those conditions the transponder did not meet the minimum operational performance standard for response.

On the line

This is an avionics and software compliance item rather than a structural one, but do not treat it as minor. A transponder that stops responding in a high interference environment is an air traffic separation problem. Confirm the applicable software or unit status against the AD before releasing the aircraft, and check whether your fleet's configuration falls inside the effectivity.

Forward pressure bulkhead, AD 2025-23-05. Adopted after reports of multiple nonconformances in the forward pressure bulkhead, including excessive gaps and pull up. It requires internal and external detailed inspection for damage, with on condition actions. This is a manufacturing quality finding rather than an in service fatigue mechanism.

The FAA has also moved on shim gap manufacturing errors, mandating inspections after nonconforming gaps were found between composite structures during build. The common thread across all three items is that they originate in production quality rather than in service wear, which is consistent with the broader scrutiny the programme has been under.

A further directive, AD 2026-13-11, took effect on 1 July 2026 against the same three variants. Confirm its applicability against your serial numbers directly, because the published summary detail is thin.

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.

Safety

No significant developments since 21 September 2026.

No new accident investigation involving the type opened in this period. The live directives described above are being handled as continued airworthiness matters.
