EASA sets 7,800-cycle inspection limit on Boeing 787 Trent 1000 discs

The European Union Aviation Safety Agency has issued an airworthiness directive, AD 2026-0117R1, that requires inspections of low-pressure turbine discs on Rolls-Royce Trent 1000 engines once they reach 7,800 engine flight cycles. The rule applies to engines fitted to Boeing 787 Dreamliners.
Rolls-Royce had marketed recent durability improvements to the Trent 1000 as allowing aircraft to remain in service for as long as six years between shop visits. The directive sets a firm inspection threshold for the affected discs, which is earlier than that interval would imply.
The order affects maintenance planning for European operators of the 787 and their engine overhaul schedules. The source material does not detail the inspection method or the reason for the cycle limit.
No compliance dates or further instructions from EASA are given in the source.
