Engine – Low Pressure Turbine Discs – Inspection
EASA Airworthiness Directive 2026-0117R1 is an updated safety directive addressing inspection requirements for low pressure turbine stage 3 and stage 4 discs on Rolls-Royce Trent 1000 engines, commonly installed on Boeing 787 aircraft. The directive mandates inspections to detect cracks caused by rubbing contact with interstage static seals to prevent potential turbine disc failure. It applies to all serial numbers of Trent 1000-A2 through Trent 1000-L2 engine variants.
