EASA AD 2026-0117
Engine – Low Pressure Turbine Discs – Inspection
EASA Airworthiness Directive 2026-0117 is an airworthiness directive addressing inspection requirements for Rolls-Royce Trent 1000 series engines installed on Boeing 787 aircraft and potentially other types. It mandates inspections of low pressure turbine stage 3 and stage 4 discs, specifically parts with P/N KH36323 and KH33943, to detect cracks caused by rubbing contact with interstage static seals. The directive aims to prevent turbine disc failure and potential damage to the aircraft.
