What to do
Operators of affected Rolls-Royce Trent 1000 and Trent 7000 engines must perform initial and repetitive inspections of the IPC front air seal within specified engine flight cycle intervals starting no later than 26 September 2024. If cracks are detected, the engine must be removed from service and repaired before further flight. Group 2 engines may optionally be modified to Group 1 standards and then inspected accordingly.
Summary
EASA Airworthiness Directive 2024-0178 is an airworthiness directive addressing the inspection of the intermediate pressure compressor (IPC) shaft assembly front air seal on Rolls-Royce Trent 1000 and Trent 7000 engines. These engines are commonly installed on Boeing 787 and Airbus A330 aircraft. The directive mandates repetitive inspections to detect cracks that could lead to engine failure and potential safety risks.
What changed
This new directive introduces mandatory repetitive visual inspections of the IPC shaft assembly front air seal on affected engines, with specific compliance times based on engine flight cycles and service bulletin embodiment. It also allows for in-shop inspections and provides corrective actions including engine removal and part replacement if cracks are found. Additionally, it permits modification of Group 2 engines to Group 1 standards, which then require the same inspection regime.
Why it matters
This directive is critical for aviation professionals to prevent potential engine failures caused by cracked IPC shaft assembly front air seals, which could lead to high-energy debris release and engine in-flight shutdowns. Operators and maintenance teams must ensure compliance to maintain aircraft safety and airworthiness. Failure to comply could result in unsafe conditions and regulatory non-compliance.
