What to do
Operators must replace components before exceeding life limits and perform all applicable maintenance tasks within specified intervals as per the updated TLM. Any discrepancies found during inspections require corrective actions according to Rolls-Royce approved documentation. Additionally, the approved Aircraft Maintenance Programme must be revised within 12 months of the effective date to incorporate the new limitations and tasks.
Summary
EASA Airworthiness Directive 2022-0248 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Rolls-Royce Deutschland Ltd & Co KG Trent 7000-72 and Trent 7000-72C engines. It mandates compliance with updated maintenance tasks and life limits as specified in the Rolls-Royce Trent 7000 Time Limits Manual Revision 14 dated 22 July 2022. This directive ensures continued airworthiness by requiring operators to follow the latest maintenance program amendments.
What changed
EASA AD 2022-0248 supersedes the previous AD 2020-0244 and introduces new and more restrictive maintenance tasks and life limits for the Trent 7000 engines. The changes include additions such as inspections of high pressure nozzle guide vane flap seals and convex aerofoils, overhaul limits for fuel pumps, and clarifications on component interchangeability. These updates are incorporated in the latest TLM Revision 14.
Why it matters
This directive is critical for aviation professionals because it enforces updated maintenance requirements that prevent unsafe conditions caused by component failures or exceeded life limits. Operators and maintenance organizations must adhere to these revised tasks to ensure engine reliability and regulatory compliance. Failure to comply could compromise aircraft safety and lead to regulatory penalties.
