EASA AD 2022-0232
Time Limits / Maintenance Checks — Time Limits Manual / Maintenance Programme — Amendment
Summary
EASA Airworthiness Directive 2022-0232 is an amendment concerning the Rolls-Royce RB211-524G and RB211-524H engine models, commonly installed on Boeing 747 and Boeing 767 aircraft. This directive updates the Time Limits Manual and Maintenance Programme to include new and more restrictive maintenance instructions and life limits for engine components. It mandates compliance with these updated maintenance requirements to ensure continued airworthiness.
What Changed
This amendment supersedes the previous EASA AD 2013-0246 and incorporates the latest Rolls-Royce RB211-524G/H Time Limits Manual revision 63 dated 20 July 2022. It introduces new and more restrictive maintenance tasks and life limits for engine parts, including replacement thresholds and intervals. Operators must now follow these updated instructions to maintain compliance.
Why It Matters
For aviation professionals, this directive ensures that maintenance programs reflect the latest safety-critical life limits and inspection tasks, reducing the risk of engine failures. Operators and maintenance organizations must update their maintenance schedules and procedures accordingly to remain compliant with EU regulations. Failure to comply could result in unsafe conditions and regulatory penalties.
What To Do
Affected operators must replace components before exceeding the new life limits and perform maintenance tasks within specified intervals as detailed in the updated Time Limits Manual. They must revise their approved Aircraft Maintenance Programme within 12 months of the effective date to incorporate these changes. Any discrepancies found during maintenance require corrective actions per Rolls-Royce instructions before further flight.
