EASA AD 2024-0136
Time Limits / Maintenance Checks — Time Limits Manual / Maintenance Programme — Amendment
Summary
EASA Airworthiness Directive 2024-0136 is an amendment concerning the Rolls-Royce Deutschland BR700-725A1-12 engines, commonly installed on Gulfstream G650 aircraft. This directive mandates compliance with the updated Time Limits Manual (TLM) Revision 27, which contains mandatory airworthiness limitations and maintenance tasks. The directive ensures continued airworthiness by enforcing updated maintenance schedules and life limits for engine components.
What Changed
EASA Airworthiness Directive 2024-0136 introduces new and more restrictive maintenance tasks and life limits for the BR700-725A1-12 engines as specified in the latest TLM Revision 27. It requires operators to replace components before exceeding updated life limits and to perform maintenance tasks within revised thresholds and intervals. The directive also mandates updating the Aircraft Maintenance Programme (AMP) within 12 months to incorporate these changes.
Why It Matters
This directive is critical for aviation professionals because it enforces compliance with updated mandatory maintenance requirements to prevent unsafe conditions. Operators and maintenance organizations must adhere to these revised limits to ensure engine reliability and regulatory compliance. Failure to comply could result in unsafe operations and regulatory penalties.
What To Do
Operators of aircraft equipped with BR700-725A1-12 engines must replace components before exceeding the new life limits and complete all maintenance tasks within the specified intervals starting from 25 July 2024. They must revise their approved Aircraft Maintenance Programme to incorporate the updated tasks and limitations within 12 months of the effective date. Any discrepancies found during maintenance must be corrected according to approved Rolls-Royce Deutschland instructions before further flight.
