EASA AD 2025-0086
Time Limits / Maintenance Checks — Engine Time Limits Manual — Amendment
Summary
EASA Airworthiness Directive 2025-0086 is an amendment addressing time limits and maintenance checks for Rolls-Royce Deutschland BR700-715 engines, specifically models BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30, commonly installed on Boeing 717 aircraft. This directive mandates compliance with the updated BR715 Time Limits Manual Revision 68 to ensure continued airworthiness. It replaces previous emergency directives and updates maintenance requirements for these engines.
What Changed
This amendment supersedes the earlier EASA Emergency AD 2007-0116-E and introduces new and more restrictive maintenance tasks and life limits as specified in the latest BR715 Time Limits Manual Revision 68. It requires operators to replace components before exceeding new life limits and to perform maintenance tasks within updated thresholds and intervals. Additionally, it mandates revising the Aircraft Maintenance Programme within 12 months to incorporate these changes.
Why It Matters
Compliance with EASA AD 2025-0086 is critical for aviation professionals to maintain engine safety and airworthiness of affected Boeing 717 aircraft. The updated maintenance tasks and life limits reduce the risk of unsafe conditions caused by component failures. Operators, maintenance organizations, and compliance teams must adapt their maintenance programs to meet these stricter requirements to avoid regulatory violations and ensure operational safety.
What To Do
Operators must replace engine components before exceeding the new life limits and perform all maintenance tasks within the specified intervals starting from 30 April 2025. Any discrepancies found during inspections must be corrected within the prescribed times or before the next flight if no time is specified. Additionally, the approved Aircraft Maintenance Programme must be revised within 12 months after the effective date to include the updated tasks and limitations from the BR715 Time Limits Manual Revision 68.
