What to do
Operators must remove affected Trent 1000 engines from service by the dates specified in Appendix 1 of Rolls-Royce Alert NMSB TRENT 1000 72-AK294 unless the affected part passes the on-wing thickness inspection per the latest service bulletin revision. Replacement of affected low pressure compressor front cases is required before engine return to service unless the part is eligible and passes inspection. Installation of affected parts is prohibited unless they meet inspection requirements. Compliance deadlines vary by engine serial number as detailed in the service bulletin.
Summary
EASA Airworthiness Directive 2019-0286R2 addresses the removal from service of low pressure compressor front cases with specific part and serial numbers installed on Rolls-Royce Trent 1000 series engines, commonly found on Boeing 787 aircraft. The directive mandates inspections and replacement of affected parts to ensure engine safety and continued airworthiness. It applies to all serial numbers of Trent 1000 engines listed in the associated Rolls-Royce Alert Non-Modification Service Bulletin TRENT 1000 72-AK294.
What changed
EASA Airworthiness Directive 2019-0286R2 revises the previous version by introducing provisions for on-wing ultrasonic thickness inspections of certain affected low pressure compressor front cases. This allows some engines to remain in service longer if the parts pass the inspection, rather than requiring immediate removal from service. The revision updates compliance options and extends the inspection criteria based on the latest Rolls-Royce service bulletin revision.
Why it matters
This directive is critical for aviation professionals because it addresses a potential unsafe condition that could lead to high-energy debris release in the event of a fan blade failure, risking damage to the aircraft and loss of control. Operators and maintenance organizations must comply to maintain airworthiness and avoid unplanned engine removals or failures. The updated inspection options provide more flexibility, potentially reducing downtime and maintenance costs while ensuring safety.
