EASA AD US-2019-01-01
[Correction] Powerplant - Airplane Flight Manual Revision
Summary
The Correction to Airworthiness Directive 2019-01-01 is a final rule issued by the Federal Aviation Administration (FAA) that applies to Boeing 787-8 airplanes powered by Rolls-Royce Trent 1000 series turbofan engines. This correction addresses an error in the original directive related to the identification of a referenced Rolls-Royce service bulletin. The directive requires revising the airplane flight manual to limit extended operations (ETOPS) for the affected aircraft and engines.
What Changed
This correction fixes the incorrect identification of a Rolls-Royce service bulletin in the original Airworthiness Directive 2019-01-01. The service bulletin number was mistakenly cited as "72-AK132" but the correct number is "72-K132." No other changes to the original directive were made.
Why It Matters
Accurate references to service bulletins are critical for operators and maintenance personnel to comply correctly with airworthiness directives. This correction ensures that operators of Boeing 787-8 aircraft with Rolls-Royce Trent 1000 engines can properly follow the required flight manual revisions to mitigate risks associated with engine failures during ETOPS. Compliance prevents potential unrecoverable thrust loss and enhances flight safety.
What To Do
Operators of affected Boeing 787-8 airplanes must revise the Certificate Limitations chapter of the airplane flight manual within 7 days after the effective date of February 4, 2019, incorporating the corrected information. They should replace any incorrect service bulletin references with the correct number "72-K132" to ensure compliance. Additionally, operators should consult the FAA contact for any alternative methods of compliance if needed.
