Airworthiness Directive · Amendment 39-15819 · Rolls-Royce Deutschland Ltd & Co KG, BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 Turbofan Engines
Rolls-Royce Deutschland Ltd & Co KG, BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 Turbofan Engines
Superseded. A later AD replaced this one: AD 2026-21-04. Comply with the one in force.
This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD), BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines, with a low pressure (LP) compressor (fan) disc assembly, part number (P/N) BRH10048 or P/N BRH19253. These engines are installed on, but not limited to, McDonnell Douglas Corporation model 717-200 airplanes.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Within 25 flight cycles after the effective date of this AD, do the following actions, unless already done.
(1) Amend the Airworthiness Limitations Section (ALS) of the Time Limits Manual SUBTASK 05-10-01-860-016, by revising the “GIVEN LIFE A1-30 RATING (FLIGHT CYCLES)” for both the LP compressor (fan) disc assembly P/N BRH10048 and LP compressor (fan) disc assembly P/N BRH19253 from 33,000 flight cycles to 25,000 flight cycles.
(2) Check the lifing of both the LP compressor (fan) disc assembly P/N BRH10048 and LP compressor (fan) disc assembly P/N BRH19253 if the relevant compressor (fan) disc assembly is currently installed or was previously installed, in the BR700-715A1-30 engine model and operated under the Hawaiian Flight Mission.
(3) Remove the relevant compressor (fan) disc assembly from service before further flight, if the consumed life has exceeded the maximum approved life specified in the ALS.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
