Rolls-Royce Proposes Supersession of Airworthiness Directive for Certain Turbofan Engines

Rolls-Royce Deutschland Ltd & Co KG is proposing to supersede an existing airworthiness directive for its BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines, which would restrict the applicability to engines exposed to silver plated nuts and remove the requirement for removal from service of certain high-pressure compressor stages 1 to 6 rotor disc assemblies before exceeding certain thresholds, in order to prevent failure of the high-pressure compressor stages 1 to 6 rotor disc assembly and potential uncontained engine failure and damage to the airplane.
