Airworthiness Directive · Amendment 39-11423 · Rolls-Royce plc Tay 620-15, Tay 650-15, and Tay 651-54 Series Turbofan Engines
Rolls-Royce plc Tay 620-15, Tay 650-15, and Tay 651-54 Series Turbofan Engines
Rolls-Royce plc (R-R) Tay 620-15, Tay 650-15, and Tay 651-54 series turbofan engines, installed on but not limited to Fokker F.28 Mark 0070 series, Fokker F.28 Mark 0100 series, and Boeing 727 series aircraft modified with STC SA8472SW.
This amendment adopts a new airworthiness directive (AD), applicable to Rolls-Royce plc Tay 620-15, Tay 650-15, and Tay 651-54 series turbofan engines, that requires initial and repetitive visual inspections of the emergency fuel shutoff cable for broken strands or failed cables, and, if necessary, replacement with serviceable parts. This amendment is prompted by reports of broken strands and failed emergency fuel shutoff cables. The actions specified by this AD are intended to prevent emergency fuel shutoff cable failure, which could result in the non-operation of the emergency fuel shut-off system in the event of a low pressure shaft failure.
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.
