Airworthiness Directives; Rolls-Royce plc Tay 620-15, Tay 650-15, and Tay 651-54 Series Turbofan Engines

Resumen

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.
