Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to Rolls-Royce plc Tay 620-15, Tay 650-15, and Tay 651-54 series turbofan engines. This proposal would require 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 proposal is prompted by reports of broken strands and failed emergency fuel shutoff cables. The actions specified by the proposed 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.
