Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to General Electric Company (GE) CF6- 80A series turbofan engines. This proposal would require an initial and repetitive on-wing eddy current inspection or an on-wing spot fluorescent penetrant inspection of the compressor rear frame (CRF) midflange for cracks, and replacement, if [[Page 9793]] necessary, with serviceable parts. This proposal would also require removal from service of certain CRF's as a terminating action to the on-wing inspection program. This proposal is prompted by a report of a CRF separation that resulted in a rejected takeoff. The actions specified by the proposed AD are intended to prevent a CRF separation, which could result in a rejected takeoff and damage to the aircraft.
