Abstract
The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-80E1A2 and -80E1A4 turbofan engines with left vertical link bolts part number (P/N) 1304M26P02 installed, and pylon attachment bolts originally torqued to 450-500 lb ft. This AD requires reducing the torque of pylon attachment bolts, and replacing left vertical link bolts with life-limited serialized bolts. This AD results from revised analyses by the airframe manufacturer of loads on the forward engine mount. We are issuing this AD to prevent engine separation that could result from a reduction of engine mount structural integrity due to failure of pylon attachment bolts or vertical link bolts.
