Summary
The FAA proposes to adopt a new airworthiness directive (AD) for GEAE CF6-45A, 45A2, -50A, -50C, -50CA, -50C1, -50C2, -50C2B, - 50C2D, -50C2F, -50C2R, -50E, -50E1, -50E2, and -50E2B turbofan engines. This proposed AD would require replacing the compressor discharge pressure (CDP) restoring spring assembly on certain main engine controls (MECs) or re-marking MECs that already incorporate GEAE Service Bulletin (SB) No. CF6-50 S/B 73-0119, dated March 21, 2005. This proposed AD results from reports of five events involving fractured CDP restoring spring assemblies. We are proposing this AD to prevent loss of engine thrust control that could lead to loss of control of the airplane.
