E7-17682 Airworthiness Directives; General Electric Company (GE) CF6-80C2 and CF6-80E1 Series Turbofan Engines Proposed Rule The FAA proposes to adopt a new airworthiness directive (AD) for GE CF6-80C2 and CF6-80E1 series turbofan engines with fuel manifold part numbers (P/Ns) 1303M31G12 and 1303M32G12 installed. This proposed AD would require removing and discarding the loop clamps that assemble the fuel manifold to the compressor rear frame (CRF) friction damper brackets, visually inspecting the fuel manifold for wear at each clamp location, and replacing the clamps with new, zero-time parts. This proposed AD results from fuel manifold vibration during engine operation that causes the loop clamps that assemble the manifold to the CRF to deteriorate. Fourteen fuel leak events occurred over the past several years. We are proposing this AD to prevent fuel leaks during engine operation that could result in an under-cowl fire. 2007-09-07 2007 9 https://www.federalregister.gov/documents/2007/09/07/E7-17682/airworthiness-directives-general-electric-company-ge-cf6-80c2-and-cf6-80e1-series-turbofan-engines https://www.govinfo.gov/content/pkg/FR-2007-09-07/pdf/E7-17682.pdf Transportation Department; Federal Aviation Administration 492,159 The FAA proposes to adopt a new airworthiness directive (AD) for GE CF6-80C2 and CF6-80E1 series turbofan engines with fuel manifold part numbers (P/Ns) 1303M31G12 and 1303M32G12 installed.
