E7-20036 Airworthiness Directives; General Electric Company (GE) CF6-80C2A5F Turbofan Engines Rule The FAA is adopting a new airworthiness directive (AD) for GE CF6-80C2A5F turbofan engines installed on, but not limited to, Airbus A300F4-605R airplanes. This AD requires removing previous software versions from the engine electronic control unit (ECU). Engines with new version software will have increased margin to flameout. This AD results from reports of engine flameout events during flight, including reports of events where all engines simultaneously experienced a flameout or other adverse operation. Although the root cause investigation is not yet complete, we believe that exposure to ice crystals during flight is associated with these flameout events. We are issuing this AD to minimize the potential of an all-engine flameout event caused by ice accretion and shedding during flight. 2007-10-11 2007 10 https://www.federalregister.gov/documents/2007/10/11/E7-20036/airworthiness-directives-general-electric-company-ge-cf6-80c2a5f-turbofan-engines https://www.govinfo.gov/content/pkg/FR-2007-10-11/pdf/E7-20036.pdf Transportation Department; Federal Aviation Administration 492,159 The FAA is adopting a new airworthiness directive (AD) for GE CF6-80C2A5F turbofan engines installed on, but not limited to, Airbus A300F4-605R airplanes.
