Airworthiness Directive · Amendment 39-10057 · General Electric Aircraft Engines CF700 Series Turbofan Engines
General Electric Aircraft Engines CF700 Series Turbofan Engines
General Electric Aircraft Engines (GE) CF700 series turbofan engines, installed on but not limited to Dassault- Aviation Fan Jet Falcon 20, and Sabreliner NA265 series aircraft.
This amendment adopts a new airworthiness directive (AD), applicable to General Electric Aircraft Engines CF700 series turbofan engines, that requires replacement of existing fan guards with new, improved fan guards. This amendment is prompted by a report of uncontained fan blades which separated from the engine during an overspeed. The actions specified by this AD are intended to prevent an overspeed of the aft fan disk from resulting in an uncontained engine failure and damage to the aircraft.
