Airworthiness Directive · Amendment 39-16273 · General Electric Company (GE) CJ610 Series Turbojet Engines and CF700 Series Turbofan Engines
General Electric Company (GE) CJ610 Series Turbojet Engines and CF700 Series Turbofan Engines
This AD applies to GE CJ610 series turbojet and CF700 series turbofan engines with AFT Technologies combustion liner, part number (P/N) AFT-5016T30G02, installed. These engines are installed on, but not limited to, Learjet Inc. model 24 series and model 25 series airplanes, Dassault Aviation Fan Jet Falcon series airplanes, and Sabreliner Corporation NA-265-70 and NA-265-80 series airplanes.
The FAA is adopting a new airworthiness directive (AD) for GE CJ610 series turbojet engines and CF700 turbofan engines with AFT Technologies combustion liners, part number (P/N) AFT-5016T30G02. This AD requires removing from service, AFT Technologies combustion liners, P/N AFT-5016T30G02. This AD results from a report of an AFT Technologies combustion liner that released a large section of the inner combustion liner and reports of six combustion liners with premature cracks. We are issuing this AD to prevent premature cracks in the combustion liner, which could release pieces of the inner combustion liner. A release of pieces of the inner combustion liner could cause an uncontained failure of the engine turbine and damage to the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
For engines that have an AFT Technologies combustion liner, P/N AFT-5016T30G02, with fewer than 200 hours-since-new (HSN) or 300 cycles-since-new (CSN), remove the AFT Technologies combustion liner, P/N AFT-5016T30G02, before exceeding 200 HSN or 300 CSN, whichever occurs first.
(g) For engines that have an AFT Technologies combustion liner, P/N AFT-5016T30G02, with 200 HSN or more or 300 CSN or more, remove the AFT Technologies combustion liner, P/N AFT-5016T30G02, within 15 hours-in-service or 10 cycles-in-service, after the effective date of this AD, whichever occurs first.
(h) After the effective date of this AD, don't install any AFT Technologies combustion liner, P/N AFT-5016T30G02, in any engine.
