<summary>The FAA proposes to adopt 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 proposed AD would require removing from service, AFT Technologies combustion liners, P/N AFT-5016T30G02. This proposed 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 proposing 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.</summary>
<dates>We must receive any comments on this proposed AD by November 9, 2009.</dates>
