This amendment adopts a new airworthiness directive (AD) that is applicable to General Electric Aircraft Engines (GEAE) CJ610 series turbojet and CF700 series turbofan engines. This action requires operators to remove and replace with serviceable parts unapproved combustion liner assemblies prior to further flight. This amendment is prompted by findings that unapproved combustion liner assemblies are installed on the affected engines. The actions specified in this AD are intended to prevent combustor liner cracking at multiple locations, progressing to liner fragmenting and combustor casing burnthrough, which could result in an engine fire.
