* The FAA has determined that up to three Stage 2 Turbine wheels, SN GATWZA9723, may have been distributed with
three different P/N's. Therefore, while only P/N 646C596P1 is an approved P/N for the CJ610 and CF700 model
engine, all three part numbers are listed.
This amendment adopts a new airworthiness directive (AD) that is applicable to GE Aircraft Engines (GEAE) CJ610 series turbojet and CF700 series turbofan engines. This action requires removal of certain unapproved parts before further flight. This amendment is prompted by findings that life-limited parts, with forged and inaccurate records, have been introduced into the field and might be installed on the affected engines. The actions specified in this AD are intended to prevent the use of unapproved parts. This condition, if not corrected, could lead to an uncontained engine failure and damage to the airplane.
Required as indicated, unless accomplished previously.
To prevent the use of unapproved parts, which could lead to an uncontained engine failure and damage to the airplane, accomplish the following:
Replacement of Unapproved Parts
(a) Before further flight after the effective date of this AD, remove any part listed by P/N and SN in Appendix 1 of this AD, and replace it with a serviceable part.
Alternate Methods of Compliance
