the manufacturer's engine manual; and

        b) The part has accumulated more than 100 cycles-in-service since the last piece-part opportunity inspection, provided that the part was not damaged or related to the cause for its removal from the engine.

      The parts added to the table of this AD are identified by an asterisk (*) that precedes the part nomenclature.  Also, parts that have an Engine Manual Inspection Task and or Sub Task Number reference updated in the table of this AD, are identified by two asterisks (**) that precede the part nomenclature.

   AMOC's:

   AMOC's previously approved for FAA AD 2002-07-12, are also approved for this AD.

             Note 2:  FAA AD 2009-04-10 Amdt 39-15816 dated 5 February 2009 refers.

             Note 3:  This AD supersedes AD/CF6/46.
Compliance:  Fro Requirement 1 - Within 180 days after the effective date of this AD.

             For Requirement 2 - At each piece-part opportunity after Requirement 1 of this AD is completed.
             This Airworthiness Directive becomes effective on 9 April 2009.
Background:  This AD is superseding an existing airworthiness directive (AD) for General Electric Company (GE) CF6-80A, CF6-80C2, and CF6-80E1 series turbofan engines.  That AD required revisions to the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA) to include required inspection of selected critical life-limited parts at each piece-part exposure.

             This AD requires revisions to the CF6-80A, CF6-80C2, and CF6-80E1 series engines ALS sections of the manufacturer's manuals and an air carrier's approved continuous airworthiness maintenance program to incorporate additional inspection requirements, and to update certain Engine Manual Inspection Task and Sub Task Number references.

             This AD results from the need to require enhanced inspection of selected critical life-limited parts of CF6-80A, CF6-80C2, and CF6-80E1 series engines.  The issuing of this AD is intended to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the aeroplane.
