Notes

Note1: These component parts have not had cyclic life limits assigned, but may be subject to failure as a result of undetected abuse and unpredictable contingencies. Therefore, to provide a record of service experience and cycles (partial cycle counting does not apply), a Life Limit Part Log Card must be maintained. If the part is removed, the Life Limit Part Log Card must be updated and stay with that part.

  • HPC Radial Impeller Assembly Part Number. No part number in the component part log. AD Logbook Research Discrepancies:
  1. AD No. 2005-13-07 (Amendment 39-14143) dated July 27, 2005 - This AD results from a report of an uncontained failure of an LP 2nd stage turbine rotor disc that resulted in an in-flight engine shutdown. We are issuing this AD to prevent LP turbine rotor disk separation, which could result in an uncontained engine failure and damage to the airplane. No sign off found.

    Note: SB TFE731-72-3682 - P/C/W Not Applicable

  2. AD No. 2010-06-11 (Amendment 39-16235) dated April 21, 2010 - This AD results from a report of cracks found during a fluorescent penetrant inspection (FPI) of the disc bore. We are issuing this AD to prevent an uncontained failure of a second stage LPCR disc and/or a third stage LPCR disc due to cracks in the bore, which could result in damage to the airplane. No sign off found.
