Amdt 3 (Continued)

             Compliance: 1. Unless previously accomplished, initiate the oil health-monitoring program within 100 hours' time in service from 26 March 1998.

           2. Unless previously accomplished, no later than 30 April 1998.

           This Amendment becomes effective on 9 August 2001.

 Background: A number of 4/5 bearing failures has resulted in separation of the LP turbine shaft.
           One failure of the LPT shaft led to an overspeed condition that resulted in an uncontained engine failure and subsequent aircraft damage.

           This amendment is issued to include the latest revisions of SBs ALF/LF 72-1030 and ALF/LF 72-1040, and reference the current FAA AD.

           Amendment 2 became effective on 7 September 2000 and included an additional SB reference to expand terminating action requirements.

           Amendment 1 became effective on 26 March 1998 and was issued to expand the applicability to include an additional engine model, to reference an FAA AD, to mandate the requirement to use oil filter by-pass valves previously mandated by AD/ALF/7, and to provide terminating action.
