An accelerated mission test AMT of a TF41 SN 142163 was conducted in the Air Force Aero Propulsion Laboratorys D Bay Sea-Level Engine Test Facility between 2 August 1978 and 20 September 1978. The primary objective of the test was to evaluate the structural reliability of a series of parts changes known as Block 76 hardware. A two-hundred-sixty-three hour test program was initially planned but only one-hundred-eighty-nine hours were actually completed due to the failure of a first stage high pressure turbine blade. Post-test teardown showed all of the Block 76 hardware to be in good condition. Engine performance deterioration was tracked and an exhaust gas temperature survey was performed and the data analyzed. This report describes the details of the test, including test objectives, approach, instrumentation, facility and results. Author
