Abstract : This report presents statistical information relating to gas turbine engine rotor failures which occurred during 1989 in U.S. commercial aviation service use. Four hundred and thirty-five failures occurred in 1989. Rotor fragments were generated in 156 of the failures, and of these 24 were uncontained. The predominant failure involved blade fragments, 87 percent of which were contained. Eight disk failures occurred and six were uncontained. Thirty-six percent of the 435 failures occurred during the takeoff and climb stages of flight. This service data analysis is prepared on a calendar-year basis and published yearly. The data are useful in support of flight safety analyses, proposed regulatory actions, certification standards, and cost benefit analyses.
