This report presents statistical information relating to gas turbine engine rotor failures which occurred during 1987 in U.S. commercial aviation service use. Three hundred thirty-two failures occurred in 1987. Rotor fragments were generated in 170 of the failures, and of these 12 were uncontained. The predominant failure involved blade fragments, 95 percent of which were contained. Four disk failures occurred and all were uncontained. Forty-nine percent of the 332 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.
