Abstract : This report presents statistical information relating to the number of gas turbine engine rotor failures which occurred during 1979 in commercial aviation service use. The predominant failure mode involved blade fragments, 84 percent of which were contained. No uncontained disk failures occurred and although fewer rotor rim and seal failures occurred, 100 percent and 50 percent, respectively, were uncontained. Sixty-eight percent of the 157 rotor failures occurred during the take-off and climb stages of flight. (Author)
