The report presents statistical information on the aircraft gas turbine engine rotor failures that occurred in U.S. commercial aviation during 1972. Based on FAA data, results are presented that establish 1 the incidence of rotor failure, 2 the type of fragments generated, 3 whether or not these fragments were contained, 4 the causes of failure, 5 where in the engine failure occurred, 6 what engines were affected and 7 what flight conditions prevailed at failure. The rate of uncontained rotor burst was considered to be significantly high. Blade fragments were generated in 95 of the rotor bursts, 20 of which were uncontained. Although fewer disk and rim fragment bursts occurred, none were contained. Author
