Statistics on Aircraft Gas Turbine Engine Rotor Failures That Occurred in U.S. Commercial Aviation during 1985

Abstract

This report presents statistics relating to gas turbine engine rotor failures which occurred during 1985 in U.S. commercial aviation service use. Two hundred and seventy-three failures occurred in 1985. Rotor fragments were generated in 150 of the failures, and of these 14 were uncontained. The predominant failure involved blade fragments, 94.4 percent of which were contained. Six disk failures occurred and all were uncontained. fifty-seven percent of the 273 failures occurred during the takeoff and climb stages of the flight. This service data analysis is prepared on a calendar year basis and published yearly. The data support flight safety analyses, proposed regulatory actions, certification standards, and cost benefit analyses. Keywords: Gas turbine rotors, Air transportation, Aircraft hazards, Aircraft safety, Containment.
