Light Twin-Engine Aircraft Accidents Following Engine Failures, 1972-1976

摘要

The National Transportation Safety Board has studied the data collected during the investigation of 477 light-twin aircraft accidents from 1972 through 1976 which involved engine failure or malfunction. The complete records of particularly pertinent accidents were studied in detail. Pilot handbooks and other sources which provide information on engine-out performance and emergency procedures in light-twins were reviewed. A limited number of interviews with pilots and instructors were conducted. FAA training regulations were also studied. A major conclusion of the study is that many of these accidents involved a lack of pilot proficiency in managing a light-twin after loss of power in one engine. Four recommendations are made to the FAA for corrective action and one previously made recommendation is reiterated.
