Abstract : A world-wide survey was done of serious aircraft accidents involving fatigue fracture. Volume 1 of the report deals with fixed-wing aircraft, while Volume 2 addresses rotary-wing aircraft. A total of 1466 fixed-wing accidents since 1927 were identified as having fatigue fracture as a related cause, and these accidents resulted in 1861 fatalities. The accidents cover civil and, to a limited extent, military aircraft. Accidents are listed by failure type, as well as by aircraft type. Engine/transmission failure and landing-gear failure were the most common cause of recent fixed-wing accidents, and currently there is an average of about 69 fixed-wing fatigue accidents per year.
