Two of these were found to be caused by structural failure resulting from metal fatigue in the airframe, a phenomenon not fully understood at the time; the other was due to overstressing of the airframe during flight through severe weather. The Comet was withdrawn from service and extensively tested.
1 de jun. de 1997 · Fatigue failure of the de Havilland Comet I 151 area was recognized as a prime site for fatigue failure initiation, and de Havilland subsequently redesigned the windows and increased the thickness of the skin in these areas to prevent this occurring on later Comet aircraft.
