Description
China Airlines flight 012, encountered moderate turbulence at flight level 330. The airplane subsequently departed controlled flight and sustained damage to the left and right outboard elevator skin assemblies, portions of which separated from the airplane. The airplane continued on and landed uneventfully at Anchorage, AK. PROBABLE CAUSE: “The flight control force characteristics of the MD-11 airplane in high altitude cruise flight. The upset was induced by a moderate lateral gust and was exacerbated by excessive control deflections. Contributing to the incident was a lack of pilot training specific to the recovery from high altitude, high speed upsets in the MD-11.”
Primary Cause
The flight control force characteristics of the MD-11 airplane in high altitude cruise flight, combined with a moderate lateral gust and excessive control deflections, induced the upset. Lack of pilot training specific to recovery from high altitude and high speed upsets in the MD-11 contributed to the incident.The flight control force characteristics of the MD-11 airplane in high altitude cruise flight, combined with a moderate lateral gust and excessive control deflections, induced the upset.
