Talk:Air Moorea Flight 1121/Temp

The accident was investigated by the French Bureau d'Enquêtes et d'Analyses (BEA). The BEA discovered that the elevator cable failed during flight, leading to a loss of pitch control and causing the aircraft to crash 68 seconds after the start of the takeoff roll. Further investigation revealed that the cable on the accident aircraft was stainless steel, which is more susceptible to wear than the carbon steel the airline used on its other Twin Otter aircraft. However, the wear alone combined with normal forces experienced during operation could not explain the cable failure. Instead, the BEA concluded that the cable failure started when an external force caused the failure of several strands of the cable. The most likely candidate for this external force was jet blast from neighboring aircraft while the accident plane was parked overnight. After the first strands failed, the remaining strands could not handle the load from normal flight operations and failed during the accident flight.
