The cause was the crew's failure to follow the proper procedures for monitoring and controlling airspeed, overreliance on the autothrottle, malfunction of the autothrottle's control system, and failure to carry out a missed approach. Although substantially damaged, the aircraft was repaired and returned to service. [17] 27 February 1987
