Shortly after takeoff from Kathmandu Airport, while in initial climb, the single engine airplane went out of control and crashed in flames in a cornfield. The aircraft was destroyed by a post crash fire and all five occupants were killed, among them Louise Hillary and Belinda Hillary aged 16, spouse and daughter of the Alpinist Edmund Hillary.
It was determined that the pilot failed to realize that a ground lock pin on one of the ailerons was still in place and not remove prior to departure.
