During the pre-departure preparations, one end of a towbar was connected to the nose landing gear of a Boeing 737 aircraft and a pushback tractor was positioned approximately one metre from the towbar's opposite end. A ground engineer subsequently started the tractor with the intention of hooking up to the towbar. When the engineer released the handbrake, the tractor lurched forward and struck the towbar. The force of the impact fractured the aircraft nose landing gear drag brace. The nose landing gear assembly then pivoted back under the aircraft, becoming jammed between the towbar and the aircraft fuselage.

Probable Cause:

The investigation was unable to determine the reason for the sudden movement of the pushback tractor.
