NTSB Narrative Summary Released at Completion of Accident

The Boeing had stopped behind a MD-81 on the yellow lead-in taxi line about 150 feet short of the jetway to await wing-walkers. A wing-walker soon arrived and instructed the Boeing to remain stationary. The MD-81 was then pushed back from its gate into the Boeing. The tug operator for the MD-81 stated that he began to start the pushback once he observed the Boeing pass by. During the pushback the tug operator was "watching the nosewheel and tow bar," and was distracted by other vehicle movements. The tug operator also lost sight of the Boeing at that time.

NTSB Probable Cause Narrative

The inadequate visual lookout by the MD-81's tug driver during the pushback operation.
