Probable cause
The pushback tow driver not maintaining visual lookout for the wing walker's visual signal, and the driver not maintaining clearance from the vehicle during the pushback for taxi. Factors to the accident were the standing vehicle behind the airplane, the inadequate group/crew coordination for the pushback, and the lack of guidance in the company's manuals to stop the tow when visual lookout is not maintained.
