Narrative:
A mechanic had parked a ground support van outside the baggage area under Gate 26, and exited the van. When he returned to the van several minutes later, it had rolled backwards and impacted a parked aircraft. Examination of the van revealed the gearshift lever was faulty, and when the 'park' detent was selected, the van was actually in 'reverse'. The operator's fleet of ground support vehicles was examined for additional faulty gearshift levers, and one vehicle was identified and removed from service. Examination of the airplane revealed a 10-inch hole, with a larger dented area in the fuselage pressure bulkhead, located on the left side of the airplane, midway between the left engine and the L1 door.

Probable Cause: The collision of a ground support vehicle with a parked aircraft, due to the faulty gearshift lever on the ground support vehicle.
