NTSB investigators used data provided by various sources and may not have traveled in support of this investigation to prepare this aircraft incident report.

During initial pushback, the trainee operating the ground support vehicle, turned the aircraft in the wrong direction, at which time, the supervisor took over control of the vehicle. During the supervisor's attempt to turn the aircraft around, the nose wheels rolled out of the vehicle's wheel cradle and up onto the ground support vehicle. An employee reported she overheard one of the flight crewmembers report to dispatch that the ground personnel was making a sharp turn and the crewmember thought the airplane was going to be pushed back into another airplane. The company which provided the ground support personnel stated the push back operation should have come to a stop and communication should have been conducted between the flight crew and ground crew to resolve all concerns about safe maneuvers.

The National Transportation Safety Board determines the probable cause(s) of this incident to be:

The improper procedures conducted by the ground personnel and the flight crew's failure to coordinate procedures with the ground personnel during push back operation which resulted in the collision between the ground support vehicle and the airplane. A contributing factor was the inadequate communication between the flight crew and ground crew during the push back operation.
