NTSB Narrative Summary Released at Completion of Accident

The driver of a deice vehicle, and a ground employee in the bucket of the deice vehicle, were spraying the accident airplane. At the completion of the deice operation, the driver of the deice vehicle began to drive away from the airplane. The ground employee in the bucket of the deice vehicle then observed ice accumulation on the vertical stabilizer. As the driver of the deice vehicle initiated a turn back toward the airplane, the boom of the deice vehicle struck the airplane, resulting in substantial damage to the left elevator.

NTSB Probable Cause Narrative

The deice vehicle driver's failure to maintain clearance from a standing airplane, which resulted in a collision between the deice vehicle and left elevator of the airplane.
