Narrative:

Following de-icing of the aircraft, while the aircraft was parked with engines shutdown, the de-icing unit hit the horizontal stabilizer on the right side of the aircraft when the driver was pulling away. The unit hit the aircraft forcefully, throwing the driver out of the vehicle. The vehicle continued to ram into the stabilizer for approximately 10 seconds until the driver was able to climb back in and regain control. Substantial damage was sustained on the outer portion of the right horizontal stabilizer. The flight was cancelled and the passengers deplaned. Maintenance personnel were flown in to inspect and repair the aircraft. Note: the de-icing was accomplished by only one man, contributing to the likelihood of a mistake.
