Operator's Account
According to the operator, the deicing truck had repositioned itself off the left wing and forward, waiting to deice another aircraft. The left wing walker left his post at the request of the tug driver to scrape snow off the lead-in line with his boot. The aircraft then impacted the deicing truck, dragging it approximately 15 feet. The truck went up on two wheels and was pinned at a 45-degree angle. The tow was stopped and appropriate calls were made.
Environmental Conditions
At the time of the incident, visibility was 1 and 1/2 statute miles, and present weather conditions included light snow and mist.
Operator's Procedures
The operator's procedures in effect at the time stated that the tow tug operator shall ascertain exactly where the aircraft is to be towed and positioned, and know or view the precise route to be taken. Furthermore, the operator shall undertake or continue a towing/pushing procedure only when visual contact with all necessary guidemen is possible. Obstructed vision is the signal to stop and re-establish the necessary guidemen contacts.
