NTSB narrative
The airplane sustained minor damage when it struck a deicing truck as it was being towed back to the gate. No injuries occurred. The operator reported, "The de-ice truck had re-positioned itself off of the left wing and forward, waiting to de-ice another aircraft. The left wing walker left his post upon request of the tug driver to scrape the snow off the lead in line with his boot. The aircraft impacted the de-ice 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 made." Visibility was 1 and 1/2 statute mile and present weather was light snow and mist. The operator's procedures current at the time of the accident stated, "3. The tow tug operator will: a. Ascertain exactly where the aircraft is to be towed and positioned, and know (or view) the precise route to be taken. ... d. 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."
Probable cause
The ground tow personnel not maintaining clearance from the de-icing vehicle during the tow back to the gate. Factors were the de-icing vehicle that parked by the airplane's left wing, the ground personnel not following the operator's towing procedures/directives.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
