Denver International Airport
Aircraft Accident/Incident Report

Denver, Colorado 80249
Monday, December 21, 1998 22:15 MST

NTSB Narrative Summary Released at Completion of Accident

A tug was pushing the aircraft back from the gate when the wheels of the airplane got stuck in snow. The tow bar shear pin, designed to break under excessive loads, snapped in half. The tug struck the airplane, breaking its windshield and causing damage to the aircraft's radome and forward pressure bulkhead. Airport operations personnel are responsible for the removal of snow. According to a ramp manager from the Federal Express Corporation, the snow bank in which the aircraft became mired was 12-16 inches from both the ramp and service road. He stated that the snow should have been plowed but allowed to accrue in that location.

NTSB Probable Cause Narrative

Snow removal not done by other person.
