A Calm Air Avions de Transport Regional ATR-72-212A, registration C-GPBR performing flight MO-771 from Churchill,MB to Winnipeg,MB (Canada) with 58 people on board, was accelerating for takeoff from Churchill still at low speed within the first 100 feet of takeoff roll when the aircraft rolled through a dip in the runway surface. The aircraft subsequently became airborne, upon retracting the gear the nose gear could not be fully retracted and remained in transit. The crew extended the gear again and retracted a second time, however the nose gear again remained in transit. The crew worked the according "Landing Gear Retraction Impossible" checklist, extended the landing gear, assessed their fuel consumption, climbed the aircraft to 16,000 feet and diverted to Thompson,MB (Canada) where the aircraft performed a low approach to have the landing gear inspected from the ground by maintenance personnel of the operator. Maintenance reported that nose gear strut, wheels and tyres were okay, however, the gravel guard attached to the nose gear was damaged. The flight landed in Thompson without further incident.

The Canadian TSB reported the gravel guard was bent backwards and prevented full retraction of the nose gear. The gravel guard was replaced and several gear swings performed before the aircraft was returned to service.
