C-GNWI, a Cessna 208 aircraft operated by Northway Aviation, had departed Little Grand Rapids, MB (CZGR) for Winnipeg/St. Andrews, MB (CYAV). Upon touchdown on Runway 18 at CYAV, the brakes failed and the aircraft veered left onto the grass adjacent to the runway. There was no damage as a result of the runway excursion, and no injuries. The runway was closed for approximately 20 minutes while the aircraft was towed to the operator’s hangar.
The operator’s maintenance conducted a subsequent inspection and found that the brake bleeder screws were loose. The brake bleeder screws were tightened, the brake system was checked serviceable and the aircraft was returned to service.
