The pilot attempted a landing on runway 30 (2,394 feet by 48 feet), which was slush-covered. During the landing rollout, the airplane "swerved hard right" and into a snowbank, where it nosed over. The airplane sustained substantial damage, which included damage to the wing ribs, wing trailing edge, and rudder. A weather reporting station about 9 miles from the accident site recorded variable winds at 4 knots at the time of the accident. Examination of the airplane revealed that the brake pin lubrication had dried out and the right brake caliper would not release. ## Factual narrative The pilot was returning to the departure airport after having flown for approximately two hours at various cruise altitudes.
