Analysis

The aircraft's landing gear collapsed after the plane went off the right side of runway 23 during takeoff. Reportedly, the aircraft drifted to the right of centerline on a fairly constant arc until contacting a snow berm at a taxiway intersection. An investigation revealed that the takeoff was being conducted at night with a partially obscured windshield. Visibility was one mile with fog and falling snow, and the wind was from 150 degrees at 11 knots. The runway was covered with about 1/4 inch of snow. The copilot's duties required him to scan 'inside' the cockpit, while he 'fine tuned' the power settings and checked engine instruments during the takeoff roll. No pre-accident part failure or malfunction of the aircraft was found during the investigation.
