The airplane departed the left side of the runway, impacted airport signage and other obstructions, and came to rest 450 feet to the left of the centerline. The airplane was substantially damaged when the landing gear collapsed and the top skin of the right wing partially separated. The winds reported at the time of the accident were from 30 degrees to the right of the runway alignment at 13 knots.
