It started on runway centerline and traveled to the end, gradually traveling toward the left edge. From the end of the runway hardtop, the skid mark went through the grass, across a 14 inch wide trench, and terminated at the dirt pile. Examination of N4668J was conducted on 11-29-79 in a hangar at (X) Airport where the aircraft had been moved to protect it from vandalism.

'The left wing was deformed, buckled and wrinkled at the rear spar, starting at the wing root and traveling outboard for approximately 7 feet. Rivets were and skin wrinkled on the left wing lower side at the area behind the left main gear well. The right main landing gear disc brake assembly had failed at the area were it is welded to the brake disc housing. This area was badly corroded to the point where the metal in this area is paper thin. Both propeller tips were bent 90deg. and one bend had a crack 1-1/2 inches long. Nose wheel gear was torn and bent. N4668J had sustained major structural damage to the left wing.
