Landing and Accident Sequence
A pilot was landing on a 2,000-foot-long private airstrip. According to a witness, the airplane landed on the last third of the runway. From the initial touchdown point, the airplane rolled 140 feet, after which heavy braking and skid marks were observed on the runway. The airplane then traveled another 460 feet before coming to rest off the left side of the runway.
Pilot Report and Runway Conditions
The pilot reported that during the landing roll, he encountered rough runway conditions that remained from recent maintenance. When the airplane reached a smoother and harder surface, the pilot applied the brakes, and the airplane ground looped to the left. The airport/facility directory notes that the turf/gravel runway surface is muddy and washed, 6 to 12 inches deep, and is not maintained.
Aircraft Damage
The right main landing gear was folded aft at the gear leg attach point to the fuselage. The airplane also sustained damage to the inboard end of the right wing aft spar and the right wing tip.
