What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot landed at Williston airport and reported that the landing gear collapsed after landing just before he tried to turn off the runway. The landing gear was still in the uplocked position in the post incident pictures provided to the FAA. The video footage provided by the Williston airport does not appear to show any collapse to back up the pilot's claim. The video appears to show the plane sliding down the runway. Post accident tests were done with the aircraft at the maintenance shop in Williston and the landing gear and warning horn functioned normally with no anomalies.
