What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot reports that he was familiar with this unimproved desert landing/camping area and had landed there before. On the accident flight in calm winds he had one passenger in the right front seat who he may or may not have given a briefing to regarding keeping clear of the aircraft flight controls. (He cannot recall.) After touchdown the aircraft made a sudden "veering" to the right that he was unable to counter with rudder input and braking, and the aircraft groundlooped and ended up inverted.
