What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23)The pilot, who owned the aircraft and had not flown it, had been taxing it for familiarization purposes. He was also not familiar with the privately owned airstrip (unlisted). After a high speed taxi run the pilot found himself on the down hill slope toward the end of the sod runway. Braking was not very effective, and in an attempt to turn the aircraft, it slid sideways, collapsing the landing gear, before striking a brush pile.
