What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On Sunday, July 30 2017 the pilot of a Cessna 180 while taxiing to leave Oshkosh felt the aircraft was not handling correctly so he decided to taxi back to parking to investigate. During the taxi process the pilot needed to maintain pressure on the right brake pedal to keep the aircraft straight. The constant pressure on the brake pedal created an excessive amount of heat which caused the fiberglass wheel pant to start on fire. The passenger noticed the fire and they shut down and exited the aircraft and used an on-board extinguisher to subdue the flames. The aircraft sustained damage to the right side brake assembly, wheel, brake lines and wheel pant. The reason for the abnormal taxi process turned out to be a tail wheel that had gone flat. Appropriate repairs were made to the aircraft and they departed approximately 3 hours later without further incident. Neither the pilot nor passenger sustained injuries. The aircraft was being operated under part 91AND VMC conditions prevailed at the time of the incident.
