What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) While enroute on a part 14 CFR 135 on demand flight with five passengers onboard, approximately one hour out from a scheduled fuel stop in Omaha, Nebraska, a passenger complained to the pilot that the toilet would not flush. The pilot called the company and was directed to reset a tripped circuit breaker. The breaker immediately tripped and the pilot was told to leave it out until they arrive on Omaha where they would have repairs made or defer it. After the aircraft was refueled and ground power was connected, approximately fifteen minutes later, the pilot observed smoke coming from around the lavatory window. The pilot retrieved the cockpit fire extinguisher and returned to the lav. At this time there were flames exiting the headliner. The pilot emptied the extinguisher and exited the aircraft. The fire was finally extinguished by the fire department. An 18 inch by 24 inch hole was burned through the left side of the fuselage between frame 22 and 24 above the lavatory window. Damage was substantial and there were no injuries.
