What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
A Cessna 150 aircraft intended for a training flight encountered an engine fire on the ground before flight. The student pilot stated he primed the engine and after numerous attempts observed black smoke and then proceeded to abandon the aircraft. During this time the engine started ignition, throttles and fuel all engaged began to accel forward onto the parking ramp where other aircraft wer moored. He also stated that once back in and gaining control applied the brakes, turning the aircraft right but, consequently struck a Piper (PA-28) parked nearby causing substantial damage to the aircraft and minor damage to the Cessna. During the inspection the evidence is consistent with a carburetor fire damaging associated lines, with slight burn marks on the lower engine cowling. There was also damage to the right wing at the leading edge spar line & slight damage to the lower pilot door both minor.
