What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On Saturday January 13th the PIC arrived at Falcon field at approximately 7: 15 am. He proceeded to do a thorough preflight inspection of the airplane and rechecked the weather for the flight he had planned. The PIC started the plane and let it warm up for approximately 15 minutes. After the plane was warm, he got in and contacted Falcon ground control and taxied to the run-up area for runway 4R. During the run-up the engine hesitated and wouldn't go to full throttle. The PIC then rechecked the mixure and didn't notice any RPM drop in either mag. He contacted ground control again and went back to his hangar. Once at the hangar he shut off the power and got out of the plane. He removed the top cowling to inspect for any obvious issues. Having not seen any issues he put the cowling back on and restarted the airplane to see if running the auxiliary fuel pump would make any difference. After not noticing any difference in performance he then shut the plane off and got out to inspect a second time. At that point, he noticed smoke and flames in the bottom cowling of the plane. He got his aircraft fire extinguisher and called 911 at approximately 8:30 am. He used the entire fire extinguisher to knock down the fire and waited for the fire department to show up. After several minutes the fire reignited so he proceeded to look for an additional fire extinguisher in the area. At this point the fire department arrived and put out the fire. After making sure there was no possibility of reiginition he pushed the plane into the hangar and secured it.
