From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

The pilot leaned the engine before takeoff, but as the aircraft reached about 50 feet AGL, the engine lost power. He switched tanks, enriched the mixture, pumped the throttle, and attempted to restart the engine. The engine started, but it ran for only a few seconds before quitting again. When his second attempted restrat was unsuccessful, he excuted a forced landing. During the forced landing, the airplane hit a log and was damaged. The pilot said he could have induced the problem by over leaning the engine. He also said he could have restricted the fuel flow when he inadvertently moved the fuel selector beyond the tank detent. The aircraft was fueled with a mixture of aviation fuel and auto gas, but it did not have an STC for auto gas. The aircraft had not had an annual inspeciton withing the previous 12 months, and the pilots medical certificate had expired.

As the FAA filed it

THE PILOT LEANED THE ENGINE BEFORE TAKEOFF, BUT AS THE AIRCRAFT REACHED ABOUT 50 FEET AGL, THE ENGINE LOST POWER. HE SWITCHED TANKS, ENRICHED THE MIXTURE, PUMPED THE THROTTLE, AND ATTEMPTED TO RESTART THE ENGINE. THE ENGINE STARTED, BUT IT RAN FOR ONLY A FEW SECONDS BEFORE QUITTING AGAIN. WHEN HIS SECOND ATTEMPTED RESTRAT WAS UNSUCCESSFUL, HE EXCUTED A FORCED LANDING. DURING THE FORCED LANDING, THE AIRPLANE HIT A LOG AND WAS DAMAGED. THE PILOT SAID HE COULD HAVE INDUCED THE PROBLEM BY OVER LEANING THE ENGINE. HE ALSO SAID HE COULD HAVE RESTRICTED THE FUEL FLOW WHEN HE INADVERTENTLY MOVED THE FUEL SELECTOR BEYOND THE TANK DETENT. THE AIRCRAFT WAS FUELED WITH A MIXTURE OF AVIATION FUEL AND AUTO GAS, BUT IT DID NOT HAVE AN STC FOR AUTO GAS.
