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.

Engine quit on climbout. Hit wires the rocks. Metal in oil. Oil pump siezed. Faulty overhaul 162 hrs prior. (.4) during the initial takeoff climb, the pilot reduced power and the rpm's dropped to zero, but there was no sound change in the engine. The pilot attempted to return to the airport for a precautionary landing. During the turn back to the airport, the engine began to run rough. The pilot was unable to make the runway and made an off-airport emergency landing and collided with ground obstructions. A post-accident investigation revealed an oil starvation failure of the engine. The oil pump's drive gear shaft had failed in torsional overload. Examination of the oil pump's driven gear revealed that the required bronze bushings between it and the driven gear shaft were absent. It was noted that the engine was overhauled 162 hours prior to the accident. During the engine overhaul, the oil pump was sent out for overhaul and was returned to the owner as a disassembled unit. The owner/pilot, who was not a certified a & p mechanic, reassembled the oil pump and reinstalled it on the airplane. A certified a & p mechanic reported that he did sign the logbook to this affect, bu (-23) see attached copy of program tracking & reporting subsystem (ptrs) comment section transmittalprivacy data omitted made by the FAA iic and downloaded into the national data base. It describes, in chronological order, the sequence of investigative steps taken so FAR in this accident report.(no narrative attached).
