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.
Powerplant failure resulted in an off-airport landing with no apparent damage to the aircraft, except within the engine compartment. Inspection of the engine revealed a bent pushrod and associated tube, as well as breakage and detachment of the carburetor heat box duct flange. The operator's mechanic stated that the number four exhaust valve had stuck, resulting in the damage and nearly complete absence of power.
