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.

(-23) During cruise at 10,500 ft, the engine started surging with RPM drops of 1000-1500 from setting. Pilot checked primer, carb heat, magnetos, mixture, and fuel selector with no relief. Pilot declared emergency. At 6,000 feet the engine ran smoothly through landing. The aircraft was inspected and test flown with no defects noted. Prior to takeoff AWOS info gave a 20 degree split. It was a very clear, low humidity day. The OAT was 28 degrees. Carburetor ice is possible cause.
