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.

Narrative: flight was to report on traffic on the beltway around baltimore when the pilot heard a loud pop. The altimeter light came on and engine oil pressure showed low and the tachometer dropped to zero. The pilot climbed immediately to 2500 feet and flew to a lighted area (night conditions prevailed) where a safe landing could be made. The engine began to lose power. The pilot trimmed to approach speed and landed on route 795 near ownings Mills, MD. There was no damage to the aircraft and no injuries to the occupants. Five quarts of oil were indicated on the engine dipstick. An odor of burned oil was evident emitting from cowling. Removed cowling, inspected exterior to engine. No uncontained failure. An interior failure in the accessory gearbox section partially disabled the oil pump, resulting in the engine seizing.
