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.

?At approximately 1317 local, the pilot departed Unalakleet Airport for st. michael on an IFR flight plan. The pilot landed there without incident, loaded passengers on board, and then departed back for Unalakleet at 1409. Upon reaching 5000 ft headed to vusuy, the pilot was getting ready to perform the turbine trend for the day when he noticed that oil temperature was out of limits on the hot side, by 10 celsius. After doing a quick scan, he found that all other engine parameters were normal. He notified ATC, canceled IFR and declared an emergency. He stayed on their frequency while monitoring CTAF. At the time there was a broken cloud layer with multiple areas of scattered up ahead. He began a descent, to get to more solid VMC through one of the holes, but also in a bid to cool the engine. It did work, as the oil temp did slide to just above redline. He continued on to Unalakleet and landed without incident. Upon exiting the aircraft, he discovered what was left of the cowl plugs, the intake was gone, and the oil cooler cover was right where it had been left the night before. He had missed them on final walk-around.
