NTSB narrative
The airplane was in cruise flight about 5,000 feet mean sea level (msl) in instrument meteorological conditions when the pilot declared an emergency and reported a loss of "fuel pressure" and engine power. The air traffic controller vectored the airplane toward the nearest airport, and, during the descent and when the airplane was about 6 miles from the airport, the pilot reported that smoke was in the cockpit and that the engine was "barely" producing power. No further transmissions were received from the pilot. The airplane collided with flat, wooded terrain and was significantly damaged by postcrash fire.
Data downloaded from the primary and multifunction cockpit displays indicate that the engine began steadily losing oil pressure during the airplane's initial climb until it leveled off at a cruise altitude of 5,000 feet msl. Data suggest that, at that time, the pilot leaned the fuel mixture for cruise flight. Although the pilot could have detected the decreasing oil pressure at that time, he did not report a loss of fuel pressure and engine power to the air traffic controller until about 6 minutes later. Data also indicate that there were multiple additional indications and cues of a loss of engine oil pressure in the cockpit but that the pilot did not respond to these in a timely manner. The operations manual indicates that the pilot should land as soon as possible if the engine oil pressure drops and then to prepare for a loss of engine power and an emergency landing. The pilot's delayed recognition of the drop in engine oil pressure was likely the result of a breakdown in her instrument scan, specifically, her systems monitoring during the climb and initial cruise phases of flight, during which time, her attention was likely directed at airplane control, power management, and navigation. The reason for the loss of engine oil pressure could not be determined during postaccident examinations due to postcrash fire damage.
Probable cause
The pilot's failure to detect multiple indications and cues in the cockpit of the steady loss of engine oil pressure, which resulted in a catastrophic engine failure over terrain unsuitable for landing. Also causal was the loss of internal engine lubrication for reasons that could not be determined during postaccident examinations due to postcrash fire damage.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
