NTSB narrative
The airplane was cleared for the ILS Rwy 27 approach. Radar data indicated the airplane had intercepted the inbound approach course of 271 degrees. The surviving passenger reported he heard the landing gear extension and saw the three landing gear indicator lights illuminate. He reported that he did not hear the airplane malfunction or hear any abnormal sounds. He reported he saw the glow of parking lot lights in the fog out the left rear window. He reported seeing the pilot looking out the left window and then looking to the front of the airplane. The airplane initially impacted two 40 foot pine trees about 800 feet from the wreckage site. The radar data hit was recorded when the airplane was about 1,300 feet msl and about 2.0 nm from the runway. It indicated the airplane's glide path was about 130 feet below the ILS Rwy 27's glide path. The reported weather was winds 120 at 7 knots, visibility 1/2 mile, light rain, mist, indefinite ceiling, 200 foot overcast, 9 degrees C, 29.77. A weather station 14 miles from the accident was reporting the temperature and dew point as 8 degrees C. Ground fog was reported in the area. The airplane did not exhibit any pre-impact anomalies.
Probable cause
the pilot failed to maintain a proper glidepath and obstacle clearance. Factors were the fog and dark night.

- 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.
