NTSB narrative
Before beginning the cross-county flight under visual flight rules (VFR), the pilot received a weather briefing that reported VFR conditions at the departure and destination airports but included an airmen's meteorological information notice for instrument flight rules (IFR) conditions along the route of flight. About 8 minutes after departure, recorded radar data showed the airplane's altitude varying between 321 and 635 ft above ground level (agl) for about 1.5 minutes before the impact. Until about 30 seconds before impact, the airplane was tracking south on course along a valley, but it then began to deviate west toward rising terrain. The airplane then began a slow, descending right turn. The last recorded radar target showed the airplane about 0.2 miles from the accident site, at an altitude of about 410 ft agl.
A postaccident examination of the airframe and engine revealed no evidence of preimpact mechanical malfunctions or failures that would have precluded normal operation. A review of weather observations and satellite imagery indicated that IFR conditions prevailed in the vicinity of the accident site due to low clouds and restricted visibility. It is likely that the pilot was varying his altitude to remain clear of the clouds and subsequently entered an area where continued flight on course was not possible and initiated a right turn. During the turn, the airplane collided with rising terrain.
Probable cause
The pilot’s continued visual flight into instrument flight rules conditions, which resulted in his failure to maintain sufficient clearance from rising terrain.

- 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, coordinates. 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.
