NTSB narrative
The dual instructional flight was operated in an area where light rain, fog, and overcast ceilings were present. As the flight proceeded, it entered a hilly area with steady rain, low ceilings, and dense ground fog that extended to above tree height. While maneuvering in that area, the pilots did not maintain sufficient altitude, and the airplane impacted a tree that was likely hard to see because of the reduced visibility. Postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
Probable cause
The flight instructor's decision to continue flight into the area of reduced visibility and the pilots’ subsequent failure to maintain clearance from the hilly terrain while operating in an area of low ceilings, rain, and fog.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2012-03-15.
