NTSB narrative
According to the flight instructor and student pilot, while maneuvering to land, the accident airplane encountered wake turbulence from a preceding C-130 airplane. The accident airplane then began an uncommanded pitch, roll, and descent that could not be arrested prior to an impact with terrain. A review of radar data revealed that the flight path of the accident airplane was in an area favorable for a wake vortex encounter. No anomalies were reported by the flight instructor and student pilot or noted during the postaccident examination of the airframe and engine.
Probable cause
The student pilot's inability to maintain aircraft control due to an encounter with wake turbulence from a preceding larger aircraft. Contributing to the accident was the instructor pilot's failure to intervene.

- 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.
