NTSB narrative
An airplane, believed to be the float-equipped accident airplane, was observed by two witnesses, when it flew near their remote hunting camp. They related the airplane was flying very low over the nearby Etivluk River. The witnesses said they wondered why anyone would be flying in such 'horrendous' weather. They estimated the wind velocity was 80 miles per hour, with higher gusts. The airplane was discovered after it had crashed inverted on a gravel bar in the Nigu River. On-site examination disclosed that pieces of the upper left wing skin had separated from the airplane; the pieces were located approximately 3/4 mile from the main wreckage. The left aileron and flap were bent upward and rearward. The wing struts remained attached to their respective wing attach points. The upper 18 inches of the left wing struts were curled upward toward the airplane's cabin. The airplane was destroyed by postimpact fire.
Probable cause
the pilot's inadequate weather evaluation and resultant flight into adverse weather conditions. Factors associated with the accident were: high winds and terrain induced turbulence.

- 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 1996-08-24.
