NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

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.
