NTSB narrative
The aircraft was destroyed when it impacted trees in mountainous terrain at about 7,850 feet msl. The density altitude was calculated to be about 8,400 feet. Examination of the trees and the aircraft wreckage disclosed that the aircraft was in near level flight at the time of initial tree contact. The aircraft gross weight at the time of impact was calculated to be about 3900 pounds; the maximum certificated takeoff weight was 3500 pounds. No mechanical malfunction was found in the airframe or the engine. The owner had personally installed a set of amphibious floats and a three-blade propeller. The installation was not inspected or signed off for return to service, and there was no evidence that the weight and balance had been recomputed.
Probable cause
the pilot's improper planning/decision, which resulted in his failure to maintain sufficient altitude or clearance from mountainous terrain. Factors relating to the accident were: the excessive gross weight of the airplane, the high density altitude, and the high (mountainous) 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1997-10-27.
