NTSB narrative
The pilot and two passengers departed for a remote area on an on-demand charter flight in a float-equipped airplane. An emergency locator transmitter signal was heard in the area of the intended destination about 55 minutes after departure. The flight was reported overdue and search personnel located the wreckage at an elevation of about 2,850 feet in mountainous terrain about 2 and 1/2 hours after departure. The airplane collided with terrain below the top of a steep ridge. Search personnel reported the weather conditions in the area included low ceilings. The conditions deteriorated during subsequent rescue operations. The area forecast included an AIRMET for marginal VFR conditions with mountain obscuration due to clouds and precipitation.
Probable cause
continued flight by the pilot into adverse weather condition, and his failure to maintain adequate altitude/clearance from mountainous terrain. Factors related to the accident were the high/mountainous terrain, and weather conditions that included low ceilings.

- 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.
