NTSB narrative
The newly certificated private pilot and his wife took the pilot's father and sister for an airplane ride. Hunters heard an airplane flying in the valley, then heard a loud noise. Searchers were guided to the wreckage by the airplane's emergency locator transmitter. The airplane had collided with a large spruce tree while in a steep left bank, 60 feet above the ground, then slid 10 feet down and became entangled in its branches about 50 feet above the ground. The pilot had received his pilot's license 6 days earlier. He had logged 66.5 total hours, of which 4.6 were in airplane make and model. The pilot had also received 4.1 hours of dual instruction in 'mountain course/high altitude' flying. It was calculated that at the time of the accident, the airplane exceeded its aft c.g. limit slightly. Performance charts indicate that under the prevailing conditions, the airplane was capable of climbing about 240 feet per minute.
Probable cause
The pilot's improper inflight planning/decision. Factors were a reduction in the airplane's climb and turn capabilities, the aft c.g. limit being exceeded, and the pilot's lack of familiarity with the geographic area and his lack of experience in the airplane make and model.

- 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.
