NTSB narrative
The pilot received three weather briefings from a flight service station prior to departure. The briefings included forecasts of thunderstorm activity along the planned route of flight, and in the area of the departure airport. The pilot was asked by the weather briefer if the airplane was equipped with weather radar. The pilot stated that he had a stormscope and weather radar. He departed the runway with a 15-20 knot tailwind, did not follow the published instrument departure procedure, and flew south toward mountainous terrain. The wreckage was located about 200 feet from the summit, on the south side of the mountain. Witnesses at the airport and in the vicinity of the accident site report hearing thunder about the time of the accident. Additionally, weather imageries and surface observations confirmed areas of heavy precipitation south of the airport, in the vicinity of the accident site, at the time of the accident. The pilot made four brief transmissions to Air Traffic Control, but was never in radar contact.
Probable cause
The pilot's inadequate in-flight planning/decision, his failure to follow the published instrument departure procedure for the particular runway, and his continued flight into known adverse weather. A factor was thunderstorms.

- 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.
