NTSB narrative
The helicopter was flown to a mountain summit to deliver the bride and groom for a summer solstice wedding. The approach to the summit was made in weather conditions of 10 miles visibility, about 8,000 feet ceiling, and gusty winds. Soon after arrival, deteriorating weather was seen approaching from the northwest. The wedding was performed about 2319 during daylight hours. During the ceremony, it began to snow. The ceremony was concluded quickly due to the weather. A video tape provided by a witness showed the helicopter depart the summit in weather conditions of high winds, sky obscured by blowing snow, and visibility of less than 100 feet. The helicopter collided with terrain less than one-half mile from the departure point. A postaccident inspection of the helicopter disclosed no evidence of mechanical problems, and that the engine was running at the time of the accident.
Probable cause
The pilot's intentional flight into adverse weather conditions, and his failure to maintain altitude/clearance, which resulted in an in-flight collision with terrain. Factors contributing to the accident were the snow and whiteout weather conditions.

- 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, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2002-06-22.
