Aircraft Accident/Incident Report

Sequim, Washington 98382

NTSB Narrative Summary Released at Completion of Accident

The public-use helicopter was being operated in a joint effort search for a missing hiker outside of the park. The single pilot had landed at a remote landing zone in mountainous terrain to retrieve seven search and rescue personnel plus a dog. The pilot advised the SAR personnel to load quick, as he had no intentions of spending the night there. The pilot held up five fingers to ground personnel, who assumed that meant to wait 5 minutes for the obscuration to clear. However, in less than that time, the helicopter performed a vertical takeoff in the obscuration. According to the remaining SAR personnel, they lost sight of the helicopter about 50 feet agl. They continued to hear the helicopter to the time of a collision sound, followed by the sound of an avalanche. The remaining SAR personnel departed the landing zone for cover.

NTSB Probable Cause Narrative

the pilot's intentional flight into known adverse weather conditions in mountainous terrain.
