Analysis

The acft with 4 occupants on board was being used on a sight-seeing flt to mauna loa volcano. The plt was in radio contact with hilo tower from 1503 to 1506 HST. He indicated concern about the clouds & decided not to proceed to the volcano. When the acft failed to return, a search was initiated, but it was hampered by rains. On 4/12/84, the wreckage was found on the north slope of mauna kea volcano. An exam revealed the acft had crashed (hdg 320)on downward sloping terrain while in a steep descent. There was virtually no movement after impact. The acft was accordioned, 10 ft from the bulkhead to the empennage. No evidence of an in-flt structural failure or power failure were found. The acft clock had stopped at 3:10.
