The NTSB's narrative final · quoted from the NTSB record
The pilot of the aero-logging helicopter had lowered a multiple-log load onto the landing site, hit the release switch to release the two choker cables, and then began to move away from the area. One of the choker lines momentarily failed to release, resulting in one end of one of the logs lifting into the air and then falling back to the ground. One of the ground crew members entered the landing area after the logs were initially lowered to the ground, but prior to the release of the second cable. When the end of the log lifted into the air and fell back to the ground, it fell on the crew member, inflicting fatal injuries. It was the opinion of some of the other crew members that the victim never noticed that the second cable had not yet released or that the end of the log was being lifted back into the air. According to Washington Administrative Code, Chapter 296-54, 'Logs shall be laid on the ground and the helicopter will be completely free of the choker()s) before workers approach the logs.'
