The Aérospatiale AS 332L1 (registered JA9965, operated by Nakanihon Air Service) was lifting a box-shaped work shed from the Mt. Shaka Loading Site in Kitahira, Otsu City, Shiga Prefecture. While attempting to lift the load, it struck and seriously injured a ground worker.
PROBABLE CAUSES
It is highly probable that as the helicopter was about to lift the shed, a sling leg was caught by the eaves, bringing the shed into a partially lifted state, and that the shed moved in this state to come into contact with the handler, who had dashed to the area, resulting in the handler’s fall on the valley side of the area and subsequent injury.
Regarding the situation that the shed, which had attained a partially lifted state, came into contact with the handler, it is probable that this was caused by the fact that there was a difference between the crew members and the ground operators regarding recognition of the sling work implementation method. It is probable that this difference was caused by the fact that in the safety education conducted in advance by the aviation company, the ground operators did not have a solid understanding of issues that were important for securing safety
