Analysis

The aircraft was being used on an external load operation. On his fourth load, the pilot was to transport a 1190 lb electric pump and fan from the back of a pickup truck. While preparing to lift the load, the pilot was not satisfied with its position. He released the external load line from the bottom of the helicopter, moved the helicopter to the right, and landed near the pickup truck. Just prior to landing, the main rotor blades struck the load and knocked it out of the truck. The ground hookup person received minor injuries from flying debris.
