Analysis

The acft collided with a truck while attempting to land on the loading pool of the truck being used for refueling purposes. The pilot of the helicopter stated that when about 6 inches from touchdown he felt something funny and since the refueling man was standing of the platform close to the helicopter he elected to land on the ground. In maneuvering the acft the tail boom hit the truck bed, the pilot lost control and the acft rolled over on its right side. There was no fire and only one minor injury.
