Analysis

While climbing, there was a heavy smell of fuel. At aprx 150 ft AGL on a precautionary landing, the eng quit. The helicopter impacted hard, collapsing the skids, & the main rotor blades sheared of the tail boom. During an investigation, the fuel hose b-nut (connected to the inlet side of the fuel filter) was found loose & less than finger tight. Moving the fuel hose caused a steady stream of fuel to flow outward from the b-nut. Also, the b-nut on the inlet side of the fuel filter was found to be finger tight & could be backed off with finger force. An annual/300 hour inspection had been performed on 1/10/84, 39 hours prior to the accident.
