United States of America
|Phase:|| Take off|
According to the pilot, some electrical lines and the main fuel line were routed through the same area and held in place by a common clamp. An electrical line shorted and burned a hole in the fuel line.
The pilot stated that the routing of the lines together was pointed out to him by a mechanic and he was told this was a potentially unsafe installation. The pilot said that had he followed the mechanic's advice and rerouted the lines the accident would not have happened. In addition, the pilot stated he had to perform a down wind autorotation from about 50 feet and landed hard on the down slope of a levy.
PROBABLE CAUSE:A TOTAL LOSS OF POWER DUE TO A LEAK IN THE MAIN FUEL LINE WHICH OCCURRED AS A RESULT OF AN ELECTRICAL SHORT WHICH BURNED A HOLE IN THE FUEL LINE. FACTORS WERE A FAILURE BY THE PILOT TO PERFORM RECOMMENDED MAINTENANCE AND THE LACK OF SUITABLE TERRAIN FOR A FORCED LANDING.
