Initial climb

Probable cause

Improper installation of a fuel line by unknown personnel, which resulted in a total loss of engine power during initial climb due to fuel starvation.

NTSB narrative

Shortly after takeoff for a local personal flight, about 300 ft above ground level, the private pilot of the airplane smelled fuel. The engine lost all power shortly thereafter, and the airplane descended, collided with trees, and then impacted terrain. An examination of the airplane revealed that the fuel line between the electric fuel pumps and the engine driven pump had a loose connection at the fuel shut-off lever. During a postaccident engine run, when the electric fuel pumps were on and delivering fuel under pressure to the engine, the loose connection did not affect engine operation. However, when the electric fuel pumps were shut off, the engine-driven fuel pump suctioned air through the loose fuel line connection resulting in fuel starvation and loss of engine power. It is likely that the engine lost power during the accident flight when the commercial pilot turned off the electric fuel pumps after takeoff. The airplane's most recent annual inspection was completed about 7 months before the accident. The investigation could not determine if the fuel line had been installed before or after the annual inspection because there was no logbook entry regarding installation of the fuel line.
