An aircraft lost engine power at 400 feet during initial climb, leading to a forced landing on a public road. The wing struck a cattle guard post, and the aircraft slid off the road. Investigation found the fuel pump vapor return jet clogged with rubber debris from a new fuel hose installed at the last annual inspection.

Accident Sequence

During the initial climb after takeoff, at approximately 400 feet above ground level, the aircraft experienced a loss of engine power. The pilot initiated an emergency forced landing on a public road. As the aircraft rolled along the road during the landing ground roll, the wing impacted the post of a narrow cattle guard that spanned the road. The aircraft then slid off the road and came to a stop.

Investigation Findings

After the accident, the engine was tested and quit again while running. An examination of the engine fuel system revealed that the engine fuel pump vapor return jet was plugged with a small piece of black, crescent-shaped rubber material. A new fuel hose to the engine fuel pump, made of black rubber material, had been installed during the last annual inspection. The source of the rubber debris was determined to be from this newly installed hose.
