Incident Overview
At approximately 2,500 feet above ground level, the airplane experienced a complete loss of engine power. The pilot executed a forced landing onto an interstate highway. During the landing flare, the airplane collided with a road sign and a concrete barricade.
Post-Accident Examination
Following the accident, an examination of the airplane revealed evidence of fuel leaking from the fuel line that connects to the fuel pressure gauge. The fuel line was replaced, and an engine test run was conducted afterward, which showed no anomalies.
Fuel Line Identification
Further examination of the removed fuel line indicated that it had been misidentified. The aircraft's data tag specified that the fuel line should be made from an Aeroquip AE701 hose. However, the installed line was made from a nitrile rubber Aeroquip 601 hose.
Conclusion
The investigation determined that the fuel line was not the correct type as specified by the manufacturer. The exact cause of the engine power loss was not explicitly stated in the source.
