Incident
Shortly after takeoff, the aircraft experienced a fire. The pilot declared an emergency and received clearance to land on any runway or taxiway. Instead of using a paved surface, the pilot landed in an open field located within the airport boundaries. The aircraft was subsequently destroyed by the fire.
Investigation
Investigators examined the wreckage to determine the fire's origin. They found that the main source of the fire centered around a fuel line. This line extended from a fitting on the back side of the firewall to a fitting on the back of the manifold pressure/fuel pressure (flow) gauge. The aluminum fuel line had melted away due to the fire, but the fittings at both ends remained intact.
Conclusion
The investigation identified the area of origin but did not assign a probable cause. The report noted the fire's source but did not specify a mechanical failure or other contributing factor.
