Investigator assessment
Analysis narrative
The newly certificated pilot attempted a visual night takeoff with a tailwind. The flight was observed as it climbed out from runway 27 and collided with a tree about 1/4 mile from the end of the sod runway. After colliding with the tree, the airplane continued about 200 plus feet before impacting the ground inverted. Wreckage examination failed to disclose a mechanical malfunction or component failure. However, the carburetor examination revealed that a composite material type float was installed. The airplane was serviced with 30 gallons of automotive fuel. Additionally according to the operator's manual, there is no performance data available to the pilot for a tailwind takeoff.
