Incident Overview
A pilot reported that the engine lost partial power during the climbout after departure. The pilot attempted to return to the airport, but during the turn, the engine lost all power. A forced landing was performed in a field.
Engine Examination
Under the supervision of an FAA Inspector, the engine was examined. After two failed attempts to start the engine, a carburetor float was freed. Subsequently, the engine ran to rated power. Further examination of the carburetor revealed that it flowed within operational limits.
Departure Conditions
According to witnesses, the airplane departed with a 9-knot tailwind. The airplane's takeoff weight was estimated to be about 20 pounds over the maximum takeoff weight. The weight calculations did not include baggage that was no longer available to be weighed.
Conclusion
The incident involved a partial power loss followed by total power loss, with the engine later operating normally after the carburetor float was freed. The departure conditions included a tailwind and an estimated weight slightly above the maximum.
