During initial climb between 100 and 200 feet above ground level, the airplane's engine lost all power due to fuel starvation. The pilot made a forced landing in a marsh about 1/4-mile beyond the runway's departure end. After the airplane came to rest upside down in the 2- to 4-foot-deep marsh, the pilot extricated himself and waded to the shore. The pilot had refueled his airplane just before takeoff. During takeoff, full engine power was initially developed with the fuel selector positioned to the "Both" tanks position. Following the accident when the airplane was examined, no evidence of any preimpact mechanical malfunction was noted. The engine's electric fuel pump switch was observed in the "OFF" position. The pump switch was required to be "ON" during takeoff. During the initial climb, the engine driven fuel pump likely had not pumped sufficient fuel to the engine to maintain power, which resulted in fuel starvation.
Probable Cause: A total loss of engine power during initial climb due to fuel starvation, which was caused by the pilot's failure to turn on the electric boost pump and an undetermined failure of the engine driven pump to supply sufficient fuel to the carburetor.
