AERONCA 7AC
The pilot of the Aeronca 7AC stated that during the engine run-up for departure, he observed that the right magneto "failed." The pilot taxied the airplane back to the ramp, and a mechanic serviced the right magneto. The pilot then performed another engine run-up, which was satisfactory, and the airplane departed on runway 17. About 50 feet above ground level, the engine lost partial power. The pilot attempted a left turn back toward the airport, as there were trees in front of him. During the turn, the airplane stalled and impacted terrain. Examination of the wreckage revealed an inoperative left magneto.
