A witness first heard the airplane make a backfiring sound. The witness then observed the airplane coming out of the north, heading south toward his house at low altitude. When the airplane was over his house, it turned to the southwest. The witness saw the airplane initiate a 'fast' left turn and then go straight down into a corn field. Another witness said the airplane went over their yard at about 500 to 600 feet above the ground and headed south to southwest rocking its wings slightly. The witness saw the airplane initiate a right turn to the west and said that the engine sound changed from banging to a sputter. The witness said the airplane continued its turn to the north and started come back toward them. A third witness said he saw the airplane go straight down into the corn field. He also said that the airplane 'got about half a turn,' toward the east before it hit. Examination of the wreckage revealed that the engine's #2 cylinder exhaust valve was stuck open.
Probable Cause: a loss of power due to the engine's #2 cylinder exhaust valve stuck open, and the pilot's failure to maintain airspeed.
