Witness Observations
Multiple witnesses reported observing a Champion 7GCBC flying at low altitude and maneuvering. According to the witnesses, while the airplane was maneuvering, its nose dropped and the airplane subsequently descended into a wooded area.
Examination Findings
Examination of the accident airplane revealed that the tachometer indicated 2,500 rpm. Several pieces of wood with smooth angular cuts were found along the debris trail leading to the accident site; the largest piece of cut wood measured about 5 inches across. Flight control continuity was confirmed; however, the intensity of the fire melted many metal components, and some items could not be inspected.
Weight and Balance
Based on an estimated weight and balance calculation, the airplane could carry 11 gallons of gasoline and remain under the maximum allowable takeoff weight. With full fuel, it would be 161 pounds over its maximum allowable takeoff weight. The actual amount of fuel onboard at takeoff and at the time of the accident was not determined.
