Aircraft Accident/Incident Report
Madison, Georgia 30650

NTSB Narrative Summary Released at Completion of Accident
Before takeoff, a witness observed the pilot performing a preflight inspection, during which the pilot appeared to check the fuel system for contaminants. The airplane subsequently departed and was observed to climb to between 150 and 200 feet above ground level before a witness heard a loud “bang” and noted black smoke trailing from the airplane. Additionally, several witnesses reported that the engine was “running rough.” The airplane continued to fly about the same altitude with the engine sputtering and running rough, emitting puffs of black smoke every 1 to 2 seconds. Several witnesses indicated that before the airplane flew past the departure end of the runway, it stalled, entered a spin, and impacted terrain.
Postaccident examination of the engine revealed crankshaft, camshaft and valve train continuity. Examination of the ignition system revealed no discrepancies. The carburetor was removed and bench tested, which revealed that it produced a richer-than-specified fuel/air mixture at several throttle positions, including full throttle, which would be used for takeoff. However, it is unlikely that the overly rich fuel/air mixture caused the symptoms reported by the witnesses. Although weather conditions at the time of the accident were conducive to serious carburetor icing at glide power, the airplane was not operating at glide power during the accident takeoff. The investigation was unable to determine the cause of the power loss.
NTSB Probable Cause Narrative
The pilot’s failure to maintain airspeed following a loss of engine power during takeoff for reasons that could not be determined because postaccident examination did not reveal any anomalies that would have precluded normal operation, and the airplane’s subsequent aerodynamic stall.
