Category:Accident
Location:Northwest of Morrisville, NY -   United States of America
Phase: En route
Nature:Private
Departure airport:Hamilton, NY (VGC)
Destination airport:Hamilton, NY (VGC)
Investigating agency: NTSB
Narrative:
The private pilot rented the airplane for a local pleasure flight and departed the airport with full fuel tanks. The airplane had been flying for about 30 minutes and then began a series of turns with its altitude fluctuating between 1,900 and 2,100 ft mean sea level (about 600 to 800 ft above ground level). About that time, one witness reported the engine began "spitting and sputtering" and experienced a total loss of power. Other witnesses reported that the engine stopped, restarted, and then lost power again. The airplane subsequently pitched nose down and entered a spin before ground impact, which is indicative of an aerodynamic stall. Postaccident examination of the airframe and engine did not reveal any evidence of preimpact malfunctions; however, damage to the engine and its associated components precluded a functional check of the engine. Additionally, there were no anomalies noted or reported with the fuel source that would have resulted in a loss of engine power. Although the environmental conditions were favorable for serious carburetor icing at glide power, it is likely the pilot was operating the airplane in cruise flight before the reported engine fluctuations.
Probable Cause: The pilot's failure to maintain airspeed and her exceedance of the airplane's critical angle-of-attack, which led to an aerodynamic stall, following a total loss of engine power for reasons that could not be determined because postaccident examination of the airframe and engine did not reveal any anomalies that would have precluded normal operation.
