Dansville, New York 14437
Saturday, September 10, 1994 13:15 EDT
NTSB Narrative Summary Released at Completion of Accident
THE PILOT ELECTED TO EXTEND THE DOWNWIND LEG DUE TO POWERED AIRCRAFT TRAFFIC AHEAD ON THE APPROACH. THE POWERED AIRCRAFT SAW THE GLIDER AND DISCONTINUED THE APPROACH, ALLOWING THE GLIDER A CLEAR PATH TO THE RUNWAY. THE GLIDER PILOT ELECTED NOT TO EMPLOY SPOILERS BECAUSE THE DISTANCE TO THE RUNWAY WAS TOO FAR. ACCORDING TO THE PILOT 'WITHIN SECONDS MY ALTITUDE AND SPEED WAS REDUCED.' HE REACTED BY PUSHING FORWARD ON THE CONTROL STICK, TO GAIN SPEED, BUT THE GLIDER DID NOT RESPOND. THE PILOT WROTE HE 'WAS BEING FORCED DOWN FROM ABOVE AT A RAPID RATE' CAUSING HIM TO BELIEVE HE WAS IN A 'VIOLENT' DOWN DRAFT. THE GLIDER STRUCK A TREE WITH THE LEFT WING ABOUT 400 FEET SHORT OF THE RUNWAY.
NTSB Probable Cause Narrative
THE PILOT ALLOWED THE SPEED OF THE GLIDER TO GET TO LOW ON FINAL APPROACH WHICH RESULTED IN A RAPID DESCENT, SUBSEQUENT UNDERSHOOT OF THE RUNWAY, AND IMPACT WITH A TREE. A FACTOR IN THIS ACCIDENT WAS A DOWNDRAFT CONDITION.
