What happened
The glider touched down approximately 150 feet beyond the end of the runway. This incident occurred during the pilot's first solo flight in this specific aircraft type. While on final approach at a speed of 55 mph, the pilot observed a rapid decrease in altitude. In response to the sinking airspeed and descent rate, he attempted to adjust the spoiler position to manage the glide path.
The pilot reported that the mechanical resistance of the spoilers was unusually stiff. He stated that this stiffness misled him regarding the actual position of the flight controls, causing a delay or error in his compensation efforts. The combination of the rapid altitude loss and the control feedback issues resulted in the landing occurring past the intended touchdown point.
The investigation
Examination of the event focused on the pilot's account of the control forces. The primary finding was the discrepancy between the pilot's expectation of control response and the actual mechanical feel of the spoilers. No mechanical failure of the glider itself was cited as a cause, but rather the pilot's interpretation of the control stiffness during a critical phase of flight.
