What happened
A routine solo flight involving a student pilot ended in a fatal accident at the Rockton Airport. The aircraft, a Pezetel SZD-51-1 glider with registration C-FICQ, was performing a local flight from the SOSA Gliding Club. After the scheduled flight duration had passed without radio contact, a duty instructor observed the glider entering the landing circuit.
During the final approach to Runway 1s/36, the aircraft was noted to be flying at an excessive speed and altitude. While the glider was approximately 300 feet above the ground, no air brake deployment was observed. As the aircraft progressed toward the runway, the air brakes were partially deployed and then retracted, causing the aircraft to pitch nose-down and enter a series of oscillations. As the glider crossed the runway at roughly 25 feet above the ground, the air brakes were fully extended. This action coincided with a steep 45-degree nose-down pitch, causing the aircraft to strike the ground. The impact resulted in one fatality.
The investigation
The investigation focused on the mechanical state of the Pezetel SZD-51-1 and the flight controls. Investigators examined the elevator, rudder, and aileron systems, finding no evidence of mechanical jams or failures; all damage was attributed to the impact. The air brake system was also found to be functioning normally. The pitch trim was inspected and found to be in a position consistent with the aircraft's weight and center of gravity.
Regarding the pilot, the investigation noted that while the student was qualified and experienced in other club gliders, this was their first flight in this specific model. The cockpit seat was adjusted forward to accommodate the pilot's height, a position that, while making air brake operation slightly more awkward, did not prevent full deployment. Radio equipment and batteries were confirmed to be fully operational.
Findings
- The aircraft was flying at a ground speed of 60 to 65 knots during the final stages of the approach, exceeding the recommended 50 knots.
- The pilot was likely attempting to manage a high-speed, high-altitude approach by using aggressive control inputs.
- The pilot likely applied forward stick input simultaneously with air brake deployment to force the aircraft down to meet the remaining runway length.
- The pilot's lack of familiarity with the specific flight characteristics of the Pezetel SZD-51-1 may have contributed to the improper approach technique.
