Overview
On a local flight from Rockton Airport, a student pilot flying a single-seat Pezetel SZD-51-1 glider (registration C-FICQ, serial number B-2150) encountered difficulties during the final approach to Runway 18/36. The glider was observed entering the circuit after the duty instructor was unable to establish radio contact. On final approach, the glider exhibited unusual pitch oscillations and a nose-down attitude before striking the ground. The cockpit sustained substantial damage.
Pilot and Aircraft Information
The student pilot held a valid student pilot permit and was qualified for the flight. The pilot was a regular club member with 80 previous flights, including five solo flights on other club gliders. However, this was the pilot's first flight on the Pezetel SZD-51-1, which is considered a slightly higher performance glider. The aircraft was manufactured in Poland in 1996, imported to Canada in 2006, and had a valid certificate of airworthiness. No pre-impact mechanical failures were found.
Flight Sequence
The flight was scheduled for approximately one hour. At the expected return time, the duty instructor attempted radio contact but received no response. The glider was later seen entering the circuit and was observed on final approach. At an estimated height of 300 feet above ground level, air brakes were expected to be deployed but were not. The glider then pitched nose-down in a steep attitude, and air brakes were partially extended and quickly retracted. A series of pitch oscillations occurred before the aircraft stabilized. As it continued over the runway at about 25 feet agl and an estimated ground speed of 60-65 knots (recommended approach speed is 50 knots), the air brakes were fully deployed, and the glider pitched nose-down approximately 45° and struck the ground.
Examination Findings
Post-accident examination of the flight controls, including elevator, rudder, aileron, and air brakes, revealed no pre-impact abnormalities. The pitch trim was found between the third and fourth notch, within expected range. The seatback was adjusted forward to accommodate the pilot's stature, which moved the pilot closer to the controls but slightly forward of the air brake lever. Full air brake deployment was possible but more awkward. The hand-held radio used by the instructor and the glider's radio battery were found serviceable.
Weather and Runway Conditions
Weather at the time was scattered clouds, light north-northwest winds, and temperature 22°C. Runway 18/36 is grass-covered, 2600 feet long and 200 feet wide, with a displaced threshold of 250 feet. Beyond the runway are tall grass and tall trees.
Analysis of the Occurrence
The pilot was trained and had solo experience, but this was the first flight on the Pezetel SZD-51-1. The flight appeared normal until final approach. The lack of air brake deployment at 300 feet resulted in high speed and altitude. The subsequent pitch-down and oscillations suggest attempts to lose altitude. The pilot may have been hesitant to use air brakes due to previous pitch control issues, leading to a long-landing situation. The final pitch-down may have resulted from simultaneous air brake deployment and forward stick input.
No evidence of incapacitation or physiological factors was found. Weather was not a factor.
