What happened
On May 13, 2018, at 12:56 LMT, a pilot launched a SZD-48-3 Jantar Standard 3 glider from the Elbląg Aeroclub (EPEL) using a winch launch. The intention for the flight was to perform thermal soaring; however, after reaching an altitude of approximately 350 meters, the pilot was unable to locate any thermal lift. Consequently, at an altitude of about 100 meters, the pilot initiated a fourth circuit for landing on runway 10.
During the approach, the pilot maintained level flight and flare just before the runway threshold, positioned to the right of the runway centerline. As the aircraft touched down approximately 30 meters from the runway, the right aerodynamic brake panel caught on tall grass located in that area of the airfield. This caused the glider to enter a ground loop (a right-hand turn) before coming to a complete stop. The pilot was uninjured and able to exit the aircraft unaided.
The investigation
The investigation, conducted by the operator, examined the flight sequence and the environmental conditions at the time of the incident. The investigation reviewed the pilot's experience, noting that while the pilot held the necessary glider pilot license (SPL) and had 1,037 total flight hours, recent flight frequency had been low. The investigation also assessed the aircraft's condition and the landing area's surface vegetation.
Findings
- The primary cause of the incident was improper planning of the landing approach.
- The landing was performed off the prepared runway surface in an area of tall grass.
- The aerodynamic brakes were in the extended (open) position during the landing roll.
- The right aerodynamic brake panel made contact with the tall grass, leading to the loss of directional control.
