What happened
On May 5, 2018, a pilot was conducting winch-launched flights at the Gliwice Aeroclub (EPGL) in an SZD-51-1 Junior. During the second flight of the day, the pilot was performing an approach to runway 09. Due to the presence of a crosswind, the pilot maintained a higher approach speed of approximately 100-110 km/h.
At approximately 14:26 LMT, while at an altitude of about 8 meters, the pilot closed the air brakes and applied a pitch-up control input. The pilot stated that this maneuver was intended to avoid two individuals who were on the approach path and were not observing the glider. Consequently, the SZD-51-1 Junior struck the grassy surface without a proper flare phase and at a significant pitch angle. The impact caused the nose of the fuselage to hit the ground, leading the aircraft to bounce to a height of approximately 1 meter. The glider traveled roughly 200 meters before coming to a complete stop. The pilot sustained no injuries.
The investigation
The investigation examined the flight sequence, the pilot's maneuvers, and the environmental conditions at the time of the incident. The inquiry focused on the pilot's decision to alter the approach profile to avoid obstacles on the airfield and the subsequent lack of a leveling phase prior to touchdown.
Findings
- The primary cause of the incident was a pilot error involving improper flying technique, specifically the failure to execute the flare phase during the landing.
- The pilot's decision to close the air brakes and change the approach angle was driven by the need to avoid two people on the approach path.
- The presence of a crosswind necessitated a higher approach speed of 100-110 km/h.
- The impact resulted in structural damage to the fuselage, and the aircraft was grounded pending repairs.
