What happened
On June 6, 2026, at the Krosno aerodrome (EPKR), a student pilot completed three supervised flights before being authorized for a solo training exercise focused on landing refinement. The initial tow and part of the circuit were executed correctly. However, due to higher altitude, the student decided to perform an extra turn in the upwind position. This resulted in the third turn of the circuit being flown too far from the runway. Consequently, after the fourth turn, the student deployed the air brakes prematurely. The SZD-50-3 Puchacz found itself at a low altitude outside the aerodrome boundaries. During the final approach phase, the wing struck a tree, causing an uncontrolled spin and impact with the airfield fence. The pilot sustained no injuries, but the glider was seriously damaged.
The investigation
The Polish State Commission for Aviation Accident Investigation (PKBWL) reviewed the findings from the investigating entity and deemed them sufficient to close the case. The analysis focused on the sequence of events during the solo flight, specifically the management of altitude and circuit geometry. Investigators examined how the student prepared for the landing, including the configuration of the glider and the timing of air brake deployment. They also assessed the supervisory role of the instructor and the operational environment, such as the availability of the landing area.
Findings
The primary cause was identified as an improper circuit construction combined with poor altitude management, which stemmed from inadequate preparation for solo flights. Contributing factors included:
- Inadequate or absent landing planning, likely compounded by incorrect glider configuration (too flat an approach) and improper use of aerodynamic brakes.
- Insufficient supervision by the instructor, who failed to observe and anticipate the student's behavior.
- Potential misplacement of takeoff/landing markers that did not account for obstacles on the approach path.
- Limited landing space due to other gliders occupying the runway area, which were not removed in time for the student's landing.
