Occurrence
On 17 August 2025, at the EPRU aerodrome (Rudniki near Częstochowa), a Schleicher ASW 19B glider, registered SP-4153, was engaged in soaring flights. After a four-hour thermal flight, the pilot (holder of a SPL license) set up a circuit for landing on the grass runway 26R.
Sequence of Events
Due to thermal activity and air turbulence, the pilot maintained an increased approach speed, reported as 110–120 km/h, with spoilers partially deployed. Upon touchdown, the glider bounced (kangaroo), and the pilot responded by pushing the control stick forward decisively. The glider then touched down on its nose, simultaneously catching the right wingtip on the grass. The resulting force couple caused an uncontrolled yaw (ground loop) and a fracture of the fuselage in the tail section. The canopy also cracked.
Injuries and Damage
The pilot sustained no injuries. The glider was substantially damaged.
Investigation Findings
The Polish State Commission on Aircraft Accident Investigation (PKBWL) analyzed the report and concluded that the information was sufficient to close the investigation without further inquiry. The commission identified the following causes and contributing factors:
1. Lack of a proper flare and hold-off phase before touchdown, resulting in a hard landing and bounce. 2. Incorrect pilot reaction after the bounce, leading to a nose-first landing at increased speed. 3. Failure to maintain lateral balance, causing the wingtip to strike the runway surface after the nose impacted first.
Safety Recommendations
No preventive actions or safety recommendations were formulated by the investigating entity or the commission.
