Glider accident at Medlánky airfield

Incident Overview and Aircraft Details On 13 May 2018, an L 13 A Blaník glider with the registration OK-0931 was involved in an accident at Medlánky airfield. The aircraft was operated by a legal entity and manufactured by LET, n. p. Kunovice. The incident occurred at 17:00 UTC during a spring training flight. The glider was being flown in dual control by an instructor and a pilot, who was practicing landings in a restricted area. ## Sequence of Events Following a tow release at approximately 350 meters above the airfield, the pilot initiated an approach to runway 16. The pilot adjusted the landing plan using a slip with full flaps. Just before the edge of the airfield, the glider sank into a field of grown rapeseed. This contact caused the aircraft to rotate approximately 180 degrees in the opposite direction. ## Damage and Injuries The investigation identified damage to the left and right horizontal tail surfaces, as well as a bulkhead in the rear section of the fuselage. Neither the instructor nor the pilot sustained injuries. A breath alcohol test conducted by the Czech Police for both individuals returned a negative result. ## Investigation and Regulatory Context The investigation was conducted by the Institute for Expert Investigation of Causes of Aircraft Accidents in accordance with European Union Regulation No. 996/2010, Czech Act No. 49/1997 on Civil Aviation, and Annex 13 to the Convention on International Civil Aviation. The final report was issued in August 2019. The investigation's sole purpose was the prevention of future accidents and incidents, without determining fault or liability.
