What happened
On May 9, 2015, a Standard Cirrus glider, registration OK-6394, was conducting a flight originating from Šumperk (LKSU). After approximately two hours of flight, the pilot was unable to maintain altitude due to insufficient thermal lift and decided to perform a field landing near the village of Malá Morava u Hanušovic.
Upon selecting a suitable grassy area and completing a reconnaissance turn, the pilot proceeded with the approach. During the landing maneuver, the aircraft struck an undetected terrain irregularity, causing the glider to bounce. In an attempt to manage the bounce, the pilot applied excessive downward control input, resulting in a hard impact where the nose of the aircraft struck the ground. There were no injuries to the pilot.
The investigation
The ÚZPL_PLN investigation examined the flight sequence, the meteorological conditions, and the aircraft's technical state. The investigation reviewed data from the pilot and the Czech Police, who attended the scene and confirmed the pilot was not under the influence of alcohol. The investigation also assessed the aircraft's maintenance records and the pilot's qualifications.
Findings
- The pilot was properly qualified and the aircraft was airworthy with valid maintenance inspections.
- The meteorological conditions were favorable, with good visibility and light thermal turbulence.
- The primary cause of the accident was the pilot's incorrect reaction to the aircraft's bounce during the landing flare.
- The excessive downward pressure on the control column caused the nose to strike the terrain, resulting in cracks in the composite fuselage skin and damage to both landing gear fairings.
