Event Sequence
On 6 October 2024 at approximately 12:00 local time, an L-13 SW VIVAT motor glider, registration HA-1290, was preparing for a private VFR flight from Dunakeszi Airport (LHDK). The pilot arrived at the airfield during the morning hours and conducted a pre-flight inspection in the hangar, finding the aircraft suitable. After towing the aircraft to the apron, he fueled it with 50 liters of 100-octane automotive gasoline. During taxi, the pilot left the canopy open, having heard over the radio that a preceding Scheibe SF-25 Falke was conducting a training flight with a student and instructor, which he expected would take considerable time before takeoff. Consequently, he delayed closing the canopy.
During takeoff on runway 29, the canopy opened. The pilot attempted to close it but was unsuccessful. He decided to continue the flight, but the aircraft stalled and impacted a container at an industrial site located approximately along the extended runway centerline.
Injuries and Damage
The pilot suffered serious injury. The aircraft was significantly damaged.
