What happened
During a solo cross-country flight intended as a final training session for a touring motor glider rating, a pilot encountered difficulties while approaching Ludvika airport. After observing a windsock and noting a sailplane parked at the end of runway 19, the pilot prepared for landing. As the aircraft crossed the runway threshold, the pilot attempted to ensure the throttle was fully closed but inadvertently increased engine power.
Under the pressure of the reduced available runway length caused by the parked glider, the pilot decided to abort the landing and execute a go-around. During this maneuver, the pilot applied full throttle while the airbrakes likely remained extended. This combination, along with a forward movement of the control stick, caused the motor glider to strike the runway instead of climbing. The impact caused the aircraft to bounce into the air, at which point the pilot lost control. A subsequent backward pull on the control stick induced a stall, leading to a heavy impact with the runway. The aircraft skidded on its lower fuselage before coming to a halt. The pilot sustained minor injuries and was able to exit the wreckage before rescue services arrived.
The investigation
The Swedish Accident Investigation Authority examined the sequence of events leading to the loss of control. The investigation focused on the pilot's actions during the critical moments of the go-around maneuver and the configuration of the aircraft's aerodynamic surfaces. The inquiry also looked into the training standards for touring motor gliders and the specific operational complexities of the aircraft type involved.
