Incident Details
A pilot was practicing touch-and-go landings. The pilot had been operating the aircraft with the mixture control set to a leaned position. Following a landing, the pilot applied full throttle. The engine responded with coughing and sputtering. To address this, the pilot advanced the mixture control to the rich setting. Around the same time, the aircraft began to veer to the right. It departed the runway surface, struck a sand dune, and subsequently nosed over.
The pilot had recently transitioned to flying a tailwheel-equipped aircraft. No other details about the aircraft, location, or any injuries were provided.
