What happened
A pilot was performing local area recurrent training in a tailwheel-equipped airplane accompanied by a second pilot. The flight operations involved approximately 10 takeoffs and landings on a gravel surface airstrip measuring 3,000 feet in length and 75 feet in width.
During the subsequent landing, the aircraft touched down approximately 12 to 14 feet to the right of the unmarked runway centerline. In an attempt to realign the aircraft with the center of the runway, the pilot momentarily over-controlled the airplane, causing it to veer toward the right side of the runway. As the aircraft moved off the paved surface, the pilot applied excessive braking, which resulted in the brakes locking and causing the airplane to nose over.
The aircraft sustained damage to the propeller, engine mount, left wing lift strut, vertical stabilizer, and the rudder. The pilot was not injured.
