Event
A commercial pilot had recently purchased a conventional gear airplane from a certified flight instructor (CFI). The pilot requested a checkout flight to familiarize with the aircraft.
Sequence of Events
During the checkout, the CFI verbally guided the pilot through the first landing. Subsequently, the CFI took control of the airplane with the intention of demonstrating a three-point touchdown. According to the CFI, nothing unusual occurred during the approach and touchdown except that the airplane veered to the right during the rollout. The CFI attempted to correct the veer by applying left rudder, but the airplane continued rolling to the right. The airplane departed the side of the runway, entered a dirt area, and nosed over.
Investigation Findings
No mechanical failures or malfunctions were encountered during the event. The airplane sustained damage from the nose-over, but the source does not specify the extent or occupant injuries.
