Introduction
A dual instructional flight in a Cessna 140 concluded with the aircraft nosing over during the landing rollout. The purpose of the flight was for an instructor pilot to provide a checkout for a private pilot transitioning to a conventional gear aircraft.
Flight Events
The flight included a series of uneventful full-stop and touch-and-go landings. Following these, the student pilot was directed to perform a landing. Both the certified flight instructor (CFI) and a ground-based witness reported that the aircraft landed normally.
Incident Description
During the final portion of the rollout, the surface wind introduced a tailwind component, according to the witness. The CFI reported that her student "came up on the brakes" and she instructed him to stop braking. Despite her efforts to prevent the nose-over by applying back pressure to the control yoke, she lost control and the aircraft nosed over.
Outcome
The aircraft sustained a nose-over. Additional details about damage or other consequences were not specified.
