Incident Overview
A flight instructor was providing instruction to a commercial pilot working toward a tailwheel endorsement. Toward the end of the instructional period, the instructor demonstrated wheel landings, which the pilot performed satisfactorily. While executing another wheel landing on Runway 17, the commercial pilot lost directional control, overcorrected, and used excessive differential braking. The tailwheel-equipped airplane pitched forward and subsequently nosed over, coming to rest inverted.
Details of the Flight
Runway 17 was 4,000 feet long and 75 feet wide. Winds were calm, and the asphalt surface was dry. The flight instructor noted that directional control could have been corrected with an application of power rather than by brake application. No anomalies or malfunctions were reported in the airplane's flight controls or tailwheel steering system.
Outcome
The airplane came to rest in an inverted position on the runway. The source does not specify injuries or damage to the aircraft beyond the nose-over.
