Aircraft Accident/Incident Report
Lubbock, Texas 79413
Saturday, September 8, 2007 10:30 CDT
NTSB Narrative Summary Released at Completion of Accident
A flight instructor was providing flight instruction to a commercial pilot leading to a tailwheel endorsement. Toward the end of the instructional period, the flight instructor demonstrated wheel landings, which the pilot receiving instruction was able to perform satisfactorily. The flight instructor reported that while executing another wheel landing on Runway 17, the commercial pilot started to lose directional control, overcorrected, and used excessive differential braking. The tailwheel-equipped airplane pitched forward and subsequently nosed-over, coming to rest in the inverted position. Runway 17 was reported to be 4,000-foot long by 75-foot wide. The winds were reported as calm and the asphalt runway was dry. The flight instructor added that the directional control could have been corrected with an application of power rather than by brake application. Additionally, the flight instructor reported that there were no anomalies or malfunctions in the airplane's flight controls or tailwheel steering system.
NTSB Probable Cause Narrative
The pilot's failure to maintain directional control of the airplane while landing. A contributing factor was the flight instructor's delay in taking remedial action.
