Probable cause
The student pilot failed to maintain directional control during landing roll due to improper use of the flight controls.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The student pilot reported that the acft touched down on the main gear with the right wing slightly low, bounced slightly, and then veered to the left. She said the power was off but she didn't hold the control wheel back firmly and the airplane continued to ground loop. The landing was made on an asphalt runway, 4,100 x 75 ft and the wind was calm.
