Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The flight instructor reported that during the landing roll the airplane veered left. The pilot receiving instruction applied a "sharp application" to the right brake. The flight instructor further reported that he directed the pilot receiving instruction "off the brakes", a total of three times. As a result of the right brake application, the airplane ground looped to the right, the left main landing gear collapsed, and the left wing impacted the ground, which resulted in substantial damage to the left wing. The flight instructor reported that there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
