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 an instructional flight, the radio and intercom failed. The instructor returned to the airport and received a green light from the tower air traffic controller to land. During touchdown, the airplane "ballooned," touched down again, and then veered right and ground looped. The airplane sustained substantial damage to the left wing. The instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
