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 tail wheel equipped airplane landed hard after the student pilot performed a series of touch-and-go takeoffs and landings. The airplane travelled off the runway to the left and came to rest in the grass. The pilot sustained serious injuries, which prevented him from recalling the accident circumstances. The airplane sustained substantial damage to the fuselage and both wings. Examination of the airplane’s flight control system did not reveal any mechanical failures or malfunctions that would have precluded normal operation.
