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 pilot of the tailwheel-equipped airplane reported that, during landing after the tail had settled, he applied the brakes too hard. Subsequently, the airplane nosed over and came to rest inverted. The airplane sustained substantial damage to left wing, right wing lift strut, and empennage. The pilot reported no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation. As a recommendation, the pilot added that he should not have applied the brakes as hard.
