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 reported that, during the landing the airplane touched down about halfway down the runway. He applied heavy braking when he noticed the runway end was approaching. The airplane subsequently overran the runway end and collided with a fence. The right wing was substantially damaged. The pilot initially reported that the brake system did not function as expected; however, a brake system examination did not reveal any preaccident mechanical failures or malfunctions that would have precluded normal operation. The pilot later stated that the airspeed was likely too fast when he touched down, which resulted in a runway overrun.
