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, he flew the visual approach high to avoid a berm on the approach end of the runway and the airplane touched down "at or just after the first 1/3 of the runway." He then applied max braking, but the airplane overran the end of the runway, and sustained substantial damage to the engine mount and right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
