The defining event best describes what happened. - [Landing-landing roll: Runway excursion](https://openairdocs.org/ntsb-events/300) (defining event); cases with it: [Beech A36, 20 cases](https://openairdocs.org/ntsb-events/300/sequence.md?model=1151604), [All aircraft, 3,643 cases](https://openairdocs.org/ntsb-events/300/sequence.md) ## 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. ## Factual narrative 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."
