## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Takeoff: Collision during takeoff/land](https://openairdocs.org/ntsb-events/490) (defining event); cases with it: [Beech 23, 2 cases](https://openairdocs.org/ntsb-events/490/sequence.md?model=1151202), [All aircraft, 1,309 cases](https://openairdocs.org/ntsb-events/490/sequence.md)

## Analysis

The pilot reported that during the takeoff roll, he “saw rotate speed” and then pitched for best climb speed. He had no further memory of the event. A witness reported that they saw the airplane lift off from the runway and remain in ground effect until it crossed the departure end of the runway. As it crossed the departure end of the runway, it was in a left bank and then struck a tree. The airplane impacted a public beach and came to rest upright, in shallow water. The wings and fuselage sustained substantial damage. At 1535, the temperature was 30°C, the dewpoint was 4°C, and the altimeter setting was 29.98. The calculated density altitude was 4,790 ft. The pilot reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation.
