## Sequence of events

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

- [Landing-landing roll: Nose over/nose down](https://openairdocs.org/ntsb-events/096) (defining event); cases with it: [Cubcrafters CC11-160, 10 cases](https://openairdocs.org/ntsb-events/096/sequence.md?model=060006N), [All aircraft, 2,287 cases](https://openairdocs.org/ntsb-events/096/sequence.md)

## Analysis

The pilot of the tailwheel-equipped airplane was performing a wheel landing to the turf adjacent to an asphalt runway. Prior to the tailwheel contacting the ground, the pilot moved his toes to top the rudder pedals and inadvertently applied the brakes. The airplane then nosed over and came to rest inverted, which resulted in substantial damage to the left-wing strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
