## Probable cause

The pilot’s failure to control the pitch attitude of the gyroplane during landing, which resulted in a loss of control, runway excursion and collision with terrain.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Sequence of events

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

- [Landing: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Bryan S Happell TANGO2, 1 case](https://openairdocs.org/ntsb-events/230/sequence.md?model=05639E9), [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md)

## Analysis

The pilot of the gyroplane reported that, during a touch-and-go landing to the runway, the gyroplane floated, and the front wheel contacted the runway. He attempted to regain control, but the gyroplane veered off the runway and came to rest on its side. The gyroplane sustained substantial damage to the empennage and rotor system. The pilot reported that there were no preaccident mechanical failures or malfunctions with the gyroplane that would have precluded normal operation.
