Primary finding
Probable cause
The pilot's decision to perform a touch-and-go on unsuitable terrain, which resulted in a loss of directional control and a rollover.
Investigator assessment
Analysis narrative
The pilot of a gyroplane reported that during a touch-and-go on a sand bar, the nose wheel began to dig into soft sand. The pilot further reported that he turned the nose wheel to the left towards firmer sand, but the spring-loaded nose wheel dug further into the sand and suddenly turned "full left." Subsequently, the gyroplane rolled over to the right, which resulted in substantial damage to the rudder. The pilot reported that the throttle quadrant friction-set screw had become loose while in-flight, but the mechanical malfunction did not occur during the touch-and-go phase of flight.
