Analysis

The pilot was demonstrating various maneuvers in his gyrocopter at an air show. He entered a left vertical spin and noted the entry was sluggish. When he added power to aid in spin development, the rudder jammed full left. Efforts to recover were to no avail and the gyrocopter impacted terrain next to the airport runway. Postaccident examination disclosed the leading edge of the fiberglass rudder had delaminated and had jammed the rudder in the full left position.
