Aircraft Accident/Incident Report

Blair, Nebraska 68008
Saturday, October 15, 2011 11:15 CDT

NTSB Narrative Summary Released at Completion of Accident

During the takeoff roll, the nosewheel experienced a shimmy, and the pilot was unable to maintain directional control. The gyrocopter rolled onto its left side, exited the side of the runway, and came to rest in the grass. During the rollover, the main rotor mast sustained substantial damage. A postaccident examination of the gyrocopter revealed a loose bolt in the nose gear steering linkage, which allowed the nosewheel to shimmy. The pilot, who was also the builder, was testing the newly built gyrocopter.

NTSB Probable Cause Narrative

The pilot/builder’s inadequate installation of a nosewheel steering component, which resulted in a shimmy and a loss of directional control during the takeoff roll.
