Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

NTSB Number
CEN12CA029
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
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.
Full Narrative
The pilot/builder was planning a short flight above the runway for the purpose of testing the newly built gyrocopter. During the takeoff roll, the nose wheel experienced a shimmy and the pilot was unable to maintain directional control. The gyrocopter rolled onto its left side and exited the side of the runway before coming to rest in the grass. During the rollover, the main rotor mast was substantially damaged. A postaccident examination of the gyrocopter revealed a loose bolt in the nose gear steering linkage which allowed the nose wheel to shimmy.
