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
ERA11CA375
The pilot reported that, during the takeoff roll, he was unable to correct an uncommanded left yaw with control inputs, so he elected to abort the takeoff. During rollout, the airplane departed the left side of the runway and the landing gear collapsed, which resulted in substantial damage to the right wing spar. A postaccident examination revealed that a "nicopress" fitting on the left rudder cable had failed and disconnected from its bell-crank. The cable fitting had been pressed with an improper tool or technique at installation. The airplane's entire flight control system had been refitted and re-rigged approximately 9 years prior to the accident.
NTSB Probable Cause
The improper installation of the right rudder control cable by maintenance personnel, which resulted in the pilot's inability to maintain directional control during takeoff.
Full Narrative
During the takeoff roll, an uncommanded left yaw could not be corrected with control inputs, so the pilot elected to abort the takeoff. During rollout, the airplane departed the left side of the runway, and the landing gear collapsed, which resulted in substantial damage to the left wing spar. Examination by a Federal Aviation Administration inspector revealed that a "nicopress" fitting on the right rudder cable had failed, and disconnected from its bell-crank. According to the Inspector, the cable fitting had been pressed with an improper tool or technique at installation. The airplane's entire flight control system was refitted and re-rigged approximately 9 years prior to the accident.
