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
NYC06CA141
The Maule M-5-180C airplane touched down on the main landing gear, and then the tailwheel touched down shortly thereafter. The pilot then experienced a "very strong pull to the left," and attempted to correct with aileron and rudder. The airplane departed the runway to the left, struck the wing, and came to rest upright. Examination of the tailwheel revealed that the retention clip for the right compression spring was missing, and the spring had disconnected from the swing arm. The retention clip was not recovered.
NTSB Probable Cause
The disconnected tailwheel compression spring, which resulted in a loss of directional control.
