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.

CEN11CA143
The pilot was landing his single-engine experimental airplane in calm wind conditions, when the left main gear collapsed upon touchdown. The airplane veered to the right and the pilot attempted to keep the airplane on the runway by applying engine power and right aileron; however, the airplane exited the runway and spun, which resulted in structural damage to the fuselage. A postaccident examination of the left main landing gear strut revealed that the strut failed due to a pre-existing crack in the weld joint. The crack would not have been readily visible to the pilot during a pre-flight inspection due to the construction of the strut. The bracing around the strut exhibited signs of distress with twisted and shiny fracture surfaces. No other anomalies were found with the airplane.
NTSB Probable Cause
Failure of the left main landing gear strut due to a pre-existing crack in the weld joint.
