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
GAA16CA154
The pilot reported that while landing on a grass airstrip, the nose landing gear "caught" on the soft turf and collapsed. The airplane slid about 60 feet, the forward portion of the fuselage impacted terrain, and the airplane nosed over. The airplane sustained substantial damage to the fuselage, rudder, vertical stabilizer, and firewall. The pilot verified that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. As a safety recommendation, the pilot reported to keep the nose landing gear off the ground longer during the landing.
NTSB Probable Cause
The pilot's improper soft-field landing technique, which resulted in a nose landing gear collapse and a nose over.
