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.

The pilot said that his pilot-certificated passenger was landing the tail-wheel airplane when he lost directional control during the landing roll. As the airplane was departing the runway, the pilot took over the flight controls in order to direct the airplane to the adjacent runway. The airplane impacted a gopher hole and nosed over. The engine firewall and vertical stabilizer were wrinkled, and three lift struts and both wing spars were bent.
NTSB Probable Cause
The pilot-certificated passenger's failure to maintain directional control during landing and the pilot's delayed remedial action and inadequate supervision.
