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/owner of the tailwheel-equipped biplane performed two low approaches prior to landing in order to "judge" the direction and speed of the wind. The pilot then performed a "wheel landing" to runway 10, a 4,300-foot-long, 75-foot-wide asphalt runway. However, by touchdown, the wind speed and direction had changed, which raised the left wing. The pilot corrected for the lifting of the wing, but the heading of the airplane diverged 10 to 15 degrees to the left of runway heading. At that point, the pilot elected to continue into the snow-covered apron, rather than struggle to maintain runway alignment, and risk the loss of aircraft control. The airplane's main landing gear "caught" as it entered the snow, the airplane nosed over, and came to rest inverted with substantial damage to the vertical stabilizer. The pilot stated that there were no preimpact mechanical anomalies with the airplane that would have precluded normal operation. The recorded wind at the airport, about the time of the accident, was from 010 degrees at 9 knots, gusting to 16 knots.

NTSB Probable Cause

The pilot's failure to maintain directional control while landing in a gusty crosswind, which resulted in a runway excursion and a nose over.
