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 airplane departed the left edge of the runway and impacted snow covered terrain while landing on runway 8L (5,000 feet by 75 feet, asphalt). The pilot reported that upon touchdown "the airplane started skidding to the left" and that the "left wheel was shaking violently." The pilot stated he "applied right rudder and right brake aggressively" in an effort to keep the airplane on the runway. The pilot reported the airplane departed the runway onto snow covered ground. The pilot stated the airplane sunk through a hard layer of snow, causing the propeller to strike the ground and the left wing to "hit the snow." The wind conditions at the time of the accident were from 170 degrees magnetic at 13 knots, gusting to 18 knots.
NTSB Probable Cause
The pilot's inadequate compensation for the wind conditions and failure to maintain directional control. Factors were the gusting crosswind conditions and the snow covered ground.
