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 reported that the runway had about 12 inches of new snow and the runway edge lights were not visible. During the takeoff run, in flat light conditions, he was unable to determine the centerline of the runway, and the airplane subsequently drifted left of centerline. The left main landing gear impacted a snow berm along the edge of the runway and the airplane spun around 90°, which resulted in substantial damage to the right wing. The pilot reported that there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation.
NTSB Probable Cause
The pilot’s failure to maintain directional control during takeoff in flat light conditions which resulted in a loss of control and impact with a snow berm.
