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.

SEA07CA116
During the takeoff roll in a 30 degree crosswind of about 12 knots, the aircraft passed on the leeward side of a number of hangars of varying size. As the aircraft passed through the area where the wind was blocked by the individual hangars into areas where the wind was not blocked, the student pilot failed to adequately compensate for the resultant change in wind velocity and direction. As the student pilot continued the takeoff, the aircraft departed the side of the runway, impacted a taxiway exit sign, and entered into an area of wet, soft ground. The student pilot then pulled the power to idle and applied "full brakes." The nose gear then dug into the terrain and ultimately collapsed. There were no anomalies found in the rudder or nose wheel steering systems.
NTSB Probable Cause
The student pilot's failure to adequately correct for changing wind conditions, leading to a loss of directional control during the takeoff ground roll. Factors include wet, soft terrain along the side of the runway.
