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.

NTSB Number
WPR13CA146
The pilot reported that, during the landing roll in light and variable wind, a “puff” of wind from the east caused the tail, which was on the runway, to swing around. The pilot added power in an attempt to regain directional control; however, he did not apply power soon enough. The right wing touched the runway, and the airplane impacted a taxiway intersection sign. The airplane's wing spars were structurally damaged, and the upper right wing tip was crushed. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's failure to adequately compensate for crosswind conditions, which resulted in a loss of directional control during the landing roll.
Full Narrative
The pilot stated that he was performing touch-and-go landings in light and variable wind at 5 knots. During a landing roll, with the tail wheel on the runway, a puff of wind from the east caused the tail to swing around. The pilot added power in an attempt to regain directional control, when the right wing touched the runway and the airplane impacted a taxiway intersection sign. The airplane's wing spars were structurally damaged and the upper right wing tip was crushed. The pilot stated that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
