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
CEN12CA503
As the airplane approached the destination airport, the pilot monitored the airport’s automated weather reporting station. The pilot stated that the airport’s reported wind changed from 160 degrees at 7 knots, to 200 degrees at 9 knots, and then to 180 degrees at 8 knots as they got closer to the airport. The pilot added that he initially planned to land on runway 26, but, upon circling the airport, he noted that the windsock favored runway 8. During the landing roll on runway 8, the airplane’s right wing lifted. The pilot stated that he was unable to lower the wing, and the airplane veered right and continued off the side of the runway. The airplane came rest in the grass with substantial damage to the fuselage just forward of the empennage. The pilot did not report any mechanical problems with the airplane.
NTSB Probable Cause
The pilot’s loss of directional control during the landing roll in a variable crosswind, which resulted in a runway excursion.
Full Narrative
The pilot and two passengers departed on a cross-country flight. As they approached their destination airport, the pilot monitored the airport’s automated weather reporting station. The pilot stated the airport’s wind condition changed from 160 degrees at 7 knots, to 200 degrees at 9 knots, and then to 180 degrees at 8 knots, as they got closer to the airport. The pilot added that he made his initial approach to runway 26, but upon circling the airport, the windsock favored runway 8. During the landing roll, the airplane’s right wing lifted. The pilot stated he was unable to lower the wing, the airplane veered right, and continued off the side of runway 8.
