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.

CHI07CA110
The airplane impacted terrain while on final approach to runway 22 (3,120 feet by 24 feet, asphalt). The student pilot stated that the airplane "was caught in a downdraft/wind shear and was not able to clear perimeter fence, even with application of full power." The pilot reported there was a small valley to the northeast of the airport which "probably caused the downdraft." An on-scene investigation revealed that the airplane impacted the radio-antenna of a passenger vehicle operating on the road adjacent to the airport. The airplane then impacted a rising embankment and proceeded through the airport perimeter fence, coming to rest short of the approach threshold. The student pilot was flying with an expired 90 day solo endorsement and did not have a medical certificate. The student pilot was operating the airplane as a light-sport pilot. A local weather reporting station reported the winds were from 260 magnetic degrees at 4 knots at the time of the accident.
NTSB Probable Cause
The student pilot's failure to maintain proper glidepath to the runway. Contributing factors to the accident included the passenger vehicle, the rising embankment, and the airport perimeter fence.
