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
CEN14CA455
While cruising in smooth air conditions with no clouds in the area and with the autopilot on and the seat belt sign off the airplane had a brief encounter with what the flight crew described as wake turbulence. The momentary turbulence resulted in a sharp roll deviation of about 15 to 20 degrees. The turbulence lasted for less than five seconds then returned to smooth air conditions. One of the two flight attendants who had been standing in the rear galley was seriously injured and the other flight attendant sustained a minor injury. No significant turbulence had been forecast, and the flight crew had not overheard any airplanes in the area reporting turbulence. Immediately after the encounter, the airplane continued in smooth air conditions.
NTSB Probable Cause
The airplane's inadvertent encounter with wake turbulence during cruise flight, which resulted in a serious injury to a flight attendant.
