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.

A 250 HOUR PRIVATE PILOT WAS UNDERGOING FINAL INSTRUCTION IN PREPARATION FOR AN UPCOMING MULTIENGINE RATING CHECKRIDE. THE AIRPLANE WAS OBSERVED ON AN EASTERLY HEADING UNDER A 3,500 CLOUD COVER. POWER TO BOTH ENGINES WAS INTERRUPTED AND A GLIDE ESTABLISHED WITH GEAR AND FLAPS EXTENDED. A FEW SECONDS LATER, THE POWER WAS REESTABLISHED AND A CLIMB ATTITUDE ESTABLISHED. A SMALLER SECONDARY POWER REDUCTION WAS HEARD, AND THE AIRPLANE SNAPPED INTO A SPIN. RECOVERY WAS INITIATED, BUT IT WAS NOT POSSIBLE DUE TO THE LOW ENTRY ALTITUDE.
NTSB Probable Cause
THE LOSS OF DIRECTIONAL CONTROL AS RESULT OF THE VELOCITY MINIMUM CONTROL AIRSPEED NOT BEING MAINTAINED. A FACTOR WAS THAT THE MANEUVER WAS INITIATED AT AN INADEQUATE ALTITUDE TOO LOW FOR THE PILOT TO RECOVER.
