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.

THE SECOND PILOT HAD JUST REBUILT THE EXPERIMENTAL AIRPLANE. HAVING NEVER FLOWN THIS TYPE OF AIRPLANE, AND HAVING NOT FLOWN IN THE LAST 90 DAYS, HE ASKED ANOTHER PILOT, WHO ALSO DID NOT HAVE ANY TIME IN TYPE, TO FLY WITH HIM ON THE INITIAL TEST FLIGHT AS THE PILOT-IN-COMMAND. AFTER PERFORMING SOME AIRWORK, THE SECOND PILOT THEN FLEW THE AIRPLANE TO A NEARBY AIRPORT FOR A LANDING.
