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 MOONEY M20F MADE A TAKEOFF AND AS THE PILOT TURNED CROSSWIND, HE EXPERIENCED A PARTIAL POWER LOSS. HE RETURNED FOR A LANDING AND THE ENGINE SMOOTHED OUT. HE MADE EXTENSIVE GROUND RUNS AND COULD NOT DUPLICATE THE PROBLEM. HOWEVER HE DID NOT HAVE MAINTENANCE PERSONNEL LOOK AT THE AIRCRAFT. ON THE SECOND TAKEOFF, HE AGAIN LOST POWER AND THIS TIME, MADE AN OFF AIRPORT LANDING IN A FIELD. EXAMINATION OF THE ENGINE REVEALED THAT THE SPARK PLUGS HAD SOOT ON THEM. THE FUEL INJECTOR SERVO, MANIFOLD, AND NOZZLES CHECKED OUT OK; HOWEVER, THE RUBBER INTAKE BOOT BETWEEN THE AIR FILTER AND THE FUEL SERVO WAS FOUND PARTIALLY COLLAPSED.
