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.

AFTER SPRAYING 2 FIELDS, THE PLT WAS EN ROUTE TO SPRAY A 3RD FIELD WHEN A SEVERE VIBRATION OF THE ACFT WAS ENCOUNTERED. HE ELECTED TO LAND IN THE 1ST AVAILABLE FIELD & DUMPED HIS CHEMICAL LOAD. DURING THE LANDING, THE ACFT HIT A TERRACE & NOSED OVER. THE PLT STATED THAT HE DID NOT REALIZE THE FIELD WAS UNEVEN & TERRACED UNTIL THE ACFT WAS ON THE GROUND. GRASS & TALL WEEDS WERE GROWING IN THE FIELD. AN INVESTIGATION REVEALED THAT THE UPPER RIGHT ENG MOUNT HAD FAILED. NO FATIGUE WAS FOUND; HOWEVER, THERE WAS EVIDENCE OF HAMMERING, INDICATING MULTIPLE IMPACTS AFTER THE INITIAL FAILURE.
