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.

HOWEVER, THE SNOW ON THE RUNWAY WAS 6 INCHES THICK AND COVERED WITH A CRUST OF ICE. THE PILOT ELECTED TO LAND. AFTER TOUCHDOWN, THE PLANE CONTINUED NORMALLY FOR 75 TO 100 FT, THEN THE MAIN WHEELS BROKE THROUGH THE CRUST AND THE AIRCRAFT NOSED OVER. AN INVESTIGATION REVEALED THAT THE AIRPORT WAS UNMANAGED AND NO OFFICIAL OPERATIONS WERE CONDUCTED THERE DURING THE WINTER MONTHS. THEREFORE, NO NOTICE OF THE FIELD CONDITION WAS GIVEN TO THE FSS. SINCE THE FSS WAS UNAWARE OF THE EXTENT OF THE SNOW COVERING, NO NOTAM WAS ISSUED.
