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 PILOT WAS FLYING THREE PASSENGERS TO RAPID CITY FOR A SCHOLARSHIP INTERVIEW. HE RECEIVED A WEATHER BRIEFING PRIOR TO DEPARTURE & AGAIN EN ROUTE, BOTH TIMES RECEIVING INFORMATION ABOUT LIGHT TO MODERATE ICING CONDITIONS AT HIS DESTINATION. THE PLT REPORTED HE WAS IN ICING CONDITIONS AS HE TURNED TO INTERCEPT THE ILS LOCALIZER. HE THEN RADIOED THAT THE ACFT WAS IN A 'A SPIN AND A DIVE.' AN ON-SCENE EXAM REVEALED NUMEROUS LARGE PIECES OF CONTOURED ICE THAT MATCHED THE ROUNDED PORTION OF THE WING LEADING EDGE.
IMPROPER PLANNING/DECISION BY THE PILOT, ACCUMULATION OF STRUCTURAL ICE AND THE PILOT'S FAILURE TO MAINTAIN CONTROL OF THE AIRCRAFT. THE ADVERRSE WEATHER WAS A RELATED FACTOR.
