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 PILOTS WERE MAKING AN NDB APPROACH TO AN UNCONTROLLED AIRPORT THAT WAS 941 FEET MSL. THE NDB WAS 1.8 NM FROM THE AIRPORT, AND THE PILOTS WERE SUPPOSED TO MAINTAIN MINIMUM DESCENT ALTITUDE (MDA) OF 1,540 FEET UNTIL THE RUNWAY WAS IN SIGHT. PRIOR TO THE CRASH, ATC HAD TOLD THEM THAT THEY WERE 15 MILES FROM THE AIRPORT. APPROXIMATELY FOUR MILES FROM THE AIRPORT, THE AIRPLANE IMPACTED THE TOP OF A HILL, AT A POINT 990 FEET MSL. THE AIRPLANE WAS DEMOLISHED BY IMPACT AND POST-IMPACT FIRE. THE WEATHER WAS ESTIMATED TO BE 300 FEET OVERCAST AND ONE MILE VISIBILITY. NO MECHANICAL MALFUNCTIONS WERE REPORTED OR DISCOVERED. THE LACK OF A LOCAL ALTIMETER SETTING INCREASED THE MDA BY 240 FEET.
NTSB Probable Cause
IMPROPER IFR PROCEDURE BY THE PILOT BY NOT MAINTAINING THE MINIMUM DESCENT ALTITUDE (MDA) FOR THAT SEGMENT OF THE APPROACH. FACTORS RELATED TO THE ACCIDENT WERE: DARKNESS, LOW CEILING, FOG, AND RAIN.
