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.

RADAR DATA SHOWS THAT DURING AN ILS APPROACH TO RWY 5 OF THE COEUR D'ALENE AIRPORT, THE AIRPLANE WAS WELL ABOVE ALTITUDE. THE DESCENT PROFILE FOR THE APPROACH DEPICTS THAT AN AIRPLANE WOULD EXPECT TO CROSS THE OM AT 4,039 FT, AND CROSS THE MM AT 2,535 FT MSL. THE AIRPLANE'S ALTITUDE IN THE VICINITY OF THE VOR, MM, AND AIRPORT WAS BETWEEN 4,900 FT AND 5,100 FT MSL. THE AIRPLANE CONTINUED DESCENDING AFTER PASSING THE AIRPORT AND COLLIDED WITH THE PEAK OF A MOUNTAIN ABOUT 7 MI FROM THE AIRPORT 2 FT BELOW THE SUMMIT ELEVATION OF 3,395 FT MSL.
NTSB Probable Cause
THE PILOT'S IMPROPER IFR PROCEDURE IN FAILING TO INTERCEPT THE PROPER GLIDESLOPE PATH.
