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.

DURING A NIGHT TIME VOR/DME APPROACH FOR LANDING IN FOGGY CONDITIONS, THE AIRPLANE COLLIDED WITH A FIFTEEN FOOT HIGH MOVEABLE IRRIGATION SYSTEM LOCATED IN AN OPEN FIELD APPROXIMATELY TWO AND A HALF MILES EAST OF THE AIRPORT. RADAR DATA INDICATES THAT THE FLIGHT WAS ESTABLISHED ON THE APPROACH AND AT A PROPER ALTITUDE AT THE FINAL APPROACH FIX. TWO RADAR TARGETS AFTER THE FIX INDICATE THAT THE FLIGHT DESCENDED BELOW THE PUBLISHED MINIMUM ALTITUDE AND COLLIDED WITH THE IRRIGATION SYSTEM. POST CRASH INSPECTION DID NOT REVEAL ANY MECHANICAL FAILURES OR MALFUNCTIONS.

NTSB Probable Cause
