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 MAIN CARGO DOOR OPENED IN FLIGHT AND THE AIRPLANE RETURNED FOR A NORMAL LANDING. OF THE TWO CIRCUIT BREAKERS REQUIRED TO BE PULLED PRIOR TO TAKEOFF, ONE WAS FOUND STILL ENGAGED. A CONFORMITY INSPECTION ON THE CARGO DOOR INSTALLATION REVEALED SEVERAL AREAS OF NONCONFORMITY INCLUDING DOOR LOCKS OF LESS THAN REQUIRED STRENGTH, LACK OF PAINT ON DOOR LOCKS WHICH IS USED FOR VISUAL IDENTIFICATION, AND DAMAGED WIRES IN A BUNDLE. THE WIRES WERE PART OF THE DOOR CLOSING, DOOR LOCKED INDICATING SYSTEM. THE INVESTIGATION REVEALED IT WAS POSSIBLE FOR THE DOOR TO BE NOT COMPLETELY CLOSED AND HAVE THE DOOR WARNING LIGHT GO OUT, INDICATING IT WAS FULLY LOCKED.
NTSB Probable Cause
THE FAILURE OF THE FLIGHT ENGINEER TO CONDUCT A PROPER PREFLIGHT INSPECTION AND ENSURE THE MAIN CARGO DOOR WAS FULLY CLOSED AND LOCKED. FACTORS RELATED TO THE ACCIDENT WERE THE DAMAGED WIRES IN THE BUNDLE, AND THE IMPROPER MAIN CARGO DOOR INSTALLATION.
