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.

WHILE THE ACFT WAS ON A X-COUNTRY FLT AT 4000 FT MSL, RADIO & RADAR CONTACT WERE LOST SOON AFTER A TURN WAS INITIATED. WRECKAGE OF THE AIRCRAFT WAS FOUND SCATTERED OVER A DISTANCE OF 2193 FT. AN EXAM OF THE WRECKAGE REVEALED THAT THE STABILIZERS/RUDDERVATORS, TAIL CONE, RIGHT WING & BOTH TIP TANKS HAD SEPARATED IN FLT. EVIDENCE OF DOWNWARD BENDING WAS FOUND ON BOTH RUDDERVATORS. EVIDENCE OF BOTH UPWARD BENDING & DOWNWARD BENDING WAS FOUND IN THE WINGS. THE INBOARD & OUTBOARD SECTIONS OF THE RIGHT WING HAD SEPARATED AS WELL AS ITS AILERON. THE ACFT GROSS WT WAS ESTIMATED TO BE NEAR ITS MAX LIMIT & THE CG WAS APRX 5.1 INCHES BEHIND ITS AFT LIMIT. THE CONTROL YOKE WAS FOUND POSITIONED TO THE RIGHT SIDE OF THE COCKPIT. THE PLT OF AN AIR FORCE ACFT REPORTED AN OVERCAST SKY CONDITION IN THAT AREA AT 1500 FT. A TEARDOWN OF THE ATTITUDE INDICATOR REVEALED SCRAPE MARKS ON THE GYRO & INSIDE THE CASE NEXT TO THE GYRO.
