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.

AFTER COMPLETING A DUAL INSTRUCTIONAL FLT IN 91 TO 103 DEG WX, THE ACFT LANDED UNEVENTFULLY. THE PIC FAILED TO FOLLOW THE REQUIRED PROCEDURE IN THE FLIGHT MANUAL OF TURNING OFF THE ANTI-SKID SWITCH AFTER CLEARING THE RWY. RATHER, HE USED THE OUTDATED PROCEDURE IN AN OLD CHECKLIST CARD & LEFT THE ANTI-SKID SWITCH ON. AS THE PIC PARKED THE ACFT THE ANTI-SKID CONTROL UNIT MALFUNCTIONED & RELEASED BRAKE PRESSURE. BY THE TIME THE PIC REGAINED CONTROL BY ACTIVATING THE EMERGENCY PNEUMATIC BRAKE SYSTEM, THE ACFT HAD COLLIDED WITH A CESSNA 500 & AN AERO COMMANDER 500S. TWO YEARS EARLIER A SERVICE LETTER HAD BEEN ISSUED STATING THAT THE ANTI-SKID CONTROL UNIT COULD MALFUNCTION AT TEMPS OVER 100 DEG F. THE OPERATOR HAD FAILED TO COMPLY WITH THE SL & HAD NOT SUBMITTED THE UNIT FOR MODIFICATION. WITHIN THE PAST MONTH THE PIC & THE COMPANY CHIEF PLT HAD OBTAINED TYPE RATINGS IN THE ACFT FROM A DESIGNATED PLT EXAMINER.
