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 CLIMBING UP TO AND LEVELING OFF AT 37,000 FEET, THE CREW OF THE DC-10-30F NOTICED THAT THE YORK CONTROL OF THE CAPTAIN AND THE FIRST OFFICER MOVED LATERALLY INDEPENDENTLY OF EACH OTHER FOR APPROXIMATELY TWO INCHES. AFTER MAKING AN UNSCHEDULED UNEVENTFUL LANDING AT DULLES THE LEFT AILERON CABLE TENSION REGULATOR ASSEMBLY WAS FOUND TO HAVE A DECREASE IN CABLE TENSION. AFTER LUBRICATION, THE UNIT JUMPED TO A POSITION WHICH PROVIDED PROPER CABLE TENSION BETWEEN THE CONTROL WHEEL AND THE AILERON CONTROL LOOP. THE OPERATOR CHANGED THEIR LUBRICATION PROGRAM ON THE ASSEMBLIES FROM 'ON CONDITION' TO EVERY 2500 HOURS WHICH EQUATES TO MORE THAN ONCE A YEAR.
