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 TAXIING FOR TAKEOFF, THE COPLT ATTEMPTED TO INCREASE THE PRESSURE IN THE LANDING GEAR DOWNLINE BY PLACING THE LANDING GEAR HYDRAULIC HANDLE IN THE DOWN POSITION. THE COPLT BELIEVED THAT HE CONFUSED THE PROCEDURE & PULLED UP ON THE LANDING GEAR LOCK HANDLE, RATHER THAN PUSHING THE GEAR HYDRAULIC HANDLE DOWN. THIS WOULD HAVE RELEASED THE GEAR MECHANICAL LOCKS. SHORTLY AFTER THAT, THE LEFT GEAR COLLAPSED. AT THE SAME TIME, HYDRAULIC FLUID & FUMES ENTERED THE COCKPIT. AN INVESTIGATION REVEALED THAT A HYDRAULIC LINE TO THE PRESSURE GAGE HAD FAILED FROM OVER PRESSURE.AFTER REPAIRING THE LINE, THE SYS WAS TESTED & OPERATED NORMALLY.
