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.
Cordova, AK
DURING A LANDING AT NIGHT, THE ACFT TOUCHED DOWN SLIGHTLY LEFT OF THE RWY CENTERLINE, WHICH WAS NOT VISIBLE, & BEGAN VEERING TO THE LEFT. THE PLT REPORTED THAT THE ACFT DID NOT RESPOND TO RUDDER INPUTS, RUDDER TILLER INPUTS OR DIFFERENTIAL REVERSE THRUST. IT CONTINUED TO THE LEFT, HIT A 30 INCH SNOW BERM (LOCATED INSIDE THE RWY LIGHTS) & WENT OFF THE RWY. THE LEFT GEAR COLLAPSED & THE LEFT PROP HIT THE GROUND BEFORE THE ACFT CAME TO REST. DURING AN EXAM, THE LEFT WHEEL ROTATED FREELY, BUT ONE SIDE OF THE WHEEL WAS CUT & SCRAPED, INDICATING IT HAD BEEN LOCKED. NO MECHANICAL BRAKE MALFUNCTION OR FAILURE WAS VERIFIED. THIS WAS THE PLT'S 1ST FLT IN 21 DAYS.
