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.

ACCORDING TO CONTINENTAL AIRLINES, THE CAPTAIN EXECUTED AN ILS APPROACH TO RUNWAY 11 AND USED AN AIRSPEED (V REF) OF 136 KNOTS. THE FLIGHT DATA RECORDER REVEALED THAT THE AIRSPEED FLUCTUATED FROM 150 KNOTS TO 159 KNOTS DURING THE FINAL PHASE OF THE APPROACH. THE AIRPLANE TOUCHED DOWN ABOUT 2500 FEET DOWN THE WET, DOWNHILL RUNWAY. THE CAPTAIN STATED THAT HE DEPLOYED THE THRUST REVERSERS, AND THEN THE SPEED BRAKES. THE PROCEDURE TAUGHT TO CONTINENTAL PILOTS WAS TO DEPLOY THE SPEED BRAKES FIRST, AND THEN THE THRUST REVERSERS IN ORDER TO PRODUCE MAXIMUM BRAKING EFFECTIVENESS. THE AIRPLANE OVERRAN THE RUNWAY.
NTSB Probable Cause
THE PILOT IN COMMAND'S EXCESSIVE AIRSPEED DURING APPROACH, AND HIS FAILURE TO FOLLOW THE PROPER BRAKING PROCEDURES DURING LANDING AS PER COMPANY TRAINING. FACTORS CONTRIBUTING TO THE ACCIDENT INCLUDE A TAILWIND AND A WET, DOWNHILL RUNWAY.
