## 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.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Overrun, landing
  - speed brakes - improper use of, pilot in command (cause)
  - reversers - improper use of, pilot in command (cause)
  - procedures/directives - improper use of, pilot in command (cause)
  - airport facilities,runway/landing area condition - downhill (contributing factor)
  - airspeed(vref) - not maintained, pilot in command (cause)
  - weather condition - tailwind (contributing factor)
  - airport facilities,runway/landing area condition - wet (contributing factor)

## Analysis

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.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
