## Probable cause

THE CAPTAIN'S EXCESSIVE SPEED DURING A TURN OFF OF THE RUNWAY, AND HIS FAILURE TO MAINTAIN DIRECTIONAL CONTROL. THE WET TAXIWAY WAS A RELATED FACTOR.

## Sequence of events

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

- Loss of control - on ground/water, taxi - from landing
  - airport facilities,taxiway condition - wet (contributing factor)
  - taxispeed - excessive, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, taxi - from landing
  - terrain condition - soft

## Analysis

AFTER LANDING, THE FLT CREW INITIATED A 135 DEG TURN OFF OF THE RWY & ONTO A TWY. ACCORDING TO FDR DATA, THE TURN WAS INITIATED AT 38 KIAS. THE CAPT RPRTD THAT THE NOSEWHEEL STEERING BECAME UNRESPONSIVE ABOUT 2/3 OF THE WAY THRU THE TURN. THE NOSEWHEEL WENT OFF THE TWY & INTO DEEP MUD. NO PROBLEMS WERE FOUND WITH THE NOSEWHEEL STEERING OR BRAKES.
