Probable cause

The mechanical failure of the airplane's nose wheel/gear steering system. A contributing factor was the pilot's inability to maintain directional control following the loss of steering effectiveness.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

During landing rollout the pilot lost directional control of the airplane. The airplane veered off the runway and collided with bushes and a storm drain. The pilot reported that all systems had operated normally earlier in the flight. The reason for the mechanical failure of the nose wheel/gear steering system was not established.
