Aircraft Accident/Incident Report

Teterboro, New Jersey 07608

NTSB Narrative Summary Released at Completion of Accident

After pretakeoff checks revealed no anomalies, the pilots taxied the airplane to the runway for takeoff. Shortly after beginning the takeoff roll, they received an aural warning, and the nosegear steering disconnect light illuminated on the master caution panel. The airplane veered left, and the pilots aborted the takeoff. The airplane’s nose landing gear and left main landing gear exited the left side of the runway, where the airplane came to rest undamaged. During postincident maintenance and troubleshooting, the airplane’s nosewheel steering computer was replaced, and subsequent taxi tests confirmed normal operation of the steering. The removed nosewheel steering computer was sent to the manufacturer’s facility for further testing, where it performed within specifications. The unit’s history log indicated repeated attempts to calibrate the unit and ultimately a failure of the strut servo. However, the failure could not be replicated in postincident tests.

NTSB Probable Cause Narrative

Failure of the nosewheel steering computer strut servo for reasons that could not be determined or replicated during postincident testing.
