Probable cause
The improper installation of the nose steering actuator arming valve by a mechanic which resulted in failure of the actuator and on ground loss of directional control by the pilot during landing rollout.
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
Acft made sharp right turn and departed runway when nose steering was activated during landing rollout. Post accident investigation revealed the nose steering actuator had malfunctioned. The unit's arming valve was backed out and not secured by a required set screw. The seats for the valve were the incorrect seats. These two findings caused the actuator to have internal leakage which resulted in failure of the actuator. Logbook records indicated the arming valve was changed by a mechanic in the field in September 1988, 401 flt hours before the accident. In April 1989, fairchild aircraft issued a service bulletin that required the actuator be returned to the manufacturer for replacement of the arming valve.
