Probable cause
The uncommanded left deflection of the airplane's nose wheel due to a malfunction of the electrohydraulic servo valve (EHSV) within the nose wheel steering manifold assembly. The reason for the malfunction could not be determined; however, a foreign substance was found between the armature and coil of the EHSV that once removed improved the performance of the unit. It is unknown how the foreign substance was introduced to this location.
