## Probable cause

The uncommanded left deflection of the airplane's nose wheel likely due to seal deterioration and subsequent contamination within the Electrohydraulic Servo Valve (EHSV).  Contributing to the incident was the undersized condition of the filter plugs within the EHSV which likely caused the C2 orifice filter seal to extrude and deteriorate.
