## Discrepancy

(CAN) PROBLEMS WITH RUDDER PEDAL ADJUSTMENT VERY STIFF. WHEN THE PIVOT ARM IS REMOVED FROM THE SUPPORT TUBE WE ARE FINDING CONTAMINATION ON BOTH PARTS. IT LOOKS LIKE SOME SORT OF ANTI CORROSION COMPOUND THAT HAS MIGRATED AND MAKES THE ASSY VERY STIFF TO OPERATE.  RUDDER PEDAL SUPPORT TUBE AND PIVOT ARM CLEANED.
