## Discrepancy

COMPONENTS (LEVERS AND ASSOCIATED RODS) FOUND CORRODED.  NO CORROSION PREVENTATIVE MATERIAL FOUND ON PARTS.  CORROSION EXTENSIVE BUT ONLY ON THESE PARTS IN PARTICULAR.  SURROUNDING AREAS IN BETWEEN THE WHEEL WELLS APPEAR TO BE CLEAN AND FREE FROM CORROSION.  AFFECTED PARTS HAVE FLAKING WHITE POWDER BUILD UP AND DEEP PITTING ON THE ALUMINUM.  ROD ENDS HAVE RUST AND STIFF RESISTANCE TO ROTATION.  ATTACHING BOLTS AND COTTER PINS RUSTY AND PITTED WITH CORROSION.  DISCUSSION WITH TECHS SUGGEST THAT CLEANING AND LUBRICATION AS REQUIRED BY THE MM AND INSPECTION INTERVALS DOES MUCH TO ALLEVIATE THIS SITUATION.
