## Discrepancy

UPON REPLACEMENT OF THRUST LEVER MODULE FOUND BOTH BOLTS ATTACHING THROTTLE CABLE CLEVIS TO THROTTLE MODULE CORRODED IN A HANK AREA WHERE BOLT PASSES THROUGH ROD END BEARINGS.  HAD TO DRIVE BOLTS OUT WITH PUNCH TO REMOVE.  UPON REMOVAL FOUND BOTH BOLTS DRY WITH NO VISIBLE LUBRICATION. ONE BOLT PITTED IN SHANK AREA.  ORDERED TWO NEW BOLTS FROM MANUFACTURER AND FOUND THAT NEITHER ORIGINAL BOLT WAS CORRECT SHANK LENGTH WHEN COMPARED WITH NEW BOLTS.
