## Discrepancy

DURING 500 HOUR INSPECTION AND REMOVAL OF T/R SERVO OVERCENTERING  MECHANISM, IT WAS DISCOVERED THAT THE MAIN SUPPORT BOLT AND THE BELLCRANK PIVOT BOLT WERE VERY DIFFICULT TO REMOVE.   THE BELLCRANK PIVOT BOLT WAS OBVIOUSLY HAMMERED IN BY EVIDENCE OF THE RAISED METAL AND ELONGATED HOLE.  REPLACED BELLCRANK AND BOTH BOLTS.  (K)
