## Discrepancy

WHILE PERFORMING ELECTRICAL TROUBLESHOOTING FOR THE RUDDER WIRING, RUDDER COUNTERWEIGHT ATTACH RIVETS WERE EITHER WORN THROUGH THE MOUNTING BRACKET OR MISSING.  ONLY 1 OF THE 8 ATTACH RIVETS WAS ENGAGED IN THE COUNTERWEIGHT.  SEIZURE OF THE RUDDER ASSY COULD OCCUR SHOULD THE COUNTERWEIGHT BECOME DETACHED.
