## Discrepancy

WHILE COMPLETING AN ANNUAL INSPECTION.  ONE OF THE CYLINDER RET BASE NUTS FOR THE NR 4 CYLINDER WAS MISSING.  NUT WAS FOUND BETWEEN CYLINDER.  TORQUE CHECK MADE OF THE OTHER NUTS FOUND 3 MORE LOOSE.  WE CHECKED THE OTHER CYLINDER AND FOUND THEN TO BE OK.  ALL OF THE CYLINDER NUT DID HAVE INSPECTION TORQUE SEAL ON THEM.  THIS ENG BUILD DATA WAS 2/6/02. NO RECORD OF  CYLINDER WORK COMPLETED ON THIS ENGINE.
