## Discrepancy

WHILE COMPLYING WITH AD 11-07-13 LT AND RT ELEVATOR SPAR, IT WAS NOTED THAT THE HORIZONTAL STAB WAS LOOSE AT BOTH THE FRONT AND REAR MOUNTING POINTS.  MOVEMENT WAS MOST NOTED AT THE FWD PORTION OF THE STAB WITH A ROCKING MOVEMENT SIDE TO SIDE.  UPON INVESTIGATION IT WAS FOUND THAT ALL 10 BOLTS WERE TURNED A COMPLETE REVOLUTION TO TORQUE.  REMOVED BOLTS AND EXAMINED HOLES FOR ELONGATION AND DAMAGE.  NONE NOTED.  TORQUED BOLTS TO FACTORY RECOMMENDED TORQUE VALVES.  RECOMMENDED THAT THIS TORQUE VALVE BE CHECKED IMMEDIATELY, AND AT YEARLY INSPECTION.  LOG BOOK RESEARCH SHOW THAT BY RECORD NO WORK HAD BEEN DONE TO EITHER THE HORIZONATAL OR TO THE VERTICAL FIN.
