## Discrepancy

DURING THE SCHEDULED REPLACEMENT OF THE STAB ACTUATOR, IT WAS NOTICED THAT THE ENTIRE HORIZONTAL STABILIZER HAD VERTICAL PLAY.  UPON FURTHER INVESTIGATION, IT WAS NOTED THAT THE L/H BUSHING INNER LINER HAD DISBONDED AND COMPLETELY WORKED ITSELF OUT OF THE BUSHING AND WAS IN THE CENTER SECTION OF THE PRIMARY BOLT.  I HAVE E-MAILED SEVERAL PICTURES AND A VIDEO OF THE MOVEMENT OF THE HORIZONTAL STAB.
