## Discrepancy

DURING DAILY INSP, THE THRUSTER ASSY SYSTEM WAS OPERATED TO CHECK THE OPERATION AND SMOOTHNESS OF THIS SYSTEM.  A LOUD NOISE WAS HEARD AND THE THRUSTER CONE WAS DISCONNECTED FROM THE CONTROL SYSTEM.  UPON REMOVING THE TAILBOOM FAIRING TO GET ACCESS TO THE INTERCONNECT CABLES, CLOSER LOOK AT THIS CABLE END AND IT APPEARS THAT THE CABLE END HAS CORROSION FROM THE INSIDE OUT.  REQUESTED COPY OF METALLURGY TEST. (WP13200401531)
