## Discrepancy

(CAN) DURING THE COURSE OF A COMPASS SWING ON A/C, THE RT WING TIP WAS REMOVED TO ADJUST THE FLUX VALVE.  AT THIS TIME IT WAS NOTICED THAT THE RT AILERON OUTBOARD BALANCE HORN WEIGHT WAS CRACKED THROUGH THE ATTACHMENT HOLES APPROXIMATELY 90 PERCENT OF THE WAY THROUGH.  UPON REMOVAL NUMEROUS OTHER CRACKS WERE FOUND RADIATING OUT FROM THE ATTACHMENT HOLES.  THE PART WAS REPLACED AND ALL THE OTHER WEIGHTS WERE CHECKED WITH NO DISCREPANCIES FOUND.
