## Discrepancy

(YD5R)  WHILE COMPLING WITH A 500 HR INSPECTION, THE BRUSH HOLDER ASSY WAS REMOVED FOR INSP OF BRUSHES.  IT WAS FOUND THAT (1) BRUSH HAD A BROKEN WIRE.  THE WIRE HAD PULLED AWAY FROM THE CONTACT BUTTON.  TT ON COMPONENT ONLY 30.0 HOURS.  IT WAS LIKELY CAUSED BY AN IMPROPER CRIMP OR SOLDIER JOINT DURING MFG.
