## Discrepancy

(CAN) WHILE CARRYING OUT TASK CARD DH4-000-05-260-700, WIRE 2421-10067C-20 WAS FOUND BADLY CHAFED WITH EVIDENCE OF ARCING.  INVESTIGATION REVEALED THAT THE WIRE WAS CHAFING ON A RIB WHICH IS PART OF THE STRUCTURE OF PANEL HT262. WITH PANEL 262HT INSTALLED THE RIB CONTACTS THE ADJACENT WIRE BUNDLE.  THE CONDITION CANNOT BE OBSERVED WITH THE PANEL IN PLACE.
