## Discrepancy

(CAN) AFTER REPLACEMENT OF DISPLACEMENT GYRO, FLIGHT CREW NOTIFIED MAINTENANCE THAT THE ATTITUDE INDICATOR INFORMATION WAS BACKWARDS.  MAINTENANCE FOUND THE FORWARD POINTING ARROW ON THE COVER OF THE UNIT WAS INSTALLED BACKWARDS.  THIS ARROW IS TO GUIDE THE INSTALLER OF DIRECTION OF FLIGHT.  THE REPAIR FACILITY WAS NOTIFIED OF THE ISSUE.
