## Discrepancy

(CAN) INDICATOR FOUND TO BE ROTATED IN TAIL ROTOR GEARBOX HOUSING. SIGHT GLASS REMOVED AND INDICATOR FOUND INSTALLED UPSIDE DOWN. UPSIDE DOWN INSTALLATION OCCURRED AT OVERHAUL OF TAIL ROTOR GEARBOX. UPSIDE DOWN INSTALLATION OF INDICATOR NEGATES THE LOCKING MECHANISM WHICH MAINTAINS THE CORRECT ORIENTATION OF THE INDICATOR. INDICATOR REMOVED, INSPECTED AND REINSTALLED SERVICEABLE. OVERHAUL FACILITY WAS NOTIFIED OF THE PROBLEM. (TC# 20190726010)
