## Discrepancy

PILOT REPORTED A TAIL ROTOR CHIP LIGHT DURING CRUISE FLIGHT.  IT FLICKERED AT FIRST, AND AFTER ABOUT 30 SECONDS CAME ON SOLID.  THE PILOT IMMEDIATELY DIVERTED TO THE CLOSEST AIRPORT.  ONCE SAFELY ON THE GROUND, HE CONTACTED MAINTENANCE.  THE MECHANIC ARRIVED AND INSPECTED THE CHIP DETECTOR, AND FOUND A FEW METAL SHAVINGS.  HE THEN CLEANED THE CHIP DETECTOR, AND FLUSHED THE TAIL ROTOR GEARBOX TWICE.  AFTER DRAINING, THE TRG OIL STILL HAD FERROUS AND NON-FERROUS MATERIAL.  NOTIFIED AIRBUS TECH REP AND RMD.  ORDERED A TRGB AOG.  THIS AIRCRAFT REMAINS OUT OF SERVIC AT THIS TIME, WHILE THE TRGB IS REPLACED.
