## Discrepancy

TAIL ROTOR GEARBOX CHIP LIGHT INDICATION IN FLIGHT. PRECAUTIONARY LANDING WAS PERFORMED AS PER THE RFM. THE MECHANIC ARRIVED TO INSPECT THE AIRCRAFT AND FOUND ONE HAIR-LIKE PARTICLE ON CHIP DETECTOR. CLEANED AND REINSTALLED DETECTOR. A TEN MINUTE GROUND RUN WAS PERFORMED AS A PRECAUTION WITH NO FURTHER DEFECTS FOUND.
