## Discrepancy

AFTER TAKEOFF, THE TAIL ROTOR CHIP LIGHT ILLUMINATED, AND THE PILOT WAS ABLE TO CLEAR THE LIGHT. THE PILOT THEN DIVERTED AND DECLARED AN EMERGENCY. BEFORE THE AIRCRAFT COULD REACH THE DIVERSION AIRPORT IT WAS DECIDED TO LAND IMMEDIATELY DUE TO PILOT FEELING VIBRATIONS COMING FROM TAIL ROTOR.  THE LANDING WAS COMPLETED IMMEDIATELY.
