What was found
(CAN) WHILE DOING A TEE INSPECTION, HAD TO DISCONNECT THE INPUT LINKAGE TO THE M/R ROTOR SERVOS TO ACCOMPLISH A TASK. THEN NOTICED THAT THE BOLT THAT GOES TO THE PILOT VALVE WAS SMOKING. WHICH IN COMPARISON WITH THE OTHER TWO M/R SERVO`S THE AFFECTED BOLT WAS VERY FREE TO ROTATE AND A GOOD AMOUNT OF AXIAL PLAY AND RADIAL PLAY WAS NOTED. DECIDED TO REMOVE THE SERVO FROM SERVICE AND GET IT REPAIRED.
