## Discrepancy

DURING RETURN FLIGHT TO BASE, CREW SMELLED A HOT BRAKE BURNING SMELL, THEN IT QUICKLY DISSIPATED.  NO OTHER INDICATIONS WERE NOTED.  PILOT SEEMED TO FEEL A LIGHT AMOUNT OF RESISTANCE ON CYCLIC CONTROL.  LANDED BACK AT BASE WITH NO ISSUE AND CALLED MECHANIC TO PERFORM INSPECTION.  NO PHYSICAL PROBLEMS WERE FOUND AND COULD NOT DUPLICATE ON GROUND RUN.
