## Discrepancy

DURING CRUISE FLIGHT THE PILOT FELT THE CONTROLS GET "HARD" LIKE A HYDRAULIC SYSTEM FAILURE, BUT AIRCRAFT STILL FLYABLE.  PILOT OPTED TO DO PRECAUTIONARY LANDING IN AN OFF-AIRPORT AREA WITH NO INCIDENT REGARDING PERSONNEL OR AIRCRAFT.  AFTER INSPECTING SYSTEM FOUND HYDRAULIC CUTOFF SWITCH ON PILOT'S COLLECTIVE TO BE INTERMITTENT AND PUTTING SYSTEM INTO BYPASS AND LOCKING THE CONTROL SERVOS.  AFTER REPLACING THE SWITCH THE AIRCRAFT OPERATED NORMALLY.
