## Discrepancy

(CAN) INTERMITTENT FAILURE.  AIRCRAFT DID NOT ARRIVE AT THE STATED POSITION. THE AUTOPILOT COMPENSATOR INDICATED FUNCTIONED NORMALLY, BUT THERE WAS NO MOVEMENT FROM THE HORIZONTAL STABILIZER WHICH CAUSED AN AUTO DISCONNECT OF THE AUTOPILOT SYSTEM.  THE TWO MOTORS ARE INSTALLED ON THE SAME TRANSMISSION, IT BECOMES IMPOSSIBLE IN THE EVENT OF BREAKING MECHANICALS TO ACTUATE THE COMPENSATOR.
