What was found
DURING A POST ENGINE MAINTENANCE GROUND RUN, THE PILOT COULD NOT MOVE THE CYCLIC IN THE AFT DIRECTION DURING THE HYDRAULIC SYSTEM CHECK. INSPECTION OF THE MAIN ROTOR CONTROL SYSTEM REVEALED THAT THE LONGITUDINAL ACTUATOR WAS AT THE FULL AFT TRAVEL LIMIT. WITH HYDRAULIC POWER REMOVED AND NO CYCLIC INPUT THE AFFECTED ACTUATOR WOULD MOVE TO THE CENTERED POSITION.
