What was found
ENGINE FUEL CONTROL LINKAGE ATTACHING NUT HAS BACKED OUT. THIS HAS ACCURED FIVE TIMES IN THE PAST, ON DIFFERENT AIRFRAMES OPERATED. THE RESULT OF THE NUT BACKING OFF THE FUEL CONTROL ACTUATING SHAFT CAUSED A LOSS OF MANUAL CONTROL VIA THE POWER LEVER IN COCKPIT. THE A109E POWER CONTROL SYSTEM IS ONE OF A REDUNDENT NATURE , SO NO LOSS OF POWER WAS EXPERIENCED IN FLIGHT. THESE AIRCRAFT ARE NOT OPERATED IN CIVILIAN CATAGORY, AND THIS DISCREPENCY IS OF AN ISOLATED NATURE, WHICH HAS BEEN CORRECTED USING UPDATED INSPECTION METHODS LOCALLY.
