What was found
SEVERELY CORRODED MAGNESIUM BELLCRANK WHICH OPERATES THE BIAS BUNGEE FOR ELEVATOR TO STABILIZER LONGITUDINAL CONTROL. THIS UNIT IS LOCATED IN THE AFT LOWER LEFT SIDE OF FS 457. VISUAL INSPECTION IS VERY DIFFICULT DUE TO LOCATION AND POSITION OF ROD END ATTACHMENT POINTS. SUBMITTER SUGGESTS THIS ITEM BE REMOVED AND INSPECTED AT NEXT SCHEDULED INSPECTION. BELLCRANKS FAILURE WOULD CAUSE LIMITED ELEVATOR TRAVEL AND LOSS OF ELEVATOR TO STABILIZER CONTROL FOR TRIMMING.
