What was found
DURING ANNUAL INSPECTION, TORQUE TUBE ADAPTER ON THE LEFT ELEVATOR DISCOVERED LOOSE AND WORKING. A BALANCE CHECK OF THE ELEVATORS REVEALED THEM TO BE CLOSE TO THEIR LIMITS, BUT STILL SERVICEABLE. LEFT ELEVATOR WAS UNDER BALANCED AT 17.5 INCHES/POUNDS. ITS LIMITS ARE 0.0 TO 18.5 INCH/POUNDS. THE RIGHT ELEVATOR WAS UNDER BALANCED AT 24 INCHES/POUNDS. ITS LIMITS ARE 0.0 TO 24.5 INCH/POUNDS. RECOMMEND TIGHTER LIMITS ON CONTROL SURFACE AND MORE FREQUENT CHECKS OF CONTROL SURFACE BALANCE.
