ATA 2701

Part: SCREW — BACKED OUT (CONTROL WHEEL)

THE SCREW THAT HOLDS THE CONTROL WHEEL TO THE YOKE WAS FOUND TO BE BACKED OUT ON THE PILOTS WHEEL BY A .2500 TURN. WHEN THE SCREW BACKS OUT ENOUGH, IT FALLS OUT ALLOWING THE WHEEL TO ROTATE FREELY AROUND THE YOKE. THIS RESULTS IN NO FLIGHT CONTROL INPUT. PROBABLE CAUSE OF THE SCREW BACKING OUT IS THAT THE SCREW IS TO SHORT. THE MS24964-S59 SCREW IS 1.0937 INCH LONG WITH ONLY HALF A THREAD SHOWING THROUGH THE NUTPLATE.
