## Discrepancy

(AUS) AFTER TAKE-OFF THE LG WAS SELECTED UP AND VIBRATION AND NOISE WAS HEARD DURING RETRACTION WITH EXTENDED WINDING TIME - RED HANDLE UNSAFE LIGHT REMAINED ON WHEN GEAR APPEARED TO BE UP. GROUND INVESTIGATION COULD NOT REPRODUCE THE PROBLEM. GEAR MICROSWITCHES WERE CHECKED FOR ADJUSTMENT/WEAR, AND THE NLG DRIVE CHAIN AND SPROCKETS WERE ALSO INSPECTED.
