## Discrepancy

NOSE GEAR OPERATED NORMALLY ON JACKS.  WHEN SPRING PRESSURE WAS REMOVED FROM UPLOCK ACTUATOR ARM, A LARGE AMOUNT OF PLAY WAS NOTED IN THE LEFT SIDE CAM AND SHAFT, AND THE ARM COULD BE ROTATED INSIDE THE SHAFT 15 DEGREES EITHER WAY.  THE ARM WAS REMOVED FROM THE SHAFT, AND A CRACK RUNNING ALMOST THE FULL CIRCUMFERENCE OF THE ARM WAS FOUND AT THE ARM ATTACHMENT HOLE.  THIS CRACK COULD ONLY BE SEEN WITH THE UPLOCK ACTUATOR ARM REMOVED, OR FELT WITH THE SPRING TENSION REMOVED.
