What was found
(CAN) ONE SCREW HOLE HAS 2 QUARTER INCH CRACKS RADIATING OUT BUT STOPPING BEFORE REACHING PART EDGE. PROBLEM FOUND FROM NDT TESTING FOR THE 1000 HOUR REQUIREMENT IN MM FOR ELEVATOR TORQUE TUBES. THIS PART IS MADE OUT OF MAGNESIUM, IF MANUFACTURER WOULD CHANGE PART MATERIAL TO ALUMINUM WE BELIEVE THIS WOULD SOLVE THE PROBLEM.
