## Discrepancy

WHILE REPLACING A BROKEN GEAR ACTUATOR THE PIVOT WAS REMOVED AND INSPECTED.  A CRACK WAS FOUND IN THE LOWER RADIUS AT THE BOTTOM OF THE GEAR SPLINES.  TO PREVENT THIS PROBLEM IT IS SUGGESTED THAT THE MLG PIVOTS BE REMOVED FROM THE AIRCRAFT AND INSPECTED EVERY 1000 HOURS.  IT IS ALSO SUGGESTED THAT THE MFG OF THIS PART REDESIGN THE PART OUT OF STEEL.
