## Discrepancy

PN 41789-000, FORK, ATTACHES THE ACTUATOR TO THE MAIN GEAR RETRACTION ARM AND DOWNLOCK CABLE.  IT FAILED DURING A CYCLE WITH NO PREWARNING OF ANY KIND.  WE ARE ALWAYS DOING A WEEKLY CLEANING AND INSPECTION OF THE LANDING GEAR.  THE ONLY WAY TO FIND THIS POINT OF FAILURE IS TO REMOVE THE FORK AND MAGNIFY THE SHAFT.  THIS FORK IS THE PART THAT RECEIVES THE MOST STRESS DURING OPERATION.
