This has nothing to do with the model As but it is food for thought. Helicopters are currently required to have two locking features on all control system linkage hardware. Many use a locking castle nut with a cotter pin and some use a locking nut with safety wire. The Robinson types used steel locking nuts with a pall nut. That always reminds me of my late Mercury 8CM flatheads V8s that used a pall nut on the connecting rod bolts. They likely didn't need them but I always put them back on there during an overhaul.
