regarding the hardware securing the control surfaces it appears that only the flaps (-9 anyway) use castle nuts and cotter pins to secure the bolts. The ailerons, elevator and rudder use AN lock nuts. I recall that all control surfaces on a Cessna use castle nuts and cotter pins.
Are locknuts equally secure as the castelated nut and cotter pin? Is anyone substituting castle nuts w/ cotter pins in these locations; or even (presumably) better locking castle nuts w/ cotter pins?
It seems these lock nuts will be on/off numerous times before this thing flies. Do builders typically go through the whole plane and install all new locknuts nearing final inspection / first flight?
