I know this was brought up before, but where can I find some? I have looked at Aircraft Spruce and Wicks.
Thanks, Bob Newell

I am looking to replace the bolts with new ones. They are listed in the manual as part number
0431141 Bolt - Elevator Bell Crank Stop. I didn’t see them at Aircraft Spruce or Wicks.
Thanks, Bob Newell

Winner Aviation in Niles, OH has 0431141-1. I found them doing a part number search on Controller.com.

Not sure what the dash 1 is, but might be worth a call to them.

Are they 10-32 bolts? If so, I have an NAS428 stop bolt that works for the ailerons and should work there, too, except you may have to shorten them. They are 1-1/4" long and threaded over the whole length of the bolt.

Thanks Larry and John, I haven’t had time to check on them yet. I should be able to look into it next week.

I checked the parts catalog and they screw into a 10-32 nut, so the ones I have should work, unless the heads drilled for safety wire.

They’re made from an AN3H-11A bolt with threads cut most of the way up the shank. The -1 is the same except made from an AN3H-15A. There is also a -2 and a -4, same but even longer AN bolts.

Stop bolts have no raised markings on the head. Also, if Cessna is making them from AN hardware, then I'm guessing they're re-plating them after.

I'm sure they were, have to justify them being so expensive somehow!

The -1 bolt does supersede to a NAS428H3A12 on the textron website.

How fortuitous! The very one I have. (Shameless plug...)
