I can't find the torque setting for the AN924-4D nut that holds the bulkhead coupling on to the fuel tank end rib. I can find torque values for the nuts that hold the flared tubes to the coupling, but not the nut that hold the coupling to the bulkhead....
OK - I've figured out that it is a 7/16x20 thread, so the standard thread table calls for 450-500 in-lbs for a "standard" nut or 270-300 in-lbs for a "shear-type" nut. I wonder what kind of nut this is?
Thanks for any help,
