Brief Description: Install Wings and NAS Close Tolerance Bolts
Re-installed wings for the last time. Installed the NAS 1304 and 1307 close tolerance bolts into the right- and left-wing spar box. First installed several drift pins using the hardware bolts with grinded end points. Though the drift pin bolts were easy to install after getting the wings position correctly, replacing these with the NAS close tolerance bolts required tapping the bolts into place. Used some bloelube on the bolt shafts to ease the process a bit. I installed the NAS 1307 bolts first, then the 1304 bolts. Thanks to Ken and Debbie for helping me out. I don't anticipate removing the wings again. Installed the requisite washers and nuts to allow for setting the proper torque. My first attempt resulted in a cracked nut because it ran out of thread - not at all obvious prior to the attempt. Added another full and light washer to ensure this would not reoccur, and torque leaving some thread showing for each bolt.
Installed the AN4 bolt on each rear wing spar, torqued and installed the cotter pin.
