Returned to the assembly today by beginning with the attachment of the horizontal stabilizer to the fuselage.
There are four AN4 bolts that need to be installed in the aft fuselage attachment bracket. The holes there now need to be enlarged to 1/4", so as I did with the forward mounting bracket holes, I plan to enlarge these four holes in a series of steps. I will final ream the hole to size; ensuring a quality fit.
