Brief Description: Finished sanding and priming HS skeleton
Sanding and priming the horizontal stabilizer skeleton took all of Saturday and Sunday (1 hour of Friday evening). I had to fight the weather on Sunday as rain showers passed through during the morning. The bugs were also out zipping around and found their way onto a few of the parts.
While checking over the rear spar I noticed that the center bearing was installed inverted as compared to the way it had been match drilled. While installing the part on the bench I had flipped the spar outward to help with torquing the 4 nuts that secure the bearing. This caused the orientation to reverse, as compared to how it was originally match drilled, and I did not catch it until QA'ing the spar. It would probably not have made any difference as there is no up or down orientation on the bearing. It is a match drilled part and I wanted to keep the parts matched. So off come the 4 bolts and the bearing gets flipped.
The AN365-1032 nut is a nylok that holds the center bearing bolts. I checked in my SportAir workshop manual and it states that the nut may be reused, if it cannot be finger tightned. Checked all four and they were good to go. Torque has been set to 24 in/lb and I have some torque seal (orange stuff) on order from Sky Geeks and will mark the nuts/bolts when it arrives.
I cleco'ed the front spar and reinforcing angles that join the two front spars together. Mondays plan of action is to begin riveting the forward spar and ribs.
