Mar 31, 2024 1 Drilling emp fairing to tailcone Category: Empennage
I don't really care for the Van's instructions on drilling through the opaque fairing. They have you drill a #40 hole, tape a powerful magnet in the hole, put the fairing back on, put another powerful magnet over a washer and then let the magnet seek the other one. OK, I guess. It worked OK on the spinner, but why? There's a reference line on the tape, you know the hole has to be about 1/4" aft of that line, so you can just transfer that line onto the fairing and drill.

I didn't do that because somewhere in my youth I was taught to follow directions. In this case, I wish I hadn't because the hole in the fairing was off. Not by much but somewhere in my youth I became kind of OCD. In the end, it probably won't matter because the hole is going to get enlarged to a #27 and, besides, there's going to be a nutplate here doing all the work.

The next hole they tell you to drill is the inboard hole on the bottom fairing - both of these on the left side. So this time I did what I just said I should have done. It still didn't come out exactly where I wanted -- a little too forward but a nutplate will fit in there.

Now, I have to get some help to wrestle the stabilator back on to check for clearances.
