Empennage Fairing Attachment

[Larry Ocker]

Dwg 44 empennage fairing attachment: Read and understand this drawing before you begin the fuselage, it will save you a lot of heartache. Especially the installation of the 2 F-794A empennage gap covers and the F-794B emppennage fairing. Platenuts have to be installed in the VS where the rivets were left out and in the HS where the rivets were not left out. The longeron has to be tapped for 6/32 screws where rivets were installed to fasten the F-773-L&R skin. Platenuts have to be installed in the F709 bulkhead where rivets were installed to fasten the F-775 rear top skin.

On Dwg 28 the fuselage skin rivet call out, all the holes are shown with rivets in them.

I know you should be familiar with all aspects of the construction process but some days it really irritates me with the lack of instructions.

You would think that $25,000 to $30,000 would buy you better instuctions. I found none for this procedure.

OK, I'm done venting.

I just hope I have helped someone else.

Larry,
I wish you had told me this last year.
I overlooked the "Leave These Rivets Out" and six months late when drilling between the existing rivets for the fairings nutplates, drilled throught the AL Angle spar reinforement in the stab.
I had to open the stab and replace it.

If you haven't done the left elev yet, read the whole thing first.
One para says, "dimple all the holes." I did.
The next para says, "Except........" Bummer, to late.

Taught me to read ahead.
Pete.

Man I have to agree with you guys, this whole area stinks! Now that I screwed up in all the places you all mention I find this post!

What prompted me to do the search is this... I can't figure out if the screws that attach the "B" fairing (#6 screws) just sit in the countersunk fiberglass or get washers of some kind? Seems to me that the small screws would just pull through the glass pretty quickly.

What do you all suggest or have you done?

BTW Larry, if you ever get close to Highland look me up, Wick's knows my address.

Thanks, Larry

We used countersunk washers, sometimes called 'tinnerman' washers. Spruce sells 'em,

Just to throw a twist on you guys. Heres what I did.

I think the Tinnermans are is a good solution. Hey Jeff great photos, thanks, neat fairing solution too.

A simple solution is to attach the gap covers with pop rivets. Unless you have a major trim issue, they will never need to be removed.

Thanks for the heads up to look at drawing #44 before riveting on the top aft skins.

So where are the F-795A empennage fairing parts. I don't seem to have them. Nor do I see them in the kit's inventory lists. Did you guys get them in the kit or make them, or order them?

thanks

Exactly what I did and it works great. Keeps you from messing things up when you remove the fairing.

Bill,
Do you remember the thickness of aluminum? I will be fitting mine in couple days and I like the solution.
