Posted: Sun Feb 11, 2007 10:50 am Post subject: VS-1014 Question in Empennage |
|
|
After match drilling the holes of both VS-1014 with VS-1003 in the RV-10
empennage kit, I noticed that the last hole on each of the VS-1014 is too
close to the end. After countersinking, the edge of the counter sink hole
is at the end of the VS-1014.
I see three options, with the option two appearing to make the most sense to
me.
1. Leave it as is, but with the hole this close, I suspect this will
eventually crack and my cause a problem with the VS-1014 doubler down the
road.
2. Trim the VS-1014 a little shorter to remove this last hole. This would
shorten the piece about 1/4 inch.
3. There is always start over with a new part, but since this is a length
issue on a part that I didn't cut, I'm not sure I wouldn't end up in the
same boat again.
I can forward a picture if necessary.
What option would you recommend I take?
Thanks,
Bob

Bob,
Send me a photo and which page of the plans you are on and I'll try
to help you out. I can also send you some photos of my VS construction.

Are you referring to the top hole on each piece? If so, are you machine
countersinking the VS-1014 or the VS-1003. The hole that need to be
countersunk are the VS-1003 to accept a dimple in the skin for the head of
the 426AD3 rivet. If you countersunk the VS-1014, then I may recommend
getting it replaced and countersinking the hold on the spar with the new one
in place. If this is the case, then you should talk to Van's, but that part
can't be too expensive.
If you did countersink the hold in the VS-1003 and the countersink reaches
to the edge of the VS-1014, then I would recommend shortening it and using
an OOPS rivet in that hole because it is bigger because of the countersink
in the spar.
If you are talking about the bottom hole, then that shouldn't need a
countersink because that gets the 470AD3 rivet if I'm not mistaken.
If I am looking at the wrong part, then ignore this and give me an
electronic slap to straighten me up.
Do not archive.

It appears that my mistake was that I dimpled VS-1003 and VS-1001, then
counter sink VS-1014.
It has been brought to my attention that I should have not done anything to
VS-1014 and just counter sink VS1003 to accept the dimpled skin.
The question that I guess Van's will need to answer is can I just rivet
this, or will it require me to start fresh with new parts.

Just got off the phone with Gus at Van's. His opinion was just to proceed, since dimpling the VS-1003 and countersinking the VS-1014s doesn't weaken the structure.
He didn't think there would be an issue with the edge of the counter sink at the upper end of the VS-1014. But quickly added if that bothered me, just to add a doubler on the last two (top) holes to the VS-1014.
Boy, did I learn some lessons this weekend! Thanks to all that provided feedback.

That sounds fine. Gus is really a great guy to get on the phone. He knows
his stuff and is pleasant to talk to [unlike some other(s)]. That sounds
like a fine fix to me if Van's says it.
