 Posted: Thu Oct 01, 2009 5:05 pm Post subject: Another QB 10 Issue - Longeron Length (again) |
 |
|
Since I found some mid-fuse longerons that were too long, I thought I’d double check the primary ones that attach to the tailcone. Checking the lengths on those was something I never thought about doing.
Good thing I did – or so I think.
Attached is a photo of the right side longeron. The line in the photo is where I believe the longeron should be cut (49 23/32”) per 29-2 Step #1. As you can see, the longerons are more than 4” too long.
Which brings me to two interesting questions.
<![if !supportLists]>1) <![endif]>For those of you who have slow-built and not attached to the tailcone yet; How far do yours stick out past the side skin? Is my mark close to right?
<![if !supportLists]>2) <![endif]>I wonder how many other folks missed this step and now have an RV-10 QB’s with the tailcone and fwd fuse attached at the wrong point.

Phil,
If I read your measurements correctly, I think you’re spot on. My tailcone is mounted, but it was easy to measure since that longeron is on top and not covered by a skin. My measurement was 2-7/16”.

Thanks Bob…
I just threw the tape on there just to give you a sense of scale.
I went out and measured from the skins edge to the line and I’m 1/16” shorter than yours. I’ll add a 1/16th to it.
Just didn’t want to cut those things until I verified they really needed to be cut. That explains why they didn’t pre-drill those pilot holes for attachment too..
Thanks,
Phil

I had to trim the longeron, but not that much. I cut off about one inch or less. possibly my kit had shorter longerons to begin with.
