Posted: Thu Sep 10, 2009 10:38 am Post subject: QB Fuse Question

Last night, my QB fuse was delivered.  It’s been a long wait and I’m excited to get started again.  

   

I haven’t removed the floors yet, but hopefully I’ll get started on that later today after I’ve finished the inventory.  

   

It’s pretty obvious that every floor board needs to come out.   My question is specific to the forward most floor boards.  

   

The Landing Gear mount has a leg that goes forward and the foot is attached to the floor with some bolts.  I’m 99% sure that I need to remove this floor board, but it looks like I have to remove the landing gear mount to do so.  This contradicts their intent, because the landing gear mount is already torque’d to the center section carry-thru and the nuts are sealed with Torque Seal.  

   

I can’t imagine them going through the trouble to torque the nuts and apply Torque Seal if they wanted you to remove the landing gear – so you could ultimately remove the forward floor board.  

   

What have others done?  Is it possible to pull the forward floor board without removing the landing gear mount?

I pulled mine.  Found some clecos, a couple 12" drill bits,

and I think a pliers or some sort of tool under there.

If you can be assured that yours has no "stuff" under it,

and you don't intend to insulate, you could probably leave

them.  I put in 3/4" foam to dampen the sounds coming

off the engine.

I did not pull mine, but ran a magnet and vacuumed it well.

I was able to vacuum that area by using a piece of soft 1" hose as an extension on my shop vac. It is also possible to insert insulation from the aft edge of the floor boards, sliding each piece forward. It helps if you have small hands. Use the rivet lines on the bottom of the fuselage to make a pattern for each piece of insulation.

I pulled the left one and was sorry I did. It was a very difficult job and I was concerned that I was going to damage something the entire time. I decided not to remove the right side for that reason. You do have to remove the fasteners from the gear weldment. I felt as if I was undoing work I had paid to have done. Van's does not intend for the builder to remove the front floors on the QB.

Sounds like the consensus is to leave it in....



It sure would have been nice if they installed the right rivets to begin

with.  



They just have a couple dome headed pop-rivets in the dimpled holes to

hold the panels in place.  Sounds like I've got a pretty good chance of

having some rivet tails floating around between the belly skin and the

floor board.



That's a little concerning since it could contribute to a control

surface jam later on.



I'm sure I'll figure it out, just like all the folks before me.....

Thanks again everyone.



Phil

Sounds like maybe I was in the minority. I removed the forward floorboards (yes it is a pain to get the gear mounts out) but I am glad I was able to inspect C prime C insulate.  My motivation was to eliminate any little voice in my head in my flying future reminding me I had not inspected every inch of the airframe.

On my buddies -10 (mine is a slow build) we pulled them, cleaned and  

primed underneath them, installed insulation, then riveted them back  

in.  It really does not tale very long to remove the bolts.....

No front or rear floor rivet debris could cause a control jam; the controls

are not near these areas at all.

I did not remove the front floor boards either, but worry that there might be some stuff down there. If I were building over again, I would nut plate the rear floorboards for inspection/maintenance and smuggling drugs.



Seriously though, at the very least I would install a maintenance plate over the boarding step bolts. (I did do that)

I did not pull them. Used a strong magnet to move any metal stuff where it can be removed, and vacuumed. For insulation, I used Abesco FP200 fire rated expansion foam. I like it so much I'm thinking about using it in other places.

I started to do the same and decided to stop..."I felt as if I was 

undoing work I had paid to have done".  Even more important, the work I 

could see looked as good or better than what I was doing.  I moved on.



May have been a more critical issue for the earlier serials

Aluminum is non magnetic; strong magnet only moves ferrous metals. A thin

nylon tube tape to the end of a shop vacuum line may get some.

I had QB fuselage #8 dated 3/2005 and the work was excellent. Filipinos are

by far the best craftsman as a whole in the Asian sub continent.
