In fact, he had JUST finished mounting the tail and was finalizing his trim tab settings when he got the SB. Sounds like the time involved is less than 4 hours for disassembly, and a little over 4 hours for re-assembly, and that the riveting itself is very easy. So you can plan on probably being able to tackle it in a 10 hour day or less if everything goes smoothly. I'm not sure exactly when I'll get mine done, but I'm hoping to make it relatively soon, so I'll report back too.

I don't believe that the diagram as previously reported is correct, as the flat version of the part would actually have two tabs at the outboard top edge. My understanding is that the crack would be in the tab that is riveted to the longeron. ________________________________ Message 11 ____________________________________ Time: 08:34:02 AM PST US From: Jesse Saint Subject: Re: RV10-List: SB Info My understanding from Ken Krueger is that the bulkhead is a little too thin and in the process of transferring the load from the HS to the rest of the structure it is flexing more than it should be, so the doubler helps limit the flexing to more effectively transfer the load to the rest of the structure (longerons, skins, etc.). I'd rather have rivets holding it on there than some other type of bond unless it were screws or bolts, since that is the way the plane it put together to start with. do not archive Jesse Saint Saint Aviation, Inc. jesse@saintaviation.com Cell: 352-427-0285 Fax: 815-377-3694 On Jun 11, 2008, at 10:58 AM, John Gonzalez wrote: > The thing that bothers my mind about this type of repair/doubler is > that the bulkhead is made of relatively thin material.

Using known materials and a reliable connector process applied in a specific way, we have a reliable fix. Though it's probably noteworthy that the same approach was taken with the original design that is now showing cracks (but no failures). I'm guessing that a flexible bonding method might be superior - but I have a difficult time thinking of how a reliable bonding process could be defined and followed reliably in my shop. Temperature, surface treatment and all that. I can deburr the parts and drive a dozen rivets to a spec. I'm never 100% sure my last epoxy job is to spec.

With rivets that are properly squeezed (read not excessively, which would stress the hole) I think the doubler would have enough holes spread out to diminish any one area except as a whole and in turn be a stronger solution than before adding it..

When the new HX displays are on the scene they will use USB directly to the Wx receiver (processor box not needed with the HX). Only ports 1 & 2 on the WS/HS support the 115,200 high speed serial rate. For redundancy there are some cases where a single device (like the AHRS/ADC) feeds multiple DUs. I'd be happy to email my connectivity and configuration documents to those interested. My panel config has the following so it's pretty complete starting point: GRT (3 screens) PMA-8000B SL-30 GNS-480 GTX-330 TruTrak Digiflight II-VSGV GRT Weather receiver/processor CO Guardian 353 AOA Pro It is a relatively minor wiring difference between the GNS-480 I'm using and a 430W and doesn't impact the serial port configuration.

What I had decided to do, but had not done yet, is to put a mirror image angle on the aft side of F-1010 like on the forward side. I would then have two angles with a total of four bolts to the longeron. Not knowing all the details of the fix, they seem to treating a symptom and not the cause. It seems that an additional angle would reduce twist and also strengthen the attachment. I am planning to do this in addition to Van's SB. I would like to hear what others think. In addition, I had already planned to add another angle at the aft portion of where the VS attaches to the tailcone.

That's a pretty hefty crack. Seems the crack will just be on the edge of the doubler if things are moving around that much. Antenna doublers are supposed to be secured along 3 sides. I'm wondering if the rib was "forced" into position possibly installed with a bit of a bending load on it? 2) The J-Channel is contacting the bulkhead... Didn't we just discuss this? 3) I won't mention the nice long, uniform scratches in the side skin. 4) Anyone know what the pop rivets in front of the F-1010 are.... data plate? 4) I'm with Dave... must be the Continental :-) -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of David McNeill Sent: Wednesday, June 11, 2008 7:36 PM Subject: RV10-List: Emailing: sb08-6-1[1] This is what I found about an hour ago.

If you look at the skin to the left of the crack, it appears to also be deformed which concurs with the failure of the bulkhead. First thought is there was substantial down pressure (compression) on the longeron and on the F1010A angle at this point. Except when rolling, would there ever be uneven force on the HS? And even then I would think the forces would be very little. Would it be possible to detect equal tensional stress on the other side? I agree with the twisted HS theory.

I believe that there is a VERY high likelihood that the root cause of the crack lies in a twisting moment induced by the asynchronous movement of the elevator trim tabs. I was the individ David refers to that flew 220RV late last year, and there was not enough up elevator trim available to take the significant back pressure off the elevator during landings. I believe this is also consistent with the trim rigging and twisting explanation. Here's an excerpt from my post following transition training. **This brings up the next point and that is elevator authority. N220RV had NO balast in the rear when we flew. We initiated our approach with 20 degrees of flaps (second detent), Turning downwind we added full flaps. With full flaps there is NOT enough trim to take the back pressure off of the stick. I found that the back pressure was much more than I found comfortable, and flew some landings with 2 hands! Makes it difficult/impossible to develop a fingertip feel on landings. The other item has been reported by several others and that is when landing it takes the full aft movement of the stick. The topic has been discussed & debated previously, but in my opinion with only 2 people and no baggage/balast there is not enough elevator. Towards the end of 8.1 hours, I was able to get some of the rust scrubbed off, got a little less shy about the rapidly approaching ground, and found a way to 'muscle' a couple of good landings. then Mike says " let me show you something, .... we took another trip around the pattern flew exactly as before only on our base leg after extending full flaps, he had me 'blip' off a degree or two of flap at a time until the back pressure I'd grown unaccustomed to holding was gone..... then flew the rest of the landing !!!!! WOW!!! what a difference !!!!! Mike why did you keep this little secret to the end??????? the plane landed almost identical to full flaps, but the 'feel' was completely different and actually a joy!!!!!** Dave Leikam wrote: > > After looking closely at the pictures, it appears that the metal is > not only cracked, but also "crinkled."
