(H.Ivan Haecker) ________________________________ Message 1 _____________________________________ Time: 05:07:55 AM PST US From: "RV Builder (Michael Sausen)" Subject: RV-List: OT: Interesting Airventure story I saw an interesting story this morning on the local news. Apparently EAA is planning a 10 year project to expand the Airventure grounds and build 2 new exhibit buildings. The current plan looks to link the existing 4 buildings into two pairs buy building a new two story building between them and updating the existing buildings with the usual convention center amenities like bathrooms. The city of OSH is talking about abandoning their existing convention center downtown and teaming up with EAA to turn Airventure grounds into a new OSH convention center. I bring this up because a lot of people feel that EAA has become too commercial and has forgotten their constituency. I know this is the first I have heard of this and a quick search on Google turns up nothing except a couple of the local news stories. I would think that EAA would want to share such large initiatives with the members before going full speed ahead. I don't think this is necessarily a bad idea, and OSH could certainly use the additional resources year around, but I would like to know exactly how EAA feels this will help experimental aviation advocacy and how they feel this will help the organization. This isn't a cheap endeavor at 20 million and it's a lot of our EAA dues going into it. My point to this is, if you are a member, let EAA know how you feel about this being done whether it's good or bad. http://www.myfoxnewisconsin.com/myfox/pages/News/Detail?contentId=6636115&version=1&locale=EN-US&layoutCode=VSTY&pageId=3.2.1 do not archive ________________________________ Message 2 _____________________________________ Time: 09:30:12 AM PST US From: Matt Dralle Subject: RV-List: Aero-net Reuse...

From: "John Cox" Doing it and making it right are two entirely different questions. Paragraph 7-64 f. addresses nylon nuts. Aviation safety can be expensive. They progressively wear and fail to provide the purpose of a nut, which is retention. I see it all the time. They most often do not pass inspection criteria. Common opinion is what Matt asked for so I will say many things in Experimental are "penny wise and pound foolish". It is amazing the risk one will take to save a few pennies. From a Quality Control perspective it is "Use a new one every time" or check the torque...that is the trouble. When penny pinching, they will often hold torque 1-3 times then are trash. I often find nuts being used on experimentals that are shot and reused by operators that don't have the baseline knowledge found in the AC43.13.

I expect that the revenue from renting the spaces would ultimately cover the costs. At least it appears that's the plan. ________________________________ Message 12 ____________________________________ Time: 07:15:30 PM PST US From: "Emrath" Subject: RV-List: Fab Bypass Filter Starting around late 2003, or so I think, Van's put out a modification for bypassing the filter in the FAB should the filter get clogged. This is for the vertical induction carb or FI-servo installations. The original method utilized a magnet and then a revised version utilized a cable operated by the pilot. At the time, when I first fabricated the FAB, I modified it according to the original method using the magnet. Today, as I finish up my panel and get prepared to put the forward top skin on, I began thinking about this once more. So, I'm wondering if anyone still has the magnet version of this modification on their ship and can tell me if the bypass magnet releases and lets air bypass the filter under NORMAL operating conditions or not. I'm driving myself crazy trying to determine what the NORMAL psi differential might be on this door to compare the calculated force needed to open the door and the amount the door will see during NORMAL operations. Anyone/everyone have some thoughts on this?

I was told that the reason they changed from the magnet was because it was opening during normal operations. After giving it some thought I decided that I would put one in at all. I am not going to be flying in conditions that will cause the filter to ice over. ---- Surfing the web from Hopkinsville, KY Visit my flying RV7A web page: http://home.newwavecomm.net/bobbyhester/MyFlyingRV7A.htm Emrath wrote: > > Starting around late 2003, or so I think, Van's put out a modification for > bypassing the filter in the FAB should the filter get clogged.
