I always think of these things on the weekend rather than during the week when I can just pick up the phone.... I'm finishing up the upgrades to my center spar 6W4: Do I put washers under the head and under the nut on the AN4 bolts or just under the nut? I see on the plan that just the nut. In the parts list drawing it shows both. I am tempted to go by the plan, but somebody tell me what is "best practice". What is the torque spec on these A4s? I can't find that anywhere in the docs.

Hi Steve, According to the "Bible" AC43.13, AN4 Bolts require between 50 and 70 inch-pounds with a maximum allowable torque of 100 pounds. This comes from table 7-1 in AC43.13-1B which can probably be found on the FAA web site. I don't think there is any requirement for washers in the realm of "Best practice". You need to use washers to make the bolt finished length appropriate. This means (I think) you should see something like two threads past the end of the nut when it is tightened. I prefer to put a single washer under the nut, and if two are needed one under the nut and the other under the bolt. If you need more than two washers you are probably using the wrong length bolt and should order the right length. You can get any length bolt from Aircraft Spruce, Wicks, or one of many other places. You can also get a bolt gauge for a small fee. These make it easy to tell which length bolt you have in your hand. You can tell with a ruler, but this is a bit tricky. I recommend you either get a copy of AC43.13-1B and -2A in printed form or get in the habit of looking at the online copy on the FAA web site. This document tells you everything you ever wanted to know about building and repairing aircraft. Paul Camas, WA Just finishing up the upgrade - installing finished carrythrough in fuselage.

Steve, take a look at this web page: http://www.zenithair.com/kit-data/ra/hardware.html If the answer is not there, do a little "googling"...

From: jaybannist@cs.com Steve, Best practice is to have a washer under the nut, since that is usually the one that is turned. However, if conditions require that you hold the nut a nd turn the bolt, then the washer should go under the bolt head. Another r equirement is that the bolt be such a length that the nut will not bottom o ut on the threads. Therefore, when the nut is properly torqued, there shou ld be at least two threads showing and no more than three. You can use up to three washers to help meet those conditions. The proper torque for an A 4 bolt is 50 to 70 inch pounds. The higher number should be used if it is a self-locking nut. Jay Bannister..

From: "Ron Lendon" Today, after many years of work the airplane is resting on its landing gear and the engine is mounted. I'm beginning to see the end of the build phase and looking forward to the testing/flying phase. Been thinking this is a milestone, but Anne might see it as a millstone. Either way it sure feels good... :D -------- Ron Lendon, Detroit, MI WW Corvair with Roy's Garage 5th bearing Zodiac XL, ScrapBuilder ;-) http://www.mykitlog.com/rlendon Corvair Engine Prints: http://www.zenith.aero/profile/RonLendon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=334475#334475 ________________________________ Message 6 _____________________________________ Time: 08:13:17 PM PST US From: Paul Mulwitz Subject: Re: Zenith601-List: Another Zodiac is on its gear!
