Just make sure the flanges are 90 degree's and go with it. BTW, your moving quick.... I check you log every day.

If they are not sitting flat, go back and flute some more to get them there. Once flat they will fit correctly. Do not worry about the center of the rib. it's only purpose is to hold the flange in place. It does not have to be flat.

Cleco everything down except the last few leading edge holes to main spar. Also recommend having at least the top skin on or the bottom, just to straighten the spar out. The W919 strip is longer that what is needed. Locate the nose area on the W919, not exactly the middle. Start to work the bend into the W919. I then placed the W919 in the skin without the rib. I used several clamps to clamp the bottom side of skin and W919 making sure the left/right measurement was correct (I believe 5/8 of an inch, I check the print DWG 9 SECTION D-D and it measures 7/8 of an inch). I drilled several of the holes from spar to nose on the skin and clocoing as I went, about 2/3. I then removed to clean out the chips. Then replace on skin, cleco and clamp. Now you need a 1 1/2 inch or maybe 2 inch Dia. piece of PVC about 4 inches long. Clamp the PVC in the nose - tight. Drill the rest of the bottom holes from spar to nose. If there is no gap between the W919 and the skin with the PVC in place, then clamp the W919 to the top part of the skin from nose to spar - reverse direction. Drilling and clecoing as you go. Be sure not to over bend the W919 during the hand bending.

Mark a center line down the strip. I hope you have not dimpled the holes on the leading edge outboard skin yet. It helps to have it flat still. Bend the strip around the leading edge so that it takes the general shape of the leading edge. Make sure that the strip is long enough to reach around evenly. Mark the location of the most outboard hole of the leading edge (near the nose). Measure how far the holes are from the edge of the skin and mark another line on the strip that is the same distance from the center line you put on earlier. Drill a pilot hole in the strip where the hole mark line crosses the second line . Now cleco it into place on the inside of the LE skin. You should be able to see the second line through the holes along the edge of the skin. Drill and cleco them from the leading edge going back to the spar. You will have to trim the length so that it just touches the spar flange. there is not enough room to go between the skin and the spar flange. Now go to the other side of the wing. Push the strip until it conforms to the shape of the nose of the leading edge. Mark the length so that is close to the spar flange and cut to length. Drill and cleco the strip to the rest of the leading edge skin. Slide the tank over the strip. Secure the tank with a few screws to the spar. Drill to match Install the plate nuts and finish as normal. That is my best advice but remember that I did it almost two years ago and going off memory. Also buffing a slight taper on the edge that will go between the skin and the rib will help get it started. It will fit no matter what it appears to do.

In retrospect, it was a bitch. Like I heard somebody suggest before: if you mess with it long enough, it will fit into place. I have seen on a few builders' sites that they trimmed the strip an inch shorter that the leading edge skin on either side. So that's what I did and I'm still guessing whether that is right. The plans do not deal with this. If you are interested, I posted this on my website at: http://www.hooverandassociatesinc.com/aviation/RV-9A/wings/currently.htm Hope this helps.

(Great deal that I couldn't pass up.) If any of the rest of you have installed or are planning to install an O-290, I would love to hear from you. The engine is low time (~750 hours TT) but is in need of an overhaul. I've ordered the OH manual from Lycoming and will do the rebuild myself but what I would really like to know what others have gone through as Van's doesn't have much information about the installation of this engine. Thanks. Bill R. RV-9 SN: 90737 First Fuel Tank.

That was another item to add to my collection of dead RV-9 parts. What I did the second time around was to line up the rib with the end of the skin, drill & cleco it w/o the band strip in place. I then drew a line on both sides of the band the thickness of the tip rib webbing and measured and drilled the first hole (Aft most hole) in the band and celecoed that one and only hole to the outside of the skin w/ the rib in place. I then bent the band so it roughly conformed to the leading edge, watching the line to make sure it was "square" while I bent it. I then removed the tip rib and carefully match drilled the band to the leading edge w/o the rib in place. Once that was done it was simply a matter of deburring & dimpling them before going on to the fuel tank. As for the p-nuts, I match drilled them to the fuel tank then match drilled the p-nut rivet holes while it was still on the leading edge and the fuel tank was removed (duh!). I then dimpled the band and the p-nuts and riveted them in place with the band still clecoed in place between the rib and the skin. I hope this helps. BTW, don't worry about the fuel tanks, they aren't as bad as everyone would make you believe. Just have LOTS of gloves around and keep changing them when they get junked up. That will keep your tank, tools and you much cleaner. I'm riveting the tank ribs at a rate of one a night so I can take my time. The entire process takes about 45 minutes including prep and clean up. Good luck and keep riveting. Bill R.
