    TOP STORY
    Causes of RV accidents

    As this week's edition sadly shows, this was a tragic week for RVers. Coincidentally, a few weeks ago I saw that Ron Wanttaja was doing a presentation at his EAA chapter on the causes of accidents -- homebuilts and RVs -- and asked him to provide any data he could. He was kind enough to forward some details which make for excellent reading. (More)

    Pilot injured when plane flips on landing
    RV 3 flips at airpark in UtahAccording to a theory making the rounds at Sky Park, the plane's parking brake may have been unintentionally set. On landing, the locked-up wheels didn't spin. The plane became unstable, veered sharply and hit the dirt. That's just a rumor, though. (KSL.com)

    Fly-ins
    A great day at Tenkiller Airpark
    A few weeks ago, the folks at Barrett Precision Engines had a breakfast fly-in at their Oklahoma facility. RVator Alan Judy provided a glimpse. (Page 5 EAA 377)

    The two stages of funding your project
    In a very quiet week for RV builders this week, I decided to press ahead checking out financing for the avionics and engine. A post on the RV Builders Yahoogroup I made ended up providing some interesting information -- like you have to have flight insurance for a big loan, even if your plane isn't flying. Got more information? Feel free to post it here. (Yahoogroup)

    BUILDER QUICK Q & A & TIPS

    Removing the cowling with the leg fairings attached
    Intersection fairingsUK RV-9 builder Gary Smith recently posted on rvsqn, "I have fitted the bottom cowl to my RV9 (tail dragger) and fitted the leg fairings and it appears that the leg fairings will prevent the lower cowling dropping down and being easily removed. I can not believe people remove the spats and the leg fairings in order to get the lower cowl off so there must be a trick. Do people simply cut the front corner off of the leg fairing in line with the fire wall (seams like a large lump to cut off) and this is not a problem as its hidden under the upper leg "cuff" . Perhaps somebody could confirm what is done here.

    Pete Pengilly had the answer, "One of the best ways I have seen to get around this problem is to use springs to hold on the upper intersection fairings. So the idea would be to make the holes in the corners of the cowl large enough to make fitting & removal easy, then make the upper intersection fairing large enough to hide the holes. Glass in a couple of steel reinforcing plates into the upper fairing and attach a 3 or 4” long spring that hooks onto a point on the engine mount. A couple of pictures from Will’s aeroplane below (sorry for poor quality). To get the cowl off the top cowl is removed, the spring unhooked from the engine mount and then detached from the fairing. Fairing is slid down the gear leg and bottom cowl removed."

    A tight plexi fit for Duckworth lights
    A tight fitThe method of attaching the plexi in the lights to the hole you cut out of the wing leading edge is problematic. Phillip Kaye has been working on it this week. "The old fit was done using just the tape handle to pull up on the lense. For the new fit I reached in from behind and applied significant pressure while my wife used a marker to mark the plexi by putting a dot through the existing holes in the skin. Then I took the plexi out, drilled it and replaced the metal backing platenut strip. I think that one spot with the gap is due to a deformation of the skin (perhaps resulting from cutting and smoothing the cut-out," he says. (Google group)
