Netters, To answer the question on my collapsed news gear. It was a standard Diehl metal nose gear that was sold for the VW powered standard KR. It really survived the first hard hit but the second hit was much harder. It bent just below the upper socket that it fits into., Also it bent back about half way down the gear leg. We slid down the runway on the lower bend and almost ware through it. The nose wheel turned 180 degrees after we went off the pavement and into the dirt. It sheared off the nose gear stops that were to keep it from going to far around. There isn't any damage to the tire, wheel, the aluminum casting or the fire wall. I'm impressed with how strong the wooden KR fuselage is! The Diehl gear comes with a socket fitting that bolts to the firewall and also to the lower motor mount. It doesn't show any damage. The only damage to the (home made) motor mount is from the acid that ran out of the battery vent tube. and messed up my paint job job on the motor mount. The vertical tail was snapped off. I have removed the elevator and carved out the two spars. I have enough foam to make the new vertical and rudder. After I get my Spruce order I will get on it. David Goodman's E-mail with the pictures of my KR gives you a good look ot the bent nose gear.

Where did it fail? Whose nose gear was it? Diehl? He has two, a standard and a Corvair version (don't know the difference). Do any recommendations come out of this incident regarding the mounting of the nose gear? Jim Morehead was the builder of this plane, so he final authority on the nose gear. It appeared to me to be a standard (VW) Diehl system. As far as where it folded, you can take a look at link http://sites.google.com/a/wildblue.net/goodmans/Home/2010-kr2-mishap. There is a good photo from the side of just the nose gear located there. We hit extremely hard on the nose on the first bounce. I could not tell you how hard the second hit was compared to the first, as my eyes were completely uncaged for about one second after the first impact. What I can tell you is the gear did not shatter until after the second impact nose-first of the plane onto the runway. I know this because though my eyes were uncaged I could still see the prop shatter on the second hit. That the landing gear withstood the first impact is a testimony to the Diehl gear's solid design. Having nose-planted my own plane three years ago on a Corvair-weight gear (which bent, but did not fail) and last year taking that same strut off-roading at 35 KTS off a runway in California the Diehl gear is superb. In both my excursions outside the norm I took the strut to a muffler shop and had it bent back out ~15 degrees or so... good as new. A safety plug (again) for those new to the plane. My own first bent strut came from an inadvertent takeoff during high speed taxi. I pushed the nose over (1/16 to 1/4 inch stick forward) and came crashing down on the nose. The second came on a landing in very rough weather and one of my brake pistons failed. Not able to stop, I bled as much speed off as I could before the end of the runway. Nothing I could do about it, but the strut held again, though I dug a good sized furrow with the nose tire in the soft dirt. Sorry for the long answer. If you need more data, let me know and I can e-mail you privately.
