    Yes, the Vne test is one that a lot of people are uncomfortable with - but Pete Clarke did test the aeroplane to Vne + 20 kt (at least) Miles

    Martin, I agree. And it's the reason I don't want to upgrade to 1370lbs, because the Vne test only has to be then done at 150kts. Although my particular aircraft was Permit-limited to 155kts when first built and therefore originally tested at that speed.

    Subject: Re: Tailplane torque tube bushing question
    From: "flyingphil2" <ptiller@lolacars.com>
    Hi George, I have the same problem as I am repairing a crash damaged Europa. I have tailplanes from a Classic Europa and a new XS fuselage and torque tube. To cut a long story short, the XS torque tubes and bushes are ground to a tolerance specified by a drawing whereas the Classic tubes and bushes were ground down to match each other but not necessarily to a known size. I need to do exactly what you are proposing which is to extract the old bushes and replace them with new ones that came with my XS torque tube. Neville Eyre was going to write a procedure for me a few months ago but he never got round to doing this and I never got round to chasing him up. I suggest we both contact him and ask nicely if he can write this procedure up. He tells me it is quite easy to do although will require cutting into the lower surface of the tailplanes. Regards, Phil Visit - www.EuropaOwners.org

    Subject: Re: Dive to Vne
    I suspect that those in the know would say that VNE+ dives are nothing to be worried about. After all the aircraft is supposed to be stressed to about +5g. I think that a parachute would be a sensible precaution though I dont know how easy it would be to wear one (possibly with the cushions removed). Personally I have always had a "professional" pilot accompany me when I did the annual flight test. I suspect it is the way the VNE dive is performed that is crucial. There were several instances of the wings becoming dislodged during the testing of the original Europa and no doubt due to the experience of the test pilots, no one got hurt. Perhaps someone could look into the possibility of mounting a ballistic recovery system in the passenger seat (for the duration of the flight test). If someone was able to design a universal fit for kitplanes I suspect there would be a good demand for them - subject to cost of course.

    Subject: Re: Dive to Vne
    It's presumably not vne itself which creates the main stress, but the combination of g pulled by the pilot (can be airspeed-dependent if the pilot is not super careful) and g generated by rough air (always dependent on airspeed). Can't help wondering what g loadings the crash aircraft experienced that day. Has anyone got any info on the rumour about the GPS having been interrogated during the investigation? I share the doubts expressed about the real value of repeating the vne test every year. My own Permit expires every January which means that I am typically looking for a calm day in the middle of Winter (note for US cousins - Winter in the UK usually means crappy weather, low cloud, etc) with the usual anxiety about the expiry deadline looming. Maybe some folk are tempted to do the test in rougher weather than they should. Maybe some are also tempted to do the test from a lower cloudbase than they should, leaving less height to recover and therefore the need to pull more g...? It makes you wonder.

    Greetings to all from Kenya, Here the Kenya Civil Aviation Authority do not require a dive to VNE for Certificate of Airworthiness (or Permit) renewal for any aircraft on the private register. I dont do it for my Europa, or for the Cessna 206 I fly. Not sure I'd ever want to, actually! All best Richard

I bought my Dynon for the attitude display and everything else was gravy. It wasn't until after I was flying with it I even realized that it have the AOA option. Being a builder oh and cheap too, I though $200 was a lot to pay so I looked into Dynon's and other AOA devices. Well anyway I made my own probe, cost nothing time about an hour or so and I can report it works great. Attached are a couple of pictures of the installation. The trick to ease of fabrication is that I used copper tubing, easier to solder together. The pitot tube is at a right angle to the support tube and the additional tube is angled 45 degrees down. To hold it I made a slot in the circular piece of 1/8 inch aluminum, I used my mill but it can be done with a drill and careful file work.. Mine as a snug fit to which I added epoxy. By the way don't start on how that copper is going to corrode with the aluminum I keep my plane inside and dry and I haven't seen any at other interfaces in the past year. Tim Shankland

    Vne is actually 90% of the true max rated speed Vdive. Pete Clarke actually tested Vd as required. It is simply a convention that us unwashed masses do not cross the 90% Vd line Too many flight instructors and pilot texts over simplify the structural issues If your plane is built to spec, there should be no issue in flying at Vne in calm air. Why the PFA wants you to do this annually escapes me, but it is safe. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=135046#135046

    Hi Remi My mono is far away and cannot verify how many fairings I have. I can remember four of them /wing and just one around tail wheel. That means 9 pcs. Just wonder where are two extra. Around main wheel? I have not...why? How did you install the fairing around the outrigger mechanism? I did as per instructions + soft glued it to the down surface of the wing just to keep it clean and nice. Just wonder how often I should remove it to make some service and spring check of the mechanism. I would like to hope they last forever w/o service... Paul: about tailwheel fairing; I have it and it is painted dark /black cherry (of course!). After every single take-off from any gravel strip I have to repaint it. The fairing material itself is also very brittle - so it will not last very many operations in unprepared strips. If asphalt is your runway - It is OK. I am going to stiffen it somehow structurally and also cover it by 3M damagetape to protect the painting itself. I do like how it looks.

The results are as follows: Without the speed kit, June 2006: altitude FL75, OAT 10 degrees C, that is density altitude 8500 ft, full throttle, 5000 RPM, that is approx 60 percent power, TAS 133 kts. Same day, same conditions except 4800 RPM, that is approx 55 percent power, TAS 130 kts. With the speed kit today: altitude FL75, OAT 11 degrees C, full throttle, 5000 RPM, TAS 135 kts. Same conditions except 4800 RPM, TAS 134 kts. Conclusion: the speed gain is in the 2 to 4 knots range. All flights were with full fuel, no passenger. Estimated weight: 520kg. All 11 speed kit fairings installed. True airspeed was computed using the GPS 3 segments method. Best regards Remi Guerner F-PGKL, XS S/N395 monowheel, 912S, Airmaster, 526 hours

    Subject: Re: Dive to Vne
    William and all, Vne has not directly a relation with pulling g's. You never make high speed in rough air. To catch up speed you have to dive. This doesn't mean vertical. You do it smoothly while observing your RPM and intake manifold pressure. Don't overboost your engine. The Europa is as fast as you want since the big problem was solved with the tie bar. The big problem was the displacement of the lift point forwards with higher speeds and caused the wings to tend forwards and bend the spars. When I purchased the Europa in 1999 the tie bar was standard and I was happy with this solution. During the test period a friend of mine was filming my passages over the airfield of Sedan in France. In one of the low passes I observed an IAS of 180 knots without any difference of those below Vne. My conclusion is: don't be afraid of Vne, accept it.

    John, I agree 100%. You are a glider bird, I guess. Best regards, Karel Vranken F-PKRL 93 hours. Next year with mylar tape on the ailerons and flaps. ----- Original Message ----- From: TELEDYNMCS@aol.com To: europa-list@matronics.com Sent: Tuesday, September 18, 2007 2:37 PM Subject: Europa-List: Re: Europa - Kitplanes article In a message dated 9/18/2007 2:58:13 AM Eastern Daylight Time, europa-list@matronics.com writes: There is a very good article in this months Kitplanes (page 19) in which one of the test pilots gives the Europa very high ratings in the handling category. Puts it right up there with some of the best. He also credits Ivan Shaw as being one of the top designers in experimental aviation... Hey Jeff, Yeah, I saw that, too. 'Bout time the rest of the aviation world recognized what we Europaphiles already know, huh? Every pilot I've taken for a ride in N245E has been very impressed with the handling, and equally impressed with the fuel economy and how well it slows down for landing. The handling, the Fowler type flaps and the efficient cruise were what drew me to the Europa. Mighty fine bird indeed and one that continues to impress. I don't think there's a more honest bird available in the kitplane market, at least not one I'm aware of.
