    Subject: Re: An another incident for Finnish Europa around Barkaby
    I want to add my own experience to the lightning strike discussion. A few years ago while I was flying my Europa in the east of France, there were a few thunderstorms in the vicinity, the closest one was at least ten miles away, good visibility and no rain. Suddenly I saw my passenger removing his headset in a hurry and at the same time I felt electrical discharges in my left hand fingers through the foam of the stick. This lasted for a few seconds. My passenger told me he had received discharges on his ears through the headset. There were no visible lightning bolt nor audible thunder. Everything on the aircraft continued to work properly and the rest of the flight was uneventful. No damage was found on the aircraft after landing. Since that day I try to fly far away from thunderstorms. Remi Guerner F-PGKL, XS S/N395 monowheel, 912S, Airmaster, 575 hours

    Subject: stall warning problem
    From: sldpileit@aol.com
    I've got a stall warning system installed in my europa "N108EA" and I cannot get it adjusted. The darn thing is either on or off. I can't fine tune it to 5 to 7kt's above stall. This is the stall warning system sold at Europa LTD. Has anyone had any trouble with their's. I'm hoping that there is a quick fix out there. Maybe something simple that I may be missing ??????????????????????????????????????????????????????????????????????????????? Scott and Corky Dingman "N108EA"

    There is a suction and a pressure opening on the swith. Try to suck the wing opening. If the stall horn does not sound, blow on it. :-) It's a pity you started adjusting, mine was spot on out of the box. Regards, Jos Okhuijsen Visit - www.EuropaOwners.org

    Hello, Raimo and everyone, Following Raimo's report about his lightning strike, I forwarded his e-mail to Andy Draper who now works in the engineering department of the UK Light Aircraft Association (which was the PFA until 1 January 2008). Here is Andy's reply: Sent: 13 June 2008 11:00 Dear David, Thank you for bringing my attention to Raimo's report. I'm pleased to learn that he, his passenger and aircraft landed safely. We did prove that the Europa can be fully controlled with the trim at either extreme of travel and the CG at either limit so Jos's statement that the Europa would become uncontrollable in pitch is incorrect. The only other lightening strike in a Europa that I know about was to Paul McAllister in the USA. It may be out of date, but the e-mail address that I have for him is paul.mcallister@qia.net. Paul may have some useful pointers as to what he found the airframe may have suffered. I'm afriad that I have no experience in lightening strike damage. One comment that I would make is that pilot's should be aware that lighening can strike well away from the centres of CBs. The overhanging cloud should also be considered a no fly area. The other place to seek advice from would be the BGA who are bound to have experience in examining lightening damage to composite gliders. Regards Andy

    Subject: CBs & lightning
    FWIW: Many years ago, a wise old owl (now with the angels) said he had many lightning strikes while delivering heavies over the Indian and Pacific oceans, some of which caused mayhem and some of which were nominal. In EVERY case he was within 25 miles of a thunderstorm - CB . He eventually clicked and refused vehemently (Air Traffic instructions or no) to come within 25 miles (on the radar by then) - and never had another. His limit (and then mine) is 25 miles clear of a thunderstorm below freezing level and 40 miles above that because of jet wind dispersal of hail from anvil tops. I spent many an hour guessing at distances when I had airborne radar to play with since I knew one day I'd go without. We don't need to fuss too much here over in winter as CBs don't convene and FZ of 18k is mostly above our need - but summertime my minimum goes to 25 miles no matter what the challenge. JMF - just my feelings. Ferg A064

    Words change while being transferred, i have never stated "would become uncontrollable in pitch" What i told Raimo was that the force needed near one of the extremities is beyond what i can produce from a given point to a safe landing. I would appreciate the opinion of others who have run a full test program. They are all different, is it my plane only? Regards Jos Okhuijsen Visit - www.EuropaOwners.org

The positon of the stall warner hole (and thus the shape of the template for locating it) differ depending on the circumstances. I'm not sure if Classic (foam wing) and XS are different, but I think that installation at build is different from installation after wing completion. I am building a XS wing, and had ordered the stall-warner kit for incorporation before wing close. The template that came with it was marked BL52.5 and clearly wouldn't fit properly unless positioned much further inboard. It should have been BL102. Roger at the factory agreed that the wrong template was then being supplied in the XS pre-close kits and sent me the correct one. I imagine that if the hole in the LE is not correctly positioned it could make it impossible to get the sounder adjusted. If it is not close enough to the stagnation point then the pressure will not change in the expected way. Of course, I'm just theorising as I haven't yet build a fuselage to hang my wing on ... Another question that occurs is - is the stall-warner tube completely free of leaks and obstructions all the way to the sensor? Disconnect the sensor and check that you can blow through it - and that if your lovely assistant blocks the far end that you can feel the resistance to your blowing. regards Rowland -- | Wilma & Rowland Carson http://home.clara.net/rowil/ | <rowil@clara.net> ... that's Rowland with a 'w' ...

    Bob A little help and guidance in the early stages is probably going to be more useful than help retrieving a bad situation later on. When I agree to do the inspection of a project I like to do the first lay ups with the builder, it's easy to show by example, harder to explain what isn't quite perfect.
