However, the mounting bracket FL26 is bonded and bolted to the f uselage floor (Build manual 28T). Removal of the AN4-23 bolt is not possibl e owing to location of the baggage bay supporting structure. Please advise how to remove the existing actuator.

The arrival Notam has been published and EAA is selling wristbands on line. I have requested a forum for Europa enthusiasts and will post the date, time and location as soon as I receive it. We're looking forward to seeing everyone. Sorry Tim & Kingsley can't make it this year.

Shortly his speed reached or slightly surpassed 100 knots, so the exceedance was about 20 knots before he quickly stowed the flaps. After carefully examining all the flap hinge plates, the fibre-glass surrounding where they are embedded, hinges inside the fuselage and surrounding structure, flap root pins and the flap root structure generally, flap push-pull rod and lever, no evidence of damage could be found. Subsequent flight confirmed that the flaps seem to be in perfect working order. It also seems that the whole construction is commendably robust. So my questions are "How is the flap limiting speed determined by the designer and what if any factor is allowed in calculations for possible overloads?"

At the end under Europa History is stated " Don Dykins designed the Europas wing. Don, as former chief aerodynamicist at British Aerospace, had directed the development of the advanced technology wing of the Airbus." While building my Europa Classic between 1994 and 1997, I recall seeing it written somewhere that the Don Dykins wing profile became known simply as the "Europa profile" and I'll try rummaging through my large pile of Europa info to see if I can find the reference you seek. I'm fairly confident that it was never accorded a formal unique reference listing in any airfoil database.

Certainly makes me feel more confident and I have to say that I have been practicing and my landings are becoming more controlled with a very small percentage of them with a small bounce. This weekend I did a nice two hour cross country and enjoyed it greatly. Although I am sure that your landing story still applies to my airplane, am I correct in assuming you used your split gear/landing feature to land with less flaps during that extreme wind condition?

However, not very eager to mess with my instrument module now. Too lazy :) I think I am going to try just a couple of NACA on the sides. I measured where to put them to keep them out of the way. I will copy the ones in my LongEZ which work well although those are located on a place where the angle favors them greatly (compared to what it will be in the Europa) Chris Read this topic online here: http://forums.matronics.com/viewtopic.php?p=502167#502167 ________________________________ Message 13 ____________________________________ Time: 09:11:44 PM PST US From: Fred Klein Subject: Re: Europa-List: Re: Airfoil Profiles I believe that the stall warner mod has a profile of the forward most 6 of the wing profileFred > On May 31, 2021, at 2:39 PM, Area-51 wrote: > > > Read both of the Dykin writings.
