Karel,
Of course that is so true and is indeed a tip for beginners (and others)

Peter,
Clear and comprehensif. I only will ad that grass is more forgiving than
hard runways hence a tip for beginners.
Thank you,

Please be aware that the PFA have issued a safety alert grounding all
Europa's until inspected.

| Subject: | Europa safety bulletins |
To all Listers
I have just received a call from Francis Donaldson, Chief Engineer of the UK
Popular Flying Association, asking me to give maximum publicity to the
safety bulletins that have just been issued following the recent tragic loss
of Peter and William. Full details are published on the PFA web site
http://www.pfa.org.uk/fd_latest_news.asp
but I repeat here the introductory paragraph and the links to the bulletins:
This week PFA Engineering issued two mandatory safety bulletins to all
Europa owners following the fatal crash of Europa G-HOFC which appears to
have involved an in-flight break up caused by tailplane flutter. The
aircraft was an early Classic model of Europa, which had previously accrued
over 900 flying hours. PFA Engineering staff are working with the AAIB to
help them identify the cause of the flutter but in the meantime have issued
bulletins calling for mandatory inspections of the tailplanes, tailplanes
mass balances and rear wing pin attachment before next flight, with the
tailplane checks being repeated at every ten flying hours. Owners are being
sent these bulletins by post but they can also be downloaded here:
<http://www.pfa.org.uk/Engineering%20pdfs/006.pdf> Europa Flight Safety
Bulletin 006
<http://www.pfa.org.uk/Engineering%20pdfs/007.pdf> Europa Flight Safety
Bulletin 007
These bulletins are issued as Class A, and are mandatory for all the UK
Europa permit holders before next flight. However, Francis has advised me
that if anyone has difficulty in getting an inspector to the aeroplane (e.g.
they want permission for a ferry flight) he can grant temporary exemption.
Once the UK Civil Aviation Authority has issued the Mandatory Permit
Directives - probably sometime next week - then such exemption may have to
be sought from the CAA.
I understand that it may still be sometime before a formal report comes from
the UK Air Accident Investigation Board, and the investigation is still
ongoing. However, from the safety point of view PFA Engineering considered
that the sooner all Europas are checked the better.
Fly safely
Mike Gregory
Europa Club Safety Officer
PS please don't ask me for any clarification, as I have no further
information and shall be away without e-mail for the next two days.

Bruno, Thanks for the suggestion. It sounds as though it could be great fun.
We haven't yet sorted out our route, largely because we wait until the
weather situation is clear and then plan around it. If N Europe is wet then
we would go down to the south, and vice versa., I will be in touch some time
next week. Regards, David

Hi David,
I do not known your planned trip.
But when you and the group are using a trip later on over the Baltic Sea
and
when you will pass the middle western part of Germany on the 30th of June,
you could eventually drop into Oerlinghausen (EDLO, 04/22 RWY-520 m ASPH,
122,175 INFO).
There is at that time the annual summer meeting of the German amateur
builders (OUV) with a lot of different planes. Also some Europas from
Germany will
be there (I hope so) and the saturday will be the party evening.
It's a nice airfield and you can build up a tent beside your planes or use
close by accomodations.
Sunday lunchtime will be than the time for flying home.
It would be great to meet you and a lot of others there.
Have a safe and happy trip.

Sorry Chaps,
That would be UK only-based Europas are grounded
Europa owners in other countries should examine their tailplanes
as suggested for balance and then go about their business.

Ira,
With every respect intended... IMHO you should be advising all our
overseas brethren to not only check for balance but also for SLOP
BETWEEN EACH TAILPLANE (Or STABILATOR as they call them.) and ensure it
is dimensionally within permitted limits.
Regards (notwithstanding I'm not an official authority!)

Hi Bob,
Actually detection of control slop, or deadband is part of my preflight
inspection for each flight for all surfaces.
Bud Yerly and I were just reminiscing this afternoon about an XS that once
came into the shop with 1/2 inch play between stabilator sides

Hi! All (appertains to all fliers in the UK or Europe !)
Hope you don't mind my circulating this message ? Don't know what other
events it clashes with but should be a nice event..
Attached info. re. Wickenby Wings and Wheels, Friday/Saturday, 6/7th
July. Would be delighted if you could support in any way.
The club facilities have been "considerably up graded" although I
haven't personally seen them yet (been too busy "upgrading" G-PTAG!)

| Subject: | How best to taxi mono downwind with cross |
Thinking bout how to best taxi a Monowheel downwind with a cross a few
questions need answering to satisfy my curiosity:
1) If lets say we have a right quartering tailwind where the wind is
blowing reverse over wings, the plane will want to yaw right. Would full
left stick or full right stick provide the most amount of adverse yaw? In
other words would full left stick or full right stick decrease the
tendency for the plane to yaw right?
Traditional taildragger training says let wind blow stick, or left stick.
For certain it will keep more pressure down on right wing from lifting,
but I am not sure as far as adverse yaw?
2) Kinda related to #1, taxing downwind with a right quarter and wind
blowing reverse over wings, do you taxi neutral, left or right aileron?
3) Taxi downwind, right crosswind, air reverse flow over stabilator (idle)
full down stabilator or neutral?
4) Taxi downwind, no crosswind, air reverse flow over stabilator, full
down stabilator or neutral?
Thanking in advance to replies.
