Hi Craig,
It is a must in Germany and other countries to do a positive static
g-load
test. You have to support the fuselage very strong and rigid with the
bottom
upwards.
You install the wings level and measure the distance of the wing tips to
the
floor (using a mixing stick, taped on the wing tip.)
Then you have to put weight on (sand sacks or cement sacks with 25 kg
each)
in an exactly definite position and in three steps, so at the end you
will
get the full load as required and in the correct position on the wings.
After each (loading) step you have to measure the distance from the
wingtip
end to the floor.
After these three steps you remove the load and measure again to get the
setting difference of the whole plain before and after the loading
procedure.
With this test we demonstrate the maximum wing load. We do not do flying
load tests as the results can get worse (accident Miles/Sweeting). We
have
got also wing load tests which failed do to not proper made fuselage.
Believe me, when you do this test in the very late phase and you can
hear
the noise and cracking sound of the fuselage setting and the fuselage is
still ok after this, the next some pints of bitter are tasting terrific
good. Attached are some info about the set up and procedure of the wing
load and tailwing load test.
If you need more info, please let me know.
Safe and happy flying,
Bruno

Betreff: Europa-List: G Load testing
I have seen a few photos on the group over the years with
a/c inverted and bags of sand, concrete, gold coins etc stacked
evenly on the wings to simulate the G loading, question is how are
people supporting the weight for this test through the fuselage itself
obviously the top of the cockpit would be insufficient to take such a
load
of what 8000+ pounds, assuming 6g x 1370lb, or do I have the math wrong
on
this
my thoughts were it may be easier to keep the A/C upright and load the
weight
into the cockpit with the whole lot supported by cradle and a few extra
supports under each wing

Yes but doesn't there have to be a 50% safety margin on g load
After all you could pull nearly 6 g in a turn (80 degrees bank) taking
Evasive action for example.
But back to the original question how does one support the a/c adequately
for the testing in the inverted
position

Graig and all,
The 50 % margin is for calculation only, especially in a homebuilt.
Contrary to popular belief, the 4.5 g load for instance, is a
once-in-a-lifetime limit not to be inflicted on the airframe repeatedly.
Safe load is considered to be approximately 80% of certified load.

Any airplane can break in flight if mishandled.
It would take a really ham fisted pilot to reach as high as 6g.
Additionally in peacetime I would advise to only perform avoiding
actions ;-)

She Fly's !!!
On the 24th July 2013 at 16:17 Local Time G-IRPW finally lifted her
wheels from the surface of Wombleton Air Field in Yorkshire, UK. First
flight was carried out by Very professional Pilot Ivan Shaw. Ivan's
first report on landing is,
"She fly's beautifully with no problems, balanced well and
flight straight and level"
There are a few miner tweets required but nothing major required.
The Build was started on 20th December 2005. Total build time 7 years
7 Months 4 days and counting. Total hours 1800 Approx.
I would like to to take this opportunity to say thank you to all
who have given their support over the years.

Clive,
We made a strong steel support for the wings to avoid any damage to the
fuselage. I published a short report about our load test with some pictures
in the Europa Flyer #30, that you can find on the Europa Club website.
The load test is worth wile, but it is thrilling! Good luck

Hi All,
Not the best week for me as I am scheduled to work, but may be able to get off.
Probably chilly then too but I'll take what I can get. Haven't got to fly much
this year due to rain every day or a wet field when it's not or work. Hopefully
things will get better soon. Hope to see you all there and have a beautiful
weekend. Pencil me in. I'll call and get reserved. Thanks.
Troy and Donna

| Subject: | Replacement tailwheel |
Hi All,
I still have my original 10 y/o tailwheel on my Europa. Its starting to
get a bit worn and hard after 1100 hours so I thought it was getting time
to replace it.
I ordered a tailwheel for an RV from AC Spruce but when it arrived I
discovered that the tread width is 1.5" and the one on my airplane is 2".
I have been searching around for something that is 6 x 2 " and I found that
Colson casters make one. It is a 400 lb rating and roller bearings. I am
using 4" Colson casters for my out riggers and they seem to hold up to the
landing speeds.
I was wondering what others have dome for replacement tail wheels, and has
anyone tried Colson as a tail wheel.
BTW, the AC Spruce wheel cost $125, the Colson wheel cost $11.50 !
Thanks- Paul
