Hi Bruno,
there is even more to think:
When green on, you know the bolts are in AND whole system is
operational.
If green (should be red then!) off means bolts are in, how can you be
pretty sure system is ok? If you loose your microswitch or led or fuse
your greens are off and you think bolts are in but maybe they are not.
Cannot be sure!
***
I give you an example:
We have a personal well water in our home. Sometimes in the spring time
the water level goes too low and there is a risk we run out of water.
That is really awful.
That is why I built a warning system like this:
1) We see two blue high bright leds in the house when we have water more
than enough.
2) We see only one blue led when there is still water but not so much
= we have to save it, no jacuzzi any more!
3) We see no leds at all when we have less than 500 litres water which
is a critical amount for us.
So, no led means save water OR system is somehow broken. Problems
anyway.
System cannot jam (there are electrodes in the well) =93 blue led
meas surely we have weter =93 they cannot light if the electrodes
are not in water.
***
Same w Europa=C2=B4s doors and gears and similar =93 better to
have indication when all is ok.
If you really wanna play w gizmos put greens when bolts are closed,
orange when open and reds + bell when open AND airborne or gear
retracted (if you have!). That what I did...fool proof.
Cheers, Raimo

Hi Raimo,
In fact, my first idea was to use the green LEDs as you suggest. LEDs on
= doors closed. But than I thought, better no lights on when system is
ok. But you are right; green lights will give you a safer feeling. In my
opinion, as the rear door bolts are critical, switches on the rear bolts
should be do it.
I have seen your pippins to secure the handles. I will do the same for
the passenger side.
Have a nice and safe flight time too.
All the best,
Bruno

Hi Bruno,
I elected to make a system which have two serial connected micro
switches per door. When they are BOTH IN I have a green led. When I have
two green leds I am pretty sure my doors are firmly closed.
Otherwice, they are open OR system is somehow broken. Two Greens = The
System is operational = The Doors are closed.
Maybe you would like to have red lights (when doors are open) instead of
greens or change MS=C2=B4s to be NO (normally open [when doors are
open]) as I have them.
I promise what more you see green lights when flying that happier you
will be (there are possibilities to have masses of green)! ;)
***
Notice also my extra safety: there is also a pip-pin to prevent an
unwanted inflight door opening.
Just my =C2=BD penny or how those englismen that says so gently and good
luck for you!
Raimo

Hi Roland,
I would leave the door inside its door frame and would wait for warmer
days; maybe it will set by itself after a while.
The best protection for this is to built in an advice. I will install in
springtime two micro switches mounted on an aluminium plate together
with a common carriage bolt (Schlo=C3=9Fschraube).
Please see attached pictures (just made for you). You have to make one
mirror inverted (spiegelverkehrt). The switch-bolt arrangement weights
35 gramm each.
In my panel I have fitted two small green LED lights and the micro
switches are openers. When the door is correctly closed, the LED will go
out.
Best Regards,
Bruno

Betreff: Europa-List: Deformation of canopy
Hi all,
yesterday something embarrassing (and dangerous) happened to me. After
departure (already in 5000 ft) I noticed that the door on the
copilot-side was not locked on the rear side (I almost hear you saying:
"that cannot happen when you worked through the checklist prior take
off"). You are so right!
After the first shock (suddenly the appropriate passage of the POH came
crystal clear in my mind: "when the door springs open it will most
likely depart the aircraft") I asked my Co to pull the handle in front
and I did the same on the rear.
I was so lucky to land with my Europa as a whole!! When leaving the
aircraft my Co noticed a resistance when opening the door. It turned
out, that the frame on the top of the door seemed to be deformed in a
way that the gap between door and frame/roof became too small causing
this resistance approximately when half open (then the door frame
contacts the roof frame) . When complete open or closed everything seems
normal. The hinges and screws where it's mounted are apparently
undamaged.
Does anyone have a suggestion how to bring the door into a perfect fit
again?
Thanks for your input!
Regards
Roland
