Hi all,
So there you have it. If you want to fix a bulkhead in place then there is
no reason not to do so if you wish (Europa drawings were raised to construct
it from ply and have not been withdrawn yet). It is not practical to install
it if you are Mono, due retracting gear.
The metal fire proof bulkhead (or Singleton Resin bulkhead) is intended to
be fire, fume and smoke resistant so the need for another bulkhead may just
be gilding the lily and adding weight. Your choice at the end of the day.
In 1300 hours of flying Europas without this bulkhead, both mono & Tri, I
have never experienced fumes in the cockpit with the sole exception of when
carrying out stall testing. Perhaps a good stall warning!!! I doubt the
extra bulkhead would have stopped this smell as I suspect it enters via a
different route anyway.

Folks,
A bulkhead keeps all the fumes from the engine compartment out of the
tunnel, where because of an slight lower pressure of the cabin during
flight (if you have done the air ventilation right) it will be partially
sucked into the cabin).
It takes only an hour or so to size the two 3mm plywood parts, and glass
them in (fix them with 5 minute epoxy!. The entire step took only 2
hours if I remember right. The bulkhead now serves me also beautifully
as mounting base for fuel pump and other smaller items (glider wing
spoiler mechanism bracket). It will also be protected on the engine
facing side with a stainless steel insulation blanket (Firewall 200,
Aircraft Spruce) to keep off heat and in case of fire being sucked
through (which it WILL because it follows the line of lower pressure out
under the belly) it will be stopped by this security blanket.
There is every reason for TRI to have a completely closing bulkhead.

If I read this correctly I do need need the bulkhead. Does the
stainless steel plating around the nose mount stop the air from going
down the tunnel area? I would think that the air is not stopped. I'm
wondering if there will be smells from the engine coming through the
tunnel.

Hi Phillip,
I have followed up your enquiry re the bulkhead on Tri Gear
Europas with Roger Bull at the factory. It would seem there has been a
bit of lack of joined up action.
You are quite right to notice the issue of the instruction in
the Europa Aircraft News. At the time it was issued as a structural
requirement for Tri Gears only. Subsequent analysis by Barry Mellors at
the then PFA now LAA has shown that this bulkhead is not necessary.
This is why it never appeared in the manual. Unfortunately the factory
failed to issue any notice to this effect and hence your query.
I hope this helps

This was mentioned in the Tech Talk part of 'Europa Aircraft
News' from Dec. 1999 (Issue No.24). Has still not been added to the
manual as far as I can see.
I built it in before bonding in the Cockpit Module (tricky to do
after bonding I think...), i.e. it should probably be part of Ch.17. I
first measured the actual sizes that would be needed then cut and trimed
(the ply) to fit 'exactly'.
Have attached a photo of the page (can send the original to
anyone who wants/needs it).

I have found one drawing of the front bulkhead that shows two
pieces cut to 260 x 260x3mm, but my opening is larger and I can't find
what chapter it addresses this bulkhead.
Checked by AVG.
