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there is no reason not to do so if you wish (Europa drawings were raised to construct it from ply and have not been withdrawn yet).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.

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.

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. Peter Jeffers wrote: 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 Pete Jeffers (Europa Club Inspector) ________________________________ From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com] On Behalf Of Philip Lincoln Sent: 23 June 2008 10:50 To: europa-list@matronics.com Subject: RE: Europa-List: Tri gear front bulkhead 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).

From: "rampil" Hi Mike, I have my OAT sited inside the cowl NACA vent on the lower stbd side. It seems to work well except it heats up while standing still or taxiing despite plenty of insulation on top apparently due to proximity to the radiator in my 912ULS bird. Makes my EFIS computed Density Altitude read kinda screwy while waiting in line to take off. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=189549#189549 ________________________________ Message 3 _____________________________________ Time: 02:47:07 PM PST US From: Bryan Allsop Subject: Europa-List: Strobe problem My strobe has stopped working!

Check power and ground to the unit. Ohm out from the unit to the wings. Remove unit and bench test. If a Whelen unit (especially the older ones) has set for a long while, they need to be brought up to voltage slowly. I use a 9 volt drill battery to charge it for 15-30 minutes if the plane has not been used in a long time (12 months). Some of the units had a fuse inside the unit that could be changed, but that was a long time ago. Newer units are pretty full proof. If the unit is getting power and not working, best to send it in. I have repaired one in the shop at the customer support guys suggestion, and it was a blown fuse. Unless you are familiar with the unit, do not open it up and just poke around. Whelen is great about a fast turn around on the box.

I've put mine just behind the starboard U/C legs. This gives a simple wiring run to the remote compass (just above/behind the crew's heads) and also away from exhaust or engine heat. It seems to agree consistently with ATIS-reported temps to within one degree. Willie G-BZNY - now piling up the hours again after it's little rest.
