Mike

Your timely warning reminds me of a similar but different problem found on my 912ULS at last permit renewal. One of the coolant pipes was found to be burnt by an exhaust downpipe. The damage was confined to the heat shielding which had burnt right through and was about to burn through the rubber hose. Basically, the hose routing was too close to the downpipe - a previous owner had wrapped it up with heat shielding to compensate. An extra reason why this was alarming was that a 912-engined DynAir Banbi in the same hanger had recently suffered a complete loss of coolant through an identical problem (the owner lived to tell the tale but had his wallet lightened by an expensive engine rebuild). I believe Mike Gregory has some gory photos of the damage.



Happy flying

 For all Europa owners with Rotax 914.

  

 Just preparing to incorporate Mod 72 and took the opportunity to have a good look around.  I found one of the oil pipes badly charred by No1 cylinder exhaust pipe.  The pipe concerned is the one that connects the oil cooler to the oil pump.  Fortunately, when I installed the pipe I fitted some heat shielding from 'Demon Tweaks' - the heat shield was burned through and the pipe was just starting to be affected.

  

 On initial installation the pipe did not touch the exhaust, so the bend must have eased during  use.

  

 Looking at the installation, it seems that a slightly shorter pipe after the bend where it connects to the oil pump should solve the problem.

  

 Hopefully, this is a one off and my aircraft is the only one affected.

  

 But I thought all you chaps might like to know.  It is worth a quick look - a burst oil pipe in this position could be very dangerous.

  

 Kind regards,

This is one of the ‘gory photos’ Willie referred to, taken of the hose damage on an MCR-01 Banbi fitted with a 912.

So... Has anyone got a satisfactory solution to this  design disaster??

Use silicone Hose instead of rubber  with suitable heat reflecting sleeve like   http://www.agriemach.com/product_info.php?cPath=0_7&products_id=393  

And using slightly longer pieces of hose you can route them further away from the heat source,  

But Regular check of hose condition is recommended,

Hi,

  

 If you  take a look at http://europa363.versadev.com/ under  January 2004 you can see  a few pictures of what I did.  I re routed  one of the oil hoses to run on the port side of the motor, across the back of  the engine mount and up into the oil container.  I used Teflon braided  Aeroquip 666 hose.

  

 So far  this has held up fine for 600 hours.

Routing hoses is an art more than an science.

But achieving a satisfactory result is not so difficult with a little care.

Not to mention the bubble-wrap and masking tape  "insulation", nylon tie, other cable conflicts and gobs of red insulating  tape (also heat stressed and burnt at the edges).

  

 The "cowboy" standard of  construction obviously leaves a lot to be desired; but maybe it was  "....... all the Inspector's fault....." (if there was one)!

Paul,

  

 I just tried to access your website but can't  get to it. I hope you are not shutting it down for good. It is a great resource  for other builders like me.

  

 Actually I was looking for the information on how  much Redux you have used for closing one wing. I am finally getting there after  concentrating more on the fuselage before. (I built out of sequence.) I  have about a 1/2 can of the yellow paste left. Originally I thought to  substitute with the stuff from Aeropoxy but after the recent postings I do not  want to mess with the wine skin anymore. I suspect a lot of flexing and  sheering forces on the wings.

  

 Regards

Michael,

  

 The  server fro my WEB site resides in Australia.  I'll check with the guys on  Monday if its still not up.  As far as your question goes I'd have to troll  through my hard copy but I seem to recall about 1/4 of a tin per wing,maybe a  little more. 

  

 One  trap I found was that the flox dries out the mix when you let it stand, so don't  get too carried away with how much flox you add.  I applied mine with an  empty calking compound tube & gun which was 10 times easier than hand  spreading the stuff.

  

 I  don't want to lead you astray but I would have no problem in using post dated  stuff because the two compounds are chemically inert until mixed, I invite you  to do you own research on this.

Michael,

 I used about a third of a tin per wing. Both wings  done out of 1 tin, with a significant amount left over (1/4 to 1/3 tin  left).
