I used some extra biotherm I had left over from buying the firewall 

pass-throughs found here...



http://www.planeinnovations.com/firewallkits.html  (bottom of page)



I've been looking for a local source for the biotherm 100, but have yet 

to find it.

I prefer the high temp RTV personally. I don't like any pro seal in the engine compartment. Some people have done tests on the pro seal with high heat and it didn't react well, IIRC. I use black high-temp RTV to seal the firewall and all other things in the engine compartment.

Rick, the area in question deserves the best sealant possible.  RTV is a cheap and easy solution that does NOT meet the challenge.  I installed a product  Desoto Proseal CS-1900 which was a fiberous proseal type "fire-retandant" sealant with the manufacturers endorsement of higher temperature.  When your fire annunciator system fails.  When Your Fire Suppression system fails, your only recourse is to think of Bob Hoover and pray. Dont use RTV.  Time from point of crisis awareness to remediation is the longest period in your life. FLY the damn aircraft to a safe landing point.

  

Fly the aircraft to the accident site and insure that all POBs are safely away.  From the moment of acknowledgement of a fire  to the moment of safety, your actions speak volumes on your instruction and skill as a pilot.

  

I lost a friend leaving OSH a few years ago that failed to heed those words in his Lancair Legacy 2000. Thought he could be a HERO.

 

 "From the moment of acknowledgement to the moment of reflection on your actions , a great pilot knows the aircraft instantly belongs to the insurance company.  Your responsibility is to your passengers, your family and your brothers-in-arms who love flying after your memorial service.  "Dan Lloyd, I still miss you and pray I follow the wiser choice and don't place human life on a $ savings on RTV.". CHOOSE WISELY, FLY OFTEN, THINK ABOUT THOSE WHO WILL FOLLOW.

  

You guys slay me occasionally on the decision process you follow! DAMN I AM GETTING OLD.

Thx all, I am on my way to Aircraft Spruce this  morning to pick up a few things.  I probably will buy a tube of Biotherm  100 which is rated to 2000 degrees. I did find a write up on the Plane  Innovations web site, www.planeinnovations.com/firewallkits.html.   I will stay away from the RVT.

I fault Van's for simply calling for proseal when they clearly     should be calling for the Proseal 1900 or other suitable sealant.     While proseal may be adequate for keeping carbon monoxide from     seeping through the firewall, it gives no fire protection. Not to     mention Van's supplying aluminum heater control boxes that simply     defeat the benefits of having a firewall completely. The Plane     innovations or other stainless heater control boxes both work better     and restore the all stainless content on the firewall, and come with     a small tube of Biotherm. Also unfortunate that Van's doesn't do     much product improvement over time. Apparently afraid to admit that     something could be better than their original specifications.

you forgot to mention, that the FW is as well riveted with alu rivets to 

the structure, so that will not help either in case of a fire.

My answer to the fire problem (hope I never need it), 10# of Halon sprayed between the firewall and baffling and over the engine. From Stroud Fire Safety OKC

Werner, the fact that there are aluminum rivets crossed my mind too.  None 

the less John Cox is right, you owe it to your pasengers and yourself to 

make the firewall as good as possible.  Solid rivets are still more fire 

resistant than normal pro seal, and using the Biotherm 100 is a step in the 

right direction.



Perhaps another look at the David McNeils under cowling fire suppresion 

system is in order.

Rick

Your hosed if there is a fire! Rivets are the least of your problem, the 

issue is sealing the area around the rivets  and the areas that are most 

prone to "holding off" the fire and smoke with a heat sealant. We are 

talking buying time here, the smoke will blind and cause all sorts of 

breathing issues, hence the solid steel vents (that I know seal better than 

the Vans one) but inhaling burning proseal is not something I would want to 

add to the issue.

There are many rivets, there is a whole lot of fiberglass above the area, 

the glass will give far sooner than the rivets ever will.

A before and after photo; I teed it at the firewall, one sprayer was clamped

near the spider and the other was between the firewall and baffling. Be sure

and isolate engine vibrations from the sprayers by a rubber flex tube

between with hose clamps.

If you are worried about fire, think fire suppression. Try http://www.stroudsafety.com/FireExtinguisherSystems.html  

   

All of that fiberglass is going to burn well with a lot of noxious fumes. It's best to put it out. Fuel selector OFF, pull the pin and blow the bottle.
