Default Firewall FIRE solutions

By now we all know what happened to eracer - we just don't know why.

In my opinion we have forgotten why the firewall is called FIREWALL.

We put holes through it, we should not, unless a bulkhead fitting is used and the firewall remains sealed. the cowling is pressurized, for cooling, and air will migrate to the cabin without proper care. This must be stopped.

Jack had a huge hole granted, 6 inches in diameter sealed with rubber grommet and aluminum firewall. Stainless Steel is good heat shield material, aluminum is a heat sink material.

I will have fire resistant bulkhead fittings where ever i puncture the firewall.

All of that will be EZ except for the heat vent, that will take some thinking

Jack's words to me were that he could not have made it another 15 seconds more in the smoke filled cabin.

Last year we lost the blond streak to fire on the ground.

Figured out the cabin heat problem - just need a 2" or so butterfly or other valve at the firewall that can block off any air in case of engine fire.

Use a metal ball valve instead of a butterfly valve. Or use a metal "guillotine" type valve.

Aluminum is a horrible firewall material, burns too easily.

Yep - some kids of metal valve to allow closing and stopping fumes from entering the cabin. Should not be too difficult to find - course i always think that.

But that is not the only hole, EVERY hole in the firewall must be treated the same with fire resistant closing or fitting.

Just treat it as the name implies

Next point is controls, eracer lost aileron control, i will replace all flight control bearings and fittings in the firewall area with SS or fire resistant material

Well, my buddy the weldor helped me with the layup yesterday and we looked at the firewall - he can make all the brackets out of SS in quick order on the sheer and brake at work, once his welding for the intake manifold is done.

not much aluminum and other materials to get rid of, but will take plenty of time - it all does!

aluminum rivets on steel tubes, wheels for the cables, etc, etc

I have to learn from others tragedies, eracer lost aileron cause we forgot what a firewall should be
