William Halford,
I can't beleve that for two weeks I missed your post! I agree with you 100%. You couldn't get me to smoke in an aircraft if you held a gun to my head! But still I have an issue with the NTSB tox. report! What's your thoughts.

AT The present time I can't say. But since I do carry TCP in a stabil bottle, I will do my own test to see how votile it is... Gary

I went back to re-read the NTSB report and the link no longer worked for me... so with that said....

I'm not certain what the NTSB was looking for when they tested for toluene, because toluene is also a major component of 100LL avgas. It's the major component that is used to bring the octane of the fuel up so that less lead may be used to obtain the LL-claim. Carrying any flammable fluid in the cockpit is a hazard....not just TCP.
Having said that, I carry my TCP in it's plastic bottle which itself is kept inside a tough, airtight cip-type plastic bag, and so that it cannot "tip" over. (Even if it did tip, it'd still not likely leak due to the bag.)
I also squeese a bit of air out of the bottle so that it's slightly collapsed before going airborne, so that there is space for expansion. The bag also is devoid of as much air as possible.
I still intend to develop a firewall-mounted storage box similar to a battery box for such items, and also oily rags and spare oil, etc. (In all my spare time I should have it ready for the next owner.) :wink:

You've got the right idea, George. Store those oily rags in a can fastened to the firewall, front side. Be sure to let me know when you get your approval from the FUZZ at the Fort Worth FSDO.

How about this George, buy the STC from Del-air that would allow you to move your battery back behind the baggage area. Than you could use the empty battery box on the firewall to store your TCP and other "Spontaneous combustion materials". :D Fringe benefit if you do an engine upgrade you will already have moved the Battery.

Hey guys, for what its worth - spontaneous combustion in oily rags only happens with organic oils like cotton seed or linseed oil, soy bean oil would probably work too. Dinosaur oil / fuel needs an ignition source.:D

You all probably knew that already. Like one of my favorite "posters" on this forum says - this info is worth what you paid for it. :P

My '53 model has it's battery on the starboard side of the firewall. I want the "box" on the oil filler side just below the votage regulator. But good thinking.

TCP

Post by N4005V »

Has anyone used the Decalin TCP additive? This is an excerpt from the aircraft spruce catalog. It claims it is for experimental use only. It is the same price, although it also claims it is not volatile and is not a hazardous chemical to ship like the Alcor product. I wonder why it would not be hazardous and the Alcor is?

Decalin Chemicals manufactures products for the experimental aircraft aviation community. Decalin Fuel Additive in a 16 ounce bottle, treats up to 320 gallons of fuel.

Decalin TCP is not approved for use in the engines of certified aircraft.
Scavenges Lead in aviation fuel after combustion to prevent lead oxide buildup on valves but still allows the lead to perform the anti-knock function prior to combustion.
It is an excellent additive for auto conversions, where it reduces buildup on oxygen sensors and plugs. If you have to use 100LL, then this stuff is for you.
Prevents valve seat erosion from valve seat micro welding. It is equivalent to TCP.
Does not contain volatile solvents so it is safe to ship and safe in the cockpit. You can carry it with you for out-of-town airports.
Easy to use graduated measuring and dispensing resevoir built into the bottle. No messy syringes!
Tested and stable down to 0 degrees F
