I've attached an e-mail created last Dec that has 6 attachments from my personal archive of halon fire extinguisher info. The H3R website has the best info I've found on the subject, including quoting FAA stuff on halon still being OK for use in aircraft. I'm goint to have a hand held halon ext in the cockpit and a "wand" system in the engine compartment attached to a bottle in the cockpit that will go thru a secure firewall penetration to the wand system.

I've attached 3 articles saved off of www.H3R.com website (1.800.249.4289),
plus 3 e-mails with initial ideas on "how to mount".
These will be stripped off by the RV-list so sending direct to you, Glenn.
Anyone else, contact me direct & I'll fwd this e-mail to you with
attachments.
I'm planning on a Halon system in my RV-6.

Has anyone installed a fire suppression system/bottle, and if so what
brand? I searched the archives and saw some arguments pro and con, but
that was about it. A friend has a system in a Glasair and it looks like
cheap insurance to me. Thanks in advance. Glenn in Arizona -9A fuselage.

As far as
too much airflow to be effective, consider jet engines. Much more airflow than
we have and yet it works instantly, however it also releases the entire
extinguisher contents instantly.

You also have
to wonder if you're plane could get off the ground with the size canister it
would take to put out a fire like this :-)
Seriously,
the other thing I would worry about is the short term effect of the
Halon. Say you spring an oil leak, it sprays on the red hot turbo,
and catches fire. You instantly shut off the engine, fuel pumps, etc,
then fire the Halon. The Halon snuffs the fire, then dissipates
with airflow. Unfortunately, the turbo is still red hot, and still covered
with oil, so it's gonna flame right back up. For these reasons, I actually
like the dry chemical idea better.
Cheers,

never)

RE: [FlyRotary] Fire extinguishers
I've been interested in these off and on. The argument against them has always been that there's so much airflow through the cowl, that Halon might not be effective. We still have Halon in some of the MRI suites, but those systems are automated to close doors, and turn off any ventilation systems when they're activated. I know these types of systems are used in race cars, but I imagine they're usually activated after the car as come to a halt.
I'd be interested to hear some thoughts on this.
Hi Rusty;
I ran a 3/8 tube drilled with 1/8 holes every 4" which follows my fuel system. It is crimped at the end and attached to the F/W with a bulkhead fitting. On the cabin side I ran a 1/4 hose from this fitting to my fire extinguisher mount. I removed the plastic nozzle from the ext. and replaced it with a tube fitting. I leave the hose connected finger tight and ready to discharge into the engine compartment if necessary. It can be quickly removed to use in the cabin if needed. I just use a dry chem extinguisher, as Halon is illegal (and$$$$) in Canada. Will this work? I hope I never find out!
