I never see the 106's drop below 3 psi. One more point of interest regarding pumps and plumbing... I had the more powerful 45gph Facet on my firewall to play the role of 'engine pump' (i.e. no mechanical pump on my engine). I have a Facet 105/6? at each fuel tank for positive pressure/balancing. I discovered that with both the wing pumps AND the firewall pump on, my fuel line pressure was adding up to more than the carburettor limit of 5 psi. I've replaced the 45gph Facet on the firewall with a third 105/6 Facet and now the system operates as originally intended - i.e. all pumps on full time except for balancing (if required). Moral of the story: take into account the adding of pressures for pumps mounted in series. -- Grant Corriveau C-GHTF / HDS / CAM100 ________________________________ Message 3 _____________________________________ Time: 06:24:29 AM PST US Subject: Re: Zenith-List: Extinguisher From: Grant Corriveau --> Zenith-List message posted by: Grant Corriveau > From: Michel Therrien ... > I was told that the problem with a Halon extinguisher > in a CH601 is that there is too much ventilation in > this aircraft.

No, it doesn't match my experience with Halon Extinguishers. Airliners in Canada (and the world?) are still equipped with Halon 1211. I have conducted training courses putting out actual fires (much larger than anything I ever expect to see (and survive!) inside a Zodiac. The Halon knocked the fire down almost immediately. It doesn't have to KEEP oxygen away from the fire for a long time to BREAK the chain reaction. We were doing this training outside with the fire set inside a typical airline galley unit with the door removed - i.e. highly ventilated. The fire was lit (by a professional fireman btw!) and given a few seconds to grow. Then the trainee would move in and attack the base of the flame with a sweeping motion. One or two sweeps (i.e. a couple of seconds) and the fire was out. Yes, Halon produces toxic fumes so it is important to ensure ADEQUATE VENTILATION ASAP after discharge. Given the ventilation characteristics of the Zodiac (mine at least ;-), I think Halon would work very well and with a vent or two open immediately after use, should not provide any worse 'side effects' than THE FIRE itself!! ;-) My opinion only fwiw. BTW Michel - where did you purchase your Halon extinguisher? In Montreal? I need one.

So, anyways during the landing rollout the nosegear was damaged by the guard-rail along the center of the drag strip and the nose came down, and there was some smoke from below the cockpit floor etc... After the pax were evacuated, the pilots dishcharged their own extinguishers into this area, and several others that were handed to them by the Drag Racers.... several different types. The pilots were obviously determined that after surviving this harrowing experience they weren't going to sit around and watch their aircraft burn up! The investigation afterwards revealed that there really wasn't a fire, and the different chemical reactions from the various extinguishers caused more damage to the electrical components than the actual nose gear collapse... oh well! Bettter safe than sorry! ;-) fwiw -- Grant Corriveau C-GHTF / HDS / CAM100 ________________________________ Message 5 _____________________________________ Time: 06:38:26 AM PST US Subject: Re: Zenith-List: Extinguisher From: Grant Corriveau --> Zenith-List message posted by: Grant Corriveau > From: Michel Therrien ... > (to > have a fire, three things are needed, oxygen, a > combustible and heat). Some extinguishers work by 'smothering' the fire (i.e. dry chemical powder); some work by reducing the components below their 'flash point' temperature (i.e. water), and others work by instantaneously reacting with the heat to produce a chemical reaction that momentarily absorbs the oxygen and breaks the chain reaction (i.e Halon). Or so I've been taught... fwiw -- Grant Corriveau C-GHTF / HDS / CAM100 ________________________________ Message 6 _____________________________________ Time: 06:43:49 AM PST US From: "Al Young" Subject: Re: Zenith-List: ZAC newsletter - cool stuff! --> Zenith-List message posted by: "Al Young" Ray- Was at Mexico, MO yesterday.

If you have an oxygen system built in, Halon away. If you do not, you run a significant risk of hypoxia and losing consciousness. The idea with halon is to displace oxygen element from the fire triangle. The problem is that you displace oxygen from the lungs as well. If you are talented enough to hold your breath long enough for the fire to go out, you will still have to vventilateshortly thereafter and run the risk of a rre flashwith little or no agent available for suppression. IMHO - There are non corrosive dry chemical fire extinguishers out there - but if there were not, I would much rather replace my entire electrical system due to corrosion than lose consciousness in flight.

Ten years ago I started taking coumadin after a double bypass and installation of a plastic aortic valve. Nine years ago I passed my flight=20physical and have every year since. So, it can be done. However, it is an expensive process and requires a flight surgeon who specializes in difficult Special Issances as well as a Cardiologist who is familiar with FAA medical requirements. A special trip to OKC to meet with the Special Issuance people also can be very helpful. As they told me after doing it the hard way "Why didn't you=20call us at first, remember we're here to help you". My plan, should I lose my medical, is to build HD wings for our 601 HDS and fly on my driver's license. Good Luck on whatever course you choose.

Good post. Actual experience is always welcome and often more useful than theory. I did not purchase the extinguisher yet... I went to Safety First and they don't sell Halon anymore. They sell a replacement that contains FE-36. To get the same capability as a 1lb Halon extinguisher, you need to buy a 2.5lbs FE-36 unit, however. I'm going to Osh and I hope to find one there.

Is useless to handle the stinguisher like a mosquito spray (all over the place), I know it gets very hot, but get as close as possible to reach that base of the flame, if is not possible, then is a job for the professional firemen, get as far as you can, you will not be able to control it... I important to reach all the base, any fire left will get it back to maximum fire is seconds.

I have it print and give a copy to the new pilots on the club every time we practice deadstick landings: We go about 1,000 ft over the strip and over the mark, then cut the engine and land, the winner is the one that touches firm (no bounce) and gets closer to the line, first place (3 axis) in this event (last May) was a Kitfox 6 912S, that floats like a glider, Alberto Barba is a great pilot. Trikes are always first place over all. The last place has to perform at least 3 spot landings in a row (with engine working) to be able to fly in our strip. This last event the looser was a pilot with a QuckSilver GT 500 912 80HP. Is mandatory at least 2 times a year to be able to fly in our club, there is one about every 4 months, it includes theory and one practice landing with the instructor (if the plane is two seater).

I would be more worried about the corrosion in my lungs or trying to see thru a cloud of chemical dust. The FAA and NFPA recommend halon, preferably 1301 as it produces fewer toxic by-products, for small aircraft. The amount needed to extinguish a cockpit fire is not sufficient to render one unconscious, vs. CO2 for example (according to everything I have read). Because Halon is similar to freon it will not be available soon, so if that is your choice you should be buying it soon. Here is another link specifically dealing with small aircraft firefighting.

I am at the point of installing the rear fuselage HT Frames on my 801...Specifically, the forward HT frame, with a level laid acrossed the top of top, left and right longerons I can get them level. When I lay another level vertically against the outside skin I am unable to get the top and bottom longerons level because the HT frame is too snug and won't allow the top longeron to be moved inward to be over the top on the bottom longeron and thus level in that plane. Have others had this problem? If so, what was the resolution? Thanx in advance for any help... -Scott Also, if the other 801 builder using a mazda rotary is out there, please contact me as I cannot for the life of me figure out how to get the engine to work, that is without going plugs-up, using a 200mm thrust line.... ________________________________ Message 18 ____________________________________ Time: 07:11:33 PM PST US From: Michel Therrien Subject: Re: Zenith-List: Halon --> Zenith-List message posted by: Michel Therrien Very good article... thanks! do not archive --- caspainhower@aep.com wrote: > http://www.h3r.com/products/cockpit_fe.htm ===== ---------------------------- Michel Therrien CH601-HD, C-GZGQ http://mthobby.pcperfect.com/ch601 http://www.zenithair.com/bldrlist/profiles/mthobby http://pages.infinit.net/mthobby __________________________________ http://sitebuilder.yahoo.com ________________________________ Message 19 ____________________________________ Time: 07:26:21 PM PST US From: Hal Rozema Subject: Re: Zenith-List: Extinguisher --> Zenith-List message posted by: Hal Rozema ACSpruce has them Michel Therrien wrote: > --> Zenith-List message posted by: Michel Therrien > > Thanks a lot!
