I had a split in a plastic fitting resulting in a large leak of smoke oil in the guts of my brand new airplane. At the time, I didnt get much satisfaction from the owner on a remedy to the plastic parts in the kit. Well, I must report that I received a call from John last week. To his credit, he offered to replace all fittings with AN fittings upgrading the kit to what I would consider aircraft grade! It took a while, but he followed up. I wouldnt feel right about not reporting this to the group I am once again a happy smoker Jeff Linebaugh jefflinebaugh@earthlink.net Original Message: Doc and all, I know some people dont care for smoke (Dennis!), but I cant live without it. I cant tell you how many times it has come in essential to either avoid other aircraft, or have someone find me to effect a rejoin. I had a great smoke system in the CJ that Val is now care takingthe best around. I just put a smoke system in my new airplane and I would not, repeat NOT, recommend it to anyone. It was a smokingairplanes.com system. It was touted as easy to install (it was) and convenient since it is a complete kit (it is.) Having said that, IMHO, I found that the system components were not aviation gradelots of cheap plastic parts. I was very reluctant to tighten down the fittings much for fear they would crackand that is exactly what they did after my first flight I had a quart of smoke oil in the belly of the new airplane due to a cracked plastic fitting. (and yes it was leak tested on the ground prior to the first flight). This system has easily cost me twice the purchase price already. When I told the owner that we were going to have to re-plumb the whole system, he apologized, and then cautioned me not to over-tighten any fitting going to the smoke pumpyou guessed it, another plastic fitting (Also, in a service bulletin, he stated that there have been two in-flight fires as a result of broken welds in the smoke injector fittings in his smoke systems. The remedy? Safety wire them to the exhaust?!) I know that there are Yak owners with his systemsI hope you have better luck than I did. Please be careful, and frequently inspect the system, fittings and smoke injectors. Given that smoke oil WILL burn, and fires are generally bad, dont go cheap on your smoke system.

There are 2 types of bicycle cable housing, use the one for brakes, not the one for derailer (or d=E9railleur.. if you believe the French...) Anyways, the bicycle BRAKE housing is Teflon lined and fits perfectly in the stock Yak / CJ adjustment ends. The combination of new cable and the Teflon lined housing makes for very nice braking. Go one step further and rebuild your Reducing valve and Differential valve. Doug Sapp has the special little seal for the inside (called a QS1 and QS2 on a Nanchang). Part is the same for Yak and Nanchang. Tj P.S.: 1) For those concerned about using bicycle parts on an airplane, see the following link: http://www.hfmgv.org/exhibits/wright/ 2) If the government of your country will not allow you to improve your airplane: Sorry. --------------------------- Thomas Johnson Airpower Insurance, LLC 36 West Ocotillo Road Phoenix, AZ 85013-1235 Toll Free: 866-475-9199 Tel: 602-628-2701 Fax: 623-321-5843 www.airpowerinsurance.com E: tomjohnson@cox.net ________________________________ Message 4 _____________________________________ Time: 12:24:58 PM PST US Subject: RE: Yak-List: filling air tanks From: "Bitterlich, Mark G CIV Det Cherry Point, MALS-14 64E" Every fill port for every type of fluid or gas that could in any way be serviced by line personnel should be labeled and clearly marked to prevent ANY type of confusion.

If someone was in the back seat, they would not have made it because of the shrapnel. Although there is no clear way to prevent someone unfamiliar with the airplane with filling the pneumatic system with O2, putting a conspicuous label at/around the external air fill port saying "compressed air only" in big, bold, letters may help at some point in time.

I am from an area where everyone who lives here is known as a "good ole boy". The color on the high pressure bottles around here are the color that happened to be in the spray gun when the guy pulled the trigger that released the mist. There is a grey and black tank that is filled with compressed air instead of nitrogen. A yellow and green that is filled with CO2. An argon tank that who knows WHAT is inside of it. So buddy.... unless you DO test it, or know for sure who filled that bottle last, you are STILL at the mercy of the folks at the FBO. mgb p.s. The local dive shop will fill any bottle with compressed air that you bring in as long as it has a valid test stamp. They could care less what color it is... after all, diving tanks come in any color that you want, starting with blue. The only people I have seen get really serious about tank color are people that work in the local hospital, but hey.. they are not good ole boys. p.p.s.

I took one of my steel (silver) dive tanks and used it for my compressed gas tank in the hanger. I took it to the dive shop to have it filled. I made the schrader valve conversion on my YAK. I bought a first stage manifold from my dive shop, high pressure hose, a 5000 psi pressure gauge, and an air fitting so I could refill my tank if it leaked down for some reason. I also bought a pony tank that fits nicely in a helmet bag with the fill hose/manifold for when I go on road trips. It guarantees me at least two attempts at a start with the amount of air in the pony tank. The pony tank is painted yellow by the way. That is the way that I know for sure what is going into my plane provided I trust my dive shop operator. Now that could be another ball of wax too I guess. We have Bubba's down here in Al too. So I feel allot more comfortable taking my own spare air on the road with me than asking a good ol' boy if they have any spare air around I can use to fill my tanks to start my plane. I sure as heck am not going to do the flammable gas test with a lighter. Now I guess one could fill a balloon or a latex glove with the gas from that questionable tank and light it off with that lighter or a flaming stick from a distance. There will be a nice bang when the balloon goes up just have to dodge the melted plastic fragments. We could also check with the local chemistry lab to see who has a mass spectrometer. They could burn the gas in a controlled combustion and analyze the gas for us. We would know for sure then what was in the tank. I believe this tread started with the question of what color is an oxygen tank. Green. Now what happens out there in Bubba town happens in Bubba town. With all the lawyers standing behind the bushes just waiting for a personal injury lawsuit if I were a FBO operator in the business of servicing aircraft on my ramp, I would think twice about being a good ol boy an just put air in what ever I could find that would hold it. Just mort one aircraft owner from filling his airplane's air tank with 02 and see how fast the $1 million liability policy will be eaten up if he even has liability coverage. So to avoid such, I carry my own air on the road. Your call after all it's your rosey pink that is risk here.
