Matt, My rule is to carefully inspect each line, pulling back each b nut to inspect the flares. If you use a good 10x magnifying glass, inspect it that way. But you can can use lines again without reflaring! If find a crack discard, make a new line..

Matt: Just check for cracks and any debris. You can re use these with no problem at all. FYI=2C you really DON'T want to use fuel lube on these AN fittings. That stuff is mainly used on Pipe thread fittings where the fluid will lea k through the threads. On an AN fitting=2C the flare fitting takes care of that.

The unit worked perfectly. It was easy to set the desired Oxy flow. I've been in the USAF altitude chamber a number of times and I know my hypoxia symptoms perfectly and I had no indication of hypoxia. I test flew the bottle to 17.5k feet before going higher so as to make sure I knew how to use it and insure proper operation. I can't recall the brand name offhand, but I will find out which one it was and give you a pirep on it. Should I buy one, it is the one I will buy. Personally, I would not install a permanent O2 system in a RV. That would mean carrying around the weight for the life of the airplane. RVs tend to get overweight anyway, so flying around with something that might me used a time or two per year is, for me, not worthwhile. The issue with a portable bottle is finding a place to store and secure it for the flight. If you're solo, then the solution is relatively simple. I put it alongside my seat with a SS hose clamp to hold it to the sidewall. A better means of attachment could easily be installed with several hose clamps attached to nutplates on the sidewall. With a passenger, the problem is more complicated. You need access to the top of the bottle to adjust the O2 flow, so storing it away in a baggage compartment is not feasible. I've seen some "backpack" type harnesses the hand on the back of the front seat, but there are issues with that also - you have to depend of the passenger to adjust the O2 and the rear stick would have to be removed to avoid any possibility of jamming against the bottle. Of course the 6, 7, and 9 can put it behind the seat and reach over for adjustments. Stan Sutterfield In a message dated 7/10/2011 3:11:00 A.M.

I have an integrate d system in my -10 which was the right call for that plane but I don=92t see the need for a permanently fixed bottle on the 8A for my mission. I can see a removable bottle or even just a bottle & padded pouch to place in the cockpit for occasional X-Country use and no hard mounting of O2 pick up locations. Does anyone have a suggestions / photos of the systems they use? I am looking for practical solutions, not full blown O2 system in the forward baggage & routed hard lines.

I misread your comment. I'd like to think that each pilot does think about his experience level and flying time in order to create his own self imposed limits. I believe that an even more important consideration is how much exposure the pilot has experienced with unusual or demanding situations. I've found that I rarely fully consider all the possible outcomes and consequences of a given situation. If I survive the situation without damaging anything, then I do my own NTSB to analyze what else I should have considered and how I can make a better decision the next time (note that the next decision could be the same as the first one - except that additional knowledge makes it a more learned decision). I'd like to remark about your statement "The FAA is already pricing flying out of most folks reach..." I do agree with you that flying has become terribly expensive and out of reach of most Americans. The FAA has contributed heavily to the problem without commensurate benefits. However, I've owned ten single engine aircraft over the years. I remember selling my 1962 C-172 in 1976 because the cost of flying was "out of control." The cost of Av gas had reached 76 cents per gallon and people could not afford such prices!!! And woe was us because the government was going to force us to all use LL fuel and all of our engines were going to die and cost us millions. Now we are facing the end of LL fuel and many journalists are crying gloom and doom again. It seems to me that people who love flying airplanes will find a way - I know I will. One disturbing trend though, is that of airspace restricted from GA operations. The massive use of TFRs is out of control and AOPA seems to welcome the trend - instead of fighting as they should. Have you tried to navigate to DCA lately? You, as an American citizen, cannot use DCA as a navigation point. And it is restricted only for the convenience of the TSA. There is even a TFR over Disney World!! That is simply political cronyism. Pilots should NOT have to worry about an interception or a violation for flying over Disney World at 1500' AGL. Okay - this rant is over, too. I get fired up too easily, I guess. Regards, Stan Sutterfield PS - I've dropped my AOPA membership because they no longer stand for what is right. There - that should get some rounds coming my way. : ) In a message dated 7/11/2011 3:03:32 A.M.

The last thing I would want on earth is another government involvement in anything. The FAA is already pricing flying out of most folks reach, with a LOT less benefit created than their astronomical, bureaucratic cost. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv8-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV8-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rv8-list Browse Digests http://www.matronics.com/digest/rv8-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
