I may also have to replace the front canopy weldment assembly. The Plexiglas has already been fiber glassed in front. Has anyone been able to remove the Plexiglas and re-install it again? A local RV builder has replaced his cracked Plexiglas by using a thin, narrow sharpened putty knife between the fiberglass fairing and the skin.

Simple physics of the gascolator may get one killed while in sustained inverted flight! Bob I agree if properly installed and the entire fuel system is purged of water prior to flight. So then what is the purpose of a gascolator? In my fuel injected system and most others that I know of, there is a very fine fuel filter prior to the high pressure boost pump, to protect the boost pump. Therefore if one had a gascolator after the fuel filter, the gascolator would not filter out any large debris. On the other hand, if one did not have a fuel filter prior to the cascolator the possible debris caught by the gascolator may then end up back in the fuel flow once gravity is reversed in reference to the gascolator (inverted flight). I assume, but may be wrong, if the gascolator did collect water while upright, then wouldn't this water then enter the fuel system while inverted? I have always thought that the force that made the gascolator work was gravity, reverse gravity and it does not work? How many pilots are able to do an engine restart while inverted? The obvious answer is to roll upright and attempt to start the engine, but trust me, when the engine quits while inverted, it gets real exciting, especially if one is foolish enough to be at a critically low altitude. In my 30 years of flying, I have only found water in the fuel once. That was after I left the RV out in the rain with the fuel caps removed from the tank (a long story). I keep looking for water in my tanks, especially since I hanger my RV with tanks 1/4 to 1/2 full. Disappointed am I, that l find no water in the tanks. I have found the entire outside of the aircraft wet from sweat/humidity on rainy days while in the hanger. I have often opined that the RV would be dryer if I parked it in the rain rather than in the hanger! But still no water in the fuel tanks! Back to the original question, if there is no water in the fuel system and the fuel filter eliminates all the fuel debris in the system, what is the purpose of the gascolator?

Subject: Re: RV-List: Plexiglass - remove and re-install - RV-9A Tip-up Joe, Look at your pictures online, Chapter 100, everything looks good, however, I don't see a photo of the tip-up. Want is the problem with the skin?

Each of the 5 or so Decathlons we ran through our aerobatic program lo those many years ago had a gascolator, and we spent a significant amount of time inverted with each student. Never once had a problem with any of them. The gascolators, that is... WRT to the pressure issue and the potential for leaks, mine is located in the left wing root and is plumbed between the selector valve and the boost pump. This makes for easy and convenient draining through a hole in the bottom of the wing gap seal / fairing. It also keeps it away from the engine compartment heat, as well as the possibility of shearing it off the bottom of the firewall in a forced / crash landing. glen matejcek aerobubba@earthlink.net ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV-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/rv-list Browse Digests http://www.matronics.com/digest/rv-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.
