Name: Chris, Plane: Zodiac 601UL/912 where: Thailand, Eastern Seaboard. As far as I and the Zenair man know, this is the only flying 601 in Thailand at the moment. I purchased this aircraft a few years ago, from a closed airfield where it sat for 6 years unused, and freshened it up with a new panel, cowl, and everything else to get it airworthy again, it flew on August last year, and has been performing well. It's an early Czech built 'quick build' kit I believe. (serial 7001) My question regards the fuel system, I've read all the posts I can find about this, but would like a bit of fresh advice if possible. Big centre tank (60L) with flexible hose to a centre console on-off valve, and down to the firewall mounted Zenair sump/drain, flexible hose up to a firewall mounted Facet boost pump, up to an aircraft inline fuel filter, to the mechanical pump, back to a 'T' for the carbs (Rotax 912) with another 'T' to mechanical fuel pressure gauge on the panel. All hose is 'Aeroquip' brand with fire-sleeve. When I park it on the ramp after flying, the fuel pressure gauge rises to 10psi (engine, pumps off) due to Vapour forming in the lines due to ambient heat from engine in the cowl, it slowly bleeds away after a few hours. I've never had vapour lock problems with it, but am very aware this is a dangerous scenario. I would like to reconfigure the system to alleviate this danger if possible. Open to any advice you gentlemen may have regarding this! Best regards, Chris U-Z01 PS, here's a link that features the Zodiac on a recent Search and Rescue get together in Central/North Thailand.

When I built my 701, I did not feel comfortable with the aluminum seat belt attachment that was riveted to the tunnel. In fact, somewhere 4 or 5 years ago, on this forum, I read where the bolt between the seat belt and the aluminum attachment pulled a slot through the attachment. So I made my attachment from 0.40" 4031 steel instead of 0.40" 6061 aluminum. I then used the 0.40" 6061 as a doubler on the inside of the tunnel to give more thickness to keep the rivets from pulling through. I did not ask ZAC about this, but I feel that this is a stronger anchor which actually gets pulled by both the lap and shoulder straps. Jon, you are an inspiration to all of us.

I am just finishing installing a front opening canopy on my 601HD. Ref 65 horse eng; I had a Jabiru 2200 on an Avid Aerobat and it compared favorably with a Revmaster 75 horse on my 601HD. The Revmaster direct drive had a Culver 60 X 36 wood prop and seemed a little stronger and a lot quieter. Both burned about 3 gph. Both planes had acceptable performance. I now have an 0235 Lycoming on the 601 HD. It is a very strong "0" time engine and I feel it is overkill. I really like it except for the 5 or 6 gph fuel burn. I probably would not change for the bigger engine with the experience I now have. I let the waste of the small high reving prop on a direct drive engine influence me too much. Do not let me mislead you, I think the Lycoming is the best engine for the 601, I just think the price and lack of economy is too high. In my experience I would think 65 HP would not give acceptable performance in a 601. By the way, I am probably going to build HDS wings this fall. I bet that will help the economy of my plane on trips.

I get off at 06:00 and will stop by DMAFB to hit a bucket of golf balls (practicing for a tournament in Oct), then to the airport to work on the airplane for two hours or so. Breakfast at the airport around 9 or 9:30 and then home. I have been taxing the airplane around the airport and find the ground handling very nice - although it is easy to break the tail wheel loose and make a quick circle if I attempt to turn to tight. But have learned not to do that. Starting is the biggest issue since I have to find someone *trained * and willing to assist. Hand propping is pretty easy most times. If I do not get the engine going on the first attempt, it often takes a pretty long second, third, fourth ......... attempt in the heat. I can tie the tail down by hitching to the tow-release before starting to hold the airplane. Then I add a second nylon cord (like parachute cord) to the tie-down ring in the ground and attached to the kill switch. If the airplane does move this cord will pull the kill switch out and stop the engine. The kill switch is a telephone type jack and cuts the electric current from magneto to stop the engine. Works very well. It is easy to hold the airplane after the start. Always making sure only left mag, fuel off and throttle cracked less than 1/16 th inch or so. That is after turning fuel on, letting fuel fill gasolator and enter carbs, having everything off, airplane tail tied down properly and pulling though 5 blades. Then master (kill switch) on, throttle cracked, fuel off, left mag on, recheck tie-down and pull prop. This almost always gets engine running. Walk around behind wing, reach in and turn right mag on, fuel on, check throttle at idle, move to tail and unhook cord, roll up cord on plastic handle until short enough to enter cockpit. Get in airplane, sit down with feet on brakes and carefully unclip cord from kill switch (if not careful one will pull kill switch out and engine will stop = Ha), buckle up four point harness, release tow hook and the airplane will start moving forward at an idle - but very very slow. May switch to a C85 or something with a starter next year. That would entail elongating the engine compartment because of a slightly longer engine mount. But would eliminate the hand propping - which I enjoy, but many do not. Gotta go and wash the fire trucks - Sunday chore for the crew. Do Not Archive -- Semper Fi, Steven R.

Between 1967 and 1983, military aviation was also a big part of my life. I have a Masters in Aviation Management (does not mean much) and long ago acknowledged that aviation was and is a part of my life - I would be truly sad without aviation. But, I Have Never Said or even thought that driving a car to the airport was less dangerous than flying the type GA aircraft most of us fly. It simply is not and never has been. I have always thought that pilots who thought that way were either very good at managing their risk or not very knowledgeable about a good deal of GA flying. Mr. John King, in the article you attached, said a good number of things about safety and risk management that are very true. In fact, as I start on a mentoring project for a new pilot, he will get to read John's article and then discuss it with me several times throughout his training towards a pilot certificate - no matter what level he chooses. The most important thing I can impart to him revolves around managing the risk he will take while flying. Doing so will help ensure that he and his loved ones continue to enjoy aviation throughout the remainder of his life and that his life is not cut short by an "accident". Bottom line, thanks for the article, it should be read and heeded by all of us. GA is not and never has been less dangerous than driving a car on our nations (or the world's) public streets. But it can be if we all learn to manage the risk and practice what we learned every time we fly or contemplate flying. -- Semper Fi, Steven R.

I just installed their FWF on a 601XL. The only difference (other than wing tanks versus the fuse tank) appears to be a return line in my FWF system. The return line (as suggested in the rotax information) is to alleviate vapor lock. You might want to also put another T in you main line feed with a .3mm restriction return line to the main tank. That should reduce your pressure increase and potential vapor lock George May 601XL 912s >From: "zuluonecat" >To: zenith-list@matronics.com >Subject: Zenith-List: Introduction and Fuel Systems (trying to keep it >brief!) >Date: Sun, 16 Jul 2006 07:21:50 -0700 > >--> Zenith-List message posted by: "zuluonecat" > > >Hi list, I've been quietly reading this great forum for a while now, time >for me to introduce myself!

Re: starting/groundloop- About 12 years back there was a guy at a local airport who did a credible aerobatic act in his '39 T-Craft. The compression ratio must have been down to about 2:1, because he gave the prop a half-hearted flip while walking back to the cabin and it started right up. Same guy taxiied after his routine tail up in front of the grandstand using nothing but rudder, cut the engine and dropped the tail on cue. Sounds like just the guy you need to talk to. 3.The main advantage driving has over flying is unintentional entry into IMC. You can always pull over if you can't see.

I have been drilling my Fuselage side skins. I accidentally drilled into the bend radius of the longeron splice--not the longeron itself. Because the splice sits inside the longeron the bend starts to crowd the edge distance. It's kind of a fine line. I got sloppy after a long day. I'm thinking of replacing the splice but I would have to drill new holes in the longeron-leaving the present ones open. Would this would be acceptable. Assuming I am able to follow the 3x diameter between rivet holes and still maintain edge distance. Any other ideas? I am consulting AC 43.13 for a cure.

I did a little hunting on the Internet for accident statistics. Here are the results: GA accident rate last year was 6.83 accidents per 100,000 hours. Automobile accident rate (1999) was 235 accidents per 100 million miles. Dividing that by 50 mph average (my number) you get 117 accidents per 2 million hours or 58 per million hours. This translates to 5.8 per 100,000 hours or approximately the same rate per hour as general aviation. In their piece the Kings claim GA accident rates are 7 times that of autos.

These are the GA requirements for VFR night flight aircraft. If you have registered your aircraft as GA experimental and it meets these requirements it can be flown at night regardless of your engine. It is an experimental aircraft. You may flight a GA aircraft as a light sport aircraft if it meets the requirements of a light sport aircraft and the FAA recognizes it as such. If you are a light sport pilot or flying with a private certification as a light sport pilot (non-current medical) you cannot legally fly the aircraft at night. Insurance is limited by the policy, my current policy with Falcon does not prohibit my aircraft from being flown during night VRF conditions. I have a 912ULS in my 701.

The comparison cited, while interesting, misses a fundamental difference between the word "accident" when applied to cars and light aricraft. The chances of walking away from that oft-mentioned auto accident "on the way to the airport" are presumably greater than the kind of "accident" you may have after leaving terra firma in a light airplane. While not every GA accident is fatal (thankfully), it would be more appropriate to consider the relevant statistics for "Fatalities Per 100 Million Vehicle Miles Driven." An interpolation between the rate of overall accidents (235 per 100 million miles) and that of fatal accidents in autos ( 1.44 per 100 million miles) is probably more realistic. In that light, the numbers strongly indicate -- as the Kings have said --that driving your Honda Pilot to the airport looks a whole lot safer than your activities when you become the pilot of your small plane.
