All aircraft in Alaska have to be able to land on water don't they? >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> ----- Original Message ----- From: Ken Montoure - GCI To All Pietenpol Affectionados: Hooraa, Hooraa today was the BEST!

    Subject: Parts List - Aircraft Spruce & Specialty
    And now for the impossible question... Background: I am building an Aircamper in the Alaskan Bush to be known as the Bethel Belle. This means that getting everything up here the least expensive way (i.e.: barge vs. air) is the first priority. Specifically that means virtually "everything all at once." And as much as possible, all from one source - Aircraft Spruce & Specialty. We're always playing a race against time up here (even in summer) and at $500.00 a month for the hanger I want to keep moving forward at all times. I already have the wing ribs from Charles Rubeck for a one piece wing and I am ready to order the complete spruce kit for the modernized Pietenpol from Aircraft Spruce & Specialty and have their material list for that. Now the question: What else do I need :-) In other words, does anyone have a complete and comprehensive parts list for "all" items needed (plywood, metal, fittings, etc., preferably with AS&S part numbers). It's not that I can't make sense out of the plans or parts list in the manual but it seems that the two may vary (the one in the manual seems to be for the original Aircamper and the plans for the modernized - am I right here?) I simply want to make sure I'm right as much as possible before ordering and shipping. I intend to follow Mike Cuy's plane almost to the letter with the exception of adding a second fuel tank and one piece wing vs. 3pc. Also, "anything" pre-built I am a definite candidate for and I will go that route when available. What and who is out there in that regard? Talk about a couple of loaded questions huh? Attached are a couple shots of what one day the Bethel Belle will look like (I am not affilated with the charity by the way, it's just what it's all about). Stacy Clark Bethel, Alaska P.S. Thanks Mike for the video I've watched it about ten times so far. Love the phrase, "...and the music comes out here." (lol) Also, if anyone sees Charles Rubeck tell him all arrived well and "thanks," and if the plane is half as strong as his shipping crates I should be able to fly into a brick wall and walk away :-) There is only one greater thing than to believe in the impossible...and that is to achieve it -- Stacy Clark

    Subject: Re: Nose fuel tank design questions.
    --> Pietenpol-List message posted by: Rcaprd@aol.com Terry, and all, Fuel related problems account for the largest portion of engine failures, therefore a great deal of effort should go into the design of the fuel system. You should always assume that any time you re-fuel, that you also pumped in some water. A couple of years ago, Rex Hamilton (a high time pilot) was towing sailplanes out of Gliderport. He re-fueled, and took off with the next sail plane in tow, and at about 50' agl his engine quit. He released the tow rope, and peeled of to the left. The sail plane made an uneventful landing, but Rex hit the trees, and was killed on impact. There was over a gallon of water in the bottom of the fuel tank. Here are the pros & cons of my fuel system: Cowl tank - Fiberglass, Polyester resin, 10.7 gal, 1/4" copper tube J.B. Weld into the filler cap and bent to face into the wing, along with a cork float and wire up thru a small brass tube J.B. Weld into the fuel cap, for a fuel quantity indicator. This all works very well, but I'm at the mercy of strict NO ALCOHOL in the fuel. West System Epoxy is not effected by alcohol. I recently used West System, and will never use Polyester again (especially for fiberglass fuel tanks), although it does cost more. I have a cable operated valve at the outlet of the cowl tank, mounted on the firewall. The cowl tank is completely separated from the passenger compartment, to prevent any fuel leaks from accumulating in the passenger compartment. I used 3/8" aluminum tubing / AN fittings throughout. The design of any tank should allow any water in the bottom to find it's way out to the gascolator, while the plane is static laden (normal attitude on the ground), so you can sump the water out of the fuel system. The gascolator must be mounted in the lowest part of the fuel system (to collect water), yet above the bottom of the fuselage, so if the landing gear is wiped out, it will not knock the gascolator off and cause a fuel leak. Wing tank - Fiberglass, Polyester Resin, 9.8 gal, 1/4" copper tube J.B. weld into the filler cap and bent to face into the wind. Things I would have done different - use West Systems Epoxy for the resin in the fiberglass. I extended the filler tube too far down into the the wing tank (about 1 1/2"). That was too far, and eventually drilled holes into the sides of mentioned tube, so I could put more fuel in it. A good quality ball valve re-plentishes the cowl tank when the wire gets down to a point I marked on my windshield. As for checking fuel flow at climb attitude, Tony Bengalis suggests checking it at the fuel hose fitting on the carb. I figured the fuel has to get through the needle valve, so I re-checked the flow to compare it to the hose fitting location. I removed the top of the carb, and held it above a calibrated container, and the needle valve restricts the flow A LOT !! However, it was still more flow than max fuel burn, even with only a gallon, or so, in the tank. I can carry 20 gal of fuel onboard, and I can attest to the fact that it IS possible to pee in a bottle, while flying a Pietenpol !! Come to think of it...that's probably something that very few people in history have ever done... Chuck Gantzer NX770CG

Another Pietenpol chick left the NEST! Hoop-de-do: It Flew, It Flew , It Flew!!! Three takeoffs and consequently, three landings. WHAT A RUSH!!!! >> And a Big Congratulations to you, Ken, for achieving this milestone !! Thank you for shareing it with the folks on the list. It keeps everyone all stoked up about our beloved design. Celebration is certainly in order, but then it is back to business. The first 20 hours of any homebuilt plane is the most crucial, and most dangerous. You are getting aquinted with an unfamiliar plane and characteristics, and this is when the gremlins will come out and Bite you !! It would be good to do a post flight brief with someone, and talk about every minor detail of the flight. Every flight must be followed by a thourough post flight inspection, and every pre-flight should be equilivant to an Annual inspection...which means every inspection cover, entire fuel system, a careful inspection of every fitting and cable, prop torque, and so fourth. It would be very beneficial if you would also have a competent assistant to re-inspect everything you already looked at. Plan each flight so that at any point during the flight, you have a place to land...probably a difficult thing to do in Alaska. 'Plan the Flight, and Fly the Plan'. Wait for near perfect weather. You'll pay more attention to what she's telling you now, as you get to know each other, and believe me...she will communicate with you !! It's something you have to experience to understand, and you, my friend, are experiencing it !! So, a Big YYEEEE HHAAAAWWW for now, but then go and triple check everything. And keep us updated on your progress. Brodhead is closer than you think... Chuck Gantzer NX770CG
