-- Pietenpol-List message posted by: "Bob Seibert" SOME THOUGHTS BEFORE FLYING Keep the aeroplane in such an attitude that the air pressure is directly in the pilot's face. - Horatio C. Barber, 1916 When a flight is proceeding incredibly well, something was forgotten. - Robert Livingston, 'Flying The Aeronca' The only time an aircraft has too much fuel on board is when it is on fire. - Sir Charles Kingsford Smith Flexible is much too rigid, in aviation you have to be fluid. - Verne Jobst If you can't afford to do something right, then be darn sure you can afford to do it wrong. - Charlie Nelson Just remember, if you crash because of weather, your funeral will be held on a sunny day. - Layton A. Bennett I hope you either take up parachute jumping or stay out of single motored airplanes at night. - Charles A. Lindbergh, to Wiley Post,1931 Never fly the 'A' model of anything. - Ed Thompson Never fly anything that doesn't have the paint worn off the rudder Pedals. - Harry Bill Keep thy airspeed up, less the earth come from below and smite thee. - William Kershner When a prang seems inevitable, endeavor to strike the softest, cheapest object in the vicinity, as slowly and gently as possible. - advice given to RAF pilots during W.W.II. Instrument flying is when your mind gets a grip on the fact that there is vision beyond sight. - U.S. Navy 'Approach' magazine circa W.W.II. Always keep an 'out' in your hip pocket. - Bevo Howard The Cub is the safest airplane in the world; it can just barely kill you. - attributed to Max Stanley, Northrop test pilot A pilot who doesn't have any fear probably isn't flying his plane to its maximum. - Jon McBride, astronaut If you're faced with a forced landing, fly the thing as far into the crash as possible. - Bob Hoover It occurred to me that if I did not handle the crash correctly, there would be no survivors. - Richard Leakey, after engine failure in a single engine airplane, Nairobi, Africa, 1993. If an airplane is still in one piece, don't cheat on it. Ride the bastard down. - Ernest K. Gann, advice from the 'old pelican' Though I Fly Through the Valley of Death I Shall Fear No Evil For I am 80,000 feet and Climbing. - sign over the entrance to the SR-71 squadron on Kadena AB Okinawa You've never been lost until you've been lost at Mach 3. - Paul F. Crickmore The emergencies you train for almost never happen. It's the one you can't train for that kills you. - Ernest K. Gann, advice from the 'old pelican' If you want to grow old as a pilot, you've got to know when to push it, and when to back off. - Chuck Yeager Never fly in the same cockpit with someone braver than you. - Richard Herman Jr, 'Firebreak' There is no reason to fly through a thunderstorm in peacetime. - Sign over squadron ops desk at Davis-Monthan AFB, AZ, 1970. An airplane might disappoint any pilot but it'll never surprise a good one. - Len Morgan ________________________________________________________________________________Date: Sun, 07 Oct 2001 12:07:24 -0500

Pietenpol-List: Tail Section Fittings

I have just finished making the metal fittings for my tail section, and Ihave a couple of questions, particularly for you guys who have finished yourplane:-For the wire brace fittings, did you bolt the fittings directly to the mainand center beams so that the fitting, except for the connection tab, will beunder the fabric covering? Or did you put a spacer under the fitting tobuild it up flush, and bolt the fitting on top of the fabric so it isexposed?-Same question for the elevator and rudder control horns. The plans for thehorns show a 1 inch opening, but do not show a spacer to build the main beamup to that thickness.It seems that putting all of these fittings flush on top of the fabric willhave a lot of bolts and nuts showing and produce more drag. Does it matteraerodynamically or aesthetically?Thanks as always for the help.Al Swansonswans071(at)tc.umn.edu________________________________________________________________________________Date: Sat, 6 Oct 2001 20:51:08 -0500

Thanks for the THOUGHTS BEFORE FLYING. I teach flying at the Univ. of Illinois.I'll use some of the quotes in my CFI groundschool class to help put things inperspecive. Dave Boyd

Alan,I used maple pieces (shims) to come flush with the fabric on my Pietenpol. The fittings were then installed on the out-side of the fabric surface. It is important to use a marinequality sealing or bedding compound between the fitting and the fabric to prevent water intrusion past the bolts. Try-ing to get a good covering job around previously-installedfittings with projecting lugs is difficult, but not impossible. Iprefer to have the fittings exposed where I can keep an eye on them. The added drag won't be noticeable.On the subject of these fittings, I did depart from the plansby using a single AN3 bolt to mount the horizontal stabilizerfittings to the main and rear spars. This allows the fittings toline up with the tail bracing wires (I used 3/32" SS cable onmy a/c), thus avoiding eccentric loading. To do this, it is ne-cessary to have the fittings outside the fabric. The single AN3 bolt is ample for this purpose. Cheers,Graham________________________________________________________________________________

Kirk,I went and looked at Dale and Greg's fittings. They really look nice and Iam building mine the same.I wonder if might know the answer to this question. If you build tailfeather fittings like theirs when do you bolt them on? Before covering withthe bolt underneath or after covering with them laying loose until you puncha hole to put the bolt through?Thanks, Ted----- Original Message -----

Ted,Build the pad underneath the fitting location flush so that when the fabricgoes over, it looks like nothing is there. Then when all the painting isdone, add the fittings and bolts and nuts. It should not be flush with thesurface. It will be nearly impossible to put fabric into a depression forthe fitting and hardware. Putting the fitting and hardware on after thefabric is finsished makes it much easier to do the covering and it is easierto inspect during your airworthiness inspeaction with the FAA/DAR and forinspecting forever afterward.chris bobkatech counselor----- Original Message -----

Subject: Re: Pietenpol-List: Tail Section FittingsTed,I fought that fitting problem but finally decided to build up flush with plywood, cover and place the small fittings out where it will be simple to attach. As far as drag is concerned, if one should be concerned on a Piet, I've an old can of Johnson's Floor Wax in the garage which will be applied generously throughout the airplane. I'll bet it will increase the A/S at least 8%. The holes are already drilled and fittings identified per position. Keep working so we can eat some good food.Corky, just coasting along in La getting things ready for the Fed man________________________________________________________________________________Date: Mon, 17 Dec 2001 09:32:52 -0600

Greg,My email server seemed to crash right after sending the message to the Pietlist. I just got on the archives and saw your response.I didn't do a good job of stating my question. Here is my real question. Ilike the way you have designed the horns. You have welded a channel to thehorn. The horns have to be under the fabric. So, my question deals withhow to attach the horns. Do you bolt them on before covering? Or, do youlay them loose, cover and then bolt them down? I hope this question makessense. It would be easier if we were both looking at the picture together.Thanks, Ted----- Original Message -----

Greg,OK, I now understand. Now, I have one more question. How do you fastenthem down? It would seem like if you use bolts the heads and nuts wouldbulge up under the fabric. Or do you use something like a rivet? Do thefasteners for the elevator horns go up and down (vertical) or forward andbackward (horizontal)?I really appreciate your patience. I am kind of thick headed sometimes.Happy New Year.Ted----- Original Message -----
