Pietenpol-List: let's get started; odds & ends

1. Dick writes->I would also like to hear more about icing problems that list members>have experienced.How about a plain-Jane Skylane, VFR on a summer afternoon at about 8500 MSL, trimmed for cruise and enjoying the sights on a cross-country, when the engine started sputtering and losing power? Do you have any idea how quickly you can get behind the airplane when it sneaks up on you like that? ;o) I checked and rechecked everything, prop, mixture, throttle, cowl flaps, windows and doors, fuel selector valve, every gauge and dial on the panel... then remembered that little square knob and pulled it but not before losing significant altitude and all of my composure. Whew! Power again! So even the most common and popular, best-engineered, certified-engined spam cans can develop carb ice on the nicest of summer days at cruise power. Don't sit there and try to work your way around providing carb heat on a non-injected airplane engine... aero carb or not (my opinion!)2. Ken asks->Question what do you do for carb ice if the heat is already on.What was it they said... "drop a brick and watch where it lands, because that's where you will be in about 30 seconds" ;o)3. DJ writes->I am using the skytek struts. I'm using the smaller size for the cabanes>and the larger for ift struts.For those who have built their struts out of round tubing (or you're planning to use round tubing to save money), you can still streamline them using the plastic slip-on material the ultralight guys use. Available at http://streamline.8k.com/ and just think of the speed you'll gain by reducing all that drag!4. Jim asks->I've seen a few different suppliers of plans and I'd like to know the >difference between them.This was one of my first questions when I started looking at the Pietenpol, and I think you've pretty much gotten the answer you need: get the true-blue plans from Don Pietenpol, and get the manual too. I also got the Flying & Glider Manuals through EAA, which are reprints of the original articles that Mr. Pietenpol wrote and add an interesting narrative to the project. The one to avoid is St. Croix Aircraft, which (I understand) simply copies and sells the Pietenpol/F&G plans. As a point of interest (Mike Cuy, are you listening?), I just looked at http://www.ultralightnews.com/plansbuye ... camper.htm and the St. Croix information is shown... with a picture of Mike Cuy's authentic Pietenpol! I think this should be taken care of immediately, since it's false and misleading and I know Mike doesn't intentionally support the knock-offs.5. Jack writes->take a camera with a lot of film and take pictures of every little>detail you can think of, such as how the jury struts attach to the wing and>the lift struts - jury struts aren't even shown on the plans so you can >find>lots of variation here.And the jury struts are one thing you WILL find mentioned in the Pietenpol construction manual, but without any detail. For a really nice rendition of the jury struts (and more information about John Dilatush's Piet in general), see my webpage at http://www.flysquirrel.net/piets/John_piet.html6. Gene writes->everyone calls them Pietenpols, it took me a>while to figure out why some of the planes were so different.As far as the GN-1, as I understand it Mr. Grega distinguished it from the original Pietenpol by calling it "Air Camper" instead of "AirCamper" (two words instead of one), or something like that. A fine line, and now all but insignificant. Suffice it to say that there are many details and structural differences between the Pietenpol and the Grega, but the external appearance is very much the same to the untrained eye.7. Hank asks->Does anyone have a copy of a stress analysis that has been done>on the wood or steel tube Pietenpol?There was an analysis done on the steel tube, standard Piet fuselage, commissioned by Mr. Pietenpol. But as far as having a copy of the analysis, unless it's in Don Pietenpol's personal family effects from Mr. Pietenpol, I wouldn't think it would be around anymore. If you find it, by all means donate it to the EAA Museum! Regarding the analysis done by the British Piet guys, that may very well be available today but would likely take a bit of scrounging and may require conversion from pounds sterling to American greenbacks... or Whitworth to SAE ;o)Happy 4th of July, especially to our British friends!

Here is the list of EAA NH Chapters... EAA 917 Alton Bay, NH EAA 1314 Keene, NH www.whickertech.com/eaaeen.htm EAA 336 Nashua, NH http://home.earthlink.net/~archie97/ EAA 225 Rochester, NH EAA 61 Townshend, NH EAA 740 West Lebanon, NH http://www.eaachapter740.org EAA 1085 West Ossipee, NH I think West Ossipee is closer than West Lebanon. EAA 225 is a great little chapterbut it is even further away.Cy GalleyEditor, EAA Safety Programscgalley(at)qcbc.org or experimenter(at)eaa.org----- Original Message -----

Are there any members of the Pietenpol family or British Piet guys on thelist that can help? I know the analysis "could" be done again, but to do itright you need the loads analysis first and I haven't got that either (plus,even 30 years ago when I got my degree they weren't teaching ANYTHING aboutanalysis of wood fuselages. I'm using my fathers aero books from the late30s and 40s along with some ancient NACA reports to learn the "old way").Hank Jarrett7.

I know of no-one over here in the UK who admits to having carried out astress analysis of the wooden Piet. The only chap who may have come close isJim Wills who designed some built up spars some years ago that now form partof the UK plans. Unfortunately, Jim is unwilling to share details of hisspars outside the UK (and presumably any other associated information) infear of litigation should anything go wrong.We also have a metal tube fuselage option approved for use and built by PaulPrince of Aviation Metalcraft, but it bears little resemblance to the wayBernard designed his.PS - I'll coming over to Brodhead to claim that nice cup of tea. Should bearriving sometime Friday evening. Don't forget to put the kettle on...Alan James (G-BUCO)The UK Pietenpol Club--- Original Message -----

Alan James,What does PFA documentation say about brazing 4130?chris bobka----- Original Message -----

Chris,I am unable to confirm the PFA's view on the subject, and having had most ofthe parts welded, brazing has never been an issue. The only parts brazed onG-BUCO are the tubes passing through the cabane struts and similarly, thebearing tubes through the torque tube. Paul Prince of Aviation Metalcraft(makers of the UK Piet metal fuselage) confirms that he does the same.Alan James----- Original Message -----
