Brodhead Pietenpol Association

UNREPENTANTWell, if the guy has "vast model building" experience, he must be right.Actually, across the pond, over in Great Britain, the rules are much more strict,regarding amateur built aircraft. To build a Pietenpol in the UK, you mustfollow the approved set of plans, which have been analyzed for structural integrity,and modified in certain areas. In the UK, jury struts are mandatory ona Pietenpol (but only on the front strut, for some reason).Put 'em on.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 23 May 2013 11:58:00 -0500Subject: Pietenpol-List: anyone have an extra set of tail plans?

The best I've heard upon telling a Captain I'm flying with that I want to builda Piet was...Awesome, all you have to do is:Change the airfoil (Clark y, by the way), wing size, construction and position.Totally different strut arrangement.Use a different engine than I've ever even heard of being on a Piet.Change the control system to push rods.Change the fuse length width arrangement (cockpit sizes, seats, etc)Change the size of the tail feathers.Change the gear arrangement.and a dozen other minor things...It sounded like a nice airplane, I'm just not sure why he thought I should stillcall it a Piet! Uh, well, because you can keep the general shape the same andit'll kinda look like a Piet.All good and to each his own, but wow.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: anyone have an extra set of tail plans?

Why don't you try contacting Andrew Pietenpol directly? If you explain when youpurchased your original set of plans, and explain what happened (how you lostthe tail plans), he might make a price just for those tail plans and send themright out to you. Just a thought.--------Semper Fi,Terry HandAthens, GARead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: fuel flow test

Rick,You can find the following information in AC 90-89A, "AMATEUR-BUILT AIRCRAFT ANDULTRALIGHT FLIGHT TESTING HANDBOOK"Here is the link-http://www.faa.gov/documentLibrary/medi ... 9A.pdfJust so you don't have to search for the info, I have included the appropriatesection below-Section 11. Additional Engine Tests, Paragraph 1e., Page 23Fuel Flow and Unusable Fuel Check: This is a field test to ensure the aircraftengine will get enough fuel to run properly, even if the aircraft is in a steepclimb or stall attitude. (1) First, place the aircrafts nose at an angle 5 degrees above the highest anticipatedclimb angle. The easiest and safest way to do this with a conventionalgear aircraft is to dig a hole and place the aircrafts tail in it. For a nosegear aircraft, build a ramp to raise the nose gear to the proper angle.(2) Make sure the aircraft is tied-down and chocked. With minimum fuel in the tanks,disconnect the fuel line to carburetor. The fuel flow with a gravity flowsystem should be 150 percent of the fuel consumption of the engine at full throttle.With a fuel system that is pressurized, the fuel flow should be at least125 percent. When the fuel stops flowing, the remaining fuel is the unusablefuel quantity.(3) Since the fuel consumption of most modern engines is approximately .55 poundsper brake horsepower per hour for a 100 horsepower engine, the test fuel flowshould be 82.5 pounds (13.7 gallons) per hour for gravity feed, or 68.75 pounds(11.5 gallons) per hour for a pressurized system. The pounds per hour dividedby 60 equals 1.4 pounds and 1.15 pounds per minute fuel rate respectively.NOTE: Formula for fuel flow rate gravity feed is .55 x engine horsepower x 1.50= pounds of fuel per hour divided by 60 to get pounds per minute, dividedby 6 to get gallons per minute. For a pressurized system, substitute 1.25 for1.50 to determine fuel flow rate.This document just gives you the logic behind the test.Hope it helps.--------Semper Fi,Terry HandAthens, GARead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 23 May 2013 19:49:57 +0000 (UTC)
