In certified aircraft, specific hardware is included as part of the type certificate. Hardware that meets the same specifications as original are to be used, even if it is stainless steel. In some certified aircraft, certain particular stainless steel hardware has been used. I know of the reasonably wide use of A286, an iron, chrome and nickel alloy, due to his high strength and relatively high toughness. The thing that's important in certified aircraft is to use the specified hardware for that particular application - and sometimes it will be stainless steel. David Paule ----- Original Message -----

Pietenpol-List: Plans on E bay

Subject: Pietenpol-List: Plans on E bayRan across this on e bay if anyone ins interested with drawings for the biplane version.item number 290382001867These drawings could be framed and hung on the wall like art. There are 8 pages of 18"x24" blueprints for the Aircamper or Sky Scout.. Also included are the supplemental drawings ( 3 pages) for the construction of the bi-wing version. This supplement includes full size drawings for the wing ribs. The Aircamper is an all wood, two place airplane designed for easy building and fun flying. Included is supplemental drawings for a longer fuselage version if using a lighter engine than the original. The plans also include the conversion of a Model-A Ford motor for aircraft use.These plans have beenin my closet for 20 years and never used or even looked at in that time. These plans plus supplemental sell for $160.00, but I will start the bidding at $50.00. Thank you for looking and good luck. There is shipping and handling fee of $15.00.John________________________________________________________________________________

In general, the suffix "C" means 300 series stainless, and it's not nearly as strong as the standard hardware. If you find stuff with the suffix "N" it's probably the good A286, with a strength of 160 ksi, very good stuff. I hesitate to post this because I don't know that the "C" and "N" suffixes apply generally or if they sometimes mean different things. So be careful out there and check the specs yourself.But it's usually so expensive that even the aerospace companies, that use it in large quantities, complain about the cost.Worth mentioning: If you are installing a nut that is self-locking, and you need to put a specific torque on it, that's in addition to the running torque. You've got to measure the running torque before the nut seats and add to that to the spec torque. In most cases, though, you don't need to torque to a specification. This only applies to those cases where you do.>From personal experience with a 54 year old Cessna, I can say that AN hardware is remarkably durable and that provided that ordinary care is taken, perfectly satisfactory. My airplane still has some original hardware externally, and it's still airworthy. No longer shiny, to be sure, but airworthy still. The interior hardware is entirely sound, and in some cases isn't even tarnished.If I were building a Pietenpol, I'd ignore the lure of stainless steel where possible. It would only add to my difficulties. What I'd try to do is keep the types of hardware to a minimum, using AN (and NAS and MS) hardware where I could. David Paule ----- Original Message -----
