What regulation requires a 400x markup on switch prices? Beats me; I use a Norelco.

Is the part number a Piper part number, or a switch manufacturer part number? You might not be able to tell if there's something special just from looking at the switch. It could be screening for contact resistance, for no ignition of a flammable atmosphere, lot sample screening for number of...

BTDT. This situation is why we do lifetime buys on certain critical components. And that costs. And if you were counting on, for example, a Gaussian distribution with 3-sigma = 3% in your monte carlo circuit analysis, forget it. What you really have looks more like a slice from a volcano, as...

Actually, from a regulatory standpoint, most of what I've seen the FAA doing is aimed at keeping the old birds flying. Things like OPP and allowing substitute parts and the new VARMA are steps in the right direction, but the FAA's pace is unfortunately glacial. If MOSAIC allows certificated...

Looks like it's still at VAC, on loan. https://www.valiantaircommand.com/portfolio-collections/korean-war/xp-82-twin-mustang

Nice. I saw that plane in a hangar at Valiant Air Command in Titusville last year. It was having some work done on it, and I understood it was for sale at the time.

Oh brother. There's so much confusion in this it's hard to know where to begin, and I'm not in the mood to write a treatise for you. Look, if KFC sells only Pepsi, it's because they agreed with Pepsi not to serve anything else in order to get favorable pricing. It does not prevent Pepsi from...

My company frequently bought off-the-shelf parts from a supplier using a spec control drawing with our own part number. This meant that we always knew exactly what we were getting and that the supplier couldn’t change the part’s specifications without notice and concurrence. Our drawings also...

AFAIK, there's no reason we can't do both. :biggrin:

Try Dianne’s next time and tell me what you think.

It’s the same list. #3 actually contains two, since there’s an “or” statement separating fabrication processes and assembly methods.

It's been done. For the part to be "Owner Produced" the airplane owner would have to provide you with data to manufacture the part. You could, for example, provide him with a partial drawing of the part which he would then complete, adding his N# at least, and the owner would then send you...

Hmmm... I counted six. Participating in the design of the part can include supervising the manufacture of the part or providing the manufacturer with the following: the design data, the materials with which to make the part, the fabrication processes, assembly methods, or the quality control...

Ah, therein hangs a tale, and it’s bit more complex...... https://generalaviationnews.com/2020/03/18/questions-from-the-cockpit-a-pointed-question/

???????? From everything I've read on the subject, Boeing's decision not to make a clean sheet design and to go with MCAS was a marketing decision to compete with Airbus. Design decisions all along the way were made for financial reasons.
