Yup... and the reason is because some engineer designed a $10,000 toilet seat.
I have nothing to do with the design of an aircraft toilet seat. But I did test them. That probably accounted for $5000 of it.

Were you testing them from a pooper or poopee perspective? ie sending or receiving.

There is a reason an aircraft toilet seat cost $10,000.
Never mind the exaggeration. :)

But you know those ashtrays in the lav doors? Little fold out stainless ashtrays?

$185.00 each.

Mostly testing and approving.

All aircraft parts...especially in the interior are tested for G forces, burn rate and toxicity.

It could be an off the shelf part from Home Depot....but until it's tested and approved and has documentation to back it....

Everything bolted down into an aircraft has to demonstrate it will not break off its mounts under acceleration forces that would occur in a survivable accident. The test is performed by pulling on the object in 3 direction at G loads specified by the FAA.

Yes and the ones in the Honda Jet are probably the ones used in an Acura. The Coffey pot in a Honda Jet was something like $18,000.

So AC system is now complete. With the exception that it really sucks. Still haven't figured out why I suddenly lost performance. I'm now thinking maybe my mono valve is leaking. I hate to replace that part because the only ones available are aftermarket MTC. I and many others have had significant problems with those. TBC

My grommet for the WW tank arrived with some 1.5" Al tube. I made a quick mock out of a 90° tube that I will be playing with mounting and plumbing solutions for the next week.

Don't worry about the welding.
When I have it all mocked up I will send it to a real welder.

Interesting. That’s probably why sometimes when I’m looking for electronics parts I will run across something like a potentiometer that for my needs is a $2 part whereas the top prices for components that perform the same function can be in the thousands.

E.g.: https://www.mouser.com/ProductDetail/Vishay-Spectrol/302C1102B01?qs=sGAEpiMZZMtC25l1F4XBU2wijbK1SzrXYmjMvhXO%2B4g=

Not a whole hell of a lot happening. I cant seem to get my head into working on the windshield washer until I get my AC sorted. I just got everything ready. I borrowed a recovery machine from my brother, got new filter for it, purged it out with nitrogen, changed my vacuum pump oil. All ready to go, then I found the recovery tank I got on E-bay had no DOT certifications or pressure test dates. So I sent that one back and now I have a genuine Robinair unit on order. I'm not fooling around. I also got a 30# cylinder of R134a. To get set up in auto AC today is very expensive. I'm getting pretty close. I really need to purchase my own recovery unit. That one I borrowed cost $100. to ship both ways. But next week I will have great charging weather, Mid to high 80's

So sooner or later I will purchase a recovery unit, but then new cars use a different Freon R1234, which requires a different recovery unit and tank.
