I'm not going to win this competition but the most annoying part purchase I've had is the elevator horn tks panel on my SR22T. An 8' long TKS wing panel costs about $2800. The 3" long elevator horn panel cost me $3820. I about threw up. I'm told the cost for the same part now is $5730.

I think $1600 for a piece of extruded ABS plastic that covers the emergency gear extension crank is pretty rich.

I won't win either but will play. $5,200 for an electrical modulator--half the size of an i phone-for prop de-ice boots on a Cessna Corvalis. I actually said I would have complained had a zero been dropped. That's in the box, unshipped, untaxed, and uninstalled. But I have a third party story also. A non-structural metal piece for the nose gear of a Cardinal RG was quoted by Cessna at $27,000. I didn't even put these numbers into my native Canadian currency to play fair.

In any Bonanza with cowl flaps there's a 12 inch long piece of half inch OD aluminum tubing with a pair of 3 inch long teardrop shaped stamped pieces of sheet aluminum welded on that translates the horizontal cowl flap control cable movement to a vertical linkage to the cowl flaps. Beech wants something like $12-15,000 to make you one.

I'm pretty sure I could build one for a lot less even including the purchase of a brand new TIG welder and a decent hourly wage for the two months it would take me to become proficient with the welder.

I suspect that price is at least partly intended to get you to do just that.

On the Mirage part, the sump drain should only... only be in the $270 range. If you are talking about the wing sump tank, it is actually a fuel cell, and while 12K sounds ridiculous, it is not a little piece of plastic but a complicated structure. Usually fails when someone pressurizes the fuel tank for some odd reason, like checking for leaks. Don't do that Are you a member of MMOPA? is your mechanic a PA46 specific mechanic? have you contracted the MMOPA maintenance hotline to inquire? and have you contacted the MMOPA ombudsman to confirm the pricing and seek help?

If the answer to any of those is no, for heavens sake man, stop now before someone reams you a new one. A Mirage is more like a Citation than a bonanza. It is complex, and has to be inspected and maintained correctly. So many horror stories out there about people going down a path that never should have been started. Good luck.

R182, Landing gear saddle (part that tubular gear plugs in to). $16k. We fond a “deal” on a tested good used one for $10k.

Not on a piston, but equally ridiculous. Passenger seat slide release lever on C90/200 (early version). Piece of bent 1/4” tube aluminum. Think brake line like tubing, bent in the shape of a “C”. Attaches to pins that lock seat in place. Pull up on “C” to pull up seat lock pins. $2100.

Its not just aviation. I was quoted $1500 for a new neoprene seat cover on my 2011 Nissan Xterra.
