If [BLANK] is what you find too expensive about flying...

[Bell206]

The one thing people continuously seem to forget is that the whole “certified” side does not revolve around only the private, recreational aircraft owner. Rather its whole function is based on international standards and agreements.

And since Cessna and Piper sell parts globally and not only to that small subset of private owners, these certified rules allow that to happen seamlessly with zero additional certifications from other countries. Same with any aircraft, engine, or prop made in the US.

A quick look at the TCCA Owner Maintained category aircraft is a prime example when those international agreements and rules are not followed.

However, there are a number of work arounds when it comes to keeping costs down. One is go E/AB. Two is look into repairing what you have just as shown with the $1 switch vs $900 switch example above. Then there’s AC 23-27. And so on. The main problem most owners won’t pay a mechanic to see if it can be fixed or look for replacement options.

But then again its probably cheaper and easier for owners to simply beech and whine on a public forum than try to save themselves money and blame someone else.

Yes.
And just to add, post 43 is a classic example on the lack of knowledge of the aviation system that exists among private aircraft owners.

 

[WDD]

So how can the company not then sell that $1 switch to anyone except Piper?

 

[MauleSkinner]

The ones they don't own directly, they issue ultimatums to: either produce parts solely for us, at the price point we dictate, or we'll never buy any parts from you and your business dies as the majority of planes on the market become off-limits to you.

Or there is some form of intellectual property in the part that is owned by the aircraft manufacturer, and it would be illegal for the part producer to sell it to anyone else.

So maybe the Certified regs need to have a sunset period, including patent/drawings. No reason a 1968 C172 should have any parts that aren't able to be procured from numerous suppliers or a local machine shop without having to jump through "owner produced parts" bs. Maybe the regs should say all Certified aircraft should be required to use "certified" parts for 25yrs, after such time the aircraft reverts to an owner-maintained status and LKQ parts can be used/sourced. All parts drawings/specs made available. It's essentially treating it like a classic car at that point. Just tossing stuff out there.

I don’t believe there’s anything stopping Auto Zone from developing/selling a compatible part, other than the same lack of return on investment that the manufacturer is dealing with.

[MauleSkinner]

Or me from making and using a duplicate part in my basement?

Correct. You’d just have to get a PMA for it if you want to sell it.

 

[Half Fast]

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 sometimes required special testing or screening.

You could buy the same part under the vendor’s own part number, but not under our number, pay less, and take some risk on what you were actually getting.

I can certainly believe an airplane manufacturer might do the same thing, and the part called out in the IPC will be their proprietary number and therefore you’ll be required to use it. If you can learn the standard part number, though, and if the part is made under some industry spec (SAE, for example), you could switch to it as a standard part.

Alternatively, you could produce a drawing for the part, procure it to that drawing, perform your own quality inspection, and call it an OPP.

 

[SoonerAviator]

Well, patents already expire, so that's not the limiting factor.

Imagine a casting or molding tool that costs $50,000 to build, and has a minimum run quantity of 1,000 pieces. Who is going to fund that tool and pay for the inventory to be able to sell parts for the existing planes?

Opening it up sounds really good, but our volumes are a couple of orders of magnitude too low to support a business in the same vein as classic Ford/Chevy replacement parts.

I realize that we're not likely going to be producing $30K molds to produce 10 parts. However, if a part can be machined from bar stock/forgings and be just as good, you will pay a premium but potentially not be locked into one supplier who refuses to make more parts without a 10-100pc demand.

 

[MauleSkinner]

Another thread killed by people stuck in their opinions. You have zero evidence the $1 switch is under any kind of IP protection. You are pretending that companies don't hold suppliers to exclusivity contracts as part of standard practice. Doesn't require any IP or any of that BS, all it requires is having a big customer base and threatening to deny access to it. Go ask a KFC franchisee why they can't serve Coca-Cola and maybe you'll figure out how the world really works.

Or just keep ****ting on everyone trying to make aviation more accessible if they dare to challenge any of the many sacred cows you blindly worship, that seems to be working out real well.

Actually, several people have encouraged those who think the prices are unreasonable to create an alternate supply chain, and have noted a couple of ways that it can be done.

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 selling their products to other restaurants, nor from selling to the general public.

In a 36 year career in aerospace I never once saw anything close to what you're describing. What really happens (and I suspect what might be the case with the $1 switch) is something like this:

We select a part, say a Vernitron potentiometer, for an application but we need a better accuracy. The standard catalog part has a +5% accuracy spec, but we need +1%. Some subset of Vernitron's pots will meet that, so we prepare a specification control drawing (SCD) that calls out the Vernitron part number but imposes a tighter accuracy spec and calls out a screening process. We then buy our parts by ordering our own SCD number part and we thereby get the higher accuracy pots. And they cost a lot more due to the special processing and quality control.

Now, Vernitron can still sell their standard parts as they please, but they can't sell parts under our SCD part number. We paid to create that SCD and we own it. Vernitron can, if they choose, even begin offering +1% accuracy parts as an option under their own catalog part number. But the part number called out in the parts list for our product is the SCD part number, and if you choose to repair our product by replacing that pot you will have to buy our part number to be legal. It's the only way my company has to be assured that you're getting the correct high-quality part needed.

Now, for our airplanes, the FAA allows us to buy "standard" parts instead of the part number called out in the airplance IPC, if the standard part is equivalent and if it is produced in accordance with a known and accepted specification, like an IEEE spec or an SAE spec or similar. If the $1 switch is made to such a spec and can be procured that way rather than using the Piper part number, fine, you're good to go. Otherwise you're stuck.

 

[hindsight2020]

Remember, some of these guys made a living being remoras to that status quo (ditto for the Aeromed lackeys). They're going to reflexively simp for it. So that's par for the course.

On a personal level, I'm just surprised EAB allowances remain untouched in this regulatory environment. I fear for the day they come for it. MOSAIC isn't gonna fix the exclusionary economics that keeps this hobby on life-support, anymore than the original intent of LSA ever did.

All that said, the amount of scoff and pencil whipping in fac built land would shock you. People pearl-clutch about it, but just like tax evasion in high tax jurisdictions with a high level of poverty (ask me how I know), on the record I don't condone it.... but I understand it

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 aircraft to be maintained like SLSAs (and I'm skeptical it will), that will be a big step forward.

Not this switch. I looked at it myself. Of course between my dad and I we've only been in the electronics industry for a combined 80 years. So what would we know about switches and electronics.

[Half Fast]

This, precisely.

In electronics it's "bin sorting". A component may have a manufacturing variance of, say, 10%, and gets sorted into performance "bins" of 1% each. You need and spec the 3% bin ("Suffix "C"), because it has been selected to match other components on the board.

Now, 5 years later, you find that you are the only manufacturer still buying that part. You've been paying $5 each. Then, the supplier runs out. Turns out, though, that since you are the only purchaser buying the part, they have thousands of each of every other bin code, which they have priced at $0.05 just to get rid of them. In effect, you've been paying $5 for a $0.50 part because you're only taking 10% of the production run. What's worse is that now that there are no more "C" suffix parts left, you have no choice but to either (1) pay the foundry for a full run of the entire line - 5 years' worth of all 10 suffixes - or (2) re-design your board to accept a different bin, which means re-certifying and probably forces dealing with other obsolete components. Option 1 means buying a full run of an otherwise obsolete part, which forces you to charge a huge price to account for the inventory carrying cost and paying for a whole bunch of parts that nobody else will ever consume. Option 2 means obsoleting your existing products that are in the field, and never having the ability to repair any of them, forcing a replacement with an expensive "new design" that has backed you into the corner of a limited availability, expensive component.

Ask me how I know about this situation...

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 they sift out the 3% parts to sell to you and you get NONE of the 1% parts. All your parts are between 2% and 3%.

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 cycles, etc., etc. All sorts of possibilities.

[Bell206]

o how can the company not then sell that $1 switch to anyone except Piper?

They can and do as well do other companies in similar situations. The issue is you need to follow one of the prescribed regulatory routes to use that $1 switch that preserves or alters the certified status of the aircraft as indicated in Block 6 of the AWC. Everything is interconnected in aviation as it is considered a closed system even on an international level.

Or there is some form of intellectual property in the part

FYI: never ran across any IP issues with aviation items at this level. As I recall there is a disconnect between aviation and standard IP laws. I believe it was a result of the infamous patent wars initiated by the Wright Brothers. For example, the lack of IP protection is what spurred the FAR requiring a permission letter to use an STC to protect the STC holder. But someone could still copy it provided they obtained their own approvals.

So maybe the Certified regs need to have a sunset period,

Then you would have to either rewrite every international aviation rule/standard/agreement to allow that or remove those aircraft from those rules/agreements like TCCA did with the owner-maintained aircraft: the aircraft and their products can never be exported from Canada as a certified aircraft or part. Those aircraft are not even allowed to fly in US airspace but C-reg E/AB are.

I don’t believe there’s anything stopping Auto Zone from developing/selling a compatible part

And there’s nothing that will stop an owner from installing that Auto Zone part. You can do it now provided you follow the proper route. Been that way for eons.

f MOSAIC allows certificated aircraft to be maintained like SLSAs (and I'm skeptical it will), that will be a big step forward.

I think the most interesting part of the current MOSAIC NPRM was where they shifted the LSR-M curriculum to the ACS standard. This is the same standard used for an A&P. You want an A&P-Lite certificate that means something this is the route it needs to take.

 

[Bell206]

Or just keep ****ting on everyone trying to make aviation more accessible

But it is accessible. At least to those who take the time to learn how the aviation system works. Since its obvious you have limited knowledge perhaps change your aviation learning path to one less regimented?

Experimental/Amateur-Built frees you from most rules except when flying only. Basically the sky’s the limit. Want more freedom follow Part 103 and you don’t even need a certificate. Want more structure then S-LSA aircraft can work and you can even work on them after 120hr school.

Or you can go somewhere in between and take a C172, slap a GM V-8 on it and fly it under Experimental-Exhibition. No problem.

So yes aviation is very accessible even to those who think its not.

 

[ateamer]

Textron not only owns most of the airframe manufacturers, they also own most of the available supply of engines and many, many other parts.

When did Textron buy Piper, Cirrus, Diamond,mTecnam, American Champion, and about 69 LSA manufacturers? What about Continental and Rotax?

 

[DJTorrente]

Question:

Do you believe that Textron's profitability is excessive, based on this sort of situation? Why or why not?

I think that neither I, nor anyone, should get to decide what is "excessive" profit. After 275 years, Adam Smith (of "Wealth of Nations" fame) is STILL right. Command economies have collapsed everywhere they've been tried -- to say nothing of 100 million people slaughtered because they were inconvenient to Marx's greater vision.

I shouldn't have to look under the hood of Textron's cost structure. There's too much incentive and ample opportunity for them to hide the ball. If the market clearing price of a given part includes profit above marginal cost, there is incentive for competitors to undercut the incumbents -- until regulatory restrictions stop them. Regulation is a subsidy to the incumbent, who is invested in the status quo, and is better able to absorb the cost of regulatory compliance than a challenger.

 

[ateamer]

Indeed. Out of the top ten selling new planes in 2023, only one was from Textron. It was not the highest seller.

[Bell206]

there is incentive for competitors to undercut the incumbents -- until regulatory restrictions stop them.

But if that were true then the PMA and similar industries should be flat or declining. Except they’re not. Some of those industries are actually "booming." However, the qualifier as with any product is the market in which they serve and the private Part 91 market is not one of those.

Regulatory requirements have always been a cost of doing business vs a restriction. Have been procuring parts for a very long time from many different sources and do not recall any vendor ever implying they cancelled or didn’t pursue a product due to regulatory issues. No profitable market, all the time.

There were even times when some vendors would retool for a discontinued part provided we ordered a minimum to meet their profit minimums. So I don’t know where people consistently get it’s a regulatory hinderance. That is not my or others experiences at all.

Even at the aircraft certification levels, OEMs are still certifying new aircraft for viable markets. Both Cessna and Beech have provided 2 clean, sheet aircraft in the past 5 years. No regulatory restriction holding them back to include GE with their clean sheet engine design for one of them. But you won’t see one for the ever-declining Part 91 recreational market. Simple economics.

 

[WDD]

In the hard core hunt for a 182 now - M,N,P or Q model. Looking for something with a mid time or younger engine, won't have a $15,000 annuals for the next 5 years, and won't have a wing fall off while flying it home after buying it. Looking at paying about twice what I paid for my first house, and then putting a third of that again into modernizing the panel.

And good grief it's not easy. When you look at the log books, and then if you get one into pre buy........ yikes. My A&P is fairly pragmatic - he's not a "the cup holder is scratched, where is the AD on that" kind of guy.

And perspective. This is a first world problem, I'm blessed, just be patient. But this does give me more time to pick up more tips from this place on how to buy, etc.
