Idea to get some FAA/PMA parts support

[bmcconnaha]

  I have been in contact with Mcfarlane after reaching out to Mooney on several parts i need and not having any luck.  the main thing i really need is a Plessy no back spring.  Mcfarlane was very receptive and put me in touch with thier engineers.  They asked me to compile a short list of needed stuff that the factory isnt supplying any longer.  I think the best start would be any repetitive SB that should be complied with, but doesnt have parts to do so.   let me know, and i can pass the info on.  Thank you

 what  part are you referring to ?

I am after the Plessy no back spring.  I am getting a list of other parts that are needed, but not supported from the factory.  I started this to get ideas what others need.

The cowl boots for the Cs and Es.

Gear sets for the Duke gear actuators.

Everybody keeps talking about this. You finally did something about it. Thank You for doing that!

Why not look at the Eaton spring as well? Some rod end bearings are difficult to get from time to time.

Not sure if the ones for the F are any different, but that’s one of the few parts that worries me!

Or the pushrods themselves, but that's probably further down the 'druther list.

Gear limit switches?

I finally found the gear switch after buying a couple of the wrong ones, for anyone that needs one it’s an MS24659-23D 

readily available, can even get one on Amazon, I suspect the gear limit switches are the same, but don’t know

Yes, the drawn tapered steel tubes for landing gear with welded rod end bearings.

Probably jack screws at some point in the near future, if not already.

So how would Mcfarlane build all these different parts without the Mooney factory handing them the specs for each?

Heard this from several people including service centers.  
can anyone get me part numbers?

Per the IPC, those air induction couplings are Mooney P/N 600064-000 for the M20C/G, and 600115-005 for the M20E/F.

They recently started making engine control cables available to Mooney part numbers, but they were the OEM for those, anyway.   They clearly have PMA already, and if they started offering other parts I don't think I'd be the one to rock the boat and ask any questions.   

Might not be much different than Lasar making nose gear trusses that are different than the factory units.

Sent you a PM last night, did you get it?

Gear discs.

heim rod end bearing for mixture cable.

Most airframe parts it’s easy, you determine the alloy and then simply duplicate. However many of the parts being discussed like heim joints etc are purchased parts, sometimes modified, but usually the mod is self explanatory, No-Back springs as has already been discussed are of course purchased parts.

So Mcfarlane who we assume isn’t on credit hold, buys parts, inducts them into their QC dept and Voila you have a PMA part.
We in many cases don’t need PMA parts, for instance the MS number of the landing gear switch sourced from Amazon makes it legal, but many A&P’s are hesitant installing a  non PMA part so it helps if the part comes in a box marked PMA.

One assumes Eaton for instance won’t sell springs to you or me, but likely will to a PMA holder, Eaton doesn’t make aircraft parts and knows better than to sell their parts directly as aircraft parts, a PMA holder can and does take standard parts and “make” them aircraft parts.

Yeah, it definitely wouldn’t be me rocking that boat!  I just don’t want to get my hopes up that someone will help us if it’s not possible..

All it takes is a PMA to make an equivalent part. It takes an STC and PMA to make a better part.

Decades ago, Rapco Aircraft made landing gear shock discs, they didn’t last very long before they stopped.  Barry Controls the other engine mount manufacturer might be a candidate now.

I am a little hazy on what is required for a PMA. Some of the posts seem to be implying that the fact McFarlane has a PMA they could begin manufacturing other Mooney parts if they wanted to. I thought EACH part had to have a separate FAA issued PMA for THAT specific part. I'd love  to be wrong on this; set me straight!

Also, as a potential manufacturer I would be very concerned with products liability, especially with a critical single point of failure part like the no back spring. How big is that market and, ultimately, how much profit is to be made vs the risk/premiums cost.

A lot of getting PMA status is setting up the processes and controls for traceability, etc.   Once that is in place, adding on additional items becomes easier, especially if they're similar to other items you already have relevant processes for.    Since McFarlane already sells Mooney-specific parts under Mooney part numbers, and a ton of other stuff to boot, they seem like a good candidate for picking up anything else that they might be interested in.   The fact that it is reported that they've shown interest, assuming we got that right, seems promising.
