I am looking for a landing gear retraction motor, PN LA11C2114 for a 1976 Moony M20C, or someone that rebuilds this part.

Contact LASAR or Maxwell. They are extremely hard to get and service. If it's the electric motor, your AP could have that rebuilt by a electric motor shop. Gears are unobtainium at the moment, though it looks like a round of orders will come up within the next few months. A direct replacement is one of the Dukes actuators, not sure which model though (Maxwell knows for sure).

Also, make sure its the actuator and not something else in the electric system. Did they bench test the actuator? A lot of times the problem lies somewhere else (best case scenario too).

Good luck!

I've got a serviceable Dukes actuator here. It came out of my plane because I converted to the newer style. The Ovation-style retrofit interior and the side crank dont really go together.

Dear Sirs, 

We are an ANAC certified workshop in Brazil and we need technical publications (Service Manual and Parts Catalog) for Dukes Aerospace electric motor and actuator P/N: 4196-00-1C

If you can help us we will be grateful and please send us the price of the publications and we will pay you.

If you do not have the technical publications, at least get us an exploded view of the motor and actuator.

I am in the same boat.  I have a dukes 4196-00 and the motor shop cant get it apart.   They suggested buying a new motor.  Does anyone know how it comes apart?

Wow! Here’s your chance to buy a new gear set!! For the low low price of $5k!!!

Not sure if you read their post there 201Steve, but their problem is a bad actuator motor...try to find those, just as hard as the gear sets ;) then start pricing used actuators with no mention or guarantee as to the state of the gears or motor...so actually it's not that bad of a deal, especially if you are AOG (new motor and new gears) ...Mooney has licensed the gears to Lasar, any idea as to how much they are gonna charge for them, me either, but if it's like any of their other items it will probably be around $2500.... just offfering this up as a possible option for them to consider, I don't have a dog in the fight either way ;)

 No I understand. I don’t hate it a bit. Just being dramatic. If you want the gear set, here’s the shot. 
 

I did the exact same thing 3 months ago. Bought an actuator motor assembly (with 40:1 gears) for $5k. So now I have a fully working, complete system, with all parts in the event any of them fail. Call it a $5k insurance policy. I did not enjoy having to do it but I am now covered from getting grounded unforeseen. I don’t like being vulnerable or waiting on anyone to do their job. So, case closed for me.

Yep, it's about the ONLY part that you can't get that leaves you AOG for an undetermined period of time and the options aren't that cheap, revert back to J-Bar for about $7K or do the Eaton Conversion for not less that $16K...I was scared s#itless this annual as to what I would do if the gears failed, now I'm sleeping better knowing that's one less thing to worry about.

I have a Dukes style too as part with a bad motor.   Won’t run in a certain position.  
I found a working motor actuator and already on the plane.  

No idea where to get this extra motor rebuilt and tried calling multiple places people mentioned in old posts.

This part I do not understand. There was a guy (George?) in California that used to do them all the time. It’s just a basic electric motor. How is George the only guy in the world who knows how to work on motors? I can’t fathom this. Electric motors are in every airplane. Do they have unique parts that’s the issue? Seems like they would all be pretty standard to motor fixers no? What’s the deal?

George has been retired for some years, now.  In 2013 he overhauled my generator.  (I’ll wait for the engine overhaul to upgrade to an alternator, maybe 800 hrs away +-.)  I did do the Zeftronics VR at the time, though.

I finally figured out how to disassemble this actuator and separate the motor.   I took it to a shop in Knoxville to check brushes and test.    But if the winding is bad, I have another shop in Florida that will rewind the Dukes flap motor and actuator motor.  msg me if you want their info

Can't you just post who it is?

No you can not post this on the forum because aircraft parts require FAA oversight when they are repaired. So if the shop is not certified by the FAA they are taking a risk with their business. Many alternator repair places have gone through this.

I know this is a bit off topic...  but is there a category for vintage aircraft, warbirds for example where there are few left flying, that permits the use of "non blessed" parts or repair services?  Something akin to experimental aircraft but for originally certified aircraft?  I don't fully understand the owner supplied parts discussions but it's been discussed on MS.  Is there something similar for the overhaul or repair of parts?  It seems like there could be a turning point for vintage aircraft where something like this is required.

LOL, Like the oversight they do on Boeing ;)

An A&P can "supervise" a repair done anywhere, which is why electric motor and alternator shops are often recommended for such things.   There's no regulatory problem with this.   This is done for all kinds of things, like welding, etc.   "Supervision" includes inspecting the repaired item.

@DCarlton

https://www.faa.gov/documentLibrary/media/Advisory_Circular/AC_23-27.pdf

This AC applies to ALL Mooney’s regardless of date of manufacture.

Ref “supervision” the FAA would prefer me take an exhaust system to a professional welder and have it TIG welded than say for me to use my Oxy Acetylene torch and do it myself.

A problem can be if I held out that I Overhauled say an electric motor as that’s beyond my capabilities as an A&P/IA, however a repair is likely acceptable, to the FAA language is everything.

Basically, yes and no.  No from the standpoint that you can't put anything "non blessed" on a certificated airplane, but Yes in the sense that there has been a lot of interpretation and guidance on what "blessed" means, particularly for "vintage" or orphaned aircraft.  AC 23-27 is one example of guidance specifically provided for these cases. Additionally, there is a fair amount of room for creativity in Owner Produced Parts, and the ability to put a stake in it so that nobody makes you take it back off via the VARMA process, which is also specifically for "vintage" aircraft (it's the V in VARMA).   These are all FAA efforts to make it more practical to maintain aging or "vintage" or orphaned airplanes with little or no factory support.

All of this applies to part substitution, but can often be interpreted to apply to repair or overhaul, since the overhauled or repaired part could be considered a substitute for an original.   Your IA is the guy who's opinion matters on all this, since he's the one that signs the logbook.   VARMA is a path to verify that something that might seem sketchy may actually be approved, so that an IA with a different opinion doesn't make you take it back off later.

Coordination and cooperation with your IA is key, since they can even "supervise" you doing the work and then sign it off if they're satisfied that things were done correctly according to the regs and various guidances.   Some IAs are much more flexible on this than others, since some of it does require interpretation or understanding of the various regs and advice.   We've been a bit surprised sometimes on how pragmatic the FAA reps can be on this during public presentations, so it really does need to be done carefully in consultation with the people you work with (i.e., your IA).

So, imho, you can get there from here, but it isn't always easy, and it takes being careful about navigating the regs and guidance in a way that is supportable for whatever you're trying to do.   My personal standard is that if I'm okay with standing in front of a judge explaining why I did something, then that's a reasonable path.
