Any good "junk yard" sites to look for used avionics?

Any avionics you get from "junk yard" or salvage vendors will be "as is" will no or limited history. Your best bet is to contact some of the larger avionics vendors that also deal in the used market. While its dated info, I always had good luck with Bennetts Avionics in Connecticut with used equipment.
 
In the "used avionics" department, can anyone describe the process go get another STC to put used Garmin equipment back into a plane for use? Costs... worth it? Process? Just wondering if it's an easy process, or one that is more difficult than just installing new. Any insight and advice is greatly appreciated. Thanks for any reply and wisdom.
 
Wentworth Avionics is another good source. They always have a booth at SnF and Oshkosh if you attend either.

Avionics - Wentworth Aircraft

Avionics Used Avionics save money. When it comes to your aircraft, you want to have the best avionics money can buy.One way to make sure that you are able to get access to the best avionics is to purchase high quality, guaranteed avionics from Wentworth Aircraft, Inc. at a fraction of the cost...

Before you dive too deep in the avionics junk pile. Google AC 23-27 and read it very carefully.

By the time you get a used VOR analog indicator, a LOC/GS, and an antenna installed. You’ll be in it for about what some of the new experimental stuff goes for.

Don't quite follow your comment. Are you stating the aircraft previously had Garmin installed, then it was removed, and now you want to reinstall that same equipment?

As to Garmin installations in general, depending on the specific unit, Garmin provides an open Letter of Authorization in the install docs to use their STC. But without more info cant offer a better response.

Typically when we have an A&P install stuff in our aircraft we narrow down what we can use to items that have a STC. Those providers have a AML listing which aircraft the product is straight up approved for. When installed, FAA Form 337 (Major Repair and Alteration) is signed by the A/P and becomes part of the aircraft records.

Problems happen when you have approved parts that aren’t on the AML. There is a ‘field approval’ process that has become unusable.

For example I found a R.C. Allen Mini 6 is a fully FAA-certified TSO digital instrument. I asked AML? They replied TSO! When they really should have said AC23-27
This AC applies to small aircraft type certificated before January 1, 1980, that have a maximum certificated weight of 12,500 pounds or less, fixed wing, un-pressurised, reciprocating engine or sailplanes. Follow-on type certificate (TC) models of the same aircraft, or a derivativethereof, which may be assigned a later TC date, also meet this criteria.

If ALL the criteria can be met an A&P can install the equipment with only a logbook entry.

Having this discussion with my Avionics repair station on the use of a TSO’d STD non AML RC Allen product in a certified aircraft.

He ended up telling the story about installing a product that had beeb an option by the aircraft manufacturer. This aircraft didn’t get this product installed at the factory and the current owner paid him for it to be installed. This would require a 337 & feild approval.

Long story short. The latest batch of FAA types have a ‘prove to me I have to’ mentality and are predisposed to ‘not no, hell no’. And suggested I could either buy another product or pay 5k to a DAR/DER to bypass the unusable field approval process.

I am an A&P. Are you getting a clue why my other aircraft is experimental?

So, if your aircraft is older than 1980, under 12,500, fixed wing, etc. you can install with a log book entry. If not, you have to do a field approval which you say no one will approve.

Am I tracking correctly?

Not quite as you are intermixing various guidance methods. To use you Mini 6 example, a TSO is only a design and production approval and is not an installation approval. So in order to install the Mini 6 the installer must determine if it is a major or minor alteration and proceed accordingly. Full stop.

AC23-27 has zero to do with this as its main applicability is to simply the substitution of parts on older aircraft and does not provide an approval path on new installations which the Mini 6 would be. However, any A&P can substitute any part they choose regardless the aircraft age. The AC merely provides additional guidance to a select group of aircraft.

The “AML” is not a standalone function and is associated with one type of STC, of which there are 4 types: Standard STC, One-Only STC, Non-Interference STC, and the AML-STC. Each has their specific applications. And to add, just because a part falls under an STC doesn’t always mean it is considered a major alteration which requires an 337.

So in the case of the Garmin equipment question, that person has several options. Depending how the previous Garmin equipment was removed and documented it could be as simple as reinstalling the same equipment under the original approval. If, on the other hand, he is referring to a new installation on an aircraft using used Garmin equipment, then depending on the unit model they can follow existing Garmin installation instructions and complete the install. And if that install were to be considered a major alteration, most Garmin documentation on older model lines have the STC LOA included so the installer can legally use the Garmin STC for the approved data.

Like I said. Read ac23-27 very carefully. If you are not 100% sure that you are in full compliance, DON’T!
 
Many of our customers have used BAS in the past with great success - Skyman Avionics is also a decent source. It all depends on the CDI you're looking for.
 
I second BAS up in Greeley for avionics. They have a pretty large selection, and if they don't have the unit in stock, they'll add you to a list when they do receive one. Another place I've had success with is AZ Air Salvage out in Phoenix.

This doesn't touch on the legality of installing avionics in your aircraft, so that's a conversation with your A&P since these units will most likely not come with an 8130.

I have purchased from BAS with good results. I sold all of my equipment to Skyman Avionics when I upgraded my panel. The owner was great to deal with.

I second BAS, and Arizona Air Salvage is another good option. Boxwell Avionics has a store on eBay, but seems to always have a good selection of avionics, and if he doesn't he can sometimes source something for you.
 
When I replaced my DG many years ago, the one I removed had a sticker on the top that said $5. I don't know what flea market the prior owner got that from.
