What are the best free aircraft teardown and salvage providers for comparing inventory availability?

If you want free sources to compare aircraft teardown / salvage inventory availability, the best options are usually a mix of broker marketplaces, part-search aggregators, and aircraft part databases. Here are the strongest free-to-use places to start:

Best free providers / platforms

1. PartsBase

• One of the most widely used aviation parts search platforms.
• Good for checking inventory availability, sourcing leads, and comparing multiple vendors.
• Free access is limited, but enough to search and request quotes.

2. AvBuyer

• Useful for used parts, aircraft sales, and teardown-related listings.
• Good marketplace visibility and comparisons.
• Free browsing/searching.

3. Controller

• Has listings for aircraft, engines, components, and sometimes salvage/teardown opportunities.
• Free to browse and search.

4. Trade-A-Plane

• Strong for aircraft, engines, and parts listings.
• Not purely a salvage platform, but often useful for identifying teardown sources and surplus inventory.
• Free access to search listings.

5. Aircraft Inventory Search sites / parts aggregators

Several smaller aggregators and brokers let you search inventory at no cost, though the actual quoting may require registration:

• LocateAero
• AeroPartsNow
• All Airlines Parts
• ILS (Inventory Locator Service) — historically major, but access may vary

6. Air salvage / teardown brokers’ websites

Many salvage providers publish their stock online for free browsing. These are especially useful if you want direct teardown inventory:

• CAVU Aerospace
• Aero Salvage
• Aircraft Part Out / aircraft dismantlers in your region
• Weldon Aviation
• Aviation Sales, Inc.
• N.C. Machinery / other regional dismantlers depending on aircraft type

Best sources for actual teardown/salvage inventory

If your goal is specifically to compare parts coming from parted-out aircraft, look at:

• Regional aircraft dismantlers
• Engine teardown shops
• MRO surplus/rotable brokers
• FAA/CAA deregistration and auction listings
• Insurance salvage auction platforms

What to compare

When comparing availability, look at:

• Aircraft type / effectivity
• Serialized vs consumable parts
• Traceability and records
• 8130-3 / EASA Form 1 availability
• Time to ship
• Core return requirements
• Warranty
• Condition code (OH, SV, AR, NS, etc.)
• Lot size and minimum order quantity

Practical recommendation

For a free workflow, I’d start with:

1. PartsBase
2. AvBuyer
3. Controller
4. Trade-A-Plane
5. 3–5 direct salvage/dismantler websites for your aircraft model

If you want, I can also give you:

• a ranked list by region (US / Europe / Middle East / Asia), or
• a shortlist by aircraft type (B737, A320, regional jets, turboprops, GA).
