Aircraft Avionics For Sale

Aircraft Avionics from a Large, Active Inventory

BAS maintains a broad inventory of aircraft avionics sourced directly from ongoing aircraft disassembly, with new components being added regularly as inventory continues to move.

Avionics Overview

Built for Constant Inventory Movement

As BAS continues to expand its aircraft disassembly and parts inventory, avionics remains one of the most active categories on the BAS Part Sales website. While our avionics inventory is deep, it is also in constant motion. New components are added regularly as aircraft move through disassembly, while parts continue to sell throughout the day across a wide range of platforms and applications.

Our aircraft avionics inventory supports everything from light sport and piston aircraft to turbine aircraft and high-performance platforms, including Citation, Hawker, King Air, and TBM aircraft. At any given time, BAS lists more than 10,000 indicators for sale online, along with transponders, GPS and navigation equipment, audio systems, antennas, flight displays, instrument panels, and other essential panel components sourced directly from aircraft we acquire and disassemble.

How BAS Operates

Structured for speed, visibility, and straightforward buying

In StockIf it is listed on the BAS website, it is already on hand and available to purchase.
97% Same Business Day ShippingMost orders leave the same business day, including many larger items.
Published PricingEvery item has a listed price, including core exchange items.
The BAS Advantage

How BAS Makes Avionics Sourcing Easier

No Lead Time Chase

BAS does not use listed inventory as a placeholder. If an avionics item appears on the store, it is in stock, available to purchase, and ready to ship without manual availability checks.

Published Pricing

Every item on the BAS store carries a published price, including core exchange items. Customers can move forward without waiting on a quote or dealing with call-for-price friction.

Detailed Listings

Each avionics listing includes multiple high resolution images so customers can review markings, wear, dings, and visible condition details before placing an order.

90-Day Guarantee

Items not marked Core or No Returns are backed by a 90-day money-back guarantee, giving buyers a more straightforward return window than is typical in the used aircraft parts market.

Order Online, No Call Required

Most items can be purchased directly through the BAS website without needing to call, wait for a quote, or work through manual order handling. If you are ready to buy, place the order online and we will get it on the way.

Worldwide Shipping

Most items can be purchased directly through checkout and shipped worldwide without requiring a separate quote.

Availability and Purchasing

Airplane Avionics for Sale Online with Clear Details

Because some avionics move quickly, not every part stays available for long. Certain units are purchased almost immediately and may not remain on the website for extended periods. If you do not see the avionics component you need listed online, contacting BAS directly is a smart next step. Inventory changes continuously, and there are times when incoming parts, recently processed components, or fast-moving items may not be reflected in the exact moment you search.

BAS structures avionics sourcing to reduce the friction that often slows used aircraft parts buying. Most items can be purchased directly through online checkout and shipped to a wide range of domestic and international destinations, allowing customers to move from search to purchase without unnecessary back and forth.

Product pages are documented as clearly as possible before sale. Customers can review multiple high resolution images on every listing, often with enough detail to zoom in on wear, markings, dings, and other visible condition details. That level of documentation supports faster decision making and reduces uncertainty when sourcing used avionics components online.

All avionics are sold as-removed, meaning they are offered exactly as they came out of the aircraft during disassembly, with basic traceability maintained through the BAS process. BAS does not represent these parts as inspected, overhauled, or newly tagged beyond basic traceability. Items not marked Core or No Returns are backed by a 90-day money-back guarantee.

Frequently Asked Questions

Common Questions About BAS Avionics

Are BAS avionics actually in stock?

Yes. Every item listed on the BAS website is in stock and on hand. If it is on the store, it is available to purchase and ready to ship.

How quickly do orders ship?

Most orders ship the same business day. Across the operation, about 97% of orders ship the same business day, including many larger items.

Do you publish pricing on every item?

Yes. Every item has a published price, including core exchange items. There are no call for price listings on the BAS store.

What if I do not see the avionics I need listed?

Because inventory changes continuously, some parts may sell quickly or be in process before they appear online. If you do not see the component you need, contacting BAS directly is recommended.

Are BAS avionics inspected or overhauled before sale?

No. BAS sells avionics and other parts as-removed, exactly as they came out of the aircraft during disassembly, with basic traceability maintained through the listing process.
