Industry Leading 90-Day Money-Back Guarantee

You may return parts or request a replacement within 90 days of the purchase date.
No penalties, no re-stocking fees, and no nonsense. Start Here

We do not accept returns on anything marked CORE, on any Fuselage, or on anything stating "No Returns Accepted".

Our 90-day guarantee is our commitment to treating our customers honestly and fairly.
Every part is carefully inspected throughout our process and several times before it goes online. Most items are sold as-removed, just as they came off the aircraft. These parts are not functionally tested. What we do provide is clear photos, full traceability when available, pricing that reflects the as-removed condition, and a no-nonsense 90-day return window.

We do everything we can to get it right, and if something slips through, we stand behind it with a 90-day return policy that’s unmatched in the aircraft parts industry.

If it’s past 90 days, we may decline the return, or we may offer a return with a restocking fee.
We’ll always aim to be fair. Every return gets a human review, not a robot reply.

Once your part makes it back to us, refunds are typically processed within a week, often sooner.
Return shipping is the buyer's responsibility, unless the return is due to our mistake (like receiving the wrong part number).

If you need to return an item or request a replacement, start the process HERE.

Condition Codes for BAS Part Sales Inventory

As-Removed:
Part removed from aircraft in its original, unaltered state. Most of the inventory available from BAS Part Sales is in As-Removed condition. We removed it from the aircraft in working condition and expect it to pass inspection. As-Removed items come with our 90-day Money-Back Guarantee. Read More

Core:
A Core item is a damaged or non-functioning unit that either came to us that way or, during our normal evaluation process, was identified as unsuitable for sale as a standard working item. It is priced accordingly based on its value relative to a working unit. Some may be used for parts, repair attempts, training, display, decor, or other purposes that remain safely on the ground, but they are not expected to work or pass inspection and are unlikely to be suitable for installation on an airworthy aircraft. Core items are listed with "Core" in the title, are not returnable, and are not covered by our 90-Day Money-Back Guarantee.

Overhauled:
An as-removed item that has been sent to a shop for repair or rebuild. These items, of course, come with our 90-day money-back guarantee.

NOS - New Old Stock:
Item that is factory new but has been stored for a period of time that is usually past stock limit date. These items also come with our 90-day money-back guarantee.

Certifications & Documentation:
If an item is offered for sale with an 8130, STC, or other documentation, that detail is typically notated in the product title and the description. If it is not notated, then BAS cannot provide any certification for that item.
