Frequently asked
Does the Audio Controllr/Single Channel AMS43 TSO include certification paperwork?
This item is supplied as "Condition disclosed" rather than with full 8130-3 traceability — normal for some condition codes, and it does not mean the part is unusable, only that the paperwork profile differs. Check the listing for exactly what documentation is included, and request any available records before you purchase if your installation requires them.
What condition is this part?
This part is listed in condition as listed — Condition disclosed. Condition codes describe how a part reached its current state (for example new, overhauled, serviceable, repaired, or as-removed) and directly affect what paperwork ships with it and how it should be installed. See the Glossary for the full definition of every condition code we use.
How fast does it ship?
This item is in stock and ships promptly, usually the same or next business day once your order and payment are confirmed. Exact transit time depends on your shipping method and destination and is shown at checkout. If your aircraft is grounded, AOG expedited handling is available on request — no phone tree required.
Can I return it?
You may return this item within 30 days of delivery if it is unopened, uninstalled, and in its original packaging. Items that have been installed, powered on, opened hazmat, or separated from an attached 8130-3 tag are non-returnable because their airworthiness status can no longer be confirmed once removed from the part. See our Returns policy for the full process.
