As part of our promise to provide the most honest, quality service to our customers, Southeast Aerospace adheres to strict guidelines for certification according to the FAA and Original Equipment Manufacturers (OEM). While most avionics components do not include a prescribed overhaul procedure in the Maintenance Manual, the FAA has set forth guidelines for the cleaning and inspecting of components as referenced in FAR Part 43.2. Therefore, if a component cannot meet the standards of this Federal Air Regulation in relation to inspection criteria and cleaning potential then it should not be deemed as Overhauled. Southeast Aerospace does not believe in simply providing words on a tag or maintenance release to represent the condition of a component. SEA stands behind the work and service followed through with each and every FAA 8130-3 maintenance release it provides.
Until the used market completely dries up, you can still find someone who will sell you a KMA-20. The KMA-20 may have been a cost effective, reliable unit at one time but unfortunately its time has passed. Most older avionics units have become increasingly challenging to repair as the manufacturers discontinue support and cut off the supply of service parts. Likewise, even if you can find a KMA-20 in working condition, it usually has little or no warranty. Instead of continuing to invest your money in obsolete technology and delaying the inevitable, Southeast Aerospace suggests upgrading to the KMA-24. Investing in the KMA-24 will provide you with an audio panel that includes warranty and support for many years to come.
