In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

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.
Yes, anytime a transponder is removed or replaced an altitude correlation between what the transponder is reporting and what is displayed on the altimeter needs to be performed. This is outlined in FAA CFR Part 91.413. This regulation indicates that following any installation or maintenance of a transponder where data correspondence error could be introduced, the integrated system has been tested, inspected, and found to comply with paragraph (c), appendix E. Furthermore, these references indicate that an integration test between the altitude reporting equipment and transponder system must be conducted.

Most of the King (now Honeywell) Gold Crown components were originally manufactured in the early to mid 1970s. King then Bendix/King now Honeywell discontinued production these components many years ago replacing them with the Bendix/King Gold Crown III product line.

Most of the original Gold Crown products incorporate 1960s and 70s analog technology. As a result, most service parts needed to maintain and repair original King Gold Crown components are no longer available. Therefore, you will experience limited to no warranty available and unreliability for all of the original Gold Crown units.

Southeast Aerospace offers many affordable, upgradeable options for aircraft with original Gold Crown avionics. As avionics integration specialists and premier Honeywell Bendix/King dealer, Southeast Aerospace is experienced and knowledgeable on all Gold Crown generations.

If you are interested in upgrading any of your original Collins Gold Crown systems, then please contact us for the most reasonable, optimal choice available.
