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.

The TDR-950 has a plastic bezel assembly which contains the selector switches for ATC code input. This faceplate is held onto the radio assembly by 4 screws. When the faceplate ages, is mishandled or secured too tightly, this plastic bezel can crack. If left cracked and with continued usage, this faceplate can eventually become separated from the transponder thus increasing the possibility of improper transponder performance.
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.
