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.
Weather radar transceivers use a magnetron which is basically a cathode emission device. The magnetron is subject to deteriorization due to aging. Therefore, it is recommended to perform some type of periodic maintenance to detect and correct the effects of aging. This reduces the chance of an in-service failure.

An annual, routine test of the following parameters should made:

- Power output
- Transmitter frequency
- AFC voltage
- Sensitivity (MDS)

Ideally, the test should take place between December and March prior to the peak thunderstorm season.
Southeast Aerospace exchanges are based on the return of an undamaged, economically repairable core unit with identical part number as the unit shipped to the customer. An "economically repairable" core is defined as one where the cost to repair/overhaul (or Repair Cap) does not exceed 80% of the original SV/OH exchange price billed. Should the Repair Cap exceed 80%, the customer will be billed the additional amount. In the event this amount exceeds the Outright Price for the unit, the customer would only be billed the difference between the Outright Price and SV/OH Exchange Price with the core returned as-is to the customer.

Here is an example of such a transaction:

$1000 Exchange Price charged to customer
$1000 x .8 = $800 Maximum Allowable core repair charge or Repair Cap

$2000 Cost to repair core unit
- $800 Less Core repair cap
$1200 Additional billing amount.

2200.00 Total Cost of transaction

Please Note:
SEA offers exchange on new items as well. However, repair cap as indicated above is still based on SV/OH exchange price.
