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.

Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 80% of the original exchange price. That is, it cannot cost SEA more than 80% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.

While most TCAS I and TCAS II antennas are manufactured by Sensor Systems for other manufacturers, they all possess different part numbers and models numbers. Some even will indicate a Sensor Systems part number. However, that number indicates proprietary part number and status that Sensor Systems will have with the manufacturers such as Honeywell and L3. You cannot purchase the TCAS antenna with the Sensor Systems part number direct from Sensor Systems.



Regarding interchangeability, there are very similar characteristics between the various TCAS antennas. However, it is not so much the functionality characteristics that determine the interchangeability as it is the certification. That is, since an L3 antenna part number will not be listed in a Honeywell TCAS STC installation manual, you cannot substitute one for the other.
