No. The Bendix/King KT-73 Level 2 Datalink Transponder uses a different mounting rack and installation kit from the KT-76A. However, the KT-73 does use the same mounting rack as the KT-76C.
No. The KT-73 Level 3 Datalink transponder will only be used for terminal areas not enroute air traffic control. Congested terminal areas poses the greatest challenge for ATC maintaining safe separation and tracking of aircraft.
The KAC-504 traffic module must be installed into the KMD-540 MFD unit (P/N 066-04035-XX0X) to display the traffic information from the KT-73 TIS/Mode S transponder. It should be noted that the Traffic Information Service (TIS) is currently only available in certain areas of the United States.
Many avionics systems require a configuration or setup process. This process is required to interface certain avionics systems to other systems in the aircraft that will be inputting or outputting information to and from these systems. Some examples of systems that require a configuration or setup process include:

Autopilot
EFIS
GPS
EGPWS
EHSI
RADAR
TAWS
TCAS


In addition, most newer technology or solid state systems require configuration via computer interface of some type. A qualified avionics technician should always refer to the appropriate manufacturer's installation manual for complete information and instructions.
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.

For complete information, please refer to these FAA regulations or contact Southeast Aerospace Tech Support team at shop@seaerospace.com.
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.
The KT-73 will fit into most of KT-70/71/76A/76C mounting racks and utilizes the same main connector. However, there are other factors to consider. First, the KT-73 rack includes a configuration module that will store aircraft parameters for the Mode S function. This configuration module is located in the silver box on the right side of the rack (please see photo). In addition, the configuration module has a male connector which can be seen when you peel off the silver tape from the box (see second photo). The designation of this connector is JKT73-4.

All of the TIS (traffic) interface connections for the KMD-550/850 interface are not located on the main connector of the KT-73 (JKT73-1). The TIS ARINC 429 data is output from the KT-73 into the KMD-540 MFD and then output from the KMD-540 into the small config module connector. The small mating connector for JKT73-4 can be purchased separately however it is more cost effective to simply purchase the entire KT-73 installation kit for this scenario.

In conclusion, when upgrading the KT-70/71/76A/76C transponder to the KT-73 with the intention of interfacing to the KMD-550/850 MFD for TIS traffic, you must purchase the correct KT-73 mounting rack and installation kit.
The Mode S aircraft identification code is listed on AC Form 8050-3, Certificate of Aircraft Registration, as the International Civil Aviation Organization (ICAO) Aircraft Address Code. If the aircraft registration does not contain this information, aircraft owners with a Mode S transponder can obtain an aircraft identification code from the FAA Aircraft Registry in Oklahoma City, Oklahoma. This may be accomplished by writing to the following FAA address:

Federal Aviation Administration
Aircraft Registration Branch AFS-750
P.O. Box 25504
Oklahoma City, OK 73125-0504

No, the KT-73 does not meet ADS-B requirements. Previously, the KT-73 could be interfaced to the KMD-540 MFD for display of TIS traffic when operating an aircraft in area with TIS coverage. As of 2013, Bendix/King is working on a replacement for the KT-73 that will comply with the ADS-B mandate.
No, the KT-73 does not and will not meet any ADS-B requirements. There is no upgrade path from the KT-73 other than replacing the KT-73 with an ADS-B capable transponder such as the KT-74 or competing OEM product.
