PRODUCT FAQ
Click on a question below to see the answer.
If you have a question about this model that is not answered below,
please contact sales@seaerospace.com

Is the King KT-76A Transponder a direct replacement for the older KT-76 transponder?
No. The KT-76A uses a different mounting rack and installation kit than the KT-76. A rack and connector change is necessary for this upgrade.



  
Is the KT-73 Datalink Transponder a direct replacement for the KT-76A Transponder?
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.



  
What type of faceplate / bezel assembly does the KT-76A have and what is this important?
The KT-76A 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 erroneous transponder performance. Overhauled units from Southeast Aerospace always include either a new faceplate assembly or one without cracks of any type to ensure optimal performance of the transponder.



  
What is the difference between Honeywell (Bendix/King) part numbers with 9 digits vs. 12 digits?
None, they represent the same unit. Original King Radio part numbers were 9 digits. For example, 066-3056-01. During the Bendix and King merger (i.e. Bendix/King), a new part numbering system was created that converted these 9 digit part numbers to 12 digits. Therefore, 066-3056-01 became 066-03056-0001. Despite this numbering change, units that were originally from the King Radio design still have the 9 digit part number format on the unit dataplate. The 12 digit format for King units appears to be used for catalog and internal Honeywell purposes only. Therefore, any unit that has a zero in its third to last number (i.e. XXX-XXXX-X0XX) has a 9 digit part number (i.e. XXX-XXXX-XXX) on its dataplate / ID Plate.



  
Why did Bendix/King change their part numbers from a 9 digit to a 12 digit format?
In January 1989 Bendix/King changed from a nine digit to a twelve digit part numbering system. The new, larger 12 digit numbers allowed for the inclusion of software version into the last two digits of the part number for certain units in which software changed frequently such as EFIS and TCAS processors. Therefore, the two digits immediately preceding the software version indicate the hardware version of the unit.

Different software versions imply different operational features and/or interface capabilities and software modifications imply software repairs (bug fixes) to insure proper operation of these features and interfaces. Software version upgrades frequently require hardware modifications to the unit. Such hardware modifications accompanying software version upgrades do not necessarily change the hardware version of the unit.



  
What is the difference between the Silver Crown and Crown Series version of the KT-76A?
The Silver Crown version has silver trim lining the outside of the faceplate. The Crown Series version has a completely black bezel with no silver trim lining. There is no functional difference between these 2 units. Both utilize the same mounting rack and connector.

Please see the example below of the different versions:




  
What Type of Transponder Do You Need?
Should a new transponder certification be performed if simply replacing an existing transponder?
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.



  
How does Southeast Aerospace calculate exchange prices and acceptable exchange cores?
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 75% of the original SV/OH exchange price billed. Should the Repair Cap exceed 75%, 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 .75 = $750 Maximum Allowable core repair charge or Repair Cap

$2000 Cost to repair core unit
- $750 Less Core repair cap
---------
$1250 Additional billing amount.

2250.00 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.




  
I cannot locate a KT-78A transponder, what can I replace it with?
The KT-78A is simply a low power version of the popular KT-76A transponder. The KT-78A peak power is 113 watts minimum while 200 watts for the KT-76A. The KT-78A was originally designed for low flying aircraft that operated in very local areas such as crop dusting (agriculture) applications. Both the KT-76A and KT-78A are 14 volt radios that utilize the same mounting rack and connector. Therefore, the higher power KT-76A is an ideal direct replacement for the KT-78A considering that the KT-78A has not been manufactured for many years and is therefore scarce on the used market.



  
Are SEA's Exchange prices negotiable?
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 75% of the original exchange price. That is, it cannot cost SEA more than 75% 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.

I need a basic transponder antenna, which one should I buy?
Although some manufacturers call out specific transponder antennas in their installation manuals, almost any transponder antenna can be used with any transponder. Various models are available based on the screw hole pattern desired and the speed & drag considerations based on the aircraft type.

AV-22 CI-101

For smaller general aviation aircraft, Southeast Aerospace recommends the stub type AV-22 or CI-101 antenna.


CI-105 AV-74

For medium to larger aircraft, Southeast Aerospace recommends the blade type CI-105 or AV-74 antenna.


Ultimately, it is the responsibility of the installer or installing agency to determine what antenna is suitable for the aircraft application.



  
What is the difference between the racks for the KT-76A and KT-76C transponders?
The original KT-76A mounting rack Part Number is 047-03898-0002. The rack included with a new KT-76C is Part Number 047-09628-0004. Either unit will fit into either rack. Also, as a direct, slide-in replacement for the KT-76A, the KT-76C utilizes the same connector in the same rack position as the KT-76A.

Rack P/N 047-09628-0004 was also used with the KT-70 and KT-71 transponders. Therefore, the 047-09628-0004 rack included additional features such as a port for cooling fan connection and space for a configuration module.
