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.
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.

Yes, due to the delicate construction of these instruments, Southeast Aerospace follows the Honeywell Service Memo #377 in relation to specifications for transportation and handling of the KI-256 Flight Indicator and KG-258 Gyro.
Please see the Honeywell Service Memo for detailed information.

No. At one time, Bendix/King offered the KI-254 (P/N 060-0037-XX) as an electric alternative for the air driven KI-256 flight director indicator. The KI-254 was a 28 VDC unit only. The KI-254 was manufacture red by Castleberry instruments for Bendix/King. Castleberry no longer manufactures the KI-254 nor offers an alternative. It should be noted also that none of the KFC-150 or KFC-200 STC installation manuals include the KI-254 flight director indicator.
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 KI-256 is a gyro based attitude indicator that is an integral part of the KFC-200 flight control system. The KFC-200 autopilot is installed per STC. Therefore, it cannot be easily removed and replaced with another instrument.

Recently, Garmin has developed the G600 flight deck retrofit that integrates with existing KFC-200 systems. This is a system that integrates many flight display and navigation features not simply attitude and flight control information. The dual screen G600 integrates with other Garmin avionics systems such as the GNS430/530 providing both Primary Flight Display (PFD) and Multi-Function Display (MFD) functions. Furthermore, the Garmin GAD-43 adapter eliminates the system's need for gyro instruments such as the KI-256. The GAD-43 provides AHRS attitude/heading reference.

Therefore, there is not a plug-and-play, direct replacement solution for the KI-256 instrument only.

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.

At Southeast Aerospace, an overhaul of a KI-256 involves a complete teardown of the unit replacing all bearings and worn or defective parts. To maximize the service life of the rotor bearings after they are replaced, the rotor is initially balanced to within tolerance. They are then run-in for a minimum of 52 hours while rebalancing the rotor during and after the run-in period. All work is also performed at Southeast Aerospace in our ISO class 8 certified clean room to prevent contamination during buildup and alignment of the instrument. Upon completion of alignment to factory specs and required test procedures, the KI-256 is then run on the Scorsby table for a minimum of two more hours for quality assurance.
