Operational role and system function

KI 203 is a course-deviation indicator without glideslope presentation. Its OBS resolver and deviation display work with compatible radios and do not receive navigation signals independently. In normal service, correct operation also depends on the associated antennas, sensors, control heads, displays, power, grounding and wiring that belong to the approved aircraft installation. A fault indication at one component does not by itself prove that the component is the source of the system fault.

The equipment must be evaluated as part of its complete signal chain. Controls, connectors or labels visible in a photograph confirm physical features of the photographed configuration, but they do not prove that optional functions, software features or approvals are enabled in a particular aircraft. Approved technical data remains the controlling reference.

Installation and connected equipment

The source lists KN 53 and KX 155 equipment. Installation requires the correct connector, 30 Hz OBS resolver interface, compatible signal wiring, panel mounting and aircraft power or lighting connections. A rack, backplate, connector kit, antenna, coupler, wiring harness or other installation hardware is not assumed to be included unless it is explicitly named in the quotation or Delivery Set.

Before installation, technicians should compare 066-3034-00 with the removed unit, aircraft equipment list, wiring diagram, modification status and applicable manufacturer manual. Panel dimensions, mounting depth, connector keying, pin allocation, circuit protection, lighting, cooling, data format and configuration settings all require confirmation. Similar appearance is not evidence of interchangeability.

Configuration checks for 066-3034-00

The complete designation and suffix are part of the product identity. Hardware revision, modification status, voltage, lighting, software, database, certification and connector configuration can differ between closely related variants. These details should be confirmed against the aircraft records and the specific serial number allocated for supply.

Incoming inspection should verify the manufacturer plate, housing, connectors, locking features, controls, display or indicator face, fasteners and evidence of unauthorized modification. The inspection should also confirm that shipping protection and supplied accessories agree with the quotation. Functional testing should follow the approved bench procedure for the exact model. Installation and return to service remain the responsibility of appropriately authorized personnel.

Serviceable condition, ordering and support

This 066-3034-00 KI 203 is offered in Serviceable condition from Partner Stock with a six-month warranty. Partner availability can change, so allocation, the available serial number, current test status and release documentation are reconfirmed before order acceptance. Image processing does not alter or upgrade the declared commercial condition.

For an inquiry, specify 066-3034-00, model KI 203, quantity, destination and documentation requirements. Adding the aircraft type, removed-unit Part Number and installation details helps prevent configuration errors. Buyers may also request current photographs of the allocated serial number and clarification of the quoted delivery set before confirming the order. Packaging and transport arrangements are selected for the destination and the physical characteristics of the unit.

Related avionics are available in the Garmin / BendixKing / Honeywell / Collins category. Cross-sell products are related catalog positions, not interchangeable replacements unless approved data explicitly confirms substitution.
