KTU 709 TACAN receiver with tune-source selection 066-1074-02

066-1074-02 is the exact Part Number for this BendixKing / Honeywell KTU 709 TACAN receiver with tune-source selection. The unit receives compatible TACAN signals and supports bearing and distance presentation through approved connected avionics. This card is tied to the photographed configuration and complete suffix, rather than serving as a generic listing for every KTU 709 version or a visually similar member of the same family.

The source record identifies Part Number 066-1074-02 as an overhauled KTU 709 supplied with EASA Form 1. The photographed unit carries the exact Part Number and serial number 2904. TSO status is stated in the source listing. Detailed electrical and environmental values were not independently confirmed in reliable open documentation for this exact suffix. The identification information is important because voltage, lighting, software, hardware options, certification and connector configuration can differ across related versions. The complete Part Number and the approved technical record must be checked together before purchase or installation.

Operational role and system function

The source listing describes the KTU 709 as a TACAN receiver with tune-source selection and frequency agility. It may be used with a KDI 572 or KDI 574 indicator, or controlled through a compatible KFS 579A installation. The photographed rear panel shows the receiver housing, connection points and exact KTU 709 identification rather than a self-contained cockpit display. In service, the unit depends on the integrity of its associated sensors, antennas, transceivers, control panels, displays, data buses, wiring, power and grounding. A reported fault at the unit can therefore originate elsewhere in the connected chain, and troubleshooting should follow the approved aircraft and equipment procedures.

The practical role of KTU 709 is to perform its defined function while exchanging required signals with compatible equipment. It cannot replace missing system components and should not be evaluated as an isolated consumer device. Controls or connectors visible in photographs do not prove that every possible function is enabled in a particular aircraft installation.

Installation and connected equipment

The approved TACAN installation can include a KDI 572 or KDI 574 indicator, or a compatible KFS 579A control, together with the applicable antenna, coaxial cable, aircraft power, rack, connectors, wiring and indication circuits. The exact control source and interface configuration must be confirmed from the aircraft equipment list and approved BendixKing data. A rack, backplate, connector kit, antenna, wiring, cooling hardware or other accessories are not assumed to be included unless they are expressly listed in the quotation. Similar panel dimensions or family names do not prove electrical or approval compatibility.

Before installation, technicians should compare 066-1074-02 with the removed unit, aircraft equipment list, wiring diagrams, installation manual and modification records. Panel space, mounting depth, connector keying, pin allocation, circuit protection, lighting, ventilation, data format and configuration settings all require confirmation. Any substitution must be supported by approved data.

Configuration checks for 066-1074-02

The suffix in 066-1074-02 is part of the product identity. Software level, modification status, database requirements, embedded options, voltage and certification can affect compatibility even when two units look alike. These checks are especially important in aircraft that have accumulated supplemental approvals, avionics upgrades or wiring changes over time.

Incoming inspection should verify the manufacturer plate, housing, connectors, locking features, controls, display or indicator face, fasteners and evidence of unauthorized modification. Functional testing should use the approved bench procedure for the exact model and suffix. Installation and return to service remain the responsibility of appropriately authorized personnel.

Overhauled condition, ordering and support

This 066-1074-02 KTU 709 is offered in Overhauled condition from partner stock with a six-month warranty. Partner stock should be reconfirmed at quotation because allocation can change. The available serial number, current test status and release documentation for the specific unit are confirmed before order acceptance.

For an inquiry, specify Part Number 066-1074-02, model KTU 709, required quantity, destination and documentation requirements. Including the aircraft type and removed-unit Part Number helps prevent configuration errors. Related avionics can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Products shown there are related catalog positions, not interchangeable replacements unless approved technical data explicitly says so.
