BendixKing KR 87 receiver 066-1072-14

066-1072-14 is the exact short-form Part Number for this BendixKing KR 87 automatic direction finder receiver. The photographed configuration also carries the zero-padded manufacturer form 066-01072-0014. The panel-mounted receiver gives the crew frequency selection, mode control, timer functions and an interface to compatible ADF bearing equipment. It requires approved antenna, indicator, audio, power and aircraft wiring to form a working installation.

The -14 suffix distinguishes this unit from the 066-1072-04 KR 87 and other family configurations. Similar front panels do not prove identical lighting, supply, connector wiring, modification status or approval. Replacement should be based on the complete plate, installed-equipment records and approved wiring data. No characteristic from the -04 version is used as evidence for the -14 unit unless independently common to the model.

Frequency selection and ADF operation

The KR 87 receives signals from selected nondirectional radio beacons and provides processed information for a compatible bearing indicator. Its display supports active and standby frequency management, while the transfer control changes the selected frequency according to the operating procedure. The resulting bearing is influenced by antenna installation, signal propagation, station geometry, terrain, weather and electrical interference and must be interpreted within approved navigation procedures.

ADF mode supports normal bearing operation. BFO is available for suitable identification signals. FLT/ET and SET/RST controls manage flight-time or elapsed-time functions presented by the receiver. These timer features are separate from the radio bearing function. Functional testing should therefore confirm both navigation-related behavior and the front-panel display and timer controls.

Companion equipment and signal flow

A representative chain is crew selection at the KR 87 → receiver frequency generation and processing → compatible loop and sense antenna → NDB transmission → bearing output → approved cockpit ADF indicator. Station identification audio can be routed through the aircraft audio system. The exact bearing-indicator and antenna Part Numbers must be taken from the aircraft documentation, because several similar King-family components exist.

Fault isolation should include the antenna and its cable, power, connector, audio path, bearing indicator, aircraft bonding and the external station environment. A front display that powers normally does not by itself confirm valid bearing performance. Related products offered in the same avionics category are system-associated inventory and are not represented as interchangeable with 066-1072-14.

Identification and configuration control

The gallery identification view documents Part Number 066-1072-14 together with the expanded 066-01072-0014 form, serial number 78340, KR 87 ADF Receiver marking, TSO C41c and DO-160 references. A separate configuration reference 066-01072-0099 is also visible on the photographed unit. These markings should be preserved in the receiving record and compared with the release documentation.

Exact dimensions, weight, supply, current consumption, lighting and pin assignment have not been guessed from another KR 87 version. Before installation, verify those parameters in the approved manual for the complete configuration. Receiving inspection should check the bezel, display, keys, knobs, tray surfaces, rear connector, cooling condition, plate, modification markings and overhaul release. Testing should cover tuning, transfer, ADF, BFO, timer, dimming, audio and valid bearing output.

Overhauled supply and ordering information

This 066-1072-14 KR 87 is offered in Overhauled condition from partner stock with a six-month warranty. The quotation will confirm the allocated serial number, overhaul organization, release certificate, test status and supplied accessories. Tray, connector, antenna, bearing indicator, audio equipment and installation hardware are included only when expressly identified.

For an inquiry, specify both 066-1072-14 and 066-01072-0014, model KR 87, aircraft type, antenna and bearing-indicator configuration, supply and lighting requirements, modification status, quantity and required certification. Related navigation products are available in the Garmin / BendixKing / Honeywell / Collins category. Authorized maintenance personnel must establish final eligibility and interchangeability from approved aircraft data.

Retaining both Part Number formats in the inquiry helps prevent a model-only match and gives the supplier a clear basis for checking the exact inventory plate.
