David Clark 41035G-05 Pushback Interface Cord with U-174/U Plug & In-Line Impedance Adapter

The 41035G-05 Pushback Interface Cord is designed to connect the David Clark U9920-GPB Pushback Gateway to a low-impedance military aircraft communication system. It serves as the physical link between wireless ground crew headsets and the aircraft intercom, enabling clear communication during pushback, towing, and maintenance operations.

This interface cord is used exclusively with the David Clark U9920-GPB Pushback Gateway (40993G-01). One end of the cord connects to the gateway, while the other end connects to the aircraft input port via a U-174/U plug, which is a standard connection on many military aircraft communication systems.

No. The 41035G-05 is designed for military use only and is built to match the low-impedance requirements of military aircraft intercoms. For civilian or general aviation applications, other David Clark interface cords, such as the 41035G-03 or 41035G-04, are recommended.

The 41035G-05 features a U-174/U plug on the aircraft side and a quick-connect fitting on the gateway side, ensuring secure connections and easy setup. It also incorporates an in-line impedance adapter, which allows proper signal matching between the U9920-GPB Gateway and military aircraft audio systems.

The in-line impedance adapter ensures that the communication signals between the gateway and the aircraft intercom are balanced and clear. Without impedance matching, users could experience distorted or weak audio transmission. The adapter stabilizes the signal for optimal two-way voice performance during push-back operations.

Installation is straightforward: one end connects to the U9920-GPB Pushback Gateway, and the other end plugs into the aircraft’s communication input port. If the aircraft’s port contains a built-in push-to-talk (PTT) switch, a special cable may be required to bypass it for continuous communication flow.

During pushback, the 41035G-05 acts as the hardline link between the aircraft interphone and the wireless David Clark 9900 Series communication system. It allows ground crews using wireless belt stations to communicate directly with the cockpit crew through the U9920-GPB Gateway, maintaining constant, hands-free coordination for safe aircraft movement.

Yes. When used with the U9920-GPB Gateway, the system supports up to four connected wireless belt stations, allowing multiple team members to communicate with the cockpit simultaneously. This enhances coordination and efficiency during pushback and towing operations.

Before connecting, ensure both the gateway and aircraft intercom are powered down to avoid electrical interference or static discharge. Inspect connectors for damage and verify that all contacts are clean. If the aircraft has a PTT circuit, confirm whether a bypass adapter is required to maintain full-duplex communication.

The 41035G-05 is built to military-grade standards, with a reinforced cable jacket and strain-relief features to withstand heavy use in ramp and flight-line environments. The connectors are engineered for repeated connections and disconnections under extreme temperatures and vibration conditions typical of ground support operations.

Regularly inspect the cord and connectors for signs of wear or contamination. Clean the cable exterior with a mild soap-and-water solution, avoiding solvents that may damage the insulation. Store the cord neatly coiled in a dry environment to prevent stress on connectors and prolong its service life.

If damage occurs, repairs should be handled only by authorized David Clark service personnel to ensure maintenance of performance and safety standards. Contact David Clark’s Customer Service department for support or replacement parts rather than attempting self-repair, as improper modification could affect system performance.

The 41035G-05 Pushback Interface Cord provides rugged reliability, precise impedance matching, and dependable signal clarity, making it ideal for demanding military ground environments. Its seamless integration with the U9920-GPB Gateway ensures uninterrupted communication between flight crews and ground personnel – critical for safe and efficient aircraft handling.
