QUESTIONS & ANSWERS
The David Clark C31-26 Coiled Extension Cord extends the communication range between a David Clark Series 3000 Ground Support Headset and the aircraft or intercom connection point. It’s designed to provide ramp and maintenance crews with extra mobility while maintaining clear and reliable communication. This 26-foot cord helps prevent strain on headset cables during active ramp operations.
The C31-26 extension cord is specifically designed for use with David Clark Series 3000 noise-attenuating headsets, including models like the H3313 and H3331. It connects directly to the headset’s SC-838 jack and the aircraft’s PJ-051 plug or ground support intercom, ensuring a secure and interference-free connection during ramp or maintenance operations.
The cord features a female SC-838 connector on one end and a male PJ-051 or 1/4" TRS plug on the other end, depending on the system configuration. This setup allows it to integrate seamlessly with most standard aviation ground support communication systems. The connectors are built to withstand frequent connections and disconnections without compromising signal integrity.
The C31-26 extends to approximately 26 feet (7.9 meters), providing ample flexibility for ramp or maintenance crew movement. Its coiled design prevents tangling while allowing the cord to stretch as needed and retract neatly when not in use. This balance of flexibility and organization keeps work areas safer and more efficient.
Yes. The C31-26 can be paired with other David Clark extension cords or headset accessories to customize communication setups for specific ground support environments. It’s part of the C31-XX Series, which includes multiple cord lengths and connector configurations to fit different operational needs.
Absolutely! The C31-26 is purpose-built for ramp, hangar, and maintenance communication where clear, noise-free coordination is critical. Its durable coiled construction resists abrasion and wear from high-traffic environments, making it the standard choice among airlines, MRO facilities, and ground support teams worldwide.
Like all David Clark products, the C31-26 is engineered for exceptional durability. Its heavy-duty insulation and reinforced strain reliefs protect against wear, oil, fuel, and extreme temperatures. The coiled design also helps prevent kinks and damage caused by dragging or excessive stretching, ensuring years of dependable service.
Yes. The C31-26 is constructed with aviation-grade materials that resist damage from exposure to moisture, hydraulic fluids, and aviation fuel. This makes it well-suited for outdoor use on busy ramps and in hangars where environmental conditions can be unpredictable.
After each use, allow the cord to retract naturally to prevent overstretching or twisting. Wipe the outer jacket with a clean, dry cloth to remove dust or fuel residue. Avoid sharp bends that could strain the internal wiring. Store the cord in a cool, dry place – ideally on a cord reel or in a protective case – to prolong its service life.
Yes, the C31-26 extension cord can be serviced or repaired through authorized David Clark repair centers. Replacement parts for connectors or damaged sections are available; however, professional servicing is recommended to maintain optimal performance and ensure safety standards are met.
The C31-26 is primarily designed for ground support and maintenance communication systems, but it can also interface with certain aircraft intercom jacks using standard 1/4" TRS or PJ-051 connections. Always confirm compatibility with your specific aircraft or intercom setup before use to ensure proper communication function.
Airlines and MRO operators trust the David Clark C31-26 because it combines long reach, coiled flexibility, and rugged reliability in one package. Its proven performance, easy compatibility with Series 3000 headsets, and ability to withstand daily use make it a staple in professional ground support communication setups worldwide.
