David Clark 40411G-02 – H10-13H Helicopter Pilot Headset with U-174/U Plug

This helicopter headset ships with a manufacturer’s Certificate of Conformance (CofC), verifying it meets David Clark’s production and quality standards. The CofC is included inside the package at the time of shipment and may be required for maintenance records or aviation audits. If your documentation needs differ, our team can provide additional support when you order.

Yes. The David Clark H10-13H is FAA TSO-certified (C57b and C58a), indicating that it meets stringent performance and reliability standards for aviation communication equipment. It also exceeds RTCA/DO-214 standards for microphone and audio quality. These certifications ensure compliance with regulatory requirements for helicopter operations.

The H10-13H is engineered specifically for the high-noise environment of helicopters. It features a 23 dB certified Noise Reduction Rating (NRR), a lightweight design, and a robust U-174/U single plug, compatible with most helicopter intercom systems. Combined with durability and comfort-focused components, it remains one of the most trusted helicopter headsets in commercial and private aviation.

The headset utilizes the David Clark M-7A amplified electret microphone, renowned for its exceptional noise-canceling performance in high-vibration environments. The microphone features a frequency response of 300 Hz to 3.5 kHz, optimized for clear speech in aviation communications. Its universal flex boom allows precise mic positioning for consistent audio quality.

Yes. The patented David Clark flex/wire boom rotates to either side, allowing for left- or right-side microphone placement. Its detented design provides repeatable positioning, helping pilots achieve consistent mic alignment and voice clarity during radio communication.

The headset uses a U-174/U single plug, the standard connector for most helicopter ICS and radio systems. This makes it compatible with commonly used helicopter audio panels and intercoms, eliminating the need for adapters. Always verify plug type before ordering if your aircraft uses a non-standard interface.

The H10-13H provides a 23 dB passive Noise Reduction Rating (NRR). Its undercut Comfort Gel ear seals and deep ear domes form a strong acoustic seal that reduces rotor noise and low-frequency vibration. This improves audio intelligibility and reduces fatigue during long flights.

The headset features an expanded double-foam head pad and undercut Comfort Gel ear seals, which evenly distribute pressure around the head and ears. These features reduce hotspots and soreness during long-duration flights. The lightweight construction – about 16.5 oz without the cable – also minimizes fatigue.

Yes. David Clark designs the H10-13H with fully replaceable comfort components, including head pads and gel ear seals. Replacement parts such as the Double Foam Head Pad Kit (40688G-36) and Comfort Gel Undercut Ear Seals (40863G-02) are widely available. This extends the headset’s lifespan and maintains consistent comfort over years of use.

David Clark headsets are known for lasting decades when properly cared for. The H10-13H includes a five-year warranty from the manufacturer. Pilots and operators often report far longer service life thanks to its rugged construction, replaceable parts, and Made-in-USA build quality.

The headset utilizes dynamic earphone transducers with a frequency response of 200 to 5,500 Hz, delivering clear communication while prioritizing speech-focused frequencies. Total harmonic distortion stays below 1%, even at high volume levels. This ensures consistent audio clarity in both routine and emergency radio communication.

The molded cord assembly is designed to withstand exceptional pull and flex stress, ensuring long-term resistance to cockpit movement and strain. The extended 5-foot coil cord reduces tangling and provides flexible reach. The U-174/U plug is built to military-grade standards for reliability.

The H10-13H is optimized for helicopters due to its U-174/U plug and passive noise reduction, which is tuned for rotary-wing environments. While technically operable in some fixed-wing aircraft with an adapter, it is not as ideal as standard H10-13.4 communications headsets. Pilots should match the headset plug type to their aircraft’s audio panel for best results.

Yes, but the microphone draws power from the aircraft’s intercom system rather than internal batteries. The M-7A amplified electret microphone operates on 8V to 16V DC and is not polarity sensitive. This ensures stable mic performance without the need for battery replacements.

Absolutely! The H10-13H is widely used in flight training, EMS, utility helicopter operations, and commercial rotor-wing fleets due to its durability and maintainability. Replaceable components, a strong warranty, and proven reliability make it a practical choice for high-use environments.
