856A3760G04 is a mission-critical aerospace flight control interface module, built to AS9100D quality benchmarks and RTCA DO-160G environmental standards, optimized for narrow-body aircraft like the Boeing 737 MAX and Airbus A320neo to support in-service operations and MRO tasks.

Housed in an EMI-shielded aluminum alloy enclosure with an IP68 hermetic seal, it acts as a communication bridge between the flight control computer (FCC) and secondary control surfaces (flaps, slats, spoilers), delivering <4ms data latency and 99.999% signal integrity. It features dual redundant data channels for fault tolerance, integrated signal conditioning, and wide-temperature compensation (-55°C to 125°C). Running on 28V DC power, it weighs 0.92 kg and measures 122mm×85mm×52mm. Compliant with FAA Part 25/EASA CS-25, it ensures precise, responsive flight control and elevates overall aircraft operational safety.
