PWA211430 is a high-performance aerospace engine control printed wiring assembly (PWA), engineered to AS9100D standards and RTCA DO-160G environmental specifications, designed for MRO and integration in Pratt & Whitney PW4000 engines on Boeing 777 and Airbus A330 wide-body aircraft.

Constructed with a rigid FR-4 laminate substrate, gold-plated copper traces, and hermetically sealed connectors, it routes power and control signals between the engine electronic controller (EEC) and critical actuators with <2Ω trace resistance and EMI shielding for signal integrity. The assembly supports 28V DC power and ARINC 429 data protocols, operates at -55°C to 125°C, and weighs 0.65 kg with dimensions of 180mm×120mm×25mm. Compliant with FAA Part 33 and EASA CS-E, it ensures precise engine performance regulation to uphold long-haul fleet efficiency and safety.
