Eaton's Fuel-System Technology Supports 777X Advancements

Date: 6/21/2017

PARIS AIR SHOW, June 2017 — Eaton products have played important roles on the Boeing 777 ever since the first aircraft was delivered more than two decades ago. Since then, Eaton has built on its legacy as a technology leader for the aerospace industry by successfully integrating fuel system components with composite wing aircraft — a key feature of Boeing's new 777X. 

Eaton designed and developed new fuel products that are not only are compatible with composite structures, but also are compliant with FAR 25.981 requirements. Eaton ensures that its equipment meets or exceeds regulatory requirements and customers' expectations.

Eaton's solutions for the 777X significantly expand Eaton's low-risk, high-reliability fuel system content on the aircraft. Eaton has updated and adapted a variety of proven 777 and 787 fuel components for the 777X, including fuel boost pumps, override and jettison pumps, motor-operated shut-off valves and actuators. 

Eaton products on Boeing airplanes help generate, convey and control power and are designed to support fuel, hydraulic, motion, conveyance, ducting, sealing and sensors.
