442369 – Honeywell Main Turbine Engine Fuel Control Unit
Available now on the Airparts.aero Marketplace.
Overview
The 442369 Honeywell Main Fuel Control Unit is a precision-engineered fuel metering system designed for use in turboshaft and turboprop turbine engines. This unit plays a critical role in maintaining engine performance, efficiency, and safety by precisely regulating the fuel flow to the combustion chamber based on a variety of flight and engine conditions including altitude, throttle setting, RPM, and inlet air pressure.
Manufactured by Honeywell Aerospace, a global leader in turbine engine control systems, the 442369 FCU (Fuel Control Unit) integrates hydromechanical actuation with governor, acceleration, and cutoff functions, ensuring reliable operation across starting, idle, cruise, and power-on-demand phases. It is a flight-critical component used in both civil and military applications, and must meet strict standards of airworthiness and operational reliability.
