T53 – Start Fuel Solenoid Valve

Identification and Location

The emergency solenoid valve is mounted on the Fuel Control Unit.

System Design

It is a two position valve, which when positioned to automatic, directs fuel flow to the (automatic) metering valve. When the valve is positioned to emergency, it directs fuel to the emergency (manual) metering valve. After installing an Engine or Fuel Control Unit, during airframe intermediate inspections, or when a special verification of the proper operation of the AUTOMATIC/EMERGENCY system is required, perform an operational test of the system.
