Test on a B737 Fuel Control Valve

International Aircraft Technician Saemi Talks About How He Uses the Mag-Probe on Aircraft. Saemi sent the following Email regarding his Test on a Boeing737 Fuel Control Valve and how quickly he solved the problem using the Bartol Mag-Probe.

Hi Bob,

Just yesterday we had a mechanical failure with a B737 fuel control valve. My collages were running around with a Fluke Meter. It only took me a few minutes to isolate the failed Fuel Valve with a Mag-Probe.

FUEL CONTROL VALVE

The Valve also supplies fuel to the APU engine 0n a B737 is critical to the safe operation of the emergency electrical back up Power System of the aircraft which can also cause delayed flights because this system must be operational before the plane is cleared for take off. Wikipedia The primary purpose of an B737 aircraft APU is to provide power to start the main engines. Turbine engines must be accelerated to a high rotational speed in order to provide sufficient air compression for self-sustaining operation. Smaller jet engines are usually started by an electric motor, while larger engines are usually started by an air turbine motor. Before the Boeing B737 engines are to be turned, the APU is started, generally by a battery or hydraulic accumulator. Once the APU is running, it provides power (electric, pneumatic, or hydraulic, depending on the design) to start the aircraft’s main engines. Read more……
