100-380006-167 - Textron Aviation OEM Fuel Quantity Probe

100-380006-167 – Textron Aviation OEM Fuel Quantity Probe

Available now on the Airparts.aero Marketplace.

Overview

The Textron Aviation 100-380006-167 is a genuine OEM, flight-critical fuel quantity probe, an advanced sensing unit engineered for the fuel tank systems of the Beechcraft King Air 200 series. This is not a simple float sensor; it is a sophisticated capacitance-type fuel probe designed to provide extremely accurate and reliable fuel quantity measurements. Its function is to convert the level of fuel in the tank into a precise electrical signal, which is then processed and displayed on the cockpit's fuel quantity indicators. As a genuine Textron OEM part, it guarantees the correct calibration and performance required for safe and accurate fuel management in a transport-category aircraft.

Key Features

• Capacitance Measurement Technology: Utilizes the principle of electrical capacitance to measure fuel quantity. This solid-state design has no moving parts (like floats or wipers) to wear out or fail, providing exceptional reliability and accuracy.
• High-Accuracy Readings: Capacitance probes are significantly more accurate than older float-type rheostats, especially in changing aircraft attitudes. They provide stable, repeatable readings that accurately reflect the true fuel volume in the tank.
  
• Durable Construction: Built with concentric metal tubes (plates) housed within a rigid, fuel-impermeable structure. The entire assembly is designed to withstand constant immersion in Jet A and resist the vibrations and G-forces of flight.
• System Integration: Engineered to integrate seamlessly with the King Air's fuel quantity signal conditioner and cockpit indicators, providing the correctly calibrated signal required by the system.
• Genuine Textron OEM Part: As a genuine factory component, it guarantees conformance to the strict material, electronic, and performance specifications required by the original aircraft Type Certificate.

Applications

The 100-380006-167 is a flight-critical sensor essential for safe fuel management:

• Primary Fuel Quantity Indication: The in-tank sensor that provides the raw data for the primary fuel quantity displayed to the flight crew.
• Fuel System Troubleshooting: A key component to test when diagnosing inaccurate, fluctuating, or inoperative fuel gauge readings.
• Component Replacement: Replaced when the probe fails its periodic capacitance checks or is found to be physically damaged or leaking.

Why Choose 100-380006-167?

Accurate fuel quantity indication is one of the most critical safety-of-flight parameters. A faulty probe can provide dangerously misleading information, leading to a fuel exhaustion scenario. Using a genuine Textron Aviation 100-380006-167 OEM probe is the only way to ensure the component has the correct length, calibration, and capacitance range to function accurately with your aircraft's specific fuel tank shape and indication system. For a system this critical, there is no substitute for the certified accuracy and reliability of a genuine OEM part.

The 100-380006-167 capacitance probe functions as a variable capacitor. It consists of two concentric, electrically isolated tubes that are immersed in the fuel tank. The fuel itself acts as the dielectric material between the tubes. The probe's capacitance is a direct function of the dielectric constant of the material between the plates and the area of the plates covered by that material. Air has a dielectric constant of approximately 1, while jet fuel has a dielectric constant of approximately 2. As the fuel level in the tank decreases, more of the probe is surrounded by air, and the overall capacitance of the probe decreases in a precise, linear fashion. A signal conditioner measures this change in capacitance and translates it into the fuel quantity reading displayed in the cockpit.

Note: This is a flight-critical fuel system component. Installation, calibration, and testing must be performed by a certified A&P mechanic or avionics technician in strict accordance with the current Textron Aviation (Beechcraft) maintenance manual. Proper sealing of the probe to the fuel tank is essential to prevent leaks.
