117-384019-7 – Textron Aviation OEM Fuel Quantity Indicator

Available now on the Airparts.aero Marketplace.

Overview

The Textron Aviation 117-384019-7 is a genuine OEM, flight-critical fuel quantity indicator, engineered for the main fuel tank systems of the Beechcraft Baron 58 series and other high-performance aircraft. This is not a generic gauge; it is a precision-calibrated analog instrument designed to provide the pilot with a clear, continuous, and accurate display of the fuel quantity in the main tanks. As a primary flight instrument, its reliability is paramount for safe fuel management. Manufactured to Textron's exact standards, this indicator ensures a perfect interface with the aircraft's fuel tank sending units and provides the trustworthy readings required for all phases of flight.

Key Features

• Clear Analog Readability: The classic analog dial is designed for instant recognition and interpretation of fuel levels. The gauge face includes clearly marked graduations (e.g., E, 1/4, 1/2, 3/4, F) and is calibrated in U.S. Gallons for the specific fuel tank it measures.
• High-Reliability Meter Movement: Utilizes a robust, shock-resistant D'Arsonval-type meter movement designed to provide accurate and stable readings despite the vibration and dynamic environment of the cockpit.
• Internal Lighting: Equipped with internal lighting provisions to ensure excellent readability during night flight operations, allowing for safe and continuous fuel monitoring.
• Calibrated for Specific System: The indicator's internal resistance and calibration are precisely matched to the variable-resistance signal produced by the fuel quantity sending units in the Beechcraft fuel tanks.
• Genuine Textron OEM Part: As a genuine factory component, it guarantees perfect compatibility with the aircraft's electrical system, correct range markings, and full airworthiness certification as a primary flight instrument.

Applications

The 117-384019-7 is a primary flight instrument with a singular, critical role:

• Fuel Management: Provides the pilot with a continuous indication of the amount of usable fuel remaining, which is the most critical piece of data for flight planning, range calculation, and preventing fuel exhaustion.
• System Troubleshooting: A key component to test and inspect when diagnosing issues with an inaccurate or inoperative fuel quantity indication system.
• Instrument Panel Restoration: The primary component for replacing a failed, inaccurate, or sun-damaged original gauge.

Why Choose 117-384019-7?

Accurate fuel quantity indication is a legal and safety requirement for all flight operations. A faulty gauge can provide dangerously misleading information, leading to a fuel exhaustion scenario. Using a genuine Textron Aviation 117-384019-7 OEM gauge is the only way to ensure that the instrument is properly calibrated for the specific size and shape of your aircraft's fuel tanks and is perfectly matched to the resistance output of the tank senders. For a primary flight instrument this critical, there is no substitute for the certified accuracy and reliability of a genuine OEM part.

The 117-384019-7 indicator operates as part of a ratiometer circuit. The fuel tank contains a sending unit with a float attached to a variable resistor (rheostat). As the fuel level changes, the float moves, which in turn moves a wiper arm across the resistor, changing its electrical resistance. The 117-384019-7 gauge contains a balanced bridge circuit. The changing resistance from the tank sender unbalances this bridge, causing a specific amount of current to flow through the gauge's meter movement. This current deflects the needle against a calibrated spring to a position on the dial that corresponds to the fuel level. The accuracy of the system is entirely dependent on the precise calibration and pairing of the gauge with the specific part number of the engine-mounted senders.

Note: This is a primary flight instrument. Installation and calibration must be performed by a certified A&P mechanic or avionics technician. After installation, the system must be calibrated (typically during a "drip" or "refuel" calibration procedure) to ensure accurate readings at all fuel levels, in accordance with the aircraft maintenance manual.
