QUESTIONS & ANSWERS

Question:
What is the Barfield 101-00808 Fuel Quantity Adapter Module used for?
Answer:

The Barfield 101-00808 Fuel Quantity Adapter Module provides the electrical interface between the Dash 8 100, 200, and 300 aircraft and the Barfield DC400A Fuel Quantity Test Set. It allows technicians to perform accurate system tests and calibrations on the aircraft’s fuel probes, wiring, and indicators. This adapter ensures compatibility with the aircraft’s unique capacitance-based fuel measurement system.

Asked October 21, 2025
Question:
Which aircraft models are compatible with the 101-00808 adapter module?
Answer:

The 101-00808 module is specifically designed for De Havilland Dash 8 100, 200, and 300 series aircraft. It is used for testing and calibrating fuel quantity systems on these models, helping maintenance teams verify accurate fuel readings. For Dash-8 400 aircraft, a modified version of this module is used in conjunction with dedicated cables, such as the 101-00874 and 101-00876.

Asked October 21, 2025
Question:
How does the 101-00808 adapter module differ from other Barfield fuel adapter modules?
Answer:

The 101-00808 module is specifically tailored for Dash 8 100, 200, and 300 aircraft and features unique pinouts and interface characteristics that are suited to that platform’s fuel quantity system. Other Barfield modules, such as the 101-00802 or 101-00907, are designed for different aircraft types or engine systems, including Beechcraft and V2500 applications.

Asked October 21, 2025
Question:
Can the Barfield 101-00808 adapter module be used with the Dash 8 Q400?
Answer:

No, not directly. The standard 101-00808 module is designed for Dash 8 100, 200, and 300 series aircraft; however, Barfield offers a modified version for Dash 8 Q400 applications. When testing Dash-8 400 aircraft, this modified module must be paired with the 101-00874 and 101-00876 adapter cables to ensure proper connection and calibration.

Asked October 21, 2025
Question:
What type of testing does the 101-00808 module support?
Answer:

The 101-00808 adapter module supports system integrity, probe calibration, and capacitance testing. It allows the DC400A test set to simulate and measure electrical signals within the aircraft’s fuel quantity circuits, confirming that the system accurately translates capacitance changes into fuel level readings.

Asked October 21, 2025
Question:
Does the Barfield 101-00808 module require calibration?
Answer:

The adapter module itself does not require direct calibration since it acts as a passive interface. However, it should be verified for continuity and insulation resistance as part of the DC400A test set’s annual calibration procedure. This ensures it maintains proper electrical performance and compliance with Barfield specifications.

Asked October 21, 2025
Question:
What are the safety considerations when using the 101-00808 module?
Answer:

Before connecting the adapter, technicians should ensure that the fuel system power is off and all relevant aircraft circuits are grounded. Use in non-hazardous areas only, and always follow De Havilland’s maintenance manual procedures. Handle connectors with care to avoid pin damage and ensure stable connections during testing.

Asked October 21, 2025
Question:
How should the Barfield 101-00808 be stored and maintained?
Answer:

When not in use, the module should be stored in its protective case to prevent dust, moisture, or impact damage. Connector integrity and housing condition should be regularly inspected. Barfield recommends avoiding excessive bending of interface cables to preserve long-term reliability.
