The potentiometer identified by part number 6005-2007-130 is used on the Hawker 800 series, including the 800XP, 850XP, and 900XP, as a flight control position sensor. It functions as the aileron surface position transmitter for the autopilot system, providing real time feedback to both the autopilot and the flight data recorder.

System Function and Operation Role

Installed in the left wing dry bay area, this potentiometer connects to the aileron control linkage and detects actual surface deflection. Its output is essential for two systems:

• Autopilot feedback loop:
Allows the autopilot to compare commanded input with true aileron position.
• Indicating and recording systems:
Feeds positional data to flight instruments and recording units.

This sensor plays a key role in maintaining both autopilot accuracy and overall system integrity. A failed or out-of-rig potentiometer may lead to autopilot disconnects or inaccurate display data, making its calibration and condition directly linked to flight system performance.

Part Number and Variants

• Primary Part Number: 6005-2007-130
• Legacy Part Number: M2078-4-502

Maintenance records and IPC references indicate that part number 6005-2007-130 is consistently used across the Hawker 800XP series as the potentiometer serving the aileron position sensing function. In earlier documentation and vendor catalogs, this same component may appear under the legacy designation M2078-4-502, used in similar control feedback roles. This suggests a standardized potentiometer design across multiple flight control axes

Replacement and Maintenance

The potentiometer is a line-replaceable unit (LRU). It can be accessed through an external wing panel and removed without major disassembly. Replacement involves disconnecting its linkage and electrical harness, followed by sensor calibration.

There is no set overhaul interval: the component is serviced on condition, typically replaced if it fails calibration or exhibits an unstable signal. Precision rigging is required during installation, with alignment marks and voltage tolerance checks specified in the aircraft’s maintenance manual.

Supported Hawker Compatibility

This potentiometer configuration applies to:

  • Hawker 750
  • Hawker 800XP
  • Hawker 850XP
  • Hawker 900XP

While connector or harness details may vary slightly by aircraft serial number, the potentiometer’s function and installation method remain consistent across these aircraft.

Overview

The 6005-2007-130 potentiometer serves as a critical feedback sensor for the aileron system on Hawker 800 series aircraft. It supports autopilot stability and position recording and is directly replaceable per OEM maintenance procedures. For operators sourcing this component, confirming model compatibility and ensuring proper calibration during installation are key to maintaining flight control integrity.
