TROUBLESHOOT THIS SYSTEMDefine the reported symptom, confirm aircraft and configuration applicability, then follow current approved fault-isolation and maintenance data.
Why it exists
Store usable fuel safely and deliver it to engines or auxiliary systems while providing accurate quantity and system control.
What belongs here
- Fuel tanks and structure
- Boost and transfer pumps
- Valves and manifolds
- Fuel quantity indication
- Vent and surge systems
- Refuel and defuel panels
- Crossfeed or transfer control
- Fuel-jettison equipment where installed
What users may see
Fuel quantity, tank temperature, pump and valve status, imbalance, low pressure, refuel-panel indications and system messages may be shown.
What technicians commonly evaluate
Fuel safety, bonding and grounding, contamination, leak detection, tank-entry controls, quantity-system calibration, pump cooling and configuration-specific transfer logic are major concerns.
