Study Notes

Powered Support Equipment (SE) Operation

All non-essential SE must be shut down before servicing.
SE should be parked outside fuel servicing safety zone (FSSZ) and 10 feet from any aircraft.
Exceptions exist for munitions loaders/jammers during CSOs or ICTs, allowing passage underneath fuel vent outlets, but not parking there.
Consider wind direction, ramp, mechanical strain, and fuel source location when positioning SE.
Exhaust outlets should not be pointed at the aircraft.
Operators must remain near the operating SE.
Avoid touching hot exhaust manifolds.
Do not refuel SE while operating or with a hot manifold/piping.
Do not start SE when fuel vapors are present.
External tank transfers to SE internal tanks are not refueling, only if the SE is designed to perform this task.

Fuel/Water Servicing Vehicle Operation

Vehicles should not park closer than 25 feet from aircraft, unless a spotter is used for directing.
Exceptions to 25-foot rule exist for specific aircraft (AN-124, B-1, etc.) allowing positioning under horizontal stabilizers while maintaining at least a 10-foot clearance.
Specific exceptions apply to A-10, AN-124, C-5, C-17, C-130, C-135, E-4B, VC-25, Boeing 747, C-27, and U-2R; allowing vehicle within 10 feet, but not closer than 4 feet from the aircraft.
Minimize 5-foot clearance between fuel servicing vehicles and any part of the aircraft during regular operations, except when in HAS/PAS.
Special exceptions apply for R-11 fuel servicing vehicles within HAS/PAS, and high-lift platform hydrant servicing trucks.
Maintain a clear path in front of vehicles for emergency evacuation. Specific exceptions for B52 hydrant servicing.
When approaching an aircraft, do so parallel to the wings, unless the aircraft layout necessitates another approach.
Stop vehicles 25 feet away, preferably uphill; move into servicing position on signal.
Use spotters and chocks when backing and for any vehicle that is not exempt from chocks.
Chocks must be compliant with MIL-PRF-32058.

Aircraft Refueling

Mandatory use of operational checklists.
Non-essential personnel should leave FSSZ.
APU/GTC use during fueling is restricted to certain aircraft.

When refueling by "over the wing/open port" method bond the nozzle to the aircraft before removing the fill cap.
Ground/bond refueling vehicle and equipment to aircraft.
Check strainer coupling for positive locking before pressurizing the hose.
Ensure the nozzle is securely locked before pressurizing hose. Otherwise, the nozzle is defective and must be removed from service.
Fuel servicing supervisor ensures proper SPR nozzle connection for single-point servicing.
SPR nozzle types (D-1, D-2, D-3) have specific applications for fuselage or underwing servicing. Refer to table for specifics.
Workstands and other equipment not needed for servicing must be clear of the aircraft..
Complete connections for intercoms, auxiliary power, and portable refueler panels before fuel transfer.

Multiple Source Refueling

Usually, one truck services the aircraft.
Concurrent multi-truck or truck-hydrant fueling prohibited on medical evacuation craft with patients.
Fuel flow meters must be actively monitored for backflow and other issues
Defuel Override Valve must be in off position and locked, and red protective cover closed.
Maintain necessary contact between fuel servicing supervisor and panel operators.
Adhere to specific technical orders for multiple fueling procedures.

Aircraft Defueling

Maximum defueling rate is 300 GPM, to prevent overflow.
Maintenance personnel shall drain water from aircraft sumps before defueling..
Check fuel grade, especially after fuel cell maintenance or if alternate fuel was last used.
Do not pressurize hoses with the single point nozzle open.
Ensure high-level shut-off operational on refueler.
For all other units, ground personnel are on the unit to monitor fuel levels.

APU/GTC Use During Refueling and Defueling

APU/GTC use is permitted for specific aircraft.
One person at the APU/GTC controls at all times, preferably on a ground control panel, unless APU has shutdown capability in case of fire/overheat.
constant communication between cockpit, supervisor, and servicing crew is required for immediate shutdown.
Fuel servicing sources should avoid being within 50 feet of operating APUs/GTCs, except for C-5 and C-17.
Start APU/GTC in a stable condition before pressurizing refueling hose or pantograph.

Initial Filling Operations of Aircraft with Foam-Filled Tanks

Reduced flow rate refueling is required for newly/recently repaired aircraft with vapor-free bladder tanks.
