- 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.
- Turn off the ignition switch after the servicing vehicle or equipment is parked, brakes set, and before wheels are chocked, except equipment using PTO to drive the pump.
- 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.
- Fuel servicing supervisor notifies refueling operator when reduced flow required.
Filling Fuel Servicing Vehicles From Hydrant Systems
- Follow stated distance criteria and established procedures in the cited technical orders.
Servicing in Aircraft Alert, Hardened/Protective Aircraft Shelters, or Flow Through Revetments (FTRs)
- Cease operations, notify fire department, and evacuate non-essential personnel in emergency situations.
- Comply with fuel servicing safety zones.
- Place refueling vehicle at maximum hose length, unless otherwise noted.
- Ensure fire protection equipment is readily available.
- Non-essential equipment/personnel removed from area.
- Powered vehicles are often shut down and parked outside the shelter when possible, with all aircraft doors open.
- Electrical systems compliance: Class 1 Division 1 or 2 per specific requirements
- Doors will remain open during refueling operations.
- Special conditions apply during certain situations inside shelters
Unique Requirements When Servicing in Hardened/Protective Aircraft Shelters (HAS/PAS)
- Facility must comply with electrical requirements outlined in DoD Unified Facility Criteria.
- Specific electrical requirements differ for first, modified first, second, and third generation shelters.
- Location of equipment/personnel within shelter is critical, depending on configuration.
Aircraft Fuel Servicing in Type A/F 37T10/11 Hush Houses
- Fuel servicing only permitted after aircraft engine runs are completed to avoid fuel depletion.
- Other operations cease during fuel servicing.
- All personnel doors are closed except those for control room/related areas..
Fuel Servicing Explosives-Loaded Aircraft
- Refueling should normally precede munitions or explosives loading.
- Restrictions apply to aircraft with different types of munitions, and special locations such as “hot cargo pads”
- Authorization requirements from relevant aircraft manuals may be needed and should be adhered to.
Fuel System Maintenance Facilities
- Fuel servicing is allowed when facility complies with requirements of applicable technical orders.
