OPERATIONS 407-15 

the operator shall touch the filler cap with the nozzle spout 

before removing the cap in order to equalize the potential 

between the nozzle and the filler port. The spout shall be kept 

in contact with the filler neck until the fueling is completed. 

5.4.3* Where a funnel is used in aircraft fueling, it shall be 

kept in contact with the filler neck as well as the fueling nozzle 

spout or the supply container to avoid the possibility of a spark 

at the fill opening. Only metal funnels shall be used. 

5.4.4 Where a hydrant servicer or cart is used for fueling, the 

hydrant coupler shall be connected to the hydrant system 

prior to bonding the fuel equipment to the aircraft. 

5.4.5 Bonding and fueling connections shall be disconnected 

in the reverse order of connection. 

5.4.6 Conductive hose shall be used to prevent electrostatic discharge but shall not be used to accomplish required bonding. 

5.5 Operation of Aircraft Engines and Heaters. 

5.5.1 Fuel se-rVicing shall not be performed on a fixed wing aircraft while an on board engine is operating. (See Section .5.21.) 

Exc1Jtion: In an emergenc-y nsulting from the failun of an onboard 

auxiliary power unit on a jet aircraft and in the absence of suitable 

ground support equipment, a jet engine mounted at the rear of the 

aircraft or on the wing on the side opposite the fueling point shall be 

permitted to be operated during fueling to provide power, provided that 

th.e operation follows written procedures approved by the authority having jurisdiction. 

5.5.2 Combustion heaters on aircraft (e.g., wing and tail surface heaters, integral cabin heaters) shall not be operated during fueling operations. 

5.6 Internal Combustion Engine Equipment Around Aircraft 

(Other than Aircraft Fuel Servicing Vehicles). 

5.6.1 Equipment, other than that performing aircraft servicing functions, shall not be permitted within 15 m (50 ft) of 

aircraft during fuel servicing operations. 

5.6.2 Equipment performing aircraft servicing functions 

shall not be positioned within a 3 m ( 10 ft) radius of aircraft 

fuel system vent openings. 

5.6.3 During overwing aircraft fuel servicing where aircraft 

fuel system vents are located on the upper wing surface, equipment shall not be positioned under the trailing edge of the 

wing. 

5. 7• Electrical Equipment Used on Aircraft Servicing Ramps. 

5.7.1 Battery chargers shall not be connected, operated, or 

disconnected while fuel servicing is performed on the aircraft. 

5. 7. 2• Aircraft ground-power generators or other electrical 

ground-power supplies shall not be connected or disconnected while fuel servicing is performed on the aircraft. 

5. 7.3 Electric tools or similar tools likely to produce sparks or 

arcs shall not be used while fuel servicing is performed on the 

aircraft. 

5.7.4 Photographic equipment shall not be used within 3m 

(10 ft) of the fueling equipment or the fill or vent points of 

aircraft fuel systems. 

5.7.5 Other than aircraft fuel servicing vehicles, batterypowered vehicles that do not comply with the provisions of 

this standard shall not be operated within 3 m (I 0 ft) of fueling equipment or spills. (See Section .5. 6.) 

5.7.6* Communication equipment located outside of the cab 

of the vehicle and used during aircraft fuel servicing operations within 3m (10ft) of the fill or vent points of aircraft fuel 

systems shall be listed as intrinsically safe for Class I, Division I, 

Group D hazardous (classified) locations in accordance with 

ANSI/UL 913. 

5.8 Open Flames on Aircraft Fuel Servicing Ramps. 

5.8.1 Entrances to fueling areas shall be posted 11fi th "no 

smoking" signs. 

5.8.2 Open flames on aircraft fuel servicing ramps or aprons 

within 15 m (50 ft) of any aircraft fuel servicing operation or 

fueling equipment shall be prohibited. 

5.8.3 The category of open flames and lighted open-f1ame 

devices shall include, but shall not be limited to, the foll owing: 

(1) Lighted cigarettes, cigars, pipes 

(2) Exposed flame heaters, liquid, solid, or gaseous devices, 

including portable and wheeled gasoline or kerosen e 

heaters 

(3) Heat-producing, welding, or cutting devices and blowtorches 

( 4) Flare pots or other open-flame lights 

5.8.4 The authority having jurisdiction can establish oth er 

locations where open flames and open-flame devices shall not 

be permitted. 

5.8.5 Personnel shall not carry lighters or matches on the ir 

person while engaged in fuel servicing operations. 

5.8.6 Lighters or matches shall not be permitted on o r in 

fueling equipment. 

5.9* Lightning Precautions. 

5.9.1 Fuel servicing operations shall be suspended wh e re 

lightning flashes are in the immediate vicinity of the airport. 

5.9.2 A written procedure shall be established to set the criteria 

for where fueling operations are to be suspended at each airport 

as approved by the fueling agent and the airport authori ty. 

5.10 Aircraft Fuel Servicing Locations. 

5.10.1 Aircraft fuel servicing shall be performed outdoors. 

Aircraft fuel servicing incidental to aircraft fuel system maintenance operations shall comply with the requirements of 

NFPA410. 

5.10.2* Aircraft being fueled shall be positioned so that aircraft fuel system vents or fuel tank openings are not closer 

than 7.6 m (25 ft) to any terminal building, hangar, service 

building, or enclosed passenger concourse other than a loading walkway. Aircraft being fueled shall not be positioned so 

that the vent or tank openings are within 15 m (50ft) of an y 

combustion and ventilation air-intake to any boiler, heater, or 

incinerator room. 

5.10.3 Accessibility to aircraft by emergency fire equipment 

shall be established for aircraft fuel servicing positions. 

5.11 Aircraft Occupancy During Fuel Servicing Operations. 

5.11.1 If passengers remain on board an aircraft during fuel 

servicing, at least one qualified person trained in emergency 

evacuation procedures shall be in the aircraft at or near a doo r
