The transfer of fuel from an aircraft to a tank vehicle through a hose generally is similar to fueling, and the same requirements shall apply. In addition, each operator shall establish procedures to prevent the overfilling of the tank vehicle, which is a special hazard when defueling (see 4.3.21.7 of NFPA 407). [407:5.14.1]
There shall be a procedure to eliminate air ingested during a defueling operation prior to the aircraft fuel servicing tank vehicle being reused. [407:5.14.1.1]
Where draining residual fuel from aircraft tanks incidental to aircraft fuel system maintenance, testing, manufacturing, salvage, or recovery operations, the procedures of NFPA 410 shall apply. [407:5.14.2]
The fueling operator shall monitor the panel of the fueling equipment and the aircraft control panel during pressure fueling or shall monitor the fill port during overwing fueling. [407:5.15.1]

Aircraft fueling hose shall be inspected before use each day. The hose shall be extended as it normally would be for fueling and checked for evidence of blistering, carcass saturation or separation, cuts, nicks, or abrasions that expose reinforcement material, and for slippage, misalignment, or leaks at couplings. If coupling slippage or leaks are found, the cause of the problem shall be determined. Defective hose shall be removed from service. [407:5.16.1]
At least once each month the hose shall be completely extended and inspected as required in 42.10.5.16.1. The hose couplings and the hose shall be examined for a length approximately 12 in. (305 mm) adjacent to the couplings. Structural weakness shall be checked by pressing the hose in this area around its entire circumference for soft spots. Hoses that show evidence of soft spots shall be removed from service. The nozzle screens shall be examined for rubber particles. The presence of such particles indicates possible deterioration of the interior, and the hose shall be removed from service. With the hose still completely extended, it shall be checked at the working pressure of the fueling equipment to which it is attached. Any abnormal twisting or ballooning during this test indicates a weakening of the hose carcass, and the hose shall be removed from service. [407:5.16.2]
A hose assembly that has been subjected to abuse, such as severe end-pull, flattening or crushing by a vehicle, or sharp bending or kinking, shall be removed from service. The hose assembly that has been subjected to abuse shall be hydrostatically tested prior to use. (See 4.2.2.1 of NFPA 407.) [407:5.16.3]
If inspection shows that a portion of a hose has been damaged, the damaged portion shall be cut off and the undamaged portion recoupled. Two lengths of hose shall not be coupled together. Only couplings that are an exact match for the interior and exterior dimensions of the hose shall be used. Recoupled hose assemblies shall be hydrostatically tested. (See 4.2.2.1 of NFPA 407.) [407:5.16.4]
Before any hose assembly, new or recoupled, is placed in service, it shall be visually inspected for evidence of damage or deterioration. [407:5.16.5]
Kinks or short loops in fueling hose shall be avoided. [407:5.16.6]
Suitable records shall be kept of required inspections and hydrostatic tests. [407:5.16.7]

The engine of the tank vehicle shall be shut off before starting to fill the tank. [407:5.20.1.4]
To prevent leakage or overflow from expansion of the contents due to a rise in atmospheric temperature or direct exposure to the sun, no cargo tank or compartment shall be loaded to the point where it is liquid full. [407:5.20.1.5]
Where loading tank trucks through open domes, a bond shall be established between the loading piping and the cargo tank to equalize potentials. The bond connection shall be made before the dome is opened and shall be removed only after the dome is closed. [407:5.20.2.1]
Drop tubes attached to loading assemblies extending into the vehicle tank shall extend to the bottom of the tank and shall be maintained in that position until the tank is loaded to provide submerged loading and avoid splashing or free fall of fuel through the tank atmosphere. The flow rate into the tanks shall not exceed 25 percent of the maximum flow until the outlet is fully covered. [407:5.20.2.2]
The level in the tank shall be visually monitored at all times during top loading. [407:5.20.2.3]
A bonding connection shall be made between the cargo tank and the loading rack before any fuel connections are made and shall remain in place throughout the loading operation. [407:5.20.3.1]
The operator shall initiate fuel flow by means of a deadman control device. [407:5.20.3.2]

  3. Passengers shall not board or deboard during rapid refueling operations.
  4. Only designated personnel, properly trained in rapid refueling operations, shall operate the equipment. Written procedures shall include the safe handling of the fuel and equipment.
