- (a) The valve controlling the flow of fuel to an aircraft must have a deadman control. The deadman control device must be arranged to accommodate the operational requirements. The fuel flow control valve must be one of the following:(1) The hydrant pit valve; or(2) On the hose nozzle for overwing servicing.(b) Deadman controls must be designed to preclude defeating their intended purpose.(c) The deadman flow control in the nozzle may be used for overwing fueling.(1) Notches or latches in the nozzle handle that could allow the valve to be locked open are prohibited.(2) Each overwing servicing nozzle must have a cable with a plug or clip for bonding to the aircraft.(3) Nozzles for underwing fueling must be designed to be attached securely to the aircraft adapter before the nozzle can be opened. It must not be possible to disengage the nozzle from the aircraft adapter until the nozzle is fully closed.(d) Fuel servicing pump mechanisms must be designed and arranged so that failure or seizure does not cause rupture of the pump housing, a tank, or of any component containing fuel. Fuel pressure must be controlled within the stress limits of the hose and plumbing by means of an in-line pressure controller, a system pressure relief valve, or other suitable means. The working pressure of any system component must equal or exceed any pressure to which it could be subjected.(e) UL listed or approved dispensing devices must be used.(f) Access to dispensing equipment must be controlled by means of mechanical or electronic devices designed to resist tampering and to prevent access or use by unauthorized persons.(g) Dispensing devices must have a UL listed or approved emergency shutoff valve, incorporating a fusible link or other thermally actuated device designed to close automatically in case of fire.(1) This valve must also incorporate a shear section that automatically shuts off the flow of fuel upon severe impact.(2) This valve must be rigidly mounted at the base of the dispenser in accordance with the manufacturer's instructions.(3) Dispensing devices or cabinets must be designed so that a proper bond between the aircraft and the fueling equipment can be established.
