power unit will not present a hazard and where a statement to that effect, together with any special conditions for operation, is included in the operator's operations manual if such a manual is required.
Note   For this paragraph, CASA is satisfied if the aircraft flight manual permits operation of such an engine or auxiliary power unit.
       4.3.2When an external electrical supply is used, the connections between that supply and the aircraft electrical system shall be made and securely locked before the fuelling operation is connected and shall not be disconnected until the operation has been completed, except that connectors, which provide control to ensure effective engagement before external power can be supplied to the aircraft, need not be locked.
       4.3.3A person shall not, and the pilot in command and the operator shall take reasonable steps to ensure that a person does not, during fuelling operations:
(a) operate or perform maintenance work on the aircraft's radar equipment except that where the fuel is kerosene, operation or maintenance may be carried out provided the radar transmitter is de‑activated; or
(b) except where the fuel involved is kerosene, carry out maintenance on any electrical, electronic or radio systems within the aircraft or operate such equipment other than the aircraft's interior lighting or electrical apparatus necessary for the fuelling process.
       4.3.4For fuelling an aircraft, the following requirements apply:
(a) before a fuel tank cap is removed, the aircraft and all fuelling equipment must be bonded;
(b) if bonding is lost, fuel transfer must be stopped immediately and not resumed until the bond is restored.
Note   Care must be taken before reconnecting the bonding wire to allow for dissipation of static electricity that may have built up.
       4.3.4AFor paragraph 4.3.4:
bonded means the aircraft and the fuelling equipment have the same electrical potential.
fuelling includes refuelling and defuelling.
fuelling equipment includes mobile fuel tankers, in-ground refuel ports, fuel bowsers, hand pumps, drums, funnels and other loose items of equipment if these are used in the fuelling operation.
       4.3.5All footwear worn by aircraft servicing personnel and persons operating fuelling equipment shall be of a non-sparking type and such persons shall not carry any matches, cigarette lighters or other objects which could represent an ignition hazard.
       4.3.6Except where automatic shut-off devices limit the capacity of an aircraft fuel tank, the operator and the pilot in command shall ensure that sufficient airspace remains in each fuel tank to allow for anticipated fuel expansion.
       4.3.7When a fuelling operation on an aircraft has been completed, the pilot in command and the operator of the aircraft shall ensure that all fuel and oil tank caps are securely refitted.
       4.3.8Aircraft oil tanks shall not be drained or filled when the aircraft is
