free water since sensory perceptions of colour and smell, if used alone, can be quite misleading.
Note 3   In the case of turbine fuels, attention is also drawn to the necessity of watching for signs of cloudiness or other indication of the presence of suspended water droplets which will not necessarily be detected by the means mentioned in Note 2.
       3.4All fuel shall be strained or filtered for the removal of free or suspended water and other contaminating matter before entering the aircraft tanks.
Note   Attention is drawn to the special standards of filtration which may be specified by the manufacturers of certain types of engines. e.g. turbine engines and direct-injection piston engines.
4 Fuelling of aircraft

4.1 Location of aircraft
       4.1.1During fuelling operations, the aircraft and ground fuelling equipment shall be so located that no fuel tank filling points or vent outlets lie:
(a) within 5 metres (17 ft) of any sealed building; and
(b) within 6 metres (20 ft) of other stationary aircraft; and
(c) within 15 metres (50 ft) of any exposed public area; and
(d) within 15 metres (50 ft) of any unsealed building in the case of aircraft with a maximum take-off weight in excess of 5 700 kg (12 566 lb) and
(e) within 9 metres (30 ft) of any unsealed building in the case of aircraft with a maximum take-off weight not exceeding 5 700 kg (12 566 lb).
       4.1.1.1Notwithstanding the contents of paragraph 4.1.1 limited fuelling operations for maintenance purposes may be carried out in certain hangars under the following conditions:
(a) refuelling or defuelling of gasoline or wide-cut gasoline type turbine fuel is not permitted;
(b) overwing fuelling is not permitted;
(c) these operations shall not be permitted in hangars occupied by 2 or more tenants;
(d) the operator shall obtain approval from CASA for the detailed procedures under which these operations may be performed. These procedures shall be described in the maintenance manual and shall include the circumstances under which refuelling or defuelling in hangars or maintenance area is permitted, and the maximum volume of fuel involved.
       4.1.1.2For the purpose of this Order, a sealed building is one which all the external part within 15 metres (50 ft) of an aircraft's fuel tank filling points or vent outlets or ground fuelling equipment is of non-flammable materials and has no openings or all openings are closed.
       4.1.2Where the fuelling equipment is not mobile, the aircraft shall be so placed that it can be rapidly moved to a place of safety, and a means of ensuring that this can be done shall be readily available.
Note   The following operations are not deemed to constitute fuelling operations:
(a) the drainage of a small
