       3B.3 An operator must re-establish the fleet (weight and CG) values by using the weights and CG of those aeroplanes that have been weighed in accordance with paragraph 3B.2.
       3B.4 An operator must ensure that the aeroplanes that have not been weighed for the longest time are selected when the weighing of aircraft in a fleet is undertaken for the purposes of paragraphs 3B.1 and 3B.2.
       3B.5 Each aeroplane in a fleet must be weighed at least once every 9 years.

4 Weighing procedure
       4.1 Aircraft weighings must be carried out under the control of a weight control officer whose appointment covers the activity, or a person referred to in paragraph 4.1A.
Note   Subject to compliance with paragraphs 4.1 and 4.7, a person, other than a weight control officer, may carry out the weighing of an aircraft.
       4.1A A person may carry out the weighing of aircraft and prepare a weighing summary for aircraft (other than power-assisted sailplanes, powered sailplanes or sailplanes) that are to be certified under regulation 21.190 and 21.195A of CASR for a purpose mentioned in paragraph 21.191 (g), (h) or (j) of CASR if the person:
(a) has successfully completed an aircraft weighing procedures course approved by CASA within the last 2 years; and
(b) has had practical experience in setting the aircraft up in the levelled or flying position for the purpose of conducting symmetry checks, rigging angles and control surface travels, if applicable; and
(c) weighs the aircraft on scales that are approved by CASA or an organisation that has been approved by CASA for the purpose of this subparagraph; and
(d) ensures flight tests are conducted in accordance with paragraphs 91.875 (2) (f) to (j) of CASR with the aircraft at maximum and minimum permitted take-off weights and loaded so that it is tested at forward and aft CG limits; and
(e) complies with any other condition that CASA deems necessary.
       4.2 Aircraft must be weighed on scales that:
(a) have an accuracy over the temperature range for which the scales are designed of:
           (i) 0.2% of the applied load; or
           (ii) 2 kg;
 whichever is the greater; and
(b) are of a type suitable for the purpose.
       4.3 A scale mentioned in paragraph 4.2 may be used to weigh an aircraft only if it was calibrated, within the 12 month period ending on the date the scale is used to weigh the aircraft, by:
(a) the manufacturer of the scales; or
