data sheet; and
           (ii) in the aircraft's logbook;
 to the effect that that load data sheet has been prepared by the validation of cumulative data and not by weighing the aircraft.

3A Use of fleet weight and CG values
       3A.1 An operator of an aeroplane to which paragraph 3.2.1 refers may include it in a fleet in accordance with this subsection and operate it using the fleet (weight and CG) values.
       3A.2 When first establishing fleet (weight and CG) values, an operator must do so using the current weight and CG of each aeroplane in the fleet.
       3A.3 An operator must not include an aeroplane in a fleet unless it has been weighed within the previous 4 years to establish its weight and CG.
       3A.4 An operator who operates aeroplanes using fleet (weight and CG) values must have documented procedures for the establishment, review and use of those values. The procedures must:
(a) provide for the identification of aeroplanes in the fleet; and
(b) ensure compliance with the requirements of this subsection and subsection 3B.
       3A.5 Subject to paragraphs 3A.6, 3A.7 and 3A.8, an operator must not include in a fleet an aeroplane:
(a) whose actual operating weight varies from the fleet's average operating weight by more than 0.5% of the maximum landing weight; or
(b) whose actual CG varies from the fleet's average CG by more than 0.5% of the mean aerodynamic chord.
       3A.6 An operator may include in a fleet an aeroplane whose actual CG exceeds the maximum permitted variation under subparagraph 3A.5 (b), but only if it is operated with its individual CG.
       3A.7 An operator may include in a fleet an aeroplane that has, compared to other aeroplanes in the fleet, a physical, accurately accountable difference that causes it to exceed the maximum permitted variations under paragraph 3A.5.
       3A.8 An operator, who includes in a fleet an aeroplane to which paragraph 3A.7 applies, must make appropriate corrections when calculating the weight, CG, or both, of that aeroplane, to take account of the difference referred to in that paragraph.
       3A.9 If an operator omits an aeroplane from a fleet and does not include it in another fleet in accordance with this subsection, the operator must:
(a) operate that aeroplane with its individual operating weight and CG; and
(b) reweigh that aeroplane in accordance with paragraph 3.2.
       3A.10 An operator may have more than 1 fleet, with different fleet (weight and CG) values, for aeroplanes of the same model and configuration.
       3A.11 An operator must only include in a fleet aeroplanes for which a mean aerodynamic chord has been published.

3B Weighing aeroplanes to establish fleet (weight and CG) values
       3B.1 An operator must re-establish fleet (weight and
