changes.
       6.2 A new record of weight alterations must be raised after each weighing.
       6.3 Unless otherwise agreed to by CASA, the load data sheet for an aircraft must be renewed before further flight whenever, as the result of a modification or as otherwise shown in the record of weight alterations, changes exceeding the following have occurred:
(a) for aeroplanes:
           (i) the empty weight has changed by more than 0.5% of the MTOW or 10 kg, whichever is the greater; or
           (ii) the empty weight CG has changed by more than 2% of the maximum permissible centre of gravity range or 5 mm, whichever is the greater; and
(b) for rotorcraft:
           (i) the empty weight has changed by more than 1% of the MTOW or 10 kg, whichever is the greater; or
           (ii) the empty weight CG has changed by more than 10 mm or 10% of the maximum permissible centre of gravity range, whichever is the lesser.
       6.4 Whenever, under the circumstances described in paragraph 6.3 of this subsection, a load data sheet is renewed, the need for the corresponding introduction of a loading system, or loading system revision, must be determined in accordance with the provisions of paragraph 5.2 (3) of this section.
       6.5 Further to the provisions of paragraph 6.1 of this subsection, if CASA considers that adequate weight control has not been exercised over an aircraft, CASA may require that the aircraft be weighed or reweighed, as applicable, and a new empty weight and empty weight CG determined.
       6.7 Loading data renewed in accordance with this section must be based on the new empty weight and empty weight CG and must be prepared and approved in accordance with paragraph 5.2 (3) of this section.

7 Current empty weight
       7.1 For the purposes of a direction under regulation 235 of CAR setting out the method of estimating with respect to an aircraft at any time the relevant weight and CG, the applicable empty weight and empty weight CG must be the empty weight and empty weight CG most recently determined and specified in a load data sheet for the aircraft, in accordance with this or previous issues of this section.
Note   CASA publication Weight Control of Aircraft provides guidance on acceptable weight control methods.
