2          Commencement             This instrument commences on the day after it is registered.
3          New Civil Aviation Order 100.96             Civil Aviation Order 100.96 is repealed and a new Civil Aviation Order 100.96 substituted as set out in Schedule 1.
Schedule 1          Civil Aviation Order 100.96
Administration and procedure — weight control of balloons 1          Definitions    1.1     In this Order:             balloon, for calculating empty weight, comprises only the following: (a)   an envelope; (b)   a basket; (c)   a burner (if any).              balloon component means the envelope, basket or burner mentioned in the definition of balloon.             basket includes the equipment and instruments required under civil aviation legislation to be carried for the airworthiness of the balloon and the safe performance of an operation.             civil aviation legislation means the Civil Aviation Act 1988 and any subordinate instrument made under it.             empty weight of a balloon for an operation means the weight of the balloon used in the operation, as determined in accordance with this Order.             MA holder means a maintenance authority holder and is a person holding a maintenance authority issued under paragraph 33B (1) (a) of the Civil Aviation Regulations 1988 (CAR 1988) with privileges that include the weight control of balloons.             operating weight of a balloon for an operation means: (a)   the empty weight of the balloon; and (b)   the weight of everything else, including people (additional weight), that is:              (i)  in, on, or attached to, the balloon; and             (ii)  not included in the empty weight of the balloon. Note   Additional weight is taken to include the weight of the flight crew and the passengers, their luggage and personal effects, the fuel tanks and the fuel, and the ballast, as well as any equipment or instruments not included in the empty weight.             weighing summary means the document used to calculate the operating weight of a balloon for an operation and that lists the empty weight of the balloon, including the weight of each balloon component.             weight control of a balloon means: (a)   the determination of the empty weight of the balloon, including the weight of each balloon component; and (b)   the recording of weight alterations.             WCO means a weight control officer and is a person holding an airworthiness authority issued under paragraph 33B (1) (e) of CAR 1988 that applies for balloon weighing.    1.2     For this Order, a person is taken to be an MA holder with privileges that include the weight control of balloons if the person: (a)   holds a balloon maintenance authority under paragraph 33B (1) (a) of CAR 1988; and (b)   has a certificate from a WCO that the person has satisfactorily completed at least 1 weighing of a balloon under the supervision of the WCO. 2          Initial weighing    2.1     The initial weighing and subsequent weighing of a balloon for the purpose of determining the empty weight for an operation must: (a)   be in accordance with subsection 3 of this Order; and (b)   in the case of initial weighing, take place before any certificate of airworthiness or experimental certificate has been issued for the balloon.    2.2     CASA may require a balloon that has been weighed to be reweighed if there is a reasonable doubt about the accuracy of the weight data submitted for the balloon. Note   The operating weight (i.e. the empty weight plus the additional weight) must not exceed the maximum take-off weight for the balloon. 3          Weighing procedures    3.1     The operator and the pilot in command of a balloon must not allow the balloon to take-off unless the weighing procedures mentioned in this subsection have been completed for each balloon component.    3.2     The weighing summary for a balloon must list each of the specific balloon components included in the empty weight and state the weight of each component.    3.3     The empty weight of the balloon, including the weight of each balloon component: (a)   is to be certified as correct and entered in the weighing summary by the MA holder or WCO; and (b)   may only be so certified and entered:              (i)  following at least 2 consecutive and consistent weighings; and             (ii)  if the MA holder or WCO is satisfied with the accuracy of the weighing.    3.4     Each balloon weighing must be carried out under the control of an MA holder or a WCO whose authority covers the weighing of the balloon.    3.5     Each balloon must be weighed on scales that: (a)   the MA holder or WCO considers are suitable; and (b)   over the temperature range for which the scales are designed — are accurate to within:              (i)  plus or minus 2 kg of the applied load up to 1 000 kg; and             (ii)  plus or minus 0.2% of the applied load above 1 000 kg.    3.6     Each scale must last have been calibrated: (a)   in accordance with the procedures required or recommended by:              (i)  the manufacturer of the scales; or             (ii)  the government authority for weights and measures in the place where the scales are used; and (b)   within the period:              (i)  that is: (A)    5 years; or (B)    if either the manufacturer or government authority recommend a shorter period — the shortest recommended period;                   before the weighing; or             (ii)  if within the period 5 years (or the shortest recommended period) before the weighing, the scales have been affected by an occurrence likely to upset calibration — between the occurrence and the weighing. 4          Record of empty weight alterations    4.1     A complete, continuous and current record of changes in the empty weight of a balloon, including a balloon component, must be maintained and recorded in the balloon log book or other approved alternative to the log book.    4.2     The balloon must be reweighed if: (a)   the empty weight alters by more than 5 kg as a result of repairs to, or maintenance on, the balloon, including a balloon component; and (b)   the repairs, or maintenance, are of such a nature that the subsequent empty weight of the balloon cannot be accurately substantiated by calculation.    4.3     A new weighing summary and record of empty weight alteration must be prepared after each weighing. 5          Current empty weight             When determining the empty weight or operating weight of a balloon in a particular configuration, the operator and the pilot in command must use the current weighing summary that includes each balloon component for that configuration.
