Explanatory Statement

Civil Aviation Regulations 1988

Exemption  maximum take-off weight requirements in flight manuals or other documents (agricultural or restricted category aircraft)

 

Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations.

 

Under subregulation 308 (1) of the Civil Aviation Regulations 1988 (CAR 1988), CASA may, among other things, exempt an aircraft or category of aircraft, or persons associated with the operation of those aircraft, from compliance with specified provisions of CAR 1988. Subregulation 308 (3) provides that such an exemption is subject to the aircraft complying with any conditions specified by CASA as being necessary in the interests of safety. Under subregulation 308 (4), such an exemption is a disallowable instrument for section 46A of the Acts Interpretation Act 1901.

 

Under subregulation 235 (11) of CAR 1988, operators and pilots in command of single engine aeroplanes engaged in private or aerial work operations, and having a certificate of airworthiness in the agricultural category or in the restricted category, and a permanently installed jettison system to allow the pilot in command to jettison in flight the contents of a hopper or vessel, have been granted an exemption from compliance with the requirements of subregulation 235 (4) of CAR 1988. Subregulation 235 (4) requires weight at take-off not to exceed the maximum take-off weight (MTOW) calculated under that regulation.

 

This instrument is a consequential instrument that prevents pilots in command of aircraft who have been exempted from compliance with subregulation 235 (4) from breaching the requirements of regulation 138 of CAR 1988 in respect of the MTOW specified in the aircraft’s flight manual.

 

Under this exemption, a pilot in command of a specified aeroplane is only exempted from complying with the MTOW contained in a flight manual for the aeroplane, i.e. he or she will have to continue to observe all other limitations, procedures and instructions in the flight manual.

 

Legislative Instruments Act

Subregulation 308 (4) of CAR 1988 declares an exemption to be a disallowable instrument. Under subparagraph 6 (d) (i) of the Legislative Instruments Act 2003 (the LIA), an instrument is a legislative instrument for section 5 of the LIA if it is declared to be a disallowable instrument in legislation in force before the commencement of the LIA. The exemption is, therefore, a legislative instrument and is subject to tabling and disallowance in the Parliament under sections 38 and 42 of the LIA.

 

Consultation

Consultation under section 17 of the LIA has not been undertaken in this case. The instrument is the same as an expired exemption previously issued for the same categories of aircraft (CASA EX33/2004) and is intended to facilitate operations under the primary instrument of exemption issued under subregulation 235 (11) of CAR 1988. The take-off of the aircraft mentioned at a weight that exceeds the estimated MTOW is normal in the course of agricultural operations involving use of a hopper or vessel.

 

The instrument commences on the day after it is registered. It stops having effect at the end of March 2009.

 

The instrument has been made by the Deputy Chief Executive Officer, Operations, delegate of CASA, under subregulation 7 (1) of CAR 1988.

 

[Instrument number CASA EX09/07]

Overview

The Civil Aviation Regulations 1988, as amended by the instrument F2007L00597, address the problem of ensuring that agricultural or restricted category aircraft, which are exempted from certain maximum take-off weight (MTOW) requirements, do not contravene the MTOW specified in their flight manuals. Enacted by the Australian Government, this instrument empowers the Civil Aviation Safety Authority (CASA) to issue exemptions under Section 98 of the Civil Aviation Act 1988, aiming to maintain safety standards while facilitating efficient agricultural operations. The policy objective is to support the safe operation of aircraft used in these specific sectors by allowing flexibility in certain regulatory requirements, provided safety is not compromised. This legislative instrument is a consequential measure to ensure compliance with flight manual specifications for MTOW while allowing exemptions from other weight-related constraints.

Scope and Application

The Civil Aviation Regulations 1988 (CAR 1988) provide the framework for aviation safety in Australia, and section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make these regulations. Subregulation 308(1) of CAR 1988 allows the Civil Aviation Safety Authority (CASA) to exempt specific aircraft or categories of aircraft, or persons associated with their operation, from compliance with certain provisions of CAR 1988, provided safety is not compromised. Such exemptions are subject to conditions specified by CASA under subregulation 308(3), and these exemptions are disallowable instruments under subregulation 308(4) of CAR 1988. This particular exemption pertains to single engine aeroplanes engaged in private or aerial work operations, holding a certificate of airworthiness in the agricultural or restricted category, and equipped with a permanently installed jettison system. Operators and pilots in command of these aircraft are exempt from the requirement in subregulation 235(4) of CAR 1988 to not exceed the maximum take-off weight (MTOW) calculated under that regulation, provided they comply with other specified conditions and limitations in the aircraft's flight manual. This exemption is a consequential instrument designed to prevent pilots from breaching the requirements of regulation 138 of CAR 1988 concerning the MTOW specified in the flight manual. It applies to specified aeroplanes and exempts only from the MTOW in the flight manual, while requiring observance of all other limitations, procedures, and instructions. This exemption is a legislative instrument under the Legislative Instruments Act 2003, subject to tabling and disallowance in Parliament. It comes into effect on the day after registration and ceases at the end of March 2009, having been made by the Deputy Chief Executive Officer, Operations, delegate of CASA under subregulation 7(1) of CAR 1988.

Key Provisions

The Civil Aviation Regulations 1988 (CAR 1988) contain provisions that allow the Civil Aviation Safety Authority (CASA) to exempt certain aircraft and operations from specific regulatory requirements, provided safety conditions are met. According to subregulation 308(1) of CAR 1988, CASA has the authority to exempt aircraft or categories of aircraft, or individuals associated with their operation, from specified provisions of the regulations. This exemption is detailed in subregulation 308(3), which stipulates that it is contingent upon the aircraft meeting any conditions CASA deems necessary for safety reasons. Furthermore, subregulation 235(11) of CAR 1988 specifically exempts single engine aeroplanes operating under an agricultural or restricted category certificate of airworthiness, and equipped with a jettison system, from the requirement to adhere to the maximum take-off weight (MTOW) stipulated in subregulation 235(4). The obligations imposed by these provisions on the relevant parties include ensuring that any exempted aircraft meet the specified safety conditions set by CASA. Operators and pilots in command must adhere to all other limitations, procedures, and instructions outlined in the aircraft's flight manual, even if they are exempt from the MTOW requirements. This means they must maintain strict compliance with all other operational standards to ensure flight safety. Additionally, any exemptions granted are subject to tabling and disallowance in Parliament, as per the Legislative Instruments Act 2003 (LIA). In terms of consequences for non-compliance, the legislation does not explicitly state civil or criminal penalties for breaching the exemptions or conditions. However, the overarching principle is that failure to adhere to the stipulated conditions could potentially lead to safety risks, which might result in regulatory action against the operator or pilot. The exemption is also a disallowable instrument under subregulation 308(4) of CAR 1988, meaning that it can be reviewed and potentially disallowed by Parliament if it does not meet legislative requirements. The exemption is effective from the day after its registration and ceases to have effect at the end of March 2009, underscoring the temporary nature of the regulatory flexibility provided.
