CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most ICAO Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
The Civil Aviation Safety Authority or its predecessors issued AD/L200/7 affecting Morava L200 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/L200/7. The cancellation will become effective on
2 July 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, was introduced to establish and regulate civil aviation operations within Australia, with a primary focus on ensuring the safety of air navigation. The Act empowers the Governor-General to create regulations for the purposes of the Act, particularly for the safety of air navigation. Under this authority, the Civil Aviation Safety Regulations 1998 were enacted, which include provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft and aeronautical products. The ADs serve as legislative instruments, and their issuance aligns with international obligations under the Convention on International Civil Aviation, where the State of Design is responsible for the continuing airworthiness of aircraft types. CASA, as Australia’s national airworthiness authority, evaluates and, if necessary, issues Australian ADs to enforce the requirements set by the State of Design. The specific AD/L200/7 concerning Morava L200 series aeroplanes has been cancelled by CASA due to the resolution of the unsafe condition, effective from 2 July 2009, without the need for a replacement AD.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the regulation of civil aviation in Australia, with a focus on ensuring the safety of air navigation. Specifically, under section 98 of the Act, the Governor-General is empowered to make regulations for the purposes of the Act, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs are legislative instruments that must be assessed and potentially adopted by the State of Registry of an individual aircraft to ensure its continuing airworthiness. In the context of international obligations, the State of Design has overall responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to States of Registry. CASA, as Australia's national airworthiness authority, is tasked with assessing such information and issuing Australian ADs where necessary. In certain circumstances, such as the cancellation of Australian AD/L200/7 affecting Morava L200 series aeroplanes due to the resolution of an unsafe condition, CASA may decide to cancel an AD without public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The primary sections of the Civil Aviation Safety Regulations 1998 relevant to the issuance of airworthiness directives (ADs) include regulation 39.001, which allows the Civil Aviation Safety Authority (CASA) to issue such directives for specific types of aircraft or aeronautical products. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for air navigation safety, and regulation 39.001(5) specifies that an AD is a disallowable instrument under the Acts Interpretation Act 1901, making it a legislative instrument according to the Legislative Instruments Act 2003. These provisions establish the legal framework for CASA to issue ADs to ensure the continuing airworthiness of aircraft.
The Civil Aviation Safety Regulations 1998 impose several obligations and requirements on CASA and other relevant entities. Under Annex 8 of the Convention on International Civil Aviation, the State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry. The State of Registry, in turn, is responsible for ensuring the airworthiness of individual aircraft and must develop or adopt requirements to achieve this. When a State of Design issues an AD, CASA must assess the information and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. This process ensures that safety standards are uniformly applied and maintained across all aircraft registered within Australia.
In the context of specific aircraft models, such as the Morava L200 series aeroplanes, CASA has the authority to issue or cancel ADs based on assessments of airworthiness. In the case of AD/L200/7, which was issued for Morava L200 series aeroplanes, CASA has determined that the unsafe condition no longer exists, leading to the cancellation of this directive. The cancellation, effective from 2 July 2009, signifies that no replacement AD is required because the identified safety issue has been resolved. The decision to cancel the AD was made in accordance with Australia’s obligations under the Convention on International Civil Aviation, and no public consultation was deemed necessary.
The Civil Aviation Safety Regulations 1998 also outline the consequences of non-compliance with ADs. While the specific offences, penalties, or consequences for breaching an AD are not detailed in the provided text, it is understood that failure to comply with an AD could result in significant legal and safety ramifications. Given the regulatory nature of ADs, non-compliance could lead to enforcement actions, fines, or other penalties, as prescribed by the relevant aviation safety regulations and Acts. The seriousness of these consequences underscores the importance of adhering to ADs to maintain the highest safety standards in air navigation.
