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/AC-100/1 affecting all models of S.L. Industries Commander 100 and Volair 10 series aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/AC-100/1. The cancellation will become effective on 28 August 2008. 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, Systems and New Technologies, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate the safety aspects of civil aviation in Australia, addressing the need for a comprehensive legislative framework to ensure air safety and the proper functioning of civil aviation. This Act empowers the Governor-General to make regulations in the interests of air navigation safety, delegating specific responsibilities to the Civil Aviation Safety Authority (CASA). In line with this legislative mandate, CASA has the authority to issue airworthiness directives (ADs) for various types of aircraft and aeronautical products, as stipulated under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs serve as critical tools in maintaining the continuing airworthiness of aircraft, a responsibility that CASA, as Australia's national airworthiness authority, must uphold in accordance with international standards set by the International Civil Aviation Organization (ICAO). The enactment of this legislation ensures that Australia meets its obligations under the Convention on International Civil Aviation, particularly concerning the dissemination of continuing airworthiness information.
Scope and Application
The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, applies to the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. These regulations allow CASA to issue ADs for specific types of aircraft or aeronautical products, which are considered legislative instruments and must comply with the Legislative Instruments Act 2003. ADs are a fundamental tool for maintaining the continuing airworthiness of aircraft types and are issued by most ICAO Contracting States, including Australia. The State of Design, where an aircraft is designed, is responsible for ensuring the aircraft type's airworthiness and must provide necessary information to States of Registry, which in Australia is managed by CASA. This legislation ensures that Australia adheres to its international obligations under the Convention on International Civil Aviation, and CASA's actions are guided by these international standards. The specific AD/AC-100/1 issued by CASA for certain models of S.L. Industries Commander 100 and Volair 10 series aircraft has been cancelled due to the resolution of the unsafe condition, without the need for a replacement AD. This cancellation reflects Australia’s commitment to safety and compliance with international obligations.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations that are essential for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments, as per section 6 of the Legislative Instruments Act 2003 and subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998.
Under the Convention on International Civil Aviation, particularly Annex 8, the State of Design holds the overarching responsibility for the continuing airworthiness of an aircraft type. This includes providing necessary information to ensure the aircraft's ongoing airworthiness to the State of Registry. The State of Registry, in turn, is responsible for developing or adopting requirements to maintain the airworthiness of aircraft registered within its jurisdiction. When an AD is issued by the State of Design against a type of aircraft on the Australian Register, CASA must assess this information and, if appropriate, issue an Australian AD to enforce the requirements set by the State of Design.
The obligations imposed by these regulations on CASA and other entities include the assessment of international ADs and the issuance of corresponding Australian ADs to ensure compliance with international standards of airworthiness. CASA has the authority to cancel an AD when the unsafe condition it was intended to address no longer exists, as demonstrated by the cancellation of Australian AD/AC-100/1 for the S.L. Industries Commander 100 and Volair 10 series aircraft.
The Act does not specify penalties for non-compliance with ADs, but non-compliance can lead to severe consequences such as grounding of aircraft, which can result in significant financial and operational repercussions for the operators. CASA enforces compliance through audits and inspections, and in cases of serious non-compliance, can impose administrative penalties, which may include fines or other sanctions. The authority to issue ADs and enforce compliance is critical in maintaining the high safety standards expected in the aviation industry.
