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 French DGAC has issued AD 98-277-040(A) R1 affecting SA 315 model helicopters. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/SA 315/3, which will become effective on 23 November 2006.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to ensure the safety and efficiency of civil aviation in Australia and to implement Australia's obligations under the Convention on International Civil Aviation. This Act empowers the Governor-General to make regulations that support air navigation safety, including the issuance of airworthiness directives (ADs). These ADs are crucial for maintaining the continuing airworthiness of aircraft and aeronautical products, ensuring compliance with international standards. The Civil Aviation Safety Regulations 1998 further detail the process and authority for issuing ADs, which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. The policy objective of the Act is to uphold stringent safety standards in civil aviation, aligning with global regulatory practices as outlined in the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA), acting as Australia's national airworthiness authority, is responsible for assessing international ADs and issuing corresponding directives to mandate safety requirements for aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, applies to all persons, entities, and industries involved in civil aviation within Australia, with a particular focus on ensuring the airworthiness of aircraft. Specifically, the Act empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) which serve as mandatory requirements to maintain the continuing airworthiness of aircraft types registered in Australia. These ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and are developed in accordance with Australia's obligations under the Convention on International Civil Aviation. While ADs are issued in response to international safety directives from the State of Design, they are subject to review and adoption by CASA, ensuring compliance with Australian safety standards. Notably, this process does not require public consultation as it pertains to international obligations and is aimed directly at maintaining safety standards. The ADs are issued by CASA, reflecting Australia's commitment to harmonising international civil aviation safety standards.
Key Provisions
The main operative sections of the Civil Aviation Safety Regulations 1998, particularly regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (section 39.001(5)). An AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and it is classified as a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003. This means that CASA has the authority to create these directives to ensure the safety and airworthiness of aircraft in Australia.
The obligations imposed by the Act and the Regulations on CASA and the State of Registry are primarily focused on ensuring the continuing airworthiness of aircraft. CASA, as Australia’s national airworthiness authority, must assess any ADs issued by the State of Design, which is the country responsible for the design of the aircraft type. If an AD is deemed necessary, CASA must issue an Australian AD to enforce the requirements set by the State of Design. The State of Registry is responsible for ensuring that each aircraft under its registry meets the continuing airworthiness standards, which involves adhering to any relevant ADs. These obligations ensure that all aircraft in Australia meet international safety standards and that any identified safety issues are promptly addressed.
Breach of the requirements set out in an AD can lead to serious consequences. Although specific offences and penalties are not detailed in the provided text, it is clear that failure to comply with an airworthiness directive can result in significant civil or criminal consequences. The severity of these penalties can vary depending on the nature and extent of the breach. Typically, non-compliance with ADs can lead to enforcement actions by CASA, which may include fines, suspension, or revocation of an aircraft's certificate of airworthiness. Such actions are intended to ensure that all aircraft operating in Australia meet the highest safety standards, thereby protecting the public and maintaining the integrity of the aviation industry.
