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 United States FAA has issued AD 71-21-04 affecting General Dynamics 340/440 series aeroplanes. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/CONVAIR/26, which will become effective on 26 October 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, New Technologies and Systems, 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, enacted by the Parliament of Australia, aims to ensure the safety of air navigation through comprehensive regulation of civil aviation. This legislation grants the Governor-General the authority to establish regulations under section 98, which are integral to maintaining the safety standards necessary for the aviation industry. The Civil Aviation Safety Regulations 1998 further empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001. These ADs are legislative instruments subject to disallowance, as outlined in section 46A of the Acts Interpretation Act 1901, and are mandated by section 6 of the Legislative Instruments Act 2003. The ADs are crucial for ensuring the continuing airworthiness of aircraft types, aligning with Australia’s obligations under Annex 8 to the Convention on International Civil Aviation, where the State of Design has a responsibility to provide necessary information. CASA, as Australia’s national airworthiness authority, assesses this information and issues corresponding Australian ADs when required, such as in the case of AD/CONVAIR/26 issued in response to FAA's AD 71-21-04.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. This regulatory framework is designed to ensure the safety of air navigation in Australia and aligns with international standards as set out in Annex 8 to the Convention on International Civil Aviation. ADs are legislative instruments that mandate specific requirements to maintain the airworthiness of aircraft. These directives apply to aircraft registered in Australia and are issued in response to ADs from the State of Design, which is the country where the aircraft type was designed. For example, in response to the United States Federal Aviation Administration’s AD 71-21-04 for General Dynamics 340/440 series aeroplanes, CASA issued AD/CONVAIR/26, effective from 26 October 2006. Given that these directives are issued under international obligations and in response to actions by the State of Design, no public consultation is required, and they do not necessitate a Regulatory Impact Statement. This legislative approach ensures that Australia meets its international commitments while maintaining the highest safety standards for its civil aviation operations.
Key Provisions
Under the Civil Aviation Act 1988, specifically section 98, the Governor-General is empowered to make regulations aimed at ensuring the safety of air navigation. This regulatory framework allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as outlined in regulation 39.001 of the Civil Aviation Safety Regulations 1998. An AD, as described in subregulation 39.001(5), is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus qualifies as a legislative instrument under section 6 of the Legislative Instruments Act 2003. ADs are a key mechanism for maintaining the continuing airworthiness of aircraft types, as mandated by Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these regulations are multifaceted. The State of Design, which is the country where an aircraft type is designed, bears the primary responsibility for ensuring the continuing airworthiness of that type. This includes providing necessary information to States of Registry to help maintain airworthiness. Conversely, the State of Registry, which is the country where the aircraft is registered, must implement measures to ensure the ongoing airworthiness of individual aircraft. When a State of Design issues an AD, the State of Registry, in this case CASA, must assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This collaborative approach ensures that airworthiness directives are harmonised and enforced across international borders.
Failure to comply with the airworthiness directives issued under this regulatory framework can result in significant consequences. Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 establish stringent measures and penalties for non-compliance. Penalties for breaching these regulations can include substantial fines and, in severe cases, criminal charges. The exact penalties depend on the nature and severity of the breach but can be severe, reflecting the critical importance of adhering to airworthiness directives in maintaining the safety of air navigation. This stringent approach underscores the importance of compliance to ensure the highest standards of aviation safety are maintained.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust framework for issuing and enforcing airworthiness directives. The State of Design and State of Registry bear shared responsibilities in maintaining the airworthiness of aircraft, with CASA playing a pivotal role in issuing and enforcing ADs in Australia. Non-compliance with these directives can lead to significant civil and criminal penalties, reinforcing the critical importance of adhering to these regulations to ensure aviation safety.
