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 US FAA issued AD 2002-25-07, affecting Boeing 737 aircraft, in the year 2002. The USA is the State of Design for this type. As a result of a request from industry, CASA has amended the equivalent Australian AD to allow an alternative method of compliance (AMOC) to some of the requirements of the AD. This AMOC has been approved by the FAA. The amended AD, AD/737/262 Amendment 1, will become effective on 13 April 2006. This AD cancels and replaces the previous issue.
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 establish a comprehensive legal framework for ensuring the safety and efficiency of civil aviation in Australia. This legislation empowers the Governor-General to make regulations, including issuing airworthiness directives (ADs), for the purposes of the Act and in the interests of the safety of air navigation. The Act is complemented by the Civil Aviation Safety Regulations 1998, which provide the mechanism for the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. The objective of these regulations is to ensure that aircraft and aeronautical products maintain their airworthiness and comply with safety standards. The issuance of ADs is a legislative instrument that aligns with the obligations under international conventions, such as Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has overall responsibility for the continuing airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, is responsible for assessing information from the State of Design and, where appropriate, issuing corresponding ADs to ensure compliance with international safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework is designed to ensure the continuing airworthiness of aircraft registered in Australia and is aligned with the responsibilities of the State of Design and the State of Registry under Annex 8 of the Convention on International Civil Aviation. The ADs, which are legislative instruments, mandate compliance with specific safety requirements and are often issued in response to international directives, as exemplified by the amendment of AD/737/262 Amendment 1 concerning Boeing 737 aircraft. This amendment, which introduces an alternative method of compliance approved by the FAA, is effective from 13 April 2006 and cancels the previous directive. Notably, such ADs do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review, reflecting their technical nature and the global standards they aim to uphold.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for the issuance of airworthiness directives (ADs). Section 98 of the Act empowers the Governor-General to create regulations for the safety of air navigation, and regulation 39.001 of the Regulations permits the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. This is further clarified in subregulation 39.001(5), which identifies an AD as a disallowable instrument under section 46A of the Acts Interpretation Act 1901, thus classifying it as a legislative instrument under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions are multi-faceted. The State of Design, in this case, the United States for Boeing 737 aircraft, is responsible for the continuing airworthiness of the aircraft type and must provide necessary information to ensure safety. The State of Registry, which in this context is Australia, must then develop or adopt requirements to ensure the continuing airworthiness of the aircraft registered within its territory. CASA, as Australia’s national airworthiness authority, is tasked with assessing information from the State of Design and, if necessary, issuing an Australian AD to enforce the design state’s requirements.
Failure to comply with the ADs can lead to severe consequences. The Civil Aviation Act 1988 and associated regulations do not explicitly outline specific offences or penalties for non-compliance with ADs; however, non-compliance generally falls under the broader regulatory enforcement powers of CASA. CASA can take enforcement actions including grounding of aircraft, fines, and other civil or criminal penalties as deemed necessary for ensuring compliance with safety standards. These actions are intended to maintain the highest standards of airworthiness and safety in Australian aviation.
