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 European Aviation Safety Authority (EASA) has issued AD 2008-0035-E affecting Eurocopter AS332 model helicopters. EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/S-PUMA/74, which will become effective on 25 February 2008.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes 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 establish a comprehensive legal framework for the regulation of civil aviation in Australia, addressing issues related to safety, airworthiness, and the operation of aircraft within Australian airspace. The Act empowers the Governor-General to make regulations, such as those found in the Civil Aviation Safety Regulations 1998, which delegate the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) to ensure the ongoing safety of aircraft and aeronautical products. These ADs are critical for maintaining the airworthiness of aircraft, in line with the obligations Australia has under the Convention on International Civil Aviation. The policy objective of this legislation is to harmonise Australia's aviation safety standards with international practices, thereby protecting public safety and facilitating smooth cross-border operations. The issuance of ADs, such as the Australian AD/S-PUMA/74 in response to EASA's AD 2008-0035-E, exemplifies the practical application of these regulations to address specific safety concerns as identified by the State of Design.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish a framework for ensuring the safety of air navigation in Australia. These instruments empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs), which are legislative instruments designed to mandate safety requirements for specific types of aircraft or aeronautical products. This authority is exercised under regulation 39.001 of the Civil Aviation Safety Regulations 1998, which aligns with the international standards set by the International Civil Aviation Organization (ICAO) through Annex 8 of the Convention on International Civil Aviation. The ADs issued by CASA are a reflection of the State of Design's responsibilities, with CASA acting as Australia's national airworthiness authority to ensure compliance with international safety standards. These directives apply to the State of Registry of an individual aircraft, which is mandated to ensure the continuing airworthiness of aircraft registered within its jurisdiction. The application of these directives is not subject to public consultation, as they are based on international obligations and the assessments conducted by CASA in response to ADs issued by the relevant State of Design. Furthermore, these ADs are exempt from requiring a Regulatory Impact Statement, streamlining the process for maintaining aviation safety standards in Australia.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs). Section 98 of the Act empowers the Governor-General to make regulations necessary for the safety of air navigation, while regulation 39.001 of the Safety Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These directives are considered legislative instruments, subject to disallowance and review under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
The obligations imposed by these provisions on CASA and other entities are significant. CASA, as Australia's national airworthiness authority, must rigorously assess ADs issued by the State of Design when they pertain to aircraft on the Australian Register. This assessment ensures that CASA can issue its own ADs, such as the Australian AD/S-PUMA/74 in response to EASA's AD 2008-0035-E, thereby enforcing the necessary safety measures and compliance requirements for aircraft operating within Australia. The State of Registry, in this case, CASA, has the responsibility to ensure that aircraft maintain their airworthiness through the implementation of these directives.
Breaching the requirements set out in ADs can lead to serious consequences. Failure to comply with an AD can result in severe penalties, including fines and imprisonment, as the directives are integral to maintaining the safety of air navigation. The specifics of these penalties, including maximum fines and imprisonment terms, are dictated by the overarching provisions of the Civil Aviation Act 1988 and related regulations. Non-compliance not only endangers the safety of the aircraft but also poses significant risks to the broader aviation ecosystem.
