CIVIL AVIATION ACT 1988
CIVIL AVIATION 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. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901.
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 UK CAA has issued AD G-2004-0032 affecting Shorts SD3-60 aircraft. UK is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/SD3-60/68, which will become effective on 12 January 2005.
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 Acting Section Head – Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, was established to regulate civil aviation activities within Australia and ensure safety and efficiency in air navigation. This Act empowers the Governor-General to create regulations that serve the interests of air navigation safety, as demonstrated by the issuance of airworthiness directives under section 98. The Civil Aviation Safety Regulations 1998, made under the Act, further detail the processes and requirements for maintaining airworthiness, including the ability of the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products. These directives are essential for maintaining the continuing airworthiness of aircraft types and individual aircraft, aligning with international standards set by the International Civil Aviation Organization. The policy objective behind these provisions is to ensure that Australian aviation standards remain consistent with international safety protocols and effectively address any identified safety issues.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Regulations 1998, provides the legislative framework within which the Civil Aviation Safety Authority (CASA) operates. Under section 98 of the Act, the Governor-General is empowered to issue regulations that align with the Act's objectives, particularly focusing on the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises CASA to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs serve as a crucial mechanism for ensuring the continuing airworthiness of aircraft, aligning with international obligations under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has overall responsibility for an aircraft type's airworthiness. In practice, CASA, as Australia's national airworthiness authority, must assess and, where necessary, issue Australian ADs in response to directives from the State of Design, such as the recent AD issued by the UK Civil Aviation Authority affecting Shorts SD3-60 aircraft. This AD, which CASA has assessed and will implement as Australian AD/SD3-60/68 effective from 12 January 2005, does not require public consultation due to its alignment with international civil aviation conventions. The AD was made by the Acting Section Head – Airframes, Airworthiness Standards Branch, Standards Division, in accordance with subsection 84A(2) of the Act, highlighting the regulatory process underpinning the safe operation of aircraft in Australian airspace.
Key Provisions
The Civil Aviation Act 1988, particularly under section 98, empowers the Governor-General to create regulations that enhance the safety of air navigation. This includes the ability to issue airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998, as outlined in regulation 39.001. ADs are crucial instruments that provide detailed instructions to ensure the continued safety and airworthiness of specific aircraft types or aeronautical products. These directives are not subject to disallowance under section 46A of the Acts Interpretation Act 1901, ensuring their legal enforceability.
The obligations imposed by these provisions primarily rest on the Civil Aviation Safety Authority (CASA) as the national airworthiness authority. CASA must meticulously assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to ensure compliance with international standards. This includes taking into account the responsibilities of the State of Design, as outlined in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type. Furthermore, the State of Registry, in this case CASA, must ensure that all aircraft registered within Australia meet the required airworthiness standards.
Breaches of the requirements set out in ADs can have serious consequences. While the specific civil or criminal penalties are not explicitly detailed in the provided text, violations of airworthiness regulations typically result in severe penalties. This could include fines, imprisonment, or both, depending on the severity and intent of the violation. The exact penalties would be governed by the broader provisions of the Civil Aviation Act 1988 and related regulations, which might impose maximum fines and imprisonment terms for non-compliance with airworthiness directives. These consequences underscore the critical importance of adhering to ADs to maintain the highest safety standards in air navigation.
