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 USA FAA has issued AD 69-12-06 affecting Boeing 737-100, 737-200 and 737-200C aircraft. USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/280, which will become effective on 13 April 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, enacted to establish a legislative framework for the safety, efficiency, and orderly growth of civil aviation in Australia, addresses the need to regulate air navigation and safety. Under the authority of this Act, the Civil Aviation Safety Regulations 1998 were subsequently introduced, enabling the issuance of airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft. These regulations empower the Civil Aviation Safety Authority (CASA) to mandate requirements for aircraft on the Australian Register, in alignment with the obligations under the Convention on International Civil Aviation. This legislative mechanism ensures that Australia meets its international commitments while maintaining stringent safety standards domestically. The ADs are legislative instruments issued in accordance with section 6 of the Legislative Instruments Act 2003 and are designed to safeguard the safety of air navigation, reflecting the policy objective of the Act.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products, thereby ensuring the ongoing safety and airworthiness of these items. These ADs are legislative instruments as per the Legislative Instruments Act 2003. The scope of the ADs extends to mandating specific safety requirements on aircraft registered in Australia in response to directives issued by the aircraft's State of Design, which is the country responsible for the design of the aircraft type. In this context, CASA acts in accordance with its obligations under the Convention on International Civil Aviation, particularly Annex 8, which outlines the responsibilities of the State of Design and State of Registry in ensuring the continuing airworthiness of aircraft. The ADs are issued without the need for public consultation or a Regulatory Impact Statement, given their technical nature and the reliance on international safety standards. This legislative framework ensures that Australian aviation remains compliant with international safety protocols while maintaining the highest standards of airworthiness within its jurisdiction.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for ensuring the safety of air navigation in Australia, with a particular focus on the continuing airworthiness of aircraft. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations in the interests of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments that can be disallowed under section 46A of the Acts Interpretation Act 1901.
Under these provisions, CASA, as Australia’s national airworthiness authority, is tasked with ensuring that aircraft registered in Australia are maintained in an airworthy condition. When a State of Design, such as the United States in the case of the Boeing 737-100, 737-200, and 737-200C aircraft, issues an AD, CASA must assess the information and, if necessary, issue a corresponding Australian AD to mandate the requirements for Australian-registered aircraft. This was the case with the AD issued by the USA Federal Aviation Administration (FAA) as AD 69-12-06, which CASA adopted as Australian AD/B737/280, effective from 13 April 2006. These directives are critical in ensuring compliance with international standards as stipulated in Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and the State of Registry.
Entities and individuals governed by these regulations have several obligations to ensure compliance with airworthiness directives. Firstly, aircraft operators must be aware of all applicable ADs and implement the required actions within the specified timeframes. This includes conducting inspections, making necessary repairs, or grounding the aircraft if required. Manufacturers and maintenance organisations must also ensure that they are up to date with the latest ADs and that their practices align with the mandated requirements. Failure to comply with an AD can result in serious safety risks and legal consequences, as the ADs are integral to maintaining the airworthiness of the aircraft.
The Civil Aviation Safety Regulations 1998 also outline the consequences for non-compliance with airworthiness directives. While the specific penalties for breaching ADs are not detailed within the text, general provisions under the Civil Aviation Act 1988 and other related regulations typically include significant fines and potential criminal charges. The severity of penalties reflects the critical importance of adhering to ADs in maintaining the safety of air navigation. Non-compliance can lead to prosecution, with potential maximum penalties for individuals and corporations, reinforcing the necessity for strict adherence to these safety mandates.
