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 German LBA has issued AD D-2005-414 affecting EC 135 model helicopters. Germany is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/EC 135/11, which will become effective on 16 February 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 govern aviation safety and other related matters in Australia, was introduced to address the need for a robust legal framework to ensure the safety of air navigation. This Act allows the Governor-General to make regulations for the purposes of the Act, particularly for maintaining the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of this Act, provide for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). The policy objective is to ensure that aircraft and aeronautical products meet the necessary safety standards, aligning with international obligations under the Convention on International Civil Aviation.
In accordance with Annex 8 of the Convention on International Civil Aviation, the State of Design has the responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry. When a State of Design issues an AD, CASA must assess and, if necessary, issue an Australian AD to mandate the requirements. This process ensures compliance with international standards and obligations, as exemplified by the issuance of Australian AD/EC 135/11 in response to a German AD, D-2005-414, for EC 135 model helicopters. Given that ADs are issued in compliance with international agreements, they do not require public consultation or a Regulatory Impact Statement.
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 specific types of aircraft or aeronautical products. These directives are legislative instruments as per section 46A of the Acts Interpretation Act 1901, and they must adhere to the Legislative Instruments Act 2003. ADs are crucial for ensuring the continuing airworthiness of aircraft and are mandated by Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for providing necessary information to the State of Registry. In Australia, CASA, as the national airworthiness authority, must assess ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs to enforce the required safety measures. For instance, in response to a German airworthiness directive affecting EC 135 model helicopters, CASA issued Australian AD/EC 135/11. Given that such directives stem from international obligations and are directly related to safety, they do not require public consultation or a Regulatory Impact Statement. The issuance of these ADs is managed by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the legal framework for the issuance and enforcement of airworthiness directives (ADs) in Australia. Section 98 of the Act allows the Governor-General to make regulations in the interest of safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and are legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. An AD is a formal means by which CASA can mandate safety requirements for specific types of aircraft to ensure their continuing airworthiness.
The obligations under these regulations require CASA to closely monitor the safety of aircraft types designed and manufactured in other countries. When the State of Design, which is the country where the aircraft type is designed, issues an AD, CASA must assess the AD and determine whether it is appropriate to issue a corresponding Australian AD. This process ensures that Australian aircraft meet the necessary safety standards as outlined by the State of Design. In the case of the German LBA issuing AD D-2005-414 for EC 135 model helicopters, CASA has assessed and issued Australian AD/EC 135/11, which will become effective on 16 February 2006. This action aligns with Australia’s obligations under the Convention on International Civil Aviation, where the State of Design bears responsibility for the continuing airworthiness of aircraft types.
Parties governed by these regulations, including aircraft manufacturers, operators, and maintenance organisations, must comply with the ADs issued by CASA. They are required to implement any mandated safety measures or modifications to their aircraft as specified in the ADs. Failure to comply with these requirements can result in serious safety risks, as well as legal consequences. Operators must ensure their aircraft meet the AD requirements before continuing operations, and maintenance organisations must perform the necessary modifications or inspections as directed by the ADs.
Violations of ADs can lead to severe penalties. Under the Civil Aviation Act 1988, non-compliance with ADs can be considered an offence, potentially resulting in criminal charges. For instance, section 40 of the Act provides for offences related to operating an aircraft in a manner that endangers safety, which can include failure to comply with an AD. The maximum penalties for these offences can include substantial fines and imprisonment, reflecting the serious nature of non-compliance with safety directives. In addition to criminal penalties, operators and maintenance organisations can face civil penalties, including fines and the potential suspension or revocation of their operating or maintenance certificates. These stringent measures are designed to enforce adherence to safety standards and ensure the highest levels of air safety.
