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.
CASA issued AD/BEECH 200/16, affecting Beech 200 model aircraft in 1977. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 10 April 2008. No replacement AD is required, as the original unsafe condition no longer exists.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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 provide a comprehensive legal framework for the regulation of civil aviation in Australia, addressing gaps in safety, security, and efficiency within the industry. One of its key provisions is the authority granted to the Governor-General to make regulations for the safety of air navigation, as seen in the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs, which are legislative instruments subject to disallowance, are essential tools for ensuring the continuing airworthiness of aircraft, aligning with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA), as Australia's national airworthiness authority, plays a critical role in assessing and issuing these directives to mandate safety requirements derived from the State of Design. The recent cancellation of AD/BEECH 200/16, reflecting the resolution of a previously identified unsafe condition, demonstrates CASA's commitment to maintaining regulatory standards and reducing unnecessary burdens on the aviation industry.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Pursuant to section 98 of the Act, the Governor-General has the authority to enact regulations, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003. The State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry, as outlined in Annex 8 of the Convention on International Civil Aviation. CASA, acting as Australia's national airworthiness authority, assesses this information and issues Australian ADs when required. For example, CASA issued AD/BEECH 200/16 in 1977 for Beech 200 model aircraft, which has now been cancelled due to the resolution of the original unsafe condition, effective from 10 April 2008. The cancellation of this AD was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the provisions of the Act.
Key Provisions
The Civil Aviation Act 1988 (section 98) grants the Governor-General the authority to create regulations aimed at ensuring the safety of air navigation. Under this authority, 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 serve as crucial instruments for maintaining the continuing airworthiness of aircraft, as outlined in Annex 8 of the Convention on International Civil Aviation. It is important to note that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments according to section 6 of the Legislative Instruments Act 2003.
The obligations placed on parties and entities by these regulations are substantial. The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to States of Registry to ensure the safety of the aircraft. The State of Registry, in turn, must develop or adopt requirements to maintain the airworthiness of the aircraft under its jurisdiction. In Australia, CASA, as the national airworthiness authority, must evaluate information from the State of Design and issue corresponding ADs as required. This ensures that Australian aircraft meet the necessary safety standards.
Failure to comply with ADs can result in significant legal consequences. The Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 establish various offences related to non-compliance with airworthiness directives. These offences can result in both civil and criminal penalties, depending on the severity of the breach. Civil penalties may include fines and other monetary sanctions, while criminal penalties can encompass imprisonment and additional fines. The exact penalties depend on the specific provisions of the Act and Regulations, but they underscore the importance of adhering to ADs to maintain aviation safety.
In summary, the Civil Aviation Act 1988 and associated regulations place significant responsibilities on both the State of Design and the State of Registry to ensure the airworthiness of aircraft. CASA's role in issuing and enforcing ADs is crucial to maintaining these safety standards. Non-compliance with ADs can lead to serious legal consequences, highlighting the importance of adhering to these regulations.
