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 Civil Aviation Safety Authority or its predecessors issued AD/BEECH 23/6 affecting Beech B23 models fitted with a nylon rudder pedal position gear. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 23/6. The cancellation will become effective on 20 December 2007. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 is the primary piece of legislation governing civil aviation in Australia, enacted to ensure the safety of air navigation and to provide a framework for the regulation of civil aviation activities within Australia. The Act grants the Governor-General the authority to make regulations that serve the interests of air navigation safety. Among these regulations are the Civil Aviation Safety Regulations 1998, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are integral to maintaining the continuing airworthiness of aircraft, ensuring that they meet the necessary safety standards. The Civil Aviation Act 1988, therefore, addresses the need for a robust regulatory framework to manage and enforce safety standards in civil aviation, aligning with international obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to section 98 of the Civil Aviation Act 1988, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments under the Legislative Instruments Act 2003, aimed at ensuring the safety of air navigation. The ADs are a reflection of Australia's commitment to international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must ensure the aircraft's ongoing compliance with airworthiness standards. CASA, as the national airworthiness authority, evaluates ADs issued by the State of Design and, if necessary, issues corresponding Australian ADs to enforce the required safety measures. In the specific case of AD/BEECH 23/6, which affected Beech B23 models with a nylon rudder pedal position gear, CASA has assessed and subsequently cancelled this directive due to the resolution of the unsafe condition, with the cancellation taking effect on 20 December 2007. This action aligns with Australia's obligations under international aviation conventions and has been executed without public consultation or the need for a Regulatory Impact Statement, as deemed by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 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 specified in section 6 of the Legislative Instruments Act 2003 and subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998. The primary purpose of these ADs is to ensure the continuing airworthiness of aircraft, aligning with the requirements of Annex 8 to the Convention on International Civil Aviation. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA must review this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This process ensures that Australian aircraft comply with international standards for airworthiness.
Under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, various obligations and requirements are imposed on CASA and other entities involved in the airworthiness of aircraft. CASA, as the national airworthiness authority, must assess and issue ADs when required, ensuring that Australian-registered aircraft meet safety standards. The State of Design has the responsibility to provide necessary information to ensure the continuing airworthiness of an aircraft type, while the State of Registry must develop or adopt requirements to ensure the airworthiness of individual aircraft. These obligations ensure that all stakeholders are accountable for maintaining the safety and airworthiness of aircraft.
The Civil Aviation Safety Regulations 1998, as well as the Civil Aviation Act 1988, outline potential consequences for non-compliance with airworthiness directives. While the specific penalties for breaching ADs are not detailed in the text, non-compliance with safety regulations generally can result in significant legal and financial repercussions. These may include fines, imprisonment, or both, depending on the severity of the breach. The exact penalties are determined by the courts and may vary based on the specific circumstances of the case.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 also address the cancellation of airworthiness directives. In the case of AD/BEECH 23/6, which affected Beech B23 models fitted with a nylon rudder pedal position gear, CASA assessed the AD and determined that it could be cancelled as the unsafe condition no longer existed. This cancellation was made in accordance with subsection 84A(2) of the Act and became effective on 20 December 2007. The cancellation of ADs such as this one demonstrates the importance of continuous assessment and improvement of safety standards in the aviation industry.
