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 23/42 affecting Beechcraft A23, 23, C23 and A24R model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 23/42. The cancellation will become effective on 10 April 2008. 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, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. The Civil Aviation Safety Regulations 1998 were subsequently established to give effect to the Act, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. The objective of these regulations is to uphold the safety standards in line with Australia's commitments under international conventions, particularly the Convention on International Civil Aviation. The Civil Aviation Safety Regulations mandate that CASA, as the national airworthiness authority, must respond to airworthiness directives issued by the aircraft's State of Design, ensuring that any unsafe conditions identified are addressed appropriately within the Australian context. The process involves CASA assessing the information provided and, if necessary, issuing corresponding Australian ADs to enforce compliance with the identified safety requirements.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a legislative framework for ensuring the safety of air navigation in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the Act's purposes, specifically focusing on the safety of air navigation. 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, thereby mandating compliance with safety standards. These ADs serve as legislative instruments and are subject to disallowance provisions under section 46A of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The application of these directives extends to all aircraft registered in Australia, ensuring they meet continuing airworthiness standards as outlined by Annex 8 to the Convention on International Civil Aviation. The State of Registry, typically CASA, assesses and implements these directives to maintain safety standards and compliance. This regulatory mechanism ensures that aircraft meet international safety standards and that the authority to issue and enforce ADs is exercised in line with Australia's international obligations.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further specifies that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Under subregulation 39.001(5), ADs are classified as disallowable instruments, which means they are legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. These directives are a common means of ensuring the continuing airworthiness of aircraft types, as mandated by Annex 8 to the Convention on International Civil Aviation.
The Act and the associated regulations impose obligations on CASA and other entities. CASA, as Australia's national airworthiness authority, is required to assess information from the State of Design (the country where the aircraft was designed) and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. The State of Registry, which is the country where the aircraft is registered, is responsible for ensuring the continuing airworthiness of the aircraft. This means that CASA must review and, where appropriate, implement the directives issued by the State of Design for aircraft registered in Australia. The process ensures compliance with international standards and maintains the safety and airworthiness of aircraft operating in Australian airspace.
In terms of consequences for non-compliance, the regulations do not explicitly outline specific offences, penalties, or civil or criminal consequences for breaching ADs. However, non-compliance with ADs can lead to serious safety issues and may result in enforcement actions by CASA. These actions can include fines, suspension of the aircraft's certificate of airworthiness, or other regulatory penalties. The severity of these penalties can vary depending on the nature and extent of the non-compliance, but they are intended to enforce adherence to safety standards and ensure the safe operation of aircraft.
