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 36/30, Amendment 1, affecting Beechcraft models 36 series aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 36/30, Amendment1. The cancellation will become effective on 08 May 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 ensure the safety of air navigation and to address gaps in regulatory frameworks that could compromise air safety. The Civil Aviation Safety Regulations 1998, made under the authority of this Act, empower 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 ensure aircraft maintain their airworthiness over time, in accordance with international standards set by the Convention on International Civil Aviation. This regulatory framework is designed to mandate safety measures and ensure that the State of Registry for an aircraft in Australia adheres to necessary airworthiness requirements. CASA, acting as Australia's national airworthiness authority, assesses information from the State of Design and, if appropriate, issues Australian ADs to enforce these requirements. The 2008 cancellation of AD/BEECH 36/30, Amendment 1, for Beechcraft models 36 series aircraft exemplifies this process, demonstrating CASA’s commitment to maintaining safe air navigation practices in alignment with international obligations.
Scope and Application
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. This authority is exercised through the Civil Aviation Safety Regulations 1998, particularly regulation 39.001, which enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are critical for maintaining the continuing airworthiness of aircraft and are considered legislative instruments under the Legislative Instruments Act 2003. In accordance with Annex 8 to the Convention on International Civil Aviation, the State of Design is primarily responsible for the continuing airworthiness of an aircraft type, and the State of Registry must adopt or develop requirements to ensure the same. Consequently, when an AD is issued by the State of Design, CASA, as Australia’s national airworthiness authority, must review and, if necessary, issue corresponding Australian ADs. The authority to issue these directives is exercised by CASA, ensuring that all aircraft on the Australian Register meet the necessary safety standards.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, allows the Governor-General to establish regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and therefore, they are legislative instruments as per section 6 of the Legislative Instruments Act 2003. ADs are a critical tool in maintaining the continuing airworthiness of aircraft types, as stipulated in Annex 8 to the Convention on International Civil Aviation, which places the responsibility for this on the State of Design.
Under these regulations, the State of Design must provide necessary information to ensure an aircraft type's continuing airworthiness, which is then assessed by the State of Registry. In Australia, CASA is the national airworthiness authority responsible for assessing information provided by the State of Design and issuing corresponding Australian ADs if necessary. For instance, regarding the Beechcraft models 36 series aircraft, CASA issued AD/BEECH 36/30, Amendment 1, which has now been cancelled. This cancellation will take effect on 8 May 2008, as the unsafe condition addressed by the AD no longer exists, thereby eliminating the need for a replacement AD.
The obligations imposed by these regulations on the parties involved include the State of Design's responsibility to issue ADs to ensure the continuing airworthiness of aircraft types, and the State of Registry's duty to assess this information and issue Australian ADs where necessary. CASA, as the State of Registry, must conduct thorough assessments to ensure that Australian ADs align with international standards and address any safety concerns effectively. Failure to comply with these obligations can result in significant safety risks and potential legal consequences.
The Civil Aviation Safety Regulations 1998 also outline the penalties for breaches of the ADs. The Act does not specify particular offences or penalties for non-compliance with ADs but implies that failure to adhere to these directives can lead to severe civil or criminal consequences. Non-compliance could potentially result in the grounding of aircraft, financial penalties, or even imprisonment, depending on the severity of the safety breach. These consequences underscore the critical importance of adhering to ADs to maintain the highest safety standards in civil aviation.
