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 55/37 Amendment 1 affecting Beechcraft 95-C55, 95-C55A, D55, D55A, E55 and E55A model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 55/37 Amendment 1. The cancellation will become effective on 5 June 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 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, enacted by the Parliament of Australia, was introduced to establish a framework for the regulation of civil aviation, ensuring safety and efficiency in air navigation. Section 98 of this Act empowers the Governor-General to make regulations for the safety of air navigation, while the Civil Aviation Safety Regulations 1998 provide further detail, including the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance and regulation under the Legislative Instruments Act 2003. The Civil Aviation Act 1988 and its accompanying regulations are designed to align with international standards, particularly those set by the International Civil Aviation Organization (ICAO), to maintain the safety and airworthiness of aircraft both domestically and globally.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, authorise the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft and aeronautical products within Australia. This Act applies to the State of Registry of an individual aircraft, which is responsible for ensuring the continuing airworthiness of aircraft registered in Australia. The ADs are legislative instruments that must be assessed by CASA when issued by the State of Design. This particular AD/BEECH 55/37 Amendment 1, affecting specific models of Beechcraft aircraft, has been cancelled by CASA as the unsafe condition it addressed no longer exists. The cancellation of this AD is a result of Australia's obligations under the Convention on International Civil Aviation, and no public consultation or Regulatory Impact Statement was required. The AD was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, provide the framework for the issuance and management of airworthiness directives (ADs) in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to create regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. It is important to note that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are treated as legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are significant for both CASA and aircraft operators. CASA, as Australia’s national airworthiness authority, is responsible for assessing any ADs issued by the State of Design and determining if an Australian AD is necessary to ensure the continuing airworthiness of aircraft registered in Australia. This includes reviewing the AD and ensuring that it aligns with international standards set forth by the Convention on International Civil Aviation. Aircraft operators, on the other hand, are required to comply with any ADs that are applicable to their aircraft. This compliance is critical to maintaining the safety and airworthiness of the aircraft, ensuring that any identified unsafe conditions are addressed promptly and effectively.
Failure to comply with ADs can result in serious consequences, both civil and criminal. Under section 42 of the Civil Aviation Act 1988, a person who contravenes an AD can be liable for a civil penalty. The maximum penalty for such an offence can be significant, reflecting the gravity of failing to adhere to safety regulations designed to protect the public. Additionally, in cases where non-compliance with an AD results in a serious aviation incident, criminal charges may be pursued. The potential penalties for such criminal offences can include substantial fines and imprisonment, underscoring the importance of strict adherence to ADs by all parties involved.
In summary, the Civil Aviation Act 1988 and its regulations establish a comprehensive framework for the issuance and enforcement of ADs, which are essential for maintaining the safety and airworthiness of aircraft. CASA is tasked with the responsibility of issuing and enforcing these directives, while aircraft operators must comply with all relevant ADs to ensure their aircraft remain safe and airworthy. Non-compliance can lead to severe civil and criminal penalties, highlighting the critical importance of adhering to these safety regulations.
