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 76/6, affecting Beech 76 model aircraft in 1979. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 3 July 2008. No replacement AD is required, as all affected aircraft would have been inspected, and, if necessary, modified long ago.
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, enacted by the Commonwealth Parliament, was established to regulate civil aviation in Australia and ensure the safety and efficiency of air navigation. One of the key issues it addresses is the ongoing airworthiness of aircraft, ensuring they meet safety standards throughout their operational life. Complementing this, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that mandate specific maintenance and operational requirements for certain types of aircraft or aeronautical products. These ADs are essential for maintaining the high safety standards set forth by international agreements, particularly Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and State of Registry. The regulatory process ensures that CASA, as Australia's national airworthiness authority, can issue ADs that reflect international standards and mitigate safety risks.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish the framework within which airworthiness directives (ADs) are issued to ensure the safety of aircraft in Australia. Under section 98 of the Act, the Governor-General can make regulations that pertain to air navigation safety, with regulation 39.001 specifically empowering the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs are considered legislative instruments as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are essential for ensuring the continuing airworthiness of aircraft, a responsibility that rests with the State of Design and the State of Registry under Annex 8 of the Convention on International Civil Aviation. CASA, acting as Australia's national airworthiness authority, must evaluate ADs issued by other states and, if necessary, issue corresponding Australian ADs. The legislative process for issuing and cancelling ADs, such as the recent cancellation of AD/BEECH 76/6 affecting Beech 76 model aircraft, is conducted by CASA's Airframes Manager in the Airworthiness Engineering Branch, in accordance with the Civil Aviation Act 1988. The cancellation of ADs, such as in this case, does not require public consultation or a Regulatory Impact Statement, as it results in a reduction of regulatory burden.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs, detailed in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, legislative instruments as per section 6 of the Legislative Instruments Act 2003. These directives are crucial in ensuring the continuing airworthiness of aircraft types, aligning with Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for such airworthiness. In Australia, CASA, acting as the national airworthiness authority, must evaluate any ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs to enforce the required maintenance and operational standards.
Entities and individuals governed by these regulations must comply with the ADs issued by CASA. This includes ensuring that all Beech 76 model aircraft, or any other aircraft types affected by ADs, are inspected, maintained, and modified as specified in the directives. The State of Registry, responsible for the continuing airworthiness of individual aircraft, must implement and enforce these requirements. Non-compliance with ADs can lead to serious safety hazards and legal consequences, as these directives are designed to address potential safety issues identified in specific aircraft types.
Failure to comply with an airworthiness directive can result in significant legal and safety repercussions. Under the Civil Aviation Act 1988, non-compliance with an AD can be considered a breach of airworthiness requirements, leading to potential enforcement actions by CASA. Such actions might include grounding of the aircraft, fines, and in severe cases, criminal charges against the operator or individual responsible for the non-compliance. The specific penalties are not detailed in the provided text, but typically, the severity of the penalty aligns with the level of risk posed by the non-compliance. Additionally, non-compliance can also result in civil liabilities, including compensation for any damages or injuries caused by the non-compliance.
In the specific case of AD/BEECH 76/6, CASA has decided to cancel this AD, effective from 3 July 2008. This decision was made after reviewing the directive and determining that all affected aircraft would have already been inspected and modified as required. No replacement AD is necessary as all necessary actions have already been completed. The cancellation aims to reduce the regulatory burden without compromising safety, and it has been determined that no Regulatory Impact Statement or public consultation is required. This decision was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
