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/CESSNA 337/7 affecting Cessna 337 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 337/7. The cancellation will become effective on 8 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 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 Commonwealth Parliament, serves to regulate and ensure the safety and efficiency of civil aviation within Australia. This legislation empowers the Governor-General to make regulations that align with the Act's objectives, particularly focusing on the safety of air navigation. One such regulation is the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are intended to maintain and ensure the continuing airworthiness of aircraft in accordance with international standards set by the International Civil Aviation Organization (ICAO). In this context, CASA's role as Australia’s national airworthiness authority involves assessing and, if necessary, issuing ADs to comply with the requirements set by the aircraft’s State of Design, ensuring the safety standards are uniformly upheld across the Australian Register. The cancellation of certain ADs, such as the AD/CESSNA 337/7 affecting Cessna 337 aircraft, reflects the dynamic nature of airworthiness directives and the continuous efforts to address and resolve safety concerns in alignment with international obligations.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) aimed at ensuring the safety of air navigation. These regulations apply to any kind of aircraft or aeronautical product within Australia, requiring the State of Registry to implement measures ensuring the continuing airworthiness of such aircraft. This includes the assessment and enforcement of ADs issued by the State of Design. In this specific case, CASA has cancelled Australian AD/CESSNA 337/7 for Cessna 337 aircraft, effective 8 May 2008, due to the cessation of the unsafe condition that initially necessitated the directive. The cancellation aligns with Australia's commitments under the Convention on International Civil Aviation, and no replacement AD is required. The AD cancellation process did not involve public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation. The AD was issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the relevant provisions of the Act.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, specifically section 98, empower the Governor-General to make regulations in the interest of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that ADs are disallowable instruments under the Acts Interpretation Act 1901 and, therefore, constitute legislative instruments under the Legislative Instruments Act 2003. These ADs play a critical role in maintaining the continuing airworthiness of aircraft, as outlined under Annex 8 to the Convention on International Civil Aviation.
Under this legislation, CASA has certain obligations and requirements. The State of Design, which is the country where the aircraft type is designed, holds the primary responsibility for the continuing airworthiness of the aircraft type and must provide necessary information to States of Registry to ensure this airworthiness. The State of Registry, such as Australia, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. When a State of Design issues an AD, CASA must assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that the safety standards set by the State of Design are adhered to in Australia.
In terms of legal consequences, non-compliance with the ADs issued by CASA can lead to various penalties. Although the specific civil or criminal penalties for breaching ADs are not detailed in the provided text, it is clear that failure to comply with these directives could have serious repercussions. ADs are integral to maintaining the safety and airworthiness of aircraft, and any breach of these directives could potentially result in safety hazards, leading to severe civil or criminal penalties as prescribed by relevant aviation laws.
The cancellation of AD/CESSNA 337/7, which affected Cessna 337 aircraft, exemplifies the process and rationale behind such actions. CASA assessed the AD and determined that the unsafe condition no longer existed, leading to the cancellation of the Australian AD. This cancellation became effective on 8 May 2008, and no replacement AD was necessary. Given that this cancellation was made in line with Australia’s obligations under the Convention on International Civil Aviation, no public consultation or Regulatory Impact Statement was required. The AD was issued 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, ensuring that the process adhered to the necessary legal frameworks.
