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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/PA-31/43 affecting Piper PA-31-325 and PA‑31-350 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 31 July 2008. No replacement AD is required.
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, provides a legislative framework aimed at ensuring the safety of air navigation. As part of this framework, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to maintain the safety of aircraft and aeronautical products. These ADs serve as a key mechanism for enforcing continuing airworthiness as stipulated under Annex 8 of the Convention on International Civil Aviation. The Act was introduced to fill the need for comprehensive regulations governing civil aviation safety, thereby ensuring that aircraft operations within Australian airspace meet stringent safety standards. The legislative process allows CASA to issue, review, and, if necessary, cancel ADs, reflecting the dynamic nature of aviation safety requirements and the global standards set by ICAO. The legislative instrument concerning the cancellation of a specific AD, issued on behalf of CASA, is a direct application of these regulatory powers to address specific safety concerns in alignment with international obligations.
Scope and Application
The Civil Aviation Safety Regulations 1998, made under section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products, with the overarching aim of ensuring the safety of air navigation. The ADs are legislative instruments subject to disallowance, as stipulated by subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 and section 46A of the Acts Interpretation Act 1901. This legislative framework ensures that ADs align with the broader safety mandates under Annex 8 of the Convention on International Civil Aviation, where the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is tasked with ensuring the ongoing airworthiness of individual aircraft. The ADs are thus integral tools for maintaining airworthiness standards, and their issuance or cancellation is reflective of Australia’s commitment to international aviation safety norms. In this specific instance, CASA issued and subsequently cancelled AD/PA-31/43 affecting certain Piper PA-31-325 and PA-31-350 aircraft, a decision made in accordance with Australia's obligations under the Convention on International Civil Aviation and without the necessity for public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations for the safety of air navigation, and these regulations can be enforced by the Civil Aviation Safety Authority (CASA). Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows CASA to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD is a legislative instrument, as per subregulation 39.001(5) of the Regulations and section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these legislative instruments centre on ensuring the continuing airworthiness of aircraft. The State of Design, as per Annex 8 of the Convention on International Civil Aviation, bears the primary responsibility for the continuing airworthiness of an aircraft type. This includes providing necessary information to States of Registry to maintain the airworthiness of the aircraft. The State of Registry, on the other hand, is tasked with developing or adopting requirements to ensure the continuing airworthiness of individual aircraft registered within its jurisdiction. In the case of Australia, CASA, as the regulatory body, issues ADs to enforce these obligations. An example of this is AD/PA-31/43, which was issued to address specific issues with Piper PA-31-325 and PA-31-350 aircraft. CASA has since reviewed and cancelled this AD, effective from 31 July 2008, without the need for a replacement AD.
The consequences of breaching these obligations are significant. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly state penalties for non-compliance with ADs. However, failure to comply with ADs can lead to severe civil and criminal penalties, as ADs are enforceable under the Act. Infractions can result in fines, imprisonment, or both, depending on the severity of the breach. The exact penalties can vary based on the specific circumstances of the case, but the overarching goal is to ensure that all parties adhere to the stringent safety standards set forth in the legislation.
The process for issuing and cancelling ADs in Australia is rigorous and follows international standards. ADs are issued by CASA or its predecessors, such as the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, in accordance with the Act. The cancellation of ADs, such as the case with AD/PA-31/43, is also done in line with the legislative framework and Australia’s international obligations under the Convention on International Civil Aviation. This ensures that any changes to airworthiness directives are made transparently and in compliance with both domestic and international standards.
