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 US FAA has issued AD 2009-13-06 affecting Piper PA-31 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/PA-31/131, which will become effective on 27 August 2009.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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 Initial Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a comprehensive framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. This Act provides the authority for the Civil Aviation Safety Regulations 1998, which includes provisions for issuing airworthiness directives (ADs). These directives are legislative instruments designed to mandate requirements for the continuing airworthiness of aircraft and aeronautical products, ensuring they meet safety standards. The Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue such directives, which are informed by international standards and obligations under the Convention on International Civil Aviation. The process for issuing ADs is driven by the need to comply with international agreements and to maintain the safety of aircraft registered in Australia, often in response to directives issued by the State of Design. Given the nature of these directives, they are typically issued without public consultation, as they are based on international obligations and assessments by CASA.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, specifically under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, in accordance with the overarching Civil Aviation Act 1988. These directives, being legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, serve as a critical mechanism for ensuring the continuing airworthiness of aircraft types within Australia's jurisdiction. This process aligns with international obligations under Annex 8 to the Convention on International Civil Aviation, which designates the State of Design with primary responsibility for continuing airworthiness and requires them to provide necessary information to the States of Registry. In this context, CASA, as Australia's national airworthiness authority, must review ADs issued by the State of Design, such as the United States Federal Aviation Administration's AD 2009-13-06 concerning Piper PA-31 model aircraft, and issue corresponding Australian ADs as necessary. Such directives are pivotal in maintaining safety standards and compliance with international aviation protocols, with the issuance of these directives typically not necessitating public consultation or a Regulatory Impact Statement due to their regulatory nature and alignment with international obligations.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation through various regulatory mechanisms, including the issuance of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General is empowered to create regulations that serve the interests of aviation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. An AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and is classified as a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003.
These airworthiness directives are critical for maintaining the continuing airworthiness of aircraft, a responsibility that ultimately lies with the State of Registry of an individual aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, such as the United States Federal Aviation Administration (FAA) in the case of the Piper PA-31 model aircraft, has the primary responsibility for ensuring the ongoing airworthiness of an aircraft type. CASA, as Australia’s national airworthiness authority, must evaluate ADs issued by the State of Design and, if deemed appropriate, issue corresponding Australian ADs to enforce the requirements. This ensures that aircraft registered in Australia comply with international safety standards.
Compliance with ADs is mandatory for the entities and individuals governed by the Act. Aircraft operators and owners must adhere to the requirements outlined in the ADs issued by CASA, ensuring that their aircraft meet the specified safety standards. This includes conducting necessary inspections, repairs, and modifications as stipulated in the ADs. Failure to comply with these directives can result in severe consequences, including potential grounding of the aircraft and legal penalties. CASA has the authority to enforce compliance through various means, including inspections and audits.
Violating the requirements set forth in the airworthiness directives can lead to significant legal consequences. Under the Civil Aviation Act 1988, non-compliance may result in administrative penalties, such as fines. In more severe cases, criminal charges can be brought against individuals or entities responsible for the non-compliance, potentially leading to imprisonment. The exact penalties depend on the nature and severity of the breach but can be substantial, reflecting the critical importance of adhering to safety regulations in the aviation industry.
