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. 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’s predecessor issued AD/PA-31/102 Amendment 2 affecting Piper PA-31T model aircraft in 1982. CASA has decided to amend this AD to improve its clarity. Amendment 3 of this AD will become effective on 31 July 2008. Amendment 3 cancels and replaces Amendment 2.
No consultation with the Australian public has taken place on this AD amendment because the amendment imposes no increase in 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, 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 was enacted to provide a comprehensive legal framework governing civil aviation in Australia, focusing on ensuring the safety and efficiency of air navigation. This legislation empowers the Governor-General to make regulations that serve the interests of aviation safety, including the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. ADs are legislative instruments designed to maintain the continuing airworthiness of aircraft and aeronautical products, ensuring compliance with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Authority (CASA) acts as the national airworthiness authority, responsible for assessing and issuing ADs for aircraft registered in Australia. The recent amendment to AD/PA-31/102 Amendment 2, effective from 31 July 2008, was undertaken by CASA to enhance clarity without increasing regulatory burdens, thus not requiring public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) playing a pivotal role in ensuring the safety of air navigation. Under this legislation, CASA is empowered to issue ADs for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments, as defined in the Legislative Instruments Act 2003, and serve as a critical means of ensuring the continuing airworthiness of aircraft, in line with the obligations under Annex 8 to the Convention on International Civil Aviation. The ADs are issued by CASA to mandate requirements for aircraft on the Australian Register, aligning with the directives issued by the aircraft's State of Design. This regulatory framework applies to all aircraft registered in Australia, ensuring a uniform approach to airworthiness across the industry. Notably, this amendment to AD/PA-31/102 Amendment 2, affecting Piper PA-31T model aircraft, was made to enhance clarity without increasing regulatory burden, and no public consultation or Regulatory Impact Statement was deemed necessary.
Key Provisions
The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) together establish the framework through which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). Section 39.001(5) of the Regulations specifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and hence qualifies as a legislative instrument under the Legislative Instruments Act 2003. The purpose of these ADs is to ensure the continuing airworthiness of aircraft and aeronautical products, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design has overarching responsibility for the airworthiness of an aircraft type, while the State of Registry, which in Australia is CASA, is responsible for ensuring the continuing airworthiness of individual aircraft.
The obligations under this legislation mandate that when an AD is issued by a State of Design against a type of aircraft registered in Australia, CASA must assess this information. If deemed necessary, CASA can issue an Australian AD to enforce the requirements of the State of Design. This ensures that all aircraft registered in Australia comply with international airworthiness standards. The State of Registry, CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft, which includes reviewing and implementing ADs issued by other States of Design. This ongoing process involves assessing the safety implications of any identified issues with aircraft types and ensuring that appropriate corrective actions are mandated.
Failure to comply with the airworthiness directives issued by CASA can lead to significant consequences. While the specific offences, penalties, or civil/criminal consequences are not detailed in the provided text, it is known that non-compliance with airworthiness regulations can result in severe penalties, including fines and potential criminal charges. These measures are in place to ensure the highest standards of aviation safety and to protect the public from the risks associated with non-compliant aircraft. The regulations underscore the importance of adhering to ADs to maintain the safety and airworthiness of aircraft operating in Australian airspace.
