Civil Aviation Regulations 1988

 

Revocation of Airworthiness Directives

 

Legislation

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.

State of Design ADs issued on or after 1 October 2009 are defined as ADs per Civil Aviation Safety Regulations Part 39.001A.

Consultation

No consultation with the Australian public has taken place on these AD cancellations.  The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.

 

The AD has been made by the A/Manager, Continuing Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94 (1) of the Act.

Overview

The Civil Aviation Regulations 1988, enacted in 1988, were established to regulate civil aviation in Australia, focusing on ensuring the safety of air navigation and the continuing airworthiness of aircraft. The revocation of certain airworthiness directives (ADs) as outlined in F2011L00838 was introduced to streamline and update the regulatory framework, addressing the need for more current and relevant safety measures. This legislative instrument was made by the Civil Aviation Safety Authority (CASA), Australia’s national airworthiness authority, under section 98 of the Civil Aviation Act 1988, with the policy objective of ensuring that the continuing airworthiness of aircraft registered in Australia is maintained at the highest safety standards. The revocation of these specific ADs was intended to reflect the most recent international standards and practices, thereby enhancing the overall safety and efficiency of civil aviation in Australia.

Scope and Application

The Civil Aviation Regulations 1988, particularly as they pertain to the revocation of airworthiness directives, apply to the national airworthiness authority, the Civil Aviation Safety Authority (CASA), and all entities involved in the maintenance, operation, and registration of aircraft within Australia. These regulations are underpinned by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, and they serve to ensure the continuing airworthiness of aircraft registered in Australia. The scope of these regulations is national, extending to all aircraft operating under Australian registration, irrespective of whether they are manufactured domestically or abroad. Airworthiness directives (ADs), which are legislative instruments, are issued by CASA to mandate safety standards and rectify any identified safety deficiencies in aircraft types registered in Australia. The revocation of certain ADs, as detailed in the explanatory statement, occurs when newer or more comprehensive ADs are issued, rendering the older directives obsolete. There are no stated exclusions or exemptions in the revocation of these ADs, but it is noted that consultation with the public was not required for these specific cancellations. The application of these regulations can be extended or restricted through subordinate instruments, which allows CASA to adapt to evolving aviation safety standards and practices.

Key Provisions

The key provisions of the Civil Aviation Regulations 1988, specifically focusing on the revocation of certain airworthiness directives (ADs), are detailed in section 98 of the Civil Aviation Act 1988. This section empowers the Governor-General to establish regulations aimed at enhancing air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. As noted in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, an AD is classified as a disallowable instrument under section 46A of the Acts Interpretation Act 1901, thereby making it a legislative instrument according to section 6 of the Legislative Instruments Act 2003. The legislative intent is to ensure that airworthiness directives align with international standards and practices, as outlined in Annex 8 to the Convention on International Civil Aviation. The obligations and requirements imposed by these regulations include the responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type and to provide necessary information to the appropriate States of Registry. The State of Registry, on the other hand, must develop or adopt requirements to maintain the airworthiness of the aircraft under its jurisdiction. When a State of Design issues an AD affecting a type of aircraft on the Australian Register, CASA, as the national airworthiness authority, must evaluate this information and, if deemed necessary, issue an Australian AD to enforce the requirements set by the State of Design. This systematic approach ensures that all ADs are consistent with the overarching goal of maintaining high safety standards in civil aviation. Failure to comply with these airworthiness directives can lead to various civil and criminal consequences. Specifically, section 94 of the Civil Aviation Act 1988 stipulates that CASA can take action against entities or individuals who do not adhere to the mandated airworthiness requirements. The consequences can include fines, imprisonment, or both, depending on the severity of the non-compliance. The exact penalties are determined by the courts based on the specific circumstances of each case, but they can be significant, reflecting the critical importance of air safety. These measures underscore the legislative commitment to enforcing stringent safety standards within the aviation sector.
