CASA ADCX 013/10 - Revocation of Airworthiness Directives

Overview

The Civil Aviation Regulations 1988, enacted to address the need for stringent safety regulations in air navigation, provide the framework under which airworthiness directives (ADs) are issued by the Civil Aviation Safety Authority (CASA). These regulations were designed to ensure the continuing airworthiness of aircraft, in line with international standards set forth by the Convention on International Civil Aviation. The problem these regulations aimed to address was the need for a consistent and internationally recognised system to manage the safety and compliance of aircraft, particularly concerning the dissemination of critical safety information. The policy objective was to align Australia’s regulatory approach with international standards, ensuring that aircraft registered in Australia met the necessary safety requirements. The revocation of certain ADs, as specified in the Civil Aviation Regulations 1988, reflects a response to updated or superseded international directives, ensuring that Australian regulations remain current and effective.

Scope and Application

The Civil Aviation Regulations 1988, specifically under section 98 of the Civil Aviation Act 1988, provide the legislative basis for the revocation of airworthiness directives (ADs) as a means of ensuring the safety of air navigation. This Act applies to the continuing airworthiness of aircraft types and individual aircraft registered in Australia. Airworthiness directives, which are legislative instruments as per the Acts Interpretation Act 1901, are issued by the Civil Aviation Safety Authority (CASA) in response to directives from the State of Design of the aircraft. In accordance with Annex 8 of the Convention on International Civil Aviation, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, must ensure the ongoing airworthiness of individual aircraft. The regulations specifically target ADs issued on or after 1 October 2009, which are defined under CASR Part 39.001A. The revocation of these ADs occurs when they have been superseded by newer directives from the State of Design or other regulatory authorities such as the Brazilian Aeronautical Authorities and the European Aviation Safety Agency. It is noteworthy that these AD revocations were made without public consultation and do not require a Regulatory Impact Statement as determined by the Office of Best Practice Regulation.

Key Provisions

The Civil Aviation Regulations 1988, as amended by this legislation, primarily focus on the revocation of certain airworthiness directives (ADs) issued by the Civil Aviation Safety Authority (CASA) under section 98 of the Civil Aviation Act 1988 (section 3). These ADs are legislative instruments, as stated in section 39.001(5) of the Civil Aviation Safety Regulations 1998, and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The ADs being revoked are those that pertain to specific aircraft types and aeronautical products, such as the ERJ-190/23, ERJ-190/15 Amendment 2, GBK 117/25 Amendment 1, and J4100/5 Amendment 2, which have been superseded by more recent directives from other national airworthiness authorities (section 3). The obligations under this legislation require CASA to assess and respond to the issuance of ADs by the State of Design, ensuring that Australian aircraft continue to meet international airworthiness standards. CASA must evaluate any new ADs and, where necessary, issue corresponding Australian ADs to maintain compliance with safety regulations (section 3). The State of Design has the overarching responsibility for ensuring the continuing airworthiness of aircraft types, while the State of Registry must adopt or develop requirements to ensure the airworthiness of individual aircraft registered within its jurisdiction (section 3). This interplay between State of Design and State of Registry obligations is crucial for maintaining the safety and airworthiness of aircraft worldwide, and this legislation facilitates the revocation of outdated ADs in line with updated international standards. There are no explicit offences, penalties, or civil/criminal consequences outlined in this particular legislation concerning the revocation of ADs. The revocation of ADs under this Act is an administrative action taken to ensure that CASA issues the most current and relevant safety directives. However, the overarching Civil Aviation Act 1988 does provide for various enforcement mechanisms, including fines and imprisonment for breaches of safety regulations. For example, under section 22 of the Civil Aviation Act 1988, individuals or entities that fail to comply with ADs may face penalties, including fines up to $52,500 for individuals and $262,500 for corporations, as well as potential imprisonment terms. These potential penalties underscore the importance of adhering to airworthiness directives to maintain aviation safety standards.
