CASA ADCX 019/10 - Revocation of Airworthiness Directives

Overview

The Civil Aviation Regulations 1988, enacted in 1988, are a fundamental piece of legislation designed to regulate civil aviation in Australia, ensuring the safety of air navigation and the continuing airworthiness of aircraft. These regulations are made under the authority of the Civil Aviation Act 1988, which empowers the Governor-General to enact regulations in the interests of safety. The Civil Aviation Safety Regulations 1998 further provide for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are legislative instruments that are subject to disallowance by Parliament, as stipulated in the Legislative Instruments Act 2003. The specific legislative instrument in question, F2010L02155, addresses the revocation of certain ADs issued by foreign authorities, such as the European Aviation Safety Agency (EASA) and the Federal Aviation Administration (FAA), and their replacement with Australian ADs. This revocation was implemented by the Manager, Continuing Airworthiness in the Airworthiness and Engineering Branch on behalf of CASA, in accordance with the Civil Aviation Act 1988. This measure was taken to ensure that Australian aviation standards remain consistent with international obligations under the Convention on International Civil Aviation and to maintain the safety and continuing airworthiness of aircraft registered in Australia.

Scope and Application

The Civil Aviation Regulations 1988, as amended by F2010L02155, apply to airworthiness directives (ADs) issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Act 1988. These regulations pertain to aircraft registered in Australia, ensuring the safety of air navigation as per the provisions of the Act. Specifically, the ADs addressed in this legislation are those issued on or after 1 October 2009, and they relate to the continuing airworthiness of aircraft types designed by foreign states, which have been superseded by directives from other national authorities such as the European Aviation Safety Agency (EASA) and the Federal Aviation Administration (FAA). This Act's reach is national, with CASA acting as the central authority responsible for evaluating and potentially mandating airworthiness directives for Australian-registered aircraft. While the Act does not explicitly state exclusions or exemptions, the focus remains on ensuring that any airworthiness directives issued maintain the highest safety standards in accordance with international conventions such as Annex 8 to the Convention on International Civil Aviation.

Key Provisions

The Civil Aviation Regulations 1988, as amended, include provisions for the revocation of airworthiness directives (ADs) under section 39.001 of the Civil Aviation Safety Regulations 1998. These regulations provide the legal framework for issuing ADs, which are legislative instruments intended to maintain or ensure the continuing airworthiness of aircraft. Specifically, section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations that serve the safety of air navigation. These regulations enable the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. The ADs issued by the State of Design or State of Registry must be assessed by CASA, which can then issue corresponding Australian ADs if necessary. The obligations under the Act for parties or entities governed by the ADs are stringent. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry, which are responsible for the individual aircraft's continuing airworthiness. CASA, as Australia’s national airworthiness authority, must evaluate this information and issue ADs as required. The revocation of certain State of Design ADs, such as AD/A320/173 and AD/B767/138 Amdt 3, indicates that these ADs have been superseded by more recent directives from other authorities, such as EASA AD 2010-0148 and FAA AD 2010-14-18. This means that operators and owners of the affected aircraft must comply with the newer directives rather than the revoked ones. Non-compliance with the ADs can lead to significant legal consequences. The Civil Aviation Regulations 1988, in conjunction with the Civil Aviation Act 1988, establish a framework where failure to adhere to airworthiness directives can result in both civil and criminal penalties. Civil penalties may include fines, while criminal penalties could involve imprisonment. The exact penalties depend on the specific breach and the discretion of the courts. Furthermore, operating an aircraft that does not comply with applicable ADs can result in severe safety risks, leading to potential grounding of the aircraft and further enforcement actions by CASA.
