Overview

The Civil Aviation Safety Regulations 1998, as amended, provide the regulatory framework for ensuring the safety of civil aviation in Australia. Enacted under section 98 of the Civil Aviation Act 1988, these regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives to maintain the safety of aircraft and aeronautical products. A key issue these regulations address is the need for harmonised safety standards in line with the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 allow CASA to implement airworthiness directives that reflect international safety standards, ensuring that Australian aircraft meet global safety benchmarks. The policy objective is to maintain the highest possible safety standards in civil aviation by aligning Australian regulations with international best practices and ensuring that the State of Registry has the necessary information and authority to enforce continuing airworthiness requirements.

Scope and Application

The Civil Aviation Safety Regulations 1998 (CASR) and the Civil Aviation Act 1988 (Act) together establish the regulatory framework for airworthiness directives (ADs) in Australia. The Act grants the Governor-General the authority to create regulations implementing the Convention on International Civil Aviation, with a particular focus on safety. Regulation 39.001 of the CASR allows the Civil Aviation Safety Authority (CASA) to issue ADs for aircraft types or aeronautical products. This Act applies to all individuals and entities involved in the operation and maintenance of aircraft registered in Australia, as well as to the aircraft themselves and the aeronautical products they contain. The geographic scope of the Act is national, extending to all aircraft within Australia's jurisdiction, regardless of where they were manufactured or registered. However, specific ADs may target particular aircraft types or aeronautical products. The Act can be extended or restricted through subordinate instruments, such as ADs, which may apply to specific aircraft or aeronautical products. Exemptions or thresholds may be defined within these subordinate instruments, allowing CASA to grant exclusions or approve alternative compliance means. In this specific case, the repeal of Airworthiness Directive AD/JBK 117/25 for Kawasaki BK 117 series helicopters reflects the cancellation of this directive by the Japanese Civil Aviation Bureau, rendering it unnecessary for Australian application.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CASR) under section 98 of the Civil Aviation Act 1988 provide the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various kinds of aircraft or aeronautical products (section 39.001). This authority includes the power to repeal, rescind, revoke, amend, or vary such directives, as stipulated under subsection 33 (3) of the Acts Interpretation Act 1901. ADs are critical for ensuring the continuing airworthiness of aircraft, and their requirements are often issued by the State of Design under Annex 8 to the Convention on International Civil Aviation. For Australian registered aircraft, these foreign ADs apply unless CASA grants an exclusion or approves an alternative means of compliance (CASR 39.001A). The main obligation imposed by the CASR on parties governed by these regulations is the necessity to comply with ADs issued by CASA or recognised foreign authorities, such as the Japanese Civil Aviation Bureau (JCAB). This includes ensuring that specified aircraft or aeronautical products meet the inspection, rectification, or maintenance requirements outlined in the relevant ADs. CASA has the discretion to grant exclusions from an AD or approve alternative means of compliance when it deems appropriate. Failure to comply with the requirements of an AD can result in significant consequences, including potential enforcement actions by CASA. While the specific penalties for non-compliance with ADs are not detailed in the explanatory statement, violations of aviation safety regulations generally can lead to civil or criminal penalties, including fines and imprisonment. The exact penalties depend on the severity of the violation and the specific provisions of the Civil Aviation Act 1988 and other relevant legislation. This legislative instrument, CASA ADCX 005/21, repeals AD/JBK 117/25, which pertained to the Kawasaki BK 117 series helicopters. This repeal follows the JCAB’s cancellation notice TCD-6982A-2021, which rendered the AD requirements obsolete as of 13 April 2021. CASA determined that no consultation was necessary under section 17 of the Legislation Act 2003 because the AD had already been repealed by the JCAB. Additionally, no Regulation Impact Statement (RIS) was required, as ADs are covered by a standing agreement between CASA and the Office of Best Practice Regulation (OBPR id. 14507). The instrument also includes a Statement of Compatibility with Human Rights, confirming that the repeal of the AD does not engage any applicable rights or freedoms, and is thus compatible with human rights as recognised under international instruments.
