AD/L200/3 - Propeller De-Icing Control - Modification - CANCELLED

Overview

The Civil Aviation (Airworthiness Directives) Amendment Instrument 2009 (F2009L02278) was enacted to address the need for the Civil Aviation Safety Authority (CASA) to issue and cancel airworthiness directives in accordance with the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. The Act was passed by the Australian Parliament to ensure the safety of air navigation and to establish regulatory frameworks governing civil aviation. The Civil Aviation Safety Regulations 1998 were created under the authority of section 98 of the Civil Aviation Act 1988, which empowers the Governor-General to make regulations in the interests of the safety of air navigation. Regulation 39.001 of these regulations enables CASA to issue airworthiness directives for kinds of aircraft or aeronautical products, with such directives being considered disallowable instruments under the Acts Interpretation Act 1901. The policy objective of this legislative instrument is to uphold the safety standards of air navigation by aligning with the international obligations of the Convention on International Civil Aviation, specifically Annex 8, which places responsibility on the State of Design for the continuing airworthiness of an aircraft type and mandates the dissemination of necessary information to the States of Registry.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that mandate specific requirements for maintaining the airworthiness of certain types of aircraft and aeronautical products. These directives apply to aircraft registered in Australia and are integral to ensuring compliance with national and international safety standards. The State of Registry, in this case CASA, holds the responsibility for assessing and issuing these directives when necessary, particularly when the State of Design issues an AD for aircraft types registered in Australia. The issuance of these ADs is grounded in international obligations under Annex 8 to the Convention on International Civil Aviation, which mandates that States of Design provide necessary information to ensure the continuing airworthiness of aircraft types. ADs are thus a critical tool for maintaining safety and airworthiness standards across the aviation industry. The authority to issue these directives is granted through regulation 39.001 of the Civil Aviation Safety Regulations 1998, with any such directives being considered disallowable instruments under the Acts Interpretation Act 1901 and legislative instruments under the Legislative Instruments Act 2003. The scope of these regulations is broad, covering all aircraft and aeronautical products registered in Australia, and is enforced nationally by CASA as Australia's national airworthiness authority.

Key Provisions

The Civil Aviation Act 1988, under section 98, empowers the Governor-General to create regulations to ensure the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This legislative framework ensures that the ongoing airworthiness of aircraft is consistently monitored and maintained. Notably, under subregulation 39.001(5), ADs are classified as disallowable instruments, subject to scrutiny under section 46A of the Acts Interpretation Act 1901. Consequently, as per section 6 of the Legislative Instruments Act 2003, ADs are recognised as legislative instruments. The obligations imposed by these regulations on parties, such as aircraft manufacturers and operators, are significant. The State of Design, typically the country where the aircraft is designed, holds primary responsibility for the continuing airworthiness of the aircraft type and must provide necessary information to States of Registry to facilitate compliance with airworthiness standards. Conversely, the State of Registry, which registers the individual aircraft, must implement or adopt specific requirements to maintain the airworthiness of aircraft within its jurisdiction. CASA, acting on behalf of Australia, is mandated to evaluate information from the State of Design and, if deemed necessary, issue Australian ADs that enforce the requirements of the State of Design. In the context of the Morava L200 series aeroplanes, CASA issued AD/L200/3, which has since been assessed and subsequently cancelled by CASA. The cancellation of this AD, effective from 2 July 2009, signifies that the previously identified unsafe condition no longer exists, thereby negating the need for a replacement AD. This action aligns with Australia’s commitments under the Convention on International Civil Aviation, which underscores the necessity of such measures to uphold international safety standards. Given the nature of this regulatory action, no consultation with the Australian public was conducted, and the Office of Best Practice Regulation has confirmed that ADs do not require a Regulatory Impact Statement. Failure to comply with the requirements outlined in airworthiness directives can result in serious legal consequences. Under the Civil Aviation Act 1988, non-compliance may lead to enforcement actions by CASA, which can include the issuance of fines or other penalties. The severity of these penalties can vary, with the maximum financial penalties outlined in the Act potentially amounting to substantial sums, reflecting the critical importance of maintaining airworthiness in ensuring the safety of air travel. Civil and criminal liabilities may also ensue for individuals or entities found in breach of these regulations, further emphasising the need for strict adherence to airworthiness directives.
