AD/S-76/41 - Emergency Flotation System - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to establish a legal framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the industry. This Act empowers the Governor-General to make regulations necessary for the safety of air navigation, with the Civil Aviation Safety Regulations 1998 further detailing these provisions. One such regulation, under section 39.001, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, making them legislative instruments subject to disallowance. These directives are crucial for maintaining the continuing airworthiness of aircraft and align with international standards set forth in Annex 8 of the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 also outline that ADs are a common form of continuing airworthiness information issued by ICAO Contracting States. CASA, as Australia's national airworthiness authority, has the responsibility to assess and, if necessary, issue Australian ADs when corresponding directives are issued by the State of Design.

Scope and Application

The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. These ADs apply to specific types of aircraft or aeronautical products, and CASA, acting as Australia’s national airworthiness authority, must comply with international obligations under the Convention on International Civil Aviation. Specifically, the State of Design has overall responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, must ensure the aircraft's ongoing compliance with airworthiness standards. The issuance of ADs is a legislative instrument under the Legislative Instruments Act 2003, and these directives are crucial for maintaining safety standards across the aviation industry. The geographic reach of these regulations is national, ensuring uniform safety standards are maintained across Australia. The application of ADs can be extended or restricted through subordinate instruments, and while ADs are typically issued to address specific safety concerns, they do not generally require public consultation or a Regulatory Impact Statement. The scope of the ADs, therefore, is comprehensive, covering all aircraft types registered in Australia and ensuring adherence to both national and international aviation safety standards.

Key Provisions

The Civil Aviation Act 1988 provides the legislative framework for the regulation of civil aviation in Australia. Section 98 of this Act empowers the Governor-General to create regulations that enhance the safety of air navigation. In particular, regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are instrumental in maintaining and ensuring the ongoing airworthiness of aircraft, thereby promoting safety in aviation. Under subregulation 39.001(5), ADs are recognised as disallowable instruments, and hence, they are considered legislative instruments as per section 6 of the Legislative Instruments Act 2003. An AD serves as a formal instruction issued by a national aviation authority to ensure that aircraft remain airworthy. According to Annex 8 to the Convention on International Civil Aviation, the State of Design, which is responsible for the initial design of the aircraft, holds the primary responsibility for the ongoing airworthiness of the aircraft type. This responsibility includes providing any necessary information to the States of Registry to ensure the continued airworthiness of the aircraft type. In Australia, CASA, as the national airworthiness authority, must assess the information provided by the State of Design and, if appropriate, issue an Australian AD to mandate the necessary requirements. Additionally, the State of Registry, which is the country where the aircraft is registered, is responsible for the continuing airworthiness of the individual aircraft. This involves developing or adopting requirements to ensure the aircraft remains airworthy. CASA has issued AD/S-76/41 concerning Sikorsky S-76 series helicopters, but has subsequently cancelled this directive. The cancellation of AD/S-76/41, which took effect on 2 July 2009, was made in accordance with Australia's obligations under the Convention on International Civil Aviation, and thus, no public consultation was required. Furthermore, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. The Manager, Airframe and Structures, in the Airworthiness Engineering Group, issued this AD on behalf of CASA, as mandated by subsection 84A(2) of the Act. In terms of obligations and requirements, CASA must diligently assess the ADs issued by the State of Design and determine whether they need to be implemented in Australia. If deemed necessary, CASA must issue an Australian AD to ensure compliance with safety standards. The State of Registry is also obligated to ensure the continuing airworthiness of the aircraft on its registry by developing or adopting necessary requirements. Regarding offences, penalties, or consequences for breaches, while the specific civil or criminal consequences are not outlined in this text, it is understood that non-compliance with ADs could potentially lead to severe penalties, including fines and sanctions, as these directives are crucial for maintaining aviation safety standards.
