AD/AC-100/14 - Aileron and Flap Hinge Pins - Inspection - CANCELLED

Overview

The Civil Aviation Act 1988, enacted by the Australian Parliament, was introduced to regulate civil aviation safety in Australia, ensuring the safety of air navigation as outlined in section 98 of the Act. The Civil Aviation Safety Regulations 1998, made under the Act, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products, as stated in regulation 39.001. These ADs serve as legislative instruments under the Legislative Instruments Act 2003, as noted in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998. The ADs are a response to the international obligation under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has the responsibility for the continuing airworthiness of an aircraft type. CASA, as Australia’s national airworthiness authority, must assess and, if necessary, issue Australian ADs to ensure compliance with international safety standards. The ADs do not require consultation with the public, as determined by the Office of Best Practice Regulation, and are issued by CASA in accordance with the Civil Aviation Act 1988.

Scope and Application

The Civil Aviation Act 1988 and its associated regulations, such as the Civil Aviation Safety Regulations 1998, govern the issuance of airworthiness directives (ADs) within Australia. These regulations apply to all entities involved in civil aviation, including aircraft manufacturers, operators, and maintenance providers, and pertain to the maintenance and airworthiness of aircraft registered in Australia. The Act and its regulations ensure that aircraft remain airworthy and safe to operate, with the Civil Aviation Safety Authority (CASA) acting as the national airworthiness authority responsible for assessing and issuing ADs in accordance with international standards set by the International Civil Aviation Organization (ICAO). ADs are legislative instruments and are subject to disallowance as per the Acts Interpretation Act 1901. The application of these regulations is not limited by geographic jurisdiction within Australia, encompassing both Commonwealth and state or territory levels. Any exclusions or exemptions from the application of these regulations are not explicitly mentioned in the text, suggesting that the regulations apply broadly across the aviation sector. The scope of the ADs is further extended through subordinate instruments that may be issued under the authority of the Civil Aviation Act 1988.

Key Provisions

The key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, particularly in relation to airworthiness directives (ADs), are outlined in section 98 of the Act and regulation 39.001 of the Regulations. The Act empowers the Governor-General to make regulations that promote air navigation safety, while regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain aircraft or aeronautical products. According to subregulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments under section 6 of the Legislative Instruments Act 2003. The obligations and requirements imposed by the Act and Regulations centre around the continuing airworthiness of aircraft. The State of Design has the primary responsibility for ensuring the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry, which includes Australia. CASA, as Australia's national airworthiness authority, must assess the information provided by the State of Design and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design. This ensures that aircraft registered in Australia meet international safety standards. There are no specific offences, penalties, or consequences outlined in the provided text for breaches of ADs or non-compliance with the Act and Regulations. However, it is important to note that ADs are critical to maintaining the safety of air navigation, and failure to comply with these directives could result in severe consequences, including potential legal action by CASA. The precise penalties for non-compliance would depend on the specific circumstances and the severity of the breach, and are likely to be determined under the broader framework of aviation safety laws. The process for issuing and cancelling ADs, as demonstrated in the example of AD/AC-100/14 for S.L. Industries Commander 100 and Volair 10 series aircraft, involves careful assessment by CASA. When an unsafe condition is identified, an AD is issued to address it. In this instance, CASA assessed the AD and determined that the unsafe condition no longer existed, leading to the cancellation of the AD. This cancellation was made in accordance with Australia's obligations under the Convention on International Civil Aviation and did not require consultation with the public or a Regulatory Impact Statement. Finally, the AD in question was made by the Manager, Airframe and Structures, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act. This highlights the structured and regulated process involved in managing airworthiness directives within Australia's aviation regulatory framework.
