AD/RB211/45 - Air - IP Cabin Air Offtake Ducting

Overview

The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations for this purpose, with the overarching goal of enhancing the safety of air navigation. One such regulation, 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 authority was established to address the need for continuing airworthiness of aircraft, in line with international standards and obligations under the Convention on International Civil Aviation. The ADs are intended to ensure that aircraft meet the necessary safety standards by mandating compliance with specific safety requirements. In this context, CASA, as Australia’s national airworthiness authority, assesses information from the State of Design and, when necessary, issues corresponding ADs to enforce compliance with international safety standards.

Scope and Application

The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the regulation of civil aviation safety in Australia. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These directives are legislative instruments and are issued to ensure compliance with international standards for the continuing airworthiness of aircraft. For instance, if a State of Design issues an AD for an aircraft type registered in Australia, CASA must review and, if necessary, issue a corresponding Australian AD. This ensures that Australian aircraft meet the safety standards set forth by the international Convention on International Civil Aviation. The ADs are not subject to public consultation as they respond to international directives and are deemed to have no impact on human rights or freedoms. The Manager, Continuing Airworthiness in the Airworthiness and Engineering Branch at CASA issues these directives on behalf of CASA, in line with the provisions of the Civil Aviation Act 1988.

Key Provisions

The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance of airworthiness directives (ADs) (sections 98 and 39.001). According to regulation 39.001(5), ADs are considered disallowable instruments, thus falling under the legislative instruments category as per section 6 of the Legislative Instruments Act 2003. The State of Design, as per Annex 8 to the Convention on International Civil Aviation, holds primary responsibility for the continuing airworthiness of an aircraft type, and is mandated to provide necessary information to ensure the continuing airworthiness of a type to appropriate States of Registry. The State of Registry, on the other hand, is tasked with ensuring the continuing airworthiness of individual aircraft by developing or adopting requisite requirements. When a State of Design issues an AD for an aircraft type registered in Australia, the Civil Aviation Safety Authority (CASA) must assess this information and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design. Under these regulations, CASA, Australia's national airworthiness authority, has issued an AD concerning the periodic inspection of bleed-air ducting on Rolls-Royce RB211-524 engines in Boeing 747 and Boeing 767 aircraft. This AD, AD/RB211/45, mandates compliance with AD G-029-04-90 issued by the Civil Aviation Authority of the United Kingdom, the State of Design for the Rolls-Royce RB211 engine. The AD will become effective on 30 April 2012. This directive is issued in compliance with Australia's obligations under the Convention on International Civil Aviation. It is important to note that no consultation with the Australian public was conducted because this AD is a direct response to an AD issued by the relevant State of Design. Furthermore, the Office of Regulatory Review has concluded that ADs do not require a Regulatory Impact Statement. The AD is compatible with the human rights and freedoms recognised or declared in the international instruments listed in section 3 of the Human Rights (Parliamentary Scrutiny) Act 2011. The instrument sets out technical requirements and does not engage any of the applicable rights or freedoms. The AD was made by the Manager, Continuing Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94(1) of the Civil Aviation Act 1988. Non-compliance with an AD can result in serious consequences. Under the Civil Aviation Act 1988, failure to comply with an AD can lead to offences, with potential penalties including fines and imprisonment. Specifically, section 348 of the Act provides for fines of up to $21,000 for individuals and $105,000 for corporations, along with potential imprisonment for up to two years. Additionally, CASA can take enforcement actions such as grounding aircraft, denying or suspending airworthiness certificates, and prosecuting operators who fail to comply with ADs. These actions can significantly impact the operations and reputation of aviation companies, making compliance with ADs a critical aspect of aviation safety and regulatory adherence.
