AD/EMB-145/13 - Rudder II Skin, Hinge Fittings, Attachment Fasteners, and Control Rods

Overview

The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia, ensuring the safety of air navigation and the continuing airworthiness of aircraft. This Act empowers the Governor-General to create regulations in the interests of air navigation safety. One such regulation, established under 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. These directives are essential for maintaining the safety standards required by international agreements, such as Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has the primary responsibility for the continuing airworthiness of aircraft types. CASA, as Australia's national airworthiness authority, is obligated to assess and, where necessary, issue Australian ADs in response to those issued by the relevant State of Design, thereby ensuring compliance with international safety standards and obligations.

Scope and Application

The Civil Aviation Safety Regulations 1998, as amended, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. These directives apply to specific types of aircraft or aeronautical products and are mandated under regulation 39.001. An AD is considered a legislative instrument under the Legislative Instruments Act 2003, and its disallowance is governed by section 46A of the Acts Interpretation Act 1901. The ADs are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as having overall responsibility for the continuing airworthiness of an aircraft type. In Australia, CASA, as the national airworthiness authority, assesses the information from the State of Design and issues corresponding Australian ADs when necessary. This ensures that Australian-registered aircraft meet the continuing airworthiness requirements set by the State of Design. The issuance of ADs is governed by Australia's obligations under international aviation conventions and does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.

Key Provisions

The Civil Aviation Act 1988, through section 98, empowers the Governor-General to establish regulations that support the Act and ensure the safety of air navigation. 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. These ADs, as noted in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and, therefore, are legislative instruments under section 6 of the Legislative Instruments Act 2003. In line with Annex 8 to the Convention on International Civil Aviation, the State of Design, which is the country responsible for designing the aircraft type, must ensure the continuing airworthiness of the aircraft type and provide necessary information to the State of Registry, which is the country where the aircraft is registered. Under the Civil Aviation Safety Regulations 1998, both the State of Design and the State of Registry have distinct responsibilities regarding the airworthiness of aircraft. The State of Design must issue ADs to ensure the continuing airworthiness of aircraft types, while the State of Registry must develop or adopt requirements to maintain this airworthiness. In the case of Australia, CASA, as the national airworthiness authority, must assess ADs issued by the State of Design and, if deemed appropriate, issue corresponding Australian ADs to enforce the necessary requirements. This process was followed when the Brazilian Authority issued AD 2005-09-02R2 concerning the Embraer 135 and 145 models, leading CASA to issue Australian AD/EMB-145/13, which became effective on 31 July 2008. Given the international nature of this AD and Australia's obligations under the Convention on International Civil Aviation, no consultation of the Australian public was required, as determined by the Office of Best Practice Regulation. Additionally, this AD does not necessitate a Regulatory Impact Statement. The Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, made this AD in accordance with subsection 84A(2) of the Civil Aviation Act 1988. The obligations imposed by the Civil Aviation Safety Regulations 1998 on the parties governed by this legislation are multifaceted. The State of Design must ensure the continuing airworthiness of aircraft types and provide relevant information to the State of Registry. The State of Registry, in turn, must develop or adopt requirements to maintain the airworthiness of aircraft registered within its jurisdiction. CASA, as the national airworthiness authority in Australia, has the responsibility to assess ADs issued by the State of Design and to issue corresponding Australian ADs when necessary. This ensures that all aircraft registered in Australia comply with the safety standards set forth by international agreements and national regulations. Failure to comply with the requirements set out in the airworthiness directives can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can result in various civil and criminal penalties. Civil penalties may include fines and other financial penalties, while criminal penalties can include imprisonment, depending on the severity of the breach and the discretion of the court. The maximum penalties for such breaches are specified in the relevant sections of the Act and may vary based on the nature of the offence and the circumstances surrounding it. Ensuring compliance with ADs is critical for maintaining the safety and airworthiness of aircraft operating within Australian jurisdiction.
