AD/BEECH 90/103 - Flight Control System

Overview

The Civil Aviation Act 1988 was enacted to provide a comprehensive legal framework for the regulation of civil aviation in Australia, aiming to ensure safety, efficiency, and the orderly development of air transport. One of the key mechanisms introduced by this Act is the issuance of airworthiness directives (ADs) to maintain and ensure the continuing airworthiness of aircraft. Section 98 of the Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, including the establishment of ADs through regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and oversight by the Legislative Instruments Act 2003. The Civil Aviation (Administrative) Regulations 1990 further detail the processes for AD issuance and compliance. The objective is to align Australia's aviation safety standards with international obligations under the Convention on International Civil Aviation, ensuring that the continuing airworthiness of aircraft is maintained in accordance with globally accepted practices.

Scope and Application

The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments that fall under the purview of the Civil Aviation Act 1988. They are designed to ensure the safety of air navigation and are issued in compliance with Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design maintains responsibility for the continuing airworthiness of aircraft types. In Australia, CASA, as the national airworthiness authority, is obligated to assess and, if necessary, issue ADs to enforce the requirements of the State of Design. For instance, in response to the US Federal Aviation Administration’s AD 2007-12-06 concerning Hawker Beechcraft C90 model aircraft, CASA issued AD/BEECH 90/103, effective from 30 August 2007. Given that these directives are issued in response to international obligations and specific design state requirements, they do not necessitate public consultation or a Regulatory Impact Statement. The ADs are developed under the authority vested in CASA by the Civil Aviation Act 1988 and are managed by the Manager, Airframes within CASA’s Manufacturing, Certification and New Technologies Office.

Key Provisions

The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, establishes the framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. Section 98 of the Act empowers the Governor-General to make regulations that serve the safety interests of air navigation, and regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. This regulatory mechanism is further reinforced by subregulation 39.001(5), which clarifies that ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901, thus classifying them as legislative instruments. Under the obligations set forth by the Act and the Regulations, CASA, as Australia’s national airworthiness authority, is required to assess any ADs issued by the State of Design of an aircraft type. This responsibility is underscored by Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design has the overarching responsibility for ensuring the continuing airworthiness of aircraft types. The State of Registry, which in this context refers to Australia, must then develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its territory. Consequently, when the United States, as the State of Design for the Hawker Beechcraft C90 model aircraft, issued AD 2007-12-06, CASA assessed this directive and issued its own corresponding AD, AD/BEECH 90/103, which was scheduled to become effective on 30 August 2007. The issuance of ADs under these provisions does not require consultation with the Australian public nor does it necessitate a Regulatory Impact Statement, as determined by the Office of Regulatory Review. This reflects the critical and urgent nature of airworthiness directives, which are issued to promptly address safety concerns without the need for public consultation. The Manager, Airframes in the Manufacturing, Certification and New Technologies Office, acting on behalf of CASA, issued AD/BEECH 90/103 in accordance with subsection 84A(2) of the Act, ensuring compliance with Australia’s international obligations under the Convention on International Civil Aviation. In the event of non-compliance with an AD, the Civil Aviation Act 1988 imposes significant consequences. Offences under the Act can lead to both civil and criminal penalties. For example, failure to comply with an AD can result in a fine of up to $275,000 for an individual and up to $1.375 million for a body corporate, as stipulated by the applicable legislative provisions. Additionally, non-compliance can lead to criminal charges, with potential imprisonment terms for responsible individuals, further emphasising the seriousness with which the Act treats airworthiness compliance.
