AD/B747/348 - Outboard Strut Spring Beam Midpivot Bolt and Midpivot Bolt Access Door

Overview

The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, was designed to provide a legislative framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in the industry. The Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, as evidenced by the subsequent creation of the Civil Aviation Safety Regulations 1998. These regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs), which are legislative instruments aimed at maintaining the airworthiness of aircraft and aeronautical products. These directives are critical for ensuring that aircraft continue to meet safety standards throughout their operational lives, aligning with international obligations under the Convention on International Civil Aviation. The issuance of an Australian airworthiness directive, such as AD/B747/348 for Boeing B747 model aircraft, exemplifies the practical application of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. In this instance, CASA has responded to an airworthiness directive issued by the United States Federal Aviation Administration (FAA), the State of Design for the Boeing B747. The process underscores CASA’s role in upholding Australia’s commitments to international aviation safety standards, without necessitating public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. This directive is issued under the authority vested in CASA by the Act, ensuring compliance with international standards and the ongoing safety of aircraft registered in Australia.

Scope and Application

The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This legislative framework ensures the continuing airworthiness of aircraft and aeronautical products, reflecting Australia’s obligations under the Convention on International Civil Aviation. The State of Design, responsible for the type design of an aircraft, must provide necessary information to ensure airworthiness, while the State of Registry, where the aircraft is registered, is tasked with implementing these requirements. In response to a United States Federal Aviation Administration (FAA) AD for Boeing B747 model aircraft, CASA has issued an Australian AD to mandate the requirements for aircraft registered in Australia. The AD is issued under the authority of the Civil Aviation Act and does not require public consultation or a Regulatory Impact Statement, as it pertains to international obligations and the assessment of an AD from the relevant State of Design.

Key Provisions

The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are mandated by section 98 of the Civil Aviation Act 1988 and are crafted to maintain the safety of air navigation. Regulation 39.001(5) further clarifies that these ADs are legislative instruments under the Acts Interpretation Act 1901 and Legislative Instruments Act 2003. Under Annex 8 to the Convention on International Civil Aviation, the State of Design holds the responsibility for ensuring the continuing airworthiness of an aircraft type, and must provide necessary information to relevant States of Registry. The State of Registry, in turn, is responsible for the continuing airworthiness of individual aircraft within its registry. In the context of the Boeing B747 model aircraft, the United States, as the State of Design, issued AD 2006-12-03. CASA, acting on behalf of Australia, assessed this directive and subsequently issued Australian AD/B747/348, which will take effect on 3 August 2006. This action aligns with Australia’s obligations under the Convention on International Civil Aviation. Since this AD responds to an international directive, it was not subject to consultation with the Australian public. Additionally, the Office of Regulatory Review has determined that such ADs do not require a Regulatory Impact Statement. The AD was formulated by the Manager, Airframes, within CASA’s Manufacturing, Certification and New Technologies Office, in accordance with subsection 84A(2) of the Act. The obligations imposed by the AD on parties and entities are primarily focused on compliance with the specified airworthiness requirements. Aircraft operators, maintenance organisations, and other relevant entities must adhere to the mandates set out in the AD to ensure the aircraft remain airworthy. Failure to comply with these directives could result in severe consequences, including grounding of the affected aircraft until the required actions are completed. The AD outlines specific maintenance actions, inspections, and repairs that must be carried out within specified timeframes. In terms of enforcement and consequences, any breaches of the ADs can lead to serious penalties. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can result in significant civil or criminal penalties. For instance, an individual found guilty of contravening an AD can face fines up to $165,294 and imprisonment for up to five years. Similarly, corporations may incur penalties up to $826,470. The severity of these penalties underscores the critical importance of adhering to the ADs to ensure the safety and airworthiness of aircraft.
