AD/B747/379 - Airworthiness Limitations & Inspections - Fuel Tank Systems - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to ensure the safety of air navigation, providing a legislative framework that includes the issuance of airworthiness directives (ADs) for aircraft and aeronautical products. In the interests of continuing airworthiness, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue these directives, which are essential for maintaining the safety standards of aircraft as per Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Act 1988, as amended, facilitates the collaboration between the State of Design and the State of Registry in ensuring that aircraft meet international safety standards. The Manager, Continuing Airworthiness in the Airworthiness and Engineering Branch, acting on behalf of CASA, has the authority under the Act to issue such directives and has exercised this authority by cancelling AD/B747/379 for Boeing 747 series aeroplanes, effective from 16 November 2009, due to its supersession by the United States Federal Aviation Administration's AD 2008-10-07R1.

Scope and Application

The Civil Aviation Safety Regulations 1998, as amended, under section 98 of 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, ensuring compliance with safety standards. These regulations apply to all aircraft registered in Australia and any entities or individuals involved in the operation, maintenance, or manufacture of such aircraft. ADs serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft as per Annex 8 to the Convention on International Civil Aviation, with the State of Design having the primary responsibility for providing necessary information to the State of Registry. CASA, acting on behalf of Australia as the national airworthiness authority, is mandated to assess and, if necessary, issue Australian ADs to enforce the requirements stipulated by the State of Design. The scope of these regulations extends nationally within Australia, aligning with international standards set by the International Civil Aviation Organization (ICAO). Subordinate instruments, such as specific ADs, further refine and implement these regulations, ensuring the safety of air navigation and compliance with both domestic and international aviation safety standards.

Key Provisions

The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides a framework for the regulation of airworthiness directives (ADs). Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to create regulations to enhance the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument, meaning it can be annulled by a resolution of either House of the Parliament, and is considered a legislative instrument under the Legislative Instruments Act 2003. The obligations imposed by the Act and its Regulations are primarily on CASA, as the national airworthiness authority, and on the State of Registry for individual aircraft. CASA must assess any ADs issued by the State of Design and, if deemed necessary, issue an Australian AD to enforce the requirements. The State of Design, typically the country where the aircraft is manufactured, has the responsibility to provide necessary information to ensure the continuing airworthiness of aircraft types. The State of Registry, in this case, Australia, must develop or adopt requirements to maintain the airworthiness of aircraft registered within its jurisdiction. This collaborative effort ensures that all parties involved adhere to safety standards mandated by international agreements, such as Annex 8 to the Convention on International Civil Aviation. Failure to comply with the requirements set out in an AD can result in serious consequences. The Civil Aviation Act 1988 and associated regulations impose strict penalties for non-compliance. For instance, individuals or entities that fail to adhere to an AD can face civil penalties, including fines, and in severe cases, criminal charges. The exact penalties can vary depending on the specific breach and the severity of the safety risk posed. It is important for all stakeholders, including aircraft operators, maintenance providers, and regulatory authorities, to strictly follow the mandated ADs to avoid these repercussions. In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for the issuance and enforcement of airworthiness directives. CASA, as the regulatory body, plays a pivotal role in ensuring that these directives are appropriately assessed and implemented. Both the State of Design and the State of Registry have distinct responsibilities that are critical for maintaining the safety and airworthiness of aircraft. Non-compliance with these directives can lead to significant civil and criminal penalties, underscoring the importance of adhering to the regulatory requirements.
