CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most ICAO Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
CASA issued AD/BN-2/35 Amdt 2 in respect of Pilatus Britten-Norman BN-2 Series Aeroplanes. As a result of a request from industry CASA has reviewed this AD and has amended it to increase the retirement life from 28,000 hours to 30,000 hours based on advice from the manufacturer for the BN-2A model only. The amended AD, AD/BN-2/35 Amdt 3 will become effective on 9 August 2010. This AD cancels and replaces the previous issue.
This amendment represents a reduced maintenance burden for operators. CASA has not consulted with the Australian industry and public as there are no safety issues raised by this amendment.
The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Continuing Airworthiness, Airworthiness and Engineering Branch, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with Section 94(1) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, establishes a regulatory framework for civil aviation safety, including the issuance of airworthiness directives to ensure the safety of air navigation. The Act allows the Governor-General to make regulations for the purposes of the Act, with the Civil Aviation Safety Regulations 1998 providing specific mechanisms for the issuance of airworthiness directives. These directives, which are considered legislative instruments, are essential for maintaining the continuing airworthiness of aircraft and are issued by civil aviation authorities in accordance with international standards set by ICAO. The Civil Aviation Safety Authority (CASA) acts as Australia’s national airworthiness authority, responsible for assessing and issuing such directives when necessary, thereby ensuring compliance with international and domestic safety standards. The authority to issue these directives is crucial in addressing the need for consistent and rigorous safety measures across the aviation industry, thereby protecting public safety and maintaining the integrity of the national airspace.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998 under the Civil Aviation Act 1988 provide authority for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft registered in Australia. These regulations empower CASA to mandate safety requirements on specific types of aircraft or aeronautical products, thus applying to all aircraft and products within the Australian register. This includes both domestic and international aircraft operating within Australia, thereby extending its jurisdictional reach to all aviation activities within the nation's airspace. ADs, being legislative instruments, are subject to disallowance and must adhere to the legislative requirements set out in the Legislative Instruments Act 2003. These directives serve to implement the continuing airworthiness obligations of both the State of Design and the State of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation. The regulations do not include specific exclusions or exemptions, except for those outlined in the ADs themselves, which detail the aircraft types and specific safety measures applicable. Additionally, the issuance and amendment of ADs are often influenced by international standards and practices, ensuring that Australia's aviation safety measures are aligned with global benchmarks.
Key Provisions
Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations aimed at ensuring the safety of air navigation, and under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 46A of the Acts Interpretation Act 1901, along with subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, confirms that these ADs are disallowable instruments and, thus, legislative instruments under section 6 of the Legislative Instruments Act 2003. This means that ADs have legal standing and are binding upon the entities they govern.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure this to States of Registry. The State of Registry, in turn, is responsible for the continuing airworthiness of individual aircraft, developing or adopting requirements to maintain it. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA must assess this information and, if necessary, issue an Australian AD to enforce the requirements from the State of Design. For example, CASA issued AD/BN-2/35 Amdt 2 concerning Pilatus Britten-Norman BN-2 Series Aeroplanes. Following industry requests, CASA reviewed and amended this AD to extend the retirement life from 28,000 hours to 30,000 hours for the BN-2A model, with the amended AD, AD/BN-2/35 Amdt 3, set to take effect on 9 August 2010.
The ADs issued under these regulations impose specific obligations on the parties they govern, primarily focusing on compliance with airworthiness requirements to ensure the safety and continued airworthiness of aircraft. Operators of the affected aircraft must adhere to the directives issued, which may include mandatory inspections, maintenance procedures, and modifications. These obligations are critical to maintaining the safety standards set by international and domestic aviation authorities. CASA, as the national airworthiness authority, plays a pivotal role in monitoring compliance and enforcing these directives.
Non-compliance with airworthiness directives can lead to significant consequences. Civil Aviation Safety Regulations may outline specific offences and penalties for breaching ADs, which could include fines and other financial penalties. Additionally, operators failing to adhere to ADs may face operational restrictions or even the grounding of affected aircraft, potentially leading to severe operational disruptions and safety risks. The exact penalties and consequences depend on the specific regulations and the severity of the breach, but they are designed to ensure strict adherence to safety standards.
