AD/PROP/5 - Incomplete Maintenance

Overview

The Civil Aviation Act 1988 was enacted to provide a legislative framework for the safety and efficiency of civil aviation in Australia. It empowers the Governor-General to create regulations that ensure the safety of air navigation, as exemplified by the Civil Aviation Safety Regulations 1998. Specifically, the Act enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain aircraft and aeronautical products, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. This regulatory power is crucial for maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation, which places the responsibility on the State of Design and the State of Registry. The policy objective behind these regulations is to harmonise Australia’s approach to aircraft safety with international standards, ensuring that Australian aircraft meet global safety benchmarks.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for issuing airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) having the authority to issue such directives under regulation 39.001. These directives apply to specific types of aircraft or aeronautical products and are essential for ensuring the continuing airworthiness of aircraft. The scope of these regulations extends to mandating requirements that have been assessed and approved by CASA, particularly when responding to directives issued by the State of Design, such as the United States in the case of propellers by Hartzell, McCauley, and Sensenich. The ADs are issued under Australia’s obligations under the Convention on International Civil Aviation and are considered legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901. The issuance of these directives does not require public consultation, as determined by the Office of Regulatory Review, and no Regulatory Impact Statement is necessary. These regulations apply to all aircraft registered in Australia and ensure compliance with international standards for airworthiness.

Key Provisions

The Civil Aviation Act 1988, under section 98, empowers the Governor-General to make regulations that contribute to 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) concerning specific types of aircraft or aeronautical products. According to subregulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, they are legislative instruments under section 6 of the Legislative Instruments Act 2003. Under Annex 8 to the Convention on International Civil Aviation, the State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type, requiring them to provide necessary information to ensure this airworthiness to relevant States of Registry. ADs are a prevalent form of continuing airworthiness information and are issued by most ICAO Contracting States. Conversely, the State of Registry of an individual aircraft bears the responsibility for ensuring the continuing airworthiness of that aircraft. This entails developing or adopting requirements to maintain airworthiness. When a State of Design issues an AD against an aircraft type registered in Australia, CASA, as Australia's national airworthiness authority, must evaluate the information and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design. In the case of the United States Federal Aviation Administration (FAA) issuing AD 2005-14-11 concerning Hartzell, McCauley, and Sensenich propellers, the United States is the State of Design for these propeller types. CASA has evaluated this AD and subsequently issued Australian AD/PROP/5, which will take effect on 29 September 2005. Given that this AD is issued due to Australia's obligations under the Convention on International Civil Aviation and in response to an AD raised by the relevant State of Design, no consultation of the Australian public has occurred regarding this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement. The AD has been made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A(2) of the Act. Under the Civil Aviation Act 1988, any breach of the provisions, including failure to comply with an airworthiness directive, can result in various civil and criminal penalties. For instance, section 25 of the Act outlines that a person who contravenes a civil aviation regulation commits an offence, which can lead to fines and imprisonment. The specific maximum penalties for such breaches depend on the nature and severity of the violation, and they are stipulated in the relevant sections of the Act and associated regulations. It is critical for parties and entities governed by the Act to adhere strictly to the requirements and obligations set forth to avoid these potential consequences.
