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.
The Civil Aviation Safety Authority or its predecessors issued AD/BEECH 18/8 affecting Beech C-18S and AT-11 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 18/8. The cancellation will become effective on 20 December 2007. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, addresses the regulation of civil aviation to ensure safety and efficiency in the industry. This legislation provides the legal framework for the Australian Civil Aviation Safety Authority (CASA) to enforce safety standards and manage the risks associated with civil aviation activities. One significant aspect of the Act is its delegation of authority to CASA to issue airworthiness directives (ADs) through regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are crucial in maintaining the continuing airworthiness of aircraft types and aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Act and its regulations aim to uphold the highest safety standards in Australia's civil aviation sector, ensuring that the airworthiness of aircraft is maintained in accordance with both national and international obligations.
Scope and Application
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, establishes the framework for ensuring the safety of air navigation in Australia, with a specific focus on the issuance of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to make regulations that are critical for air navigation safety, and regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs are legislative instruments as defined under the Legislative Instruments Act 2003. In line with international obligations under Annex 8 to the Convention on International Civil Aviation, the State of Design retains responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, must ensure that Australian-registered aircraft meet necessary safety standards. Consequently, when an AD is issued by the State of Design, CASA evaluates the information and may issue a corresponding Australian AD to enforce the required safety measures. The cancellation of AD/BEECH 18/8 for Beech C-18S and AT-11 aircraft, effective from 20 December 2007, reflects CASA’s role in maintaining the safety standards as per international obligations, and no public consultation or Regulatory Impact Statement was required for this cancellation.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to enact regulations that serve the safety of air navigation. Within this framework, the Civil Aviation Safety Regulations 1998, regulation 39.001, grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. It is crucial to note that an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and, therefore, a legislative instrument as per section 6 of the Legislative Instruments Act 2003. These directives are instrumental in maintaining the continuing airworthiness of aircraft as stipulated by Annex 8 to the Convention on International Civil Aviation.
The obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are multifaceted. The State of Design, which is the country where an aircraft is designed, holds the primary responsibility for ensuring the continuing airworthiness of the aircraft type. This obligation includes providing any necessary information to States of Registry, which are responsible for the individual aircraft's airworthiness. CASA, as Australia's national airworthiness authority, must assess information from the State of Design and issue an Australian AD if necessary. This ensures that Australian-registered aircraft meet the safety standards set by international conventions and regulations.
The Act and the Regulations impose stringent requirements on all parties involved. For instance, CASA must rigorously evaluate airworthiness directives issued by the State of Design and determine whether an Australian AD is needed. If a condition is identified as unsafe, CASA has the authority to issue a directive mandating corrective actions. In cases where a directive is no longer necessary, such as when the unsafe condition has been resolved, CASA must cancel the AD, as was the case with AD/BEECH 18/8 concerning Beech C-18S and AT-11 aircraft, which was cancelled effective 20 December 2007.
In terms of offences, penalties, and consequences, the Civil Aviation Act 1988 does not explicitly outline specific penalties for breaches of ADs. However, non-compliance with an AD can lead to significant civil and criminal consequences. Civil penalties may include fines and enforcement actions against aircraft operators and manufacturers who fail to comply with ADs. Criminal penalties could also apply, especially if the non-compliance results in accidents or incidents that endanger safety. The seriousness of these consequences underscores the importance of adhering to ADs to maintain aviation safety standards.
