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 raised AD/CESSNA 400/40 Amendment 13 in 1995 to correct an unsafe situation on Cessna 400 model aircraft. AD/CESSNA 400/40 imposes a retirement life on these aircraft to manage structural fatigue. Structural fatigue can also be managed by an inspection program, such as the Cessna Structural Inspection Document (SID) program. CASA has now amended AD/CESSNA 400/40 to Amendment 14 to encourage use of the Cessna SID program and to remove the life limit for those aircraft maintained to the SID. The State of Design for these types, the USA, has not yet taken action to address structural fatigue. AD/CESSNA 400/40 Amendment 14 will become effective on 21 December 2006. This AD cancels and replaces the previous issue.
CASA has not consulted with the Australian industry and public in amending this AD, because the amendment reduces the regulatory burden on industry and allows aircraft to remain in service well past the previous retirement life as long as it is maintained to the SID program.
The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted by the Australian Parliament to provide a comprehensive framework for the regulation of civil aviation in Australia. One of its key functions is to ensure the safety of air navigation, which is reinforced by the Civil Aviation Safety Regulations 1998. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to address specific safety issues for particular aircraft or aeronautical products. The ADs are considered legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and regulated by the Legislative Instruments Act 2003. This legislative framework ensures that Australia's airworthiness standards are in line with the requirements of the Convention on International Civil Aviation and other international agreements, thereby enhancing the safety and reliability of civil aviation in the country.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, encompasses the issuance of airworthiness directives (ADs) under the authority of the Civil Aviation Safety Authority (CASA). This legislation applies to the continuing airworthiness of aircraft and aeronautical products registered in Australia, ensuring compliance with safety regulations. CASA, as Australia's national airworthiness authority, is tasked with assessing information from the State of Design and issuing ADs when necessary to mandate specific safety requirements. The geographic reach of these regulations is national, with the aim of harmonising Australian standards with those of other ICAO Contracting States. The ADs are legislative instruments that are disallowable, meaning they can be reviewed and potentially disallowed by Parliament. Notably, the issuance of ADs does not require a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The scope of the legislation extends to mandating specific maintenance actions, such as those outlined in AD/CESSNA 400/40 Amendment 14, which deals with structural fatigue management for certain aircraft types. This particular AD has been amended to encourage the use of specific inspection programs, thereby extending the operational life of compliant aircraft.
Key Provisions
The Civil Aviation (Safety) Regulations 1998, specifically under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD, as defined in subregulation 39.001(5), is considered a disallowable instrument under the Acts Interpretation Act 1901, and therefore, a legislative instrument as per the Legislative Instruments Act 2003. These directives are critical for maintaining the continuing airworthiness of aircraft and ensuring compliance with safety standards set forth by the Convention on International Civil Aviation.
The obligations placed on the parties governed by this legislation are multifaceted. The State of Design is primarily responsible for the continuing airworthiness of an aircraft type, providing necessary information to the States of Registry. The State of Registry, in turn, is tasked with developing or adopting requirements to ensure the airworthiness of aircraft on its register. In the case of Australia, CASA is responsible for assessing ADs issued by the State of Design and, if deemed necessary, issuing corresponding Australian ADs. This includes the recent amendment to AD/CESSNA 400/40, which addresses structural fatigue in Cessna 400 model aircraft. CASA's decision to amend this directive to encourage the use of the Cessna Structural Inspection Document (SID) program and to remove the life limit for compliant aircraft, demonstrates a proactive approach to balancing safety with operational efficiency.
Failure to comply with an AD can have significant legal and financial repercussions. Under section 98 of the Civil Aviation Act 1988, non-compliance with an AD can result in enforcement actions by CASA. While specific penalties are not detailed in the provided text, general civil and criminal penalties for non-compliance with aviation regulations can include fines, imprisonment, or both, depending on the severity of the breach. The amendment to AD/CESSNA 400/40, which removes the life limit for aircraft maintained according to the SID program, aims to reduce regulatory burden without compromising safety, thus minimising potential legal ramifications for compliant operators.
