AD/DO 228/12 Amdt 1 - De-bonding of Surface Protection on Rudders and Elevators

Overview

The Civil Aviation Act 1988, enacted to regulate and ensure the safety of air navigation in Australia, provides the framework within which the Civil Aviation Safety Regulations 1998 operate. These regulations include provisions for the issuance of airworthiness directives (ADs) as a means to ensure the continuing airworthiness of aircraft. The Civil Aviation (Safety) Regulations 1998 specifically empower the Civil Aviation Safety Authority (CASA) to issue such directives, which are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The Civil Aviation Act 1988 was introduced to address the need for comprehensive regulation of civil aviation to enhance safety and compliance with international standards, particularly under the Convention on International Civil Aviation. The policy objective is to ensure that Australian aviation standards are consistent with international obligations and practices. The ADs are issued in accordance with Australia's responsibilities under the Convention and in response to directives from the relevant State of Design, such as the German LBA, without requiring public consultation due to the international nature of the obligations.

Scope and Application

The Civil Aviation Safety Regulations 1998, pursuant to the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives serve as legislative instruments under the Acts Interpretation Act 1901 and are integral to maintaining the continuing airworthiness of aircraft, aligning with international standards set by the Convention on International Civil Aviation. The State of Design, which in this case is Germany for the Dornier Do 228 model aircraft, is responsible for issuing ADs that address design-specific issues, while the State of Registry, here represented by CASA, must implement these directives to ensure compliance within its jurisdiction. The ADs are thus mandated by international obligations and do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. CASA issues these directives to enforce safety standards and ensure that aircraft registered in Australia meet the necessary requirements to maintain their airworthiness.

Key Provisions

The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This provision is grounded in section 98 of the Civil Aviation Act 1988, which allows the Governor-General to make regulations for the safety of air navigation. Subregulation 39.001(5) further clarifies that an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus a legislative instrument according to section 6 of the Legislative Instruments Act 2003. These ADs are integral to ensuring the continuing airworthiness of aircraft, a responsibility held by the State of Design under Annex 8 of the Convention on International Civil Aviation. For instance, when the German Federal Aviation Office (LBA) issued AD 2007-350R1 concerning Dornier Do 228 model aircraft in 2009, CASA, as Australia's national airworthiness authority, had to assess this information and subsequently issue a corresponding Australian AD to mandate the requirements set by the German LBA. The obligations placed on parties by this legislation are significant. The State of Design, in this case, Germany, is tasked with providing necessary information to ensure the continuing airworthiness of aircraft types, aligning with Annex 8 of the Convention on International Civil Aviation. The State of Registry, in this context, Australia, must then develop or adopt requirements to maintain the airworthiness of aircraft within its jurisdiction. CASA's role is to assess information from the State of Design and, if necessary, issue an Australian AD to enforce the required measures. This ensures that all aircraft operating within Australia meet the necessary safety standards. Moreover, the AD process ensures that the Australian public is protected by adhering to internationally recognised safety protocols. Failure to comply with an AD can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in both civil and criminal penalties. Civil penalties may include fines, while criminal penalties can include imprisonment. The exact penalties depend on the severity of the breach and the specific provisions of the AD. It is important for all parties, including aircraft operators, manufacturers, and maintenance providers, to be aware of their obligations under these directives to avoid potential legal repercussions. The stringent enforcement of these directives underscores the importance of maintaining high safety standards in the aviation industry. In summary, the AD process, governed by sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, mandates that CASA issue directives to ensure the airworthiness of aircraft within Australia. These directives are based on international standards and require cooperation between the State of Design and the State of Registry. Compliance is mandatory, with significant penalties for non-compliance, highlighting the critical nature of maintaining safety in civil aviation.
