AD/RAD/47 Amdt 3 - Periodic Testing of ATC Transponders

Overview

The Civil Aviation Safety Regulations 1998 (CASR 1998) were enacted to ensure the safety of civil aviation in Australia, providing a regulatory framework that the Civil Aviation Safety Authority (CASA) utilises to issue airworthiness directives (AD). The AD/RAD/47 Amdt 3, made under section 98 of the Civil Aviation Act 1988, aims to address a previously identified unsafe situation with air traffic control transponders by specifying the periodic testing requirements. The amendment narrows the scope of the AD to aircraft governed by Part 42 of CASR 1998, thereby eliminating the duplication of requirements in Civil Aviation Order (CAO) 100.5 for other aircraft. This targeted approach ensures that safety directives are applied efficiently and effectively, without unnecessary overlap. CASA, exercising its powers under the Acts Interpretation Act 1901 and in accordance with international standards set by the Convention on International Civil Aviation, has made this amendment to improve the regulation of airworthiness in alignment with best practices.

Scope and Application

The AD/RAD/47 Amdt 3, issued by the Civil Aviation Safety Authority (CASA) under the authority conferred by the Civil Aviation Act 1988, pertains to the periodic testing of air traffic control (ATC) transponders, specifically focusing on aircraft to which Part 42 of the Civil Aviation Safety Regulations 1998 applies. This legislative instrument applies to aircraft operators and maintenance entities ensuring compliance with safety regulations for ATC transponders, aligning with international standards as outlined in Annex 8 of the Convention on International Civil Aviation. The amendment aims to streamline and refine existing requirements by limiting the scope of AD/RAD/47 Amdt 2, ensuring that only relevant aircraft are subject to the specific periodic testing directives. This amendment does not impose new requirements on entities that fall outside the scope of Part 42, which instead follow the requirements in Civil Aviation Order 100.5. The instrument operates nationally, encompassing all aircraft registered within Australia, and is designed to enhance safety and efficiency in air navigation.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CASR 1998) have been amended by AD/RAD/47 Amdt 3 to address the periodic testing of air traffic control (ATC) transponders. This amendment is specifically targeted at aircraft to which Part 42 of CASR 1998 applies (section 1). For aircraft not covered by Part 42, the requirements have been transitioned to Civil Aviation Order (CAO) 100.5. This amendment replaces the previous AD on this subject and includes minor changes to clarify the use of Mode A code 2100 and electron tube technology capable transponders during testing. Under this amendment, the obligations imposed on parties or entities governed by this Act primarily involve ensuring compliance with the periodic testing requirements for ATC transponders (section 2). This includes adhering to the specified intervals and procedures for testing, as outlined in the AD, to maintain the airworthiness of the aircraft. Compliance with these requirements is crucial to ensure the safety of air navigation and to meet international standards as set out in Annex 8 to the Convention on International Civil Aviation. Breaching the requirements set forth in AD/RAD/47 Amdt 3 can lead to various consequences, including the potential for the aircraft to be deemed unairworthy if the transponders are not tested and maintained according to the stipulated guidelines (section 3). This could result in the aircraft being grounded, leading to significant operational disruptions and financial penalties for the operators. While the AD itself does not explicitly state maximum penalties, non-compliance with airworthiness directives can result in civil penalties under CASR 1998, including fines and potential criminal charges if the breach results in a serious safety incident. The Civil Aviation Safety Authority (CASA) has determined that further consultation was not necessary for this amendment, as it is considered minor and does not substantially alter existing arrangements (section 4). This decision aligns with the provisions of the Legislative Instruments Act 2003. Additionally, a Regulation Impact Statement was not required for this AD, as it falls under a standing agreement between CASA and the Office of Best Practice Regulation. The compatibility of this legislative instrument with human rights has also been affirmed in a Statement of Compatibility with Human Rights, indicating that it does not engage any applicable rights or freedoms.
