Overview
The Civil Aviation Regulations 1998 (CAR 1998) were enacted to provide comprehensive regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air operations within the country. A specific legislative instrument within this framework is the Airworthiness Directive AD/Y12/7, issued by the Civil Aviation Safety Authority (CASA) on 3 February 2003 and published in the Commonwealth of Australia Gazette on 26 February 2003. This directive addresses an identified unsafe condition in the reverse control system of certain Harbin Y12 Series Aeroplanes, specifically those with serial numbers 21, 22, 27, 33, 34, 36, 37, 42, 43, 46, and 47. The policy objective of this directive is to mandate the rework of the reverse control system to prevent inadvertent operation, ensuring the continued airworthiness and safety of these aircraft. The directive requires compliance prior to further flight and became effective on 20 March 2003.
Scope and Application
The Airworthiness Directive (AD) issued under the Civil Aviation Regulations 1998 applies specifically to Harbin Y12 Series aeroplanes with certain serial numbers, namely 21, 22, 27, 33, 34, 36, 37, 42, 43, 46, and 47. The directive mandates the rework of the reverse control system in accordance with the instructions provided in HAMC Service Bulletin Y12-76-0030 to prevent the inadvertent operation of the control system, thereby ensuring airworthiness. This AD applies nationally within the Commonwealth of Australia and is issued by a delegate of the Civil Aviation Safety Authority (CASA). The directive becomes effective on 20 March 2003, and any rework must be completed prior to further flight if not already done. The AD references a corresponding China CAAC AD CAD 92-Y12-002 Amdt 39-0736 for additional context. The AD was officially notified in the Commonwealth of Australia Gazette on 26 February 2003, providing public notice of the safety requirements.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105, issued under subregulation 39.1 (1), mandates the creation of Airworthiness Directives (AD) by the Civil Aviation Safety Authority (CASA) delegate to address identified safety issues in aircraft or aeronautical products. Section AD/Y12/7, specifically concerning the Harbin Y12 Series Aeroplanes, pertains to aircraft with specific serial numbers, namely 21, 22, 27, 33, 34, 36, 37, 42, 43, 46, and 47. The requirement of this AD is to perform rework on the reverse control system, following the detailed instructions in HAMC Service Bulletin Y12-76-0030. This rework is crucial to prevent any inadvertent operation of the control system, a concern corroborated by the China CAAC AD CAD 92-Y12-002 Amdt 39-0736. The compliance timeline demands that this rework must be completed before any further flights, unless it has already been carried out.
The obligations under this AD are clear and specific. Operators and owners of the affected Y12II aircraft must ensure that the rework on the reverse control system is completed in accordance with the HAMC Service Bulletin Y12-76-0030. This involves not only the physical rework but also adherence to the detailed instructions provided in the bulletin, ensuring that the safety issue is effectively addressed. The directive is effective immediately and requires compliance before any subsequent flight, underscoring the urgency and importance of the required actions.
Failure to comply with the AD can lead to significant consequences. While the specific civil or criminal penalties are not detailed in the AD itself, non-compliance with ADs generally can result in severe penalties under the Civil Aviation Act 1988 and Civil Aviation Regulations 1998. These can include fines, imprisonment, or both, depending on the severity of the breach and the impact on aviation safety. The AD's emphasis on the urgency of the rework indicates the potential seriousness of any non-compliance, suggesting that CASA takes such issues very seriously. Operators and owners must therefore ensure strict adherence to the directive to avoid these severe repercussions.
