COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Harbin Y12 Series Aeroplanes
AD/Y12/9 Central Control Pedestal 3/2003
Applicability: Y12 aeroplanes listed in Harbin Aircraft Manufacturing Corporation Service Bulletin (SB) Y12-76-0036 dated 3 August 1992.
Requirement: If not previously accomplished, modify the central control pedestal in accordance with SB Y12-76-0036.
This modification should be incorporated in conjunction with the modification to the flap motoreducer, SB Y12-27-0035 and AD/Y12/10 refers.
Note: China CAAC AD CAD92-Y012-04 Amdt 39-0811 refers.
Compliance: Before 30 June 2003.
This Airworthiness Directive becomes effective on 20 March 2003.
Background: This Directive requires the modification of the central control pedestal power lever reverse locking unit, the control switch panel and indicator light. These modifications are designed to prevent inadvertent operation of the reverse locking device at idle, which may cause the power lever to enter reverse.

The above AD is notified in the Commonwealth of Australia Gazette on 26 February 2003.
Overview
The Civil Aviation Regulations 1998 (CAR 1998) were enacted to provide a comprehensive regulatory framework governing the safety and operational standards of civil aviation in Australia. The legislation was introduced to address the need for a robust and consistent set of regulations to ensure the safety of the aviation industry. The Civil Aviation Safety Authority (CASA), as the delegate of the Australian Government, is responsible for administering and enforcing these regulations. One specific enactment within this framework is the Airworthiness Directive (AD) issued under subregulation 39.1(1) of CAR 1998, aimed at addressing identified safety issues in aircraft and aeronautical products. The policy objective of these directives is to ensure that any potential safety hazards are promptly identified and rectified to maintain the highest safety standards in the aviation sector.
Scope and Application
The Airworthiness Directive (AD) AD/Y12/9 applies specifically to Y12 aeroplanes listed in Harbin Aircraft Manufacturing Corporation Service Bulletin (SB) Y12-76-0036 dated 3 August 1992. This directive is issued by the delegate of the Civil Aviation Safety Authority (CASA) under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 (CAR 1998). The purpose of the AD is to ensure the safety of the aircraft by mandating modifications to the central control pedestal to prevent the inadvertent operation of the reverse locking device at idle, which could lead to the power lever entering reverse. The requirement stipulates that if the modification has not already been performed, it must be carried out in accordance with SB Y12-76-0036 and in conjunction with the modification to the flap motor reducer as specified in SB Y12-27-0035 and AD/Y12/10. This directive becomes effective on 20 March 2003, with a compliance deadline set for 30 June 2003. It is applicable throughout the Commonwealth of Australia and is enforced by the CASA, highlighting the national scope of this regulatory action.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, contains a detailed Airworthiness Directive (AD) aimed at ensuring the safety of Harbin Y12 Series aeroplanes. According to section 39.1 (1) of the Civil Aviation Regulations, the AD mandates that certain actions be taken to correct an identified unsafe condition. For the Harbin Y12 Series aeroplanes, the AD requires that the central control pedestal be modified in accordance with Service Bulletin Y12-76-0036. This modification should be carried out in conjunction with another modification specified in Service Bulletin Y12-27-0035, as referenced in AD/Y12/10. These modifications are intended to rectify issues that could lead to the inadvertent operation of the reverse locking device at idle, potentially causing the power lever to enter reverse.
The AD imposes specific obligations on the parties and entities it governs. The key obligation is the timely modification of the central control pedestal of the Harbin Y12 Series aeroplanes, as outlined in the requirement section of the AD. The modifications must be completed before the compliance deadline, which is 30 June 2003. Additionally, the AD specifies that the modification should be done in conjunction with another modification to the flap motor reducer, ensuring that both safety concerns are addressed simultaneously.
Failure to comply with the AD could result in serious consequences. The AD does not explicitly outline specific offences or penalties within the text, but non-compliance with airworthiness directives is generally considered a serious violation under the Civil Aviation Regulations. In general, non-compliance could lead to enforcement actions by the Civil Aviation Safety Authority, including the grounding of the aircraft until the required modifications are completed. The severity of the penalties may vary depending on the circumstances and the extent of non-compliance, but they can include significant financial penalties, operational restrictions, or even the revocation of the aircraft's certificate of airworthiness.
