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/Y12/5 Aileron Spar Balance Support 3/2003
Applicability: All Model Y12 aircraft.
Requirement: Action in accordance with Harbin Aircraft Service Bulletin No. Y12-57-0056R1.
Note: China CAAC AD CAD95-Y012-01R1 refers.
Compliance: Unless the requirements of this Directive have been previously accomplished, accomplish the following:
- For aircraft that have accumulated less than 2,000 flight hours as of 20 March 2003, inspect in accordance with the Requirement document. If defects as described in the Requirement document are evident, incorporate the reinforcement in accordance with the Requirement document before further flight.
2. For aircraft that have accumulated more than 2,000 flight hours as of 20 March 2003, incorporate the reinforcement in accordance with the Requirement document before 30 March 2003.

Overview
The Civil Aviation Regulations 1998 (CAR 1998) were enacted to establish a comprehensive framework for ensuring the safety of civil aviation in Australia. The regulations cover a wide range of areas including the airworthiness of aircraft, licensing of personnel, and operational standards. The problem this legislation was introduced to address was the need for a unified and robust set of rules and standards to govern civil aviation safety in the country, ensuring that all operations meet high safety standards to protect passengers, crew, and the general public. The CAR 1998 is administered by the Civil Aviation Safety Authority (CASA), which is the body responsible for enforcing these regulations. The policy objective behind the regulations is to maintain and enhance the safety of civil aviation through rigorous oversight, clear standards, and effective enforcement mechanisms.
Scope and Application
The Airworthiness Directive AD/Y12/5 issued by the Civil Aviation Safety Authority (CASA) pertains to all Harbin Y12 Series aeroplanes, as specified in the Civil Aviation Regulations 1998. This directive applies to these aircraft to ensure safety standards are met by mandating specific actions to correct identified unsafe conditions. The directive applies regardless of the aircraft's registration or operator, focusing solely on the condition and accumulated flight hours of the aircraft. CASA's directive is binding for all Model Y12 aircraft within the Commonwealth of Australia, with a specific compliance timeframe based on the aircraft's flight hours as of 20 March 2003. The directive allows for flexibility in compliance based on accumulated flight hours, with different actions required for aircraft with less than 2,000 flight hours and those with more than 2,000 flight hours as of the directive's effective date. This AD, published in the Commonwealth of Australia Gazette on 26 February 2003, does not specify any exclusions or exemptions but requires adherence to the detailed instructions provided by Harbin Aircraft Service Bulletin No. Y12-57-0056R1.
Key Provisions
The Civil Aviation Regulations 1998, specifically under PART 39 - 105, establishes a framework for issuing Airworthiness Directives (ADs) to ensure the safety of aircraft and aeronautical products. The main operative sections (such as sections 39.1 and 39.1(1)) empower the Civil Aviation Safety Authority (CASA) to issue ADs, which mandate specific actions to address safety issues. For example, the Harbin Y12 Series Aeroplanes AD/Y12/5, issued under section 39.1(1), requires actions to reinforce the aileron spar balance support to prevent unsafe conditions. This AD applies to all Model Y12 aircraft and outlines specific requirements and compliance timelines.
The AD imposes several obligations on the entities it governs. Primarily, it mandates that all Model Y12 aircraft undergo specific inspections and modifications to the aileron spar balance support, as detailed in Harbin Aircraft Service Bulletin No. Y2-57-0056R1. For aircraft with less than 2,000 flight hours as of 20 March 2003, inspections must be conducted to identify any defects, followed by necessary reinforcements if defects are found. For aircraft with more than 2,000 flight hours as of the same date, the reinforcement must be incorporated before 30 March 2003. These obligations are clearly set out in the requirement section of the AD.
Failure to comply with the Airworthiness Directive may result in significant consequences. While the specific provisions regarding penalties or legal consequences for non-compliance are not detailed within the AD itself, it is understood that non-compliance with CASA regulations can lead to enforcement actions. Such actions could include administrative penalties, grounding of the aircraft, or even criminal charges in severe cases, depending on the nature and extent of the violation. The exact penalties would be determined under the broader framework of the Civil Aviation Act 1988 and associated regulations.
