Overview

The Civil Aviation Safety Regulations 1998 (CASR 1998) were enacted to establish a comprehensive regulatory framework governing the safety of civil aviation within Australia. These regulations were introduced to address the need for stringent safety standards and procedures to ensure the protection of passengers, crew, and the public from aviation-related hazards. Enacted by the Australian Parliament, the policy objective of these regulations is to maintain and enhance the safety of civil aviation operations through the implementation of rigorous safety standards and compliance requirements. One specific example of such regulatory measures is the Airworthiness Directive issued under Part 39 of the CASR 1998, which mandates corrective actions to address identified safety issues in specific aircraft models, ensuring continued airworthiness and operational safety.

Scope and Application

The Airworthiness Directive AD/A330/16 applies to all Airbus Industrie A330-201, -202, -203, -223, and -243 aircraft, with the exception of those that have incorporated Airbus Modification 48510 in production, or Airbus Service Bulletin A330-27-3101 in service. The AD mandates the modification of the three rudder servo-controls in accordance with Airbus Service Bulletin A330-27-3101 to rectify the issue of rudder servo-control failure due to fatigue, which can lead to a potentially critical situation, particularly when combined with an engine failure at take-off or during go-around. This requirement must be fulfilled by 30 June 2005, unless already accomplished. The directive becomes effective from 15 May 2003. The AD is issued under the authority of the Civil Aviation Safety Regulations 1998, specifically subregulation 39.1(1), and extends to the entire Commonwealth of Australia. The regulation's scope is further extended and defined through subordinate instruments as necessary, ensuring compliance with the safety directives for the specified aircraft models.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CASR), specifically under Part 39, section 105, outline the procedures for Airworthiness Directives (ADs). This particular AD (AD/A330/16) targets Airbus Industrie A330 Series aeroplanes, excluding those with specific modifications or service bulletins already incorporated. The AD mandates the modification of the three rudder servo-controls in accordance with Airbus Service Bulletin A330-27-3101 to address a critical safety issue identified during pre-flight checks. The directive is applicable to Model A330-201, -202, -203, -223, and -243 aircraft, except those that have already implemented Airbus Modification 48510 or Airbus Service Bulletin A330-27-3101. The requirement necessitates that the specified modifications be completed by 30 June 2005, ensuring the safety and airworthiness of the aircraft involved. The AD imposes several obligations on the operators and maintainers of the affected aircraft. Firstly, they must identify whether their aircraft fall within the applicability criteria of the AD. If they do, they must adhere to the requirement to modify the rudder servo-controls as specified. This involves following the instructions laid out in Airbus Service Bulletin A330-27-3101, which provides detailed steps and technical specifications for the modification process. Operators and maintainers must ensure that the modifications are completed before the specified deadline, which is 30 June 2005. Additionally, they are required to document and certify that the modifications have been performed correctly and that the aircraft are now compliant with the AD. Failure to comply with the AD can lead to significant consequences. Civil Aviation Safety Authority (CASA) may take enforcement actions against operators and maintainers who do not adhere to the directive's requirements. Such actions can include fines, penalties, or even grounding of the aircraft until the required modifications are completed. The severity of the consequences reflects the critical nature of the safety issue addressed by the AD, as the failure of rudder servo-controls could lead to a potentially critical situation, particularly in the event of an engine failure during critical phases of flight. The AD serves as a regulatory tool to ensure that all affected aircraft are brought to a safe standard of airworthiness, thereby protecting the public and maintaining the integrity of the aviation industry.
