Overview

The Civil Aviation Safety Regulations 1998 (CASR 1998) were enacted to ensure the safety of civil aviation in Australia, providing a regulatory framework to manage the safety risks associated with civil aviation operations. The regulations were introduced to address the need for a comprehensive and consistent set of safety standards across the industry. Enacted by the Parliament of the Commonwealth of Australia, the CASR 1998 aim to ensure that all civil aviation activities in Australia meet the highest possible safety standards, thereby protecting the public and maintaining the integrity of the aviation industry. The regulations are administered by the Civil Aviation Safety Authority (CASA), which has the responsibility to enforce compliance and issue directives to address any identified safety issues. This particular Airworthiness Directive under CASR 1998 is intended to rectify an unsafe condition discovered in certain Eagle X-TS series aeroplanes, specifically addressing the issue of cracking on the main undercarriage attach bracket caused by a missing weld.

Scope and Application

The Civil Aviation Safety Regulations 1998, specifically under Part 39 - 105, mandates the creation of Airworthiness Directives (ADs) to address identified safety issues in civil aviation. The ADs are issued by a delegate of the Civil Aviation Safety Authority (CASA), who determines the necessary actions to correct unsafe conditions. This particular AD/X-TS/6 pertains to Eagle X-TS Series Aeroplanes, including models X-TS, X-TS 150, and 150B. The directive requires inspections to be conducted in accordance with Eagle Aircraft Service Bulletin 1123, or any later revisions approved by the Malaysia Department of Civil Aviation (DCA). If the adjoining plates on the undercarriage attach bracket are not welded, the attach bracket must be replaced before further flight. This directive applies to all affected aircraft and must be complied with before any further flight after 18 August 2004. The AD came into effect on 18 August 2004, as published in the Commonwealth of Australia Gazette. This directive highlights the regulatory approach to ensuring the safety of aircraft by mandating specific actions and inspections to address identified structural issues.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CASR 1998) under Part 39 - 105, issued an Airworthiness Directive (AD) concerning the Eagle X-TS series aeroplanes, specifically AD/X-TS/6, which addresses the main undercarriage attach bracket. This directive applies to all Model X-TS, X-TS 150, and 150B aircraft (section 1). The directive mandates that an inspection be conducted in accordance with Eagle Aircraft Service Bulletin 1123, as originally issued or any later revisions approved by the Malaysia DCA. If the adjoining plates on the undercarriage attach bracket are found not to be welded, the attach bracket must be replaced before any further flight (section 2). This directive references Malaysia DCA CAM AD 001-08-2004 and specifies that compliance must occur before any further flight after 18 August 2004 (section 3). The directive became effective on 18 August 2004. The obligations imposed by this AD on the operators of the affected aircraft include ensuring that all inspections and necessary repairs are conducted as specified in the directive. This includes adhering to the procedures outlined in the Eagle Aircraft Service Bulletin 1123 and any subsequent revisions approved by the Malaysia DCA. Operators must ensure that the inspection is performed before any further flight, and if the undercarriage attach bracket is found to lack the required welds, it must be replaced immediately. The directive underscores the importance of addressing this specific issue to prevent the unsafe condition that could arise from unwelded adjoining plates on the undercarriage attach bracket. Failure to comply with this Airworthiness Directive can result in severe consequences. Non-compliance may lead to the unsafe condition not being rectified, potentially resulting in catastrophic failure of the undercarriage attach bracket during flight. Such failure could endanger the safety of the aircraft, passengers, and crew. While the Civil Aviation Safety Regulations 1998 do not explicitly state penalties for non-compliance with Airworthiness Directives, failure to adhere to such directives can result in enforcement actions by the Civil Aviation Safety Authority (CASA), including grounding of the aircraft, fines, and potential prosecution. The seriousness of these consequences highlights the imperative for operators to comply fully and promptly with the directive.
