AD/SD3-30/13 Amdt 1 - Right and Left Drag Links - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA) under the oversight of the Australian Parliament, were enacted to ensure the safety and efficiency of civil aviation within Australia. One of the components of this extensive regulatory framework is Part 39, which includes Airworthiness Directives aimed at maintaining the airworthiness of aircraft. The specific legislative instrument F2006B06814 addresses a critical gap in ensuring the structural integrity and safety of certain model SD3-30 aeroplanes through mandatory inspection and modification procedures. This directive, which applies to aircraft with serial numbers SH3002 to SH3088, was introduced to address potential safety risks associated with the drag links of these aeroplanes, ensuring compliance with safety standards set forth by CASA. The policy objective of AD/SD3-30/13 Amendment 1 is to enhance the safety of civil aviation by imposing a requirement for regular inspections and, where necessary, modifications to the right and left drag links of specified SD3-30 aeroplanes. This directive mandates that inspections be carried out within 600 hours of time in service after 30 November 1982 and incorporates a radiographic technique to facilitate more accurate assessments. The directive is based on the technical bulletin issued by Shorts, SB No. SD3-53-48, Revision 1, ensuring that all relevant safety measures are adhered to in the maintenance and operation of these aircraft.

Scope and Application

The Civil Aviation Safety Authority's (CASA) Regulations under the Civil Aviation Act 1988 apply to all operators of model SD3-30 series aeroplanes with serial numbers ranging from SH3002 to SH3088. This specific legislation pertains to the inspection and modification of the right and left drag links, as outlined in the Shorts Service Bulletin No. SD3-53-48, Revision 1. Compliance with these regulations is mandatory unless the required inspections and modifications have already been completed. The directive necessitates that these actions be undertaken within 600 hours of time in service following 30 November 1982, ensuring the continued airworthiness and safety of the aircraft in question. The scope of this legislation is national, extending across all states and territories of Australia, with no stated exclusions or exemptions. The application is further defined through subordinate instruments which may provide additional guidance or clarification on the compliance requirements and procedures.

Key Provisions

The main operative sections of this legislation, specifically AD/SD3-30/13 Amendment 1, pertain to the inspection and modification of right and left drag links for Short SD3-30 series aeroplanes with serial numbers SH3002 to SH3088. This directive is governed under the Civil Aviation Regulations 1998 (CAR), Part 39, specifically in the schedule of airworthiness directives. According to Section 1 of this directive, the inspection and modification of the drag links must be carried out unless it has already been completed (Section 1). The compliance requirement stipulates that these actions must be taken within 600 hours of time in service after 30 November 1982 (Section 2). The directive references Shorts Service Bulletin No. SD3-53-48, Revision 1, as the document to be followed for the inspection and modification procedures. The obligations imposed by this Act are clear and specific. Operators and maintainers of the affected Short SD3-30 series aeroplanes are required to ensure that the right and left drag links are inspected and, if necessary, modified in accordance with the guidelines set out in Shorts SB No. SD3-53-48, Rev. 1. This involves not only the physical inspection and modification tasks but also the meticulous documentation of these processes to maintain compliance with the regulation. Additionally, the operators must ensure that these actions are completed within the specified timeframe of 600 hours of time in service following the date of 30 November 1982. Failure to adhere to these requirements can result in the aircraft being deemed non-airworthy, potentially leading to operational restrictions or grounding. Failure to comply with the provisions of AD/SD3-30/13 Amendment 1 can result in significant consequences. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives can lead to civil penalties. The maximum penalty for an individual can include fines up to $27,500 or imprisonment for up to 12 months, or both. For a corporation, the fines can reach up to $137,500. Additionally, the Civil Aviation Safety Authority (CASA) may take enforcement actions such as suspending or revoking airworthiness certificates, which would effectively ground the aircraft until the required actions are completed and verified. Furthermore, any resultant accidents or incidents caused by non-compliance could lead to more severe legal and financial repercussions, including potential criminal charges if gross negligence or willful misconduct is established.
