Overview
The Civil Aviation Regulations 1998, specifically Part 39, introduced measures to ensure the safety of civil aviation within Australia. One such measure is Airworthiness Directive (AD) AD/SD3-60/52 Amdt 2, which was enacted in response to reported in-service failures of elevator trim control cables in SD3-60 aircraft. The directive was issued by the Civil Aviation Safety Authority (CASA) to address these safety concerns and ensure compliance with the necessary maintenance standards. The AD requires the inspection and replacement of specific elevator trim control cables in SD3-60 aircraft to mitigate the risk of in-service failures, reflecting the policy objective of maintaining high safety standards in civil aviation.
Scope and Application
The Airworthiness Directive (AD) AD/SD3-60/52 Amdt 2 issued under the Civil Aviation Regulations 1998 specifically applies to all SD3-60 series aircraft. This directive mandates actions necessary to address an identified unsafe condition concerning the elevator trim control cables. The requirement necessitates that an inspection be conducted before 25 March 2000 and that, upon the accumulation of 10,000 flights, all 7x7 type elevator trim control cables be replaced with 7x19 type cables as outlined in the Requirement document. This directive is issued by the Civil Aviation Safety Authority (CASA) and becomes effective on 7 September 2000, as published in the Commonwealth of Australia Gazette on 9 August 2000. The AD remains in effect nationwide, ensuring compliance across all relevant aircraft within the Australian jurisdiction.
Key Provisions
The main operative sections of this Airworthiness Directive (AD) are the applicability, requirement, and compliance sections. The applicability section (para. 1) specifies that the AD applies to all SD3-60 aircraft. The requirement section (para. 2) mandates that the action outlined in the directive must be taken in accordance with the instructions provided in the directive. Specifically, the directive requires that elevator trim control cables are inspected before 25 March 2000 and, upon the accumulation of 10,000 flights, replaced with 7x19 type cables, as listed in the requirement document. The compliance section (para. 3) outlines the timeline for these actions and notes that the compliance times of the previous issue of this directive remain unchanged by this amendment, which becomes effective on 7 September 2000.
The obligations and requirements imposed by this AD are quite specific. All owners and operators of SD3-60 aircraft must ensure that the elevator trim control cables are inspected before 25 March 2000. Furthermore, upon the aircraft reaching 10,000 flights, the specified 7x7 type elevator trim control cables must be replaced with 7x19 type cables, as detailed in the requirement document. These actions must be carried out in accordance with the instructions provided within the AD, ensuring that the safety standards are met and maintained.
Any breach of the obligations set out in this AD could result in severe consequences. While the specific penalties for non-compliance are not detailed in the AD, non-compliance with ADs can lead to severe civil and criminal penalties under the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998. The penalties can include fines and imprisonment, reflecting the seriousness with which the Civil Aviation Safety Authority (CASA) treats non-compliance with safety directives. Additionally, failure to adhere to these requirements could lead to the grounding of the aircraft, impacting operations and potentially leading to further safety issues.
