Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, constitute a comprehensive regulatory framework aimed at ensuring the safety and efficiency of civil aviation operations within the country. Among its various provisions, Part 39 - 105 specifically pertains to the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives, which are critical in maintaining the airworthiness of aircraft. This legislative instrument addresses potential safety concerns by mandating specific actions to be taken by aircraft operators and other stakeholders. For instance, Airworthiness Directive AD/LEARJET/12 pertains to Gates Learjet 24 & 25 Series Aeroplanes, focusing on the replacement of control system stop bolts to mitigate potential risks. The overarching policy objective of these regulations is to enhance aviation safety by ensuring that aircraft meet the necessary standards and conditions for safe operation.
Scope and Application
The Civil Aviation Regulations 1998, under the authority of the Civil Aviation Safety Authority (CASA), mandate specific safety directives to ensure the airworthiness of aircraft operating within Australia. Specifically, Part 39 – 105, Schedule of Airworthiness Directives, governs the compliance requirements for Gates Learjet 24 and 25 Series aeroplanes. This directive applies to all Gates Learjet 24 aeroplanes with serial numbers (S/Nos) ranging from 24-100 to 24-304 and from 24-309 to 24-322, and all Gates Learjet 25 aeroplanes with S/Nos. from 25-003 to 25-197. The directive mandates that the control system stop bolts must be replaced within 300 hours of time in service after 31 October 1975, as outlined in Gates Learjet SB 23/24/25-266. The scope of the legislation is specifically tailored to ensure that these aircraft meet the required safety standards to operate within Australia’s airspace. The application is geographically confined to the Commonwealth of Australia, overseen by CASA, and does not extend beyond national borders. The regulations do not specify exclusions, exemptions, or thresholds within the text provided.
Key Provisions
The main sections of this legislative instrument concern the applicability and compliance requirements for the replacement of control system stop bolts in Gates Learjet 24 and 25 series aeroplanes (Section 9/75). Specifically, this Airworthiness Directive (AD) mandates that all Gates Learjet 24 aircraft with serial numbers (S/Nos.) ranging from 24-100 to 24-304 and from 24-309 to 24-322, and all Gates Learjet 25 aircraft with S/Nos. from 25-003 to 25-197 must comply with the directive (Section 9/75). The directive references Gates Learjet Service Bulletin 23/24/25-266 as the document containing the detailed instructions for compliance.
The obligations imposed by this Act on the parties or entities it governs include ensuring that the control system stop bolts are replaced within 300 hours of time in service after 31 October 1975. This is to maintain the safety and airworthiness of the aircraft in accordance with the specified service bulletin. Operators and owners of the affected aircraft must take immediate action to identify and address the issue to prevent any potential safety risks. Additionally, it is necessary for the operators to maintain records of compliance and ensure that any inspections or maintenance work is carried out by qualified personnel.
Failure to comply with the Airworthiness Directive may result in serious consequences. Civil Aviation Safety Authority (CASA) may take enforcement actions against non-compliance, which can include the suspension or revocation of the aircraft’s airworthiness certificate. This could prevent the aircraft from being operated until the required modifications are completed. Furthermore, any violation of the regulations could lead to civil penalties under the Civil Aviation Act 1988, which includes substantial fines. In the most severe cases, criminal charges may be filed against individuals responsible for the non-compliance, which could result in imprisonment. The exact penalties would depend on the severity and circumstances of the breach.
