Overview
The Civil Aviation Regulations 1998 (Cth), specifically Part 39 - 105, were enacted to ensure the safe operation of civil aviation in Australia. This piece of legislation, amended through the legislative instrument F2006B09036, addresses the problem of improper rigging tensions on aileron control cables of DHC-2 (Beaver) Series aeroplanes, which could potentially compromise the safety and functionality of the aircraft. The Australian Parliament, through the Civil Aviation Authority, introduced this regulation to enhance the safety standards of airworthiness directives, ensuring that all applicable aircraft meet specific compliance criteria.
The policy objective of this regulation is to mandate a thorough inspection of the aileron control cables of DHC-2 Mk. II and Mk. III models within 100 hours of time in service after 30 November 1980, as per the manufacturer's Service Bulletin No. 2/27, Revision A. This directive aims to prevent the occurrence of incorrect rigging tensions that may lead to safety hazards, thereby maintaining high safety standards in civil aviation operations within Australia.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all DHC-2 Mk. II and Mk. III models of the de Havilland Canada Beaver Series Aeroplanes. This regulation mandates compliance with Airworthiness Directives established by the Civil Aviation Safety Authority. The directive AD/DHC-2/19, Amendment 1, focuses on the inspection of aileron control cables, as outlined in the De Havilland Aircraft of Canada Service Bulletin No. 2/27, Revision A. The requirement for compliance is to conduct the inspection within 100 hours of time in service after 30 November 1980, following the manufacturer's findings that incorrect rigging tensions had been applied to the non-flexible steel cables in some instances. This regulation operates under the Commonwealth of Australia, thereby having a national reach, and is not limited to specific states or territories. There are no stated exclusions or exemptions within the directive itself, although the application may be further detailed or modified through subordinate instruments or additional regulatory guidance.
Key Provisions
The main operative sections of the Civil Aviation Regulations 1998, specifically within Part 39 - 105, involve the requirements set forth in AD/DHC-2/19 Amendment 1, which mandates the inspection of aileron control cables on DHC-2 (Beaver) Series aeroplanes. This directive applies to all models DHC-2 Mk. II and Mk. III and is designed to ensure the airworthiness of these aircraft by addressing issues with the aileron control cables (section 10/80). The requirement for compliance is within 100 hours of time in service after 30 November 1980. The directive is based on a service bulletin issued by De Havilland Aircraft of Canada, SB No. 2/27, Revision A.
The obligations imposed by the Act on the relevant parties, including aircraft operators and maintenance organisations, are to conduct the specified inspection of the aileron control cables as per the requirements outlined in the service bulletin. This involves ensuring that the cables are correctly rigged to the appropriate tensions to avoid any potential issues that could compromise the safety of the aircraft. The operators must ensure that the inspections are carried out by appropriately certified personnel and that any deficiencies are rectified before the aircraft returns to service.
Breach of the requirements stipulated in the Civil Aviation Regulations can lead to significant consequences. Non-compliance with the airworthiness directives can result in the aircraft being deemed unairworthy, which may prevent it from operating until the issues are addressed. Additionally, from a regulatory standpoint, failure to adhere to these safety directives can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The penalties for such breaches can include fines and, in severe cases, criminal charges. The maximum penalties are not explicitly stated in the provided text, but they can be substantial, reflecting the critical importance of air safety and the need for stringent compliance with regulatory standards.
