Overview
The Civil Aviation Regulations 1998, amended by the Civil Aviation Amendment (Enhancing Aviation Safety) Instrument 2006, address the need for ensuring the safety and airworthiness of aircraft operating in Australian airspace. Enacted by the Australian Parliament, this regulation specifically targets the maintenance and operational standards of aircraft, including the DHC-3 Otter series aeroplanes, to prevent any potential safety risks. The policy objective behind these amendments is to enhance the overall safety of civil aviation by ensuring compliance with international standards and directives, such as the requirement for the main undercarriage compression strut in DHC-3 Otter aeroplanes, as specified in the relevant airworthiness directives.
Scope and Application
The Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically Part 39 - 105, pertains to the airworthiness of DHC-3 (Otter) Series Aeroplanes. This directive applies to all models with serial numbers ranging from 1 to 40, necessitating immediate compliance with De H Canada TNS Otter No 23. The requirement is for actions to be taken as outlined in the specified technical notice, referencing Canadian AD 54-4, with compliance mandated forthwith. The regulation's reach is national, overseen by the Commonwealth of Australia, and it extends its authority to ensure that all applicable aircraft maintain their airworthiness according to the stipulated technical standards. This directive does not specify exclusions, exemptions, or thresholds but relies on the enforcement of subordinate instruments to ensure thorough application and compliance across the designated aircraft models.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105 (Subpart C, Item 1), provides a schedule of airworthiness directives specifically targeting the DHC-3 (Otter) series aeroplanes. Under this schedule, AD/DHC-3/3 focuses on the main undercarriage compression strut of all models with serial numbers ranging from 1 to 40. The requirement is to comply with the technical directive issued by De Havilland Canada, specifically De Havilland Canada Technical Notice No. 23, which is referenced in Canadian AD 54-4. This directive mandates that compliance must be achieved forthwith, indicating an immediate requirement for action.
Entities governed by these regulations must ensure that the main undercarriage compression strut of the specified Otter models is addressed in accordance with the detailed instructions provided in the referenced technical notices. This involves following specific maintenance, inspection, or repair procedures as outlined by De Havilland Canada. Compliance involves conducting the necessary actions without delay to maintain the airworthiness of the aircraft in question.
Failure to comply with the airworthiness directives can lead to severe consequences. The Civil Aviation Safety Authority (CASA) enforces these regulations rigorously, and non-compliance can result in enforcement actions. Such actions may include the grounding of the affected aircraft, fines, or other civil penalties. Additionally, individuals or companies responsible for the aircraft may face criminal charges if the breach is deemed serious enough, leading to potential imprisonment or substantial fines. It is crucial for operators and maintenance personnel to understand and adhere to these directives to avoid any legal repercussions.
