AD/DHC-2/7 - Aileron Differential Mount - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, provide a comprehensive framework for ensuring the safety and efficiency of civil aviation in the country. Among its various provisions, Part 39, specifically concerning airworthiness directives, addresses the need for continuous updates and modifications to aircraft to ensure ongoing compliance with safety standards. The legislative instrument F2006B09055, concerning the airworthiness directive for de Havilland Canada DHC-2 (Beaver) Series aeroplanes, exemplifies this commitment by mandating specific modifications to the aileron differential mount as outlined in the directive AD/DHC-2/7. This directive, based on de Havilland and Canada Engineering Bulletin Series "B" No. 28, was introduced to address specific safety concerns and ensure the continued airworthiness of these aircraft, aligning with the overarching policy objective of maintaining high safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, which pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, governs the airworthiness of DHC-2 (Beaver) Series Aeroplanes. This legislation applies to all models of DHC-2 aeroplanes, mandating compliance with the outlined airworthiness directives to ensure safety standards are met. The directive in question, AD/DHC-2/7, pertains to the modification of the aileron differential mount and requires immediate compliance as stipulated in De Havilland and Canada Engineering Bulletin Series "B" No. 28. This regulation is a Commonwealth enactment, thereby extending its jurisdictional reach across Australia, ensuring uniform safety standards are upheld in the civil aviation sector. The application of this directive is comprehensive, encompassing all operators and owners of DHC-2 (Beaver) Series Aeroplanes within the Australian jurisdiction. The regulation leaves no room for exclusions or exemptions, demanding that all affected aircraft meet the specified safety requirements without deviation. Additionally, the scope of this directive may be further detailed or expanded through subordinate instruments issued by CASA, ensuring that any subsequent modifications or clarifications are incorporated into the operational standards. This ensures that the safety and operational integrity of DHC-2 aeroplanes are consistently maintained across the nation.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, mandates the applicability of certain airworthiness directives to all models of DHC-2 (Beaver) Series aeroplanes, as outlined in AD/DHC-2/7. This directive pertains to a modification of the aileron differential mount (section 4/63). Compliance with these directives is required immediately upon notification, with adherence to the detailed instructions provided in De Havilland and Canada Engineering Bulletin Series "B" No. 28. The Act imposes clear obligations on aircraft owners and operators to ensure their aircraft meet the specified airworthiness standards. Under section 4/63, it is mandatory for all DHC-2 (Beaver) Series aeroplanes to undergo the specified modification of the aileron differential mount. This requirement ensures that the aircraft maintain safe operational standards and mitigates any potential risks associated with the identified issue. The compliance must be demonstrated forthwith, highlighting the urgency and importance of these safety measures. Failure to comply with the airworthiness directives stipulated in the Civil Aviation Regulations 1998 can lead to serious consequences. Section 4/63 outlines that non-compliance may result in civil or criminal penalties. The specific penalties for breaches of these directives are not detailed in the provided text, but generally, such breaches can result in fines, imprisonment, or both, depending on the severity of the non-compliance and its impact on aviation safety. The regulations underscore the critical nature of adhering to these directives to ensure the safety of all involved in civil aviation operations.
