AD/DHC-1/2 - Engine Mount Pick-Up Points - Modification

Overview

The Civil Aviation Regulations 1998, amended by the legislative instrument F2006B09003, is a critical piece of Australian legislation designed to enhance the safety of civil aviation through the issuance of Airworthiness Directives. Enacted by the Commonwealth of Australia, these regulations aim to fill the gap in ensuring that specific aircraft models adhere to safety standards. This particular legislative instrument targets the De Havilland DHC-1 (Chipmunk) Series Aeroplanes and addresses the need to modify the engine mount pick-up points to ensure continued compliance with safety standards. The objective of the directive is to mandate compliance without delay, ensuring that all affected aircraft meet the required safety criteria as outlined in the relevant documents such as DH TNS CT(C1) No. 63 or ANO 105.1.14.15.5.2.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to airworthiness directives issued by the Civil Aviation Safety Authority (CASA). This particular legislation applies to all English production models of the De Havilland DHC-1 (Chipmunk) Series Aeroplanes, mandating modifications to the engine mount pick-up points as outlined in AD/DHC-1/2. The directive is to be adhered to immediately, as indicated by the "forthwith" compliance requirement. The regulations extend their reach to ensure the safety and airworthiness of these specific aircraft types within the Australian aviation sector. The legislation's application is further clarified through referenced documents such as DH TNS CT(C1) No. 63 and ANO 105.1.14.15.5.2, which provide additional technical and procedural guidance. This legislative instrument underscores the importance of continuous safety measures in the aviation industry, ensuring that specific aircraft meet stringent regulatory standards.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, establish the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives. Specifically, AD/DHC-1/2 pertains to the De Havilland DHC-1 (Chipmunk) Series Aeroplanes and requires modification to the engine mount pick-up points. This directive applies to all English production models of these aircraft (AD/DHC-1/2, 9/52). Compliance with this directive is mandated forthwith, ensuring that the specified modifications are carried out immediately (AD/DHC-1/2, 9/52). The obligations imposed by this directive require the owners or operators of the affected aircraft to undertake the necessary modifications to the engine mount pick-up points as outlined in the referenced documents. These documents include DH TNS CT(C1) No. 63 or ANO 105.1.14.15.5.2 (AD/DHC-1/2). It is imperative that these modifications are completed without delay to maintain the airworthiness of the aircraft, ensuring safety standards are met and potential risks are mitigated. Failure to comply with the airworthiness directive AD/DHC-1/2 can result in significant consequences. The Civil Aviation Regulations 1998 do not explicitly outline penalties for non-compliance in this particular directive, but generally, non-compliance with CASA directives can lead to enforcement actions. These may include fines, suspension or revocation of aircraft operating certificates, or other regulatory sanctions. The severity of the penalties can vary based on the nature and extent of the non-compliance, but the overarching goal is to enforce safety standards and protect public safety in civil aviation.
