COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
DHA-3 (Drover) Series Aeroplanes
AD/DHA-3/23 Flap Inner Link Attachment Brackets - Inspection 3/61
Applicability: All models except S/No. 5020. Document: DH TNS CT(A3) No. 115.
Compliance: At intervals not exceeding 12 months.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, provide a comprehensive framework for the regulation of civil aviation safety, including the implementation of Airworthiness Directives (ADs) to ensure the safety of aircraft operations. One such AD is AD/DHA-3/23, which applies to the DHA-3 (Drover) series aeroplanes, specifically addressing the need for regular inspection of flap inner link attachment brackets. This directive aims to mitigate potential risks associated with structural integrity and operational safety, ensuring that all models, except serial number 5020, comply with the specified inspection intervals not exceeding 12 months as outlined in the Department of Defence Technical Note (DH TNS CT(A3) No. 115). The objective is to maintain the airworthiness of these aircraft by preventing structural failures that could compromise flight safety.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all aircraft operators and maintenance personnel working on DHA-3 (Drover) series aeroplanes, excluding the model with serial number 5020. The regulations are enforced by the Civil Aviation Safety Authority (CASA) and have a national jurisdictional reach throughout Australia, including all states and territories. The primary focus of this legislation is to ensure the airworthiness of the specified aircraft models through the implementation of Airworthiness Directives. AD/DHA-3/23 mandates that the flap inner link attachment brackets undergo inspection at intervals not exceeding 12 months to maintain compliance with safety standards. This directive is supported by the document DH TNS CT(A3) No. 115, which provides detailed instructions and requirements for the inspections. The application of these regulations can be extended or clarified through subordinate instruments issued by CASA, ensuring that all relevant parties are fully aware of their obligations and the expected standards of compliance.
Key Provisions
The Civil Aviation Regulations 1998 (Cth), particularly under Part 39, specifically addresses the airworthiness of aircraft, including detailed requirements for certain types and models. Section 105 of this Part, pertaining to the Schedule of Airworthiness Directives, focuses on the DHA-3 (Drover) Series Aeroplanes. One notable directive within this section is AD/DHA-3/23, which mandates inspections of the flap inner link attachment brackets (Section 3/61). This directive applies to all models of the DHA-3 (Drover) Series Aeroplanes except for the model with serial number 5020. The directive is documented in DH TNS CT(A3) No. 115 and requires inspections at intervals not exceeding 12 months.
Compliance with AD/DHA-3/23 imposes specific obligations on the parties or entities governed by these regulations. Operators and owners of the DHA-3 (Drover) Series Aeroplanes must ensure that the flap inner link attachment brackets are inspected regularly. This inspection must be conducted at intervals not exceeding 12 months, as specified in the directive. Such inspections are critical to maintaining the airworthiness of the aircraft and ensuring that the structural integrity of the flap system is preserved. Failure to comply with these inspection intervals may result in non-compliance with the Civil Aviation Regulations, which could lead to serious operational and safety issues.
In the event of non-compliance with the AD/DHA-3/23 directive, there are potential legal and safety consequences. The Civil Aviation Regulations 1998 establish various offences and penalties for breaches of airworthiness directives. While the specific penalties are not detailed in the legislative text provided, it is known that non-compliance with airworthiness directives can result in significant penalties. These may include fines, suspension or revocation of aircraft certificates, and potential criminal charges. The severity of the penalties may depend on the nature and extent of the breach, as well as any resultant safety risks or incidents. Ensuring adherence to these directives is, therefore, crucial for maintaining the safety and legality of aviation operations.
