AD/DHA-3/2 - Wing Assembly - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, represent a comprehensive framework designed to ensure the safety and efficiency of civil aviation operations within the country. Specifically, Part 39 of these regulations pertains to the oversight and regulation of aircraft airworthiness, addressing issues and gaps related to the maintenance, inspection, and operational safety of aircraft. The policy objective underpinning these regulations is to provide a robust system for ensuring that all civil aircraft meet stringent safety standards, thereby protecting the public and fostering confidence in the aviation industry. One specific legislative instrument under this framework is the DHA-3 (Drover) Series Aeroplanes Airworthiness Directive, which was introduced to address safety concerns related to the wing assembly of these aircraft models. The directive mandates modifications to the wing assembly to ensure compliance with airworthiness standards, as outlined in documents such as DH TNS CT(A3) No. 24 or 38, and CT(A3) Nos. 2 and 25, or ANO 105.1.14.14.5.3. Compliance with these directives is required forthwith, reflecting the urgency and importance of the safety measures being implemented.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives (ADs) concerning the Drover series aeroplanes, such as the DHA-3, mandating modifications to the wing assembly as outlined in AD/DHA-3/2. This regulation applies to all models of the DHA-3 aeroplanes, demanding immediate compliance with the directives as stipulated. The relevant documents referenced include DH TNS CT(A3) No. 24 or 38, and CT(A3) Nos. 2 and 25, as well as ANO 105.1.14.14.5.3, which specify the technical requirements and procedures to be adhered to. The scope of this legislation is comprehensive within the Commonwealth of Australia, ensuring that all operators and entities involved with the DHA-3 aeroplanes must comply with the airworthiness directives issued by CASA. The regulation does not explicitly state exclusions or exemptions, implying a broad application unless otherwise specified through subordinate instruments.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, include a schedule of airworthiness directives that govern various modifications and maintenance requirements for certain aircraft models. One such directive, AD/DHA-3/2, pertains to the wing assembly of the DHA-3 (Drover) Series Aeroplanes (11/52). This directive applies to all models of the DHA-3 series (11/52) and mandates compliance with specified technical documents. The relevant documents include DH TNS CT(A3) No. 24 or 38, and CT(A3) Nos. 2 and 25, or ANO 105.1.14.14.5.3. The directive requires that compliance with these modifications must occur forthwith. The obligations imposed by AD/DHA-3/2 on the parties governed by these regulations are primarily concerned with ensuring the airworthiness of the DHA-3 (Drover) Series Aeroplanes. Operators and maintenance personnel must adhere to the specified technical standards and procedures outlined in the referenced documents. This involves inspecting the wing assembly and implementing any necessary modifications to meet the safety standards set forth by the Civil Aviation Safety Authority. The regulations necessitate that these modifications be carried out without delay to maintain the aircraft's airworthiness certification. Failure to comply with the provisions of AD/DHA-3/2 can result in various civil and criminal consequences. The regulations outline specific offences related to non-compliance with airworthiness directives. These can include administrative penalties for operators who fail to implement the required modifications promptly. In more severe cases, non-compliance may result in prosecution under civil or criminal law, with potential penalties that can include fines or imprisonment, depending on the severity of the breach and its impact on aviation safety. The specific penalties are detailed within the broader regulatory framework of the Civil Aviation Act 1988 and associated regulations, which provide the legal basis for enforcing compliance with airworthiness directives.
