AD/DHC-3/21 - Rudder Pedal Support

Overview

The Civil Aviation Regulations 1998, which were enacted by the Australian Parliament, form part of the legislative framework governing civil aviation in Australia. One of the components of this regulatory framework is Part 39 - 105, which pertains to airworthiness directives issued by the Civil Aviation Safety Authority. This part specifically addresses the maintenance and operational standards required for various aircraft models, including the DHC-3 (Otter) series aeroplanes. The legislation aims to ensure that all civil aircraft operating in Australia meet stringent safety standards to protect passengers, crew, and the general public. The policy objective underlying these regulations is to maintain the highest possible level of safety in civil aviation by mandating specific maintenance actions and compliance timelines, as exemplified by Airworthiness Directive AD/DHC-3/21 concerning the rudder pedal support in DHC-3 (Otter) series aeroplanes.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all DHC-3 (Otter) series aeroplanes within the jurisdiction of the Commonwealth of Australia. This legislative instrument mandates compliance with Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA), including AD/DHC-3/21, which pertains to the rudder pedal support. This regulation encompasses all models of the Otter series, necessitating immediate action in accordance with the technical directive issued by de Havilland Canada, TNS Otter No. 96. The directive applies across the national jurisdiction, ensuring that all operators and owners of these aircraft must adhere to the specified compliance requirements without exception. The application of these regulations may be further defined or extended through subordinate instruments issued by CASA, providing additional details or specific conditions of compliance.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105 (section 39.105), pertain to airworthiness directives concerning various aircraft types, including the DHC-3 (Otter) series aeroplanes. One such directive, AD/DHC-3/21, concerns the rudder pedal support and applies to all models of the DHC-3 (Otter) series aeroplanes (section 39.105(1)). This directive mandates that the action taken must comply with De H Canada TNS Otter No. 96, which outlines the specific requirements and procedures for ensuring the rudder pedal support is properly installed and maintained (section 39.105(2)). The obligations imposed by this directive are clear and straightforward. Operators of DHC-3 (Otter) series aeroplanes must ensure that their aircraft comply with the requirements of AD/DHC-3/21 without delay. This means they must follow the guidance provided in De H Canada TNS Otter No. 96, which includes detailed instructions on the inspection, repair, or replacement of the rudder pedal support as necessary (section 39.105(3)). Failure to comply with these airworthiness directives can result in serious safety risks, potentially leading to operational issues or even accidents. In the event of non-compliance with the airworthiness directive, there are significant consequences. Under section 39.105(4) of the Civil Aviation Regulations 1998, non-compliance can lead to both civil and criminal penalties. For example, operators who fail to adhere to the airworthiness directive may face fines of up to $21,000 per non-compliant flight or up to $105,000 per non-compliant aircraft, depending on the severity of the breach. Additionally, if the non-compliance results in an accident or incident, the penalties can be much more severe, potentially including imprisonment for directors or responsible officers of the operating entity. This underscores the importance of strict adherence to the airworthiness directives to ensure the safety of all passengers and crew aboard DHC-3 (Otter) series aeroplanes.
