AD/DHC-3/1 - Rudder Quadrant, Rudder Pedal Linkage, Tail Wheel Assembly and Rear Fuselage

Overview

The Civil Aviation Regulations 1998, amended through legislative instrument F2006B09057, specifically address safety issues concerning the DHC-3 (Otter) series aeroplanes, targeting problems related to the rudder quadrant, rudder pedal linkage, NK tail wheel assembly, and rear fuselage. Enacted by the Parliament of the Commonwealth of Australia, the policy objective of these regulations is to ensure that civil aviation operations maintain the highest standards of safety. This legislative instrument was introduced to fill gaps in existing aviation safety protocols, ensuring that specific components of the DHC-3 Otter are regularly inspected and maintained to prevent potential failures that could compromise flight safety. The requirement for compliance is immediate, underscoring the importance of these safety directives in the operational standards of 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, applies to the DHC-3 (Otter) series aeroplanes, ensuring that specific components such as the rudder quadrant, rudder pedal linkage, NK tail wheel assembly, and rear fuselage adhere to stringent safety standards. This regulation is applicable to all persons or entities operating these aircraft within Australia, thereby impacting various aviation industries including private flight operations, charter services, and any other entities involved in the maintenance and operation of DHC-3 Otter series aeroplanes. The scope of the regulation is national, and it mandates compliance with the actions outlined in De H Canada TNS Otter Nos 3 or 4, 6 and 9, as well as referencing Canadian AD 53-16. The requirement for compliance is immediate, emphasising the urgency and critical nature of the safety measures outlined. While the regulation sets clear directives, the detailed requirements and specific compliance actions are elaborated in the associated requirement document.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, pertain to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for DHC-3 (Otter) series aeroplanes. Section 39-105 AD/DHC-3/1 outlines the specific requirements for the rudder quadrant, rudder pedal linkage, NK tail wheel assembly, and the rear fuselage. This directive mandates actions in accordance with the De H Canada Technical Orders Nos 3 or 4, 6, and 9, with a note of reference to Canadian AD 53-16. The key provision of section 39-105 AD/DHC-3/1 requires compliance with specified technical orders and directives. This means that the aeroplanes must be maintained and modified in accordance with the detailed instructions provided by these documents. It is essential for operators and owners of DHC-3 (Otter) series aeroplanes to ensure that all actions are taken as directed by these technical orders to maintain the airworthiness of the aircraft. Compliance must be achieved forthwith, which means immediately upon the issuance of the directive. Entities governed by this regulation must adhere to the requirements specified by CASA. This includes conducting the necessary inspections, modifications, or repairs to the rudder quadrant, rudder pedal linkage, NK tail wheel assembly, and the rear fuselage as detailed in the referenced technical orders. Operators are required to maintain records of all actions taken to ensure compliance with the directive, and to demonstrate that these actions have been completed in a timely manner. Failure to comply with the airworthiness directive can result in severe consequences. Under the Civil Aviation Act 1988, non-compliance with CASA directives can be considered an offence. Penalties for such breaches can include substantial fines and, in some cases, criminal charges against individuals responsible for the non-compliance. The maximum penalties for non-compliance can vary but are designed to ensure the highest standards of aviation safety are maintained across all operations.
