AD/DHC-3/14 - Tailplane Fork Attachment Fitting

Overview

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, detail the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for DHC-3 (Otter) Series Aeroplanes. This legislation was enacted to ensure the ongoing airworthiness and safety of aircraft by imposing mandatory compliance with certain directives, thus addressing potential safety gaps in aircraft maintenance and operational standards. The objective of these regulations is to maintain high safety standards in civil aviation by requiring aircraft operators to adhere to specific maintenance and operational procedures as stipulated by CASA, ensuring the safety and reliability of air travel in Australia. These regulations are enforced by the Australian Parliament to safeguard public safety and support the efficient operation of the civil aviation sector. The specific Airworthiness Directive referenced here, AD/DHC-3/14, pertains to the tailplane fork attachment fitting of DHC-3 Otter Series aeroplanes, covering all models with serial numbers 2 to 253. The directive requires compliance with the specifications outlined in de Havilland Canada Engineering Bulletin "O" No 47, Issue 2, with reference to Canadian Airworthiness Directive 58-4. The directive mandates immediate action to address any identified issues, highlighting the importance of timely compliance to ensure aircraft safety and operational integrity. The regulations are designed to prevent potential hazards, thereby enhancing the overall safety of civil aviation operations within Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes a legislative instrument aimed at ensuring the airworthiness of DHC-3 (Otter) series aeroplanes. This particular legislative instrument, identified as AD/DHC-3/14, pertains to the tailplane fork attachment fitting of all DHC-3 models with serial numbers ranging from 2 to 253. The requirement is that the action must be taken in accordance with the De H Canada EB “O” No 47 Issue 2, with a reference to the Canadian AD 58-4. Compliance with these directives must be achieved forthwith, ensuring that the specified modifications are made without delay. This legislative instrument is part of a broader regulatory framework managed by the Civil Aviation Safety Authority, which enforces these directives across the Commonwealth of Australia to maintain safety standards in civil aviation.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, detail the requirements for maintaining the airworthiness of DHC-3 (Otter) Series Aeroplanes. The regulation in focus is AD/DHC-3/14, which addresses the tailplane fork attachment fitting for all models with serial numbers 2 to 253 (s. 39-105). This directive mandates actions to be taken in accordance with De H Canada EB “O” No 47 Issue 2 and notes that Canadian AD 58-4 is also relevant. The requirement is for compliance to be achieved forthwith, meaning immediately. Under this legislation, operators and owners of DHC-3 (Otter) Series Aeroplanes are obligated to ensure that the tailplane fork attachment fittings are addressed as per the specified directive. This involves adhering to the instructions outlined in De H Canada EB “O” No 47 Issue 2, which presumably includes inspection, maintenance, repair, or replacement of the specified parts to ensure they meet the required safety standards. The reference to Canadian AD 58-4 suggests that there may be additional or supplementary requirements or guidance that must be considered in conjunction with the primary directive. Failure to comply with the provisions set out in AD/DHC-3/14 could result in serious consequences. Although the specific penalties are not detailed in the extract, under the Civil Aviation Regulations, non-compliance with airworthiness directives can lead to severe civil and criminal penalties. Civil penalties can include fines and the potential grounding of the aircraft, which can have significant operational and financial repercussions for the operator. Criminal penalties may also apply, depending on the severity of the breach, potentially leading to prosecution and imprisonment for responsible individuals or entities. In conclusion, the key provisions of the Civil Aviation Regulations 1998, as outlined in AD/DHC-3/14, necessitate immediate action on the tailplane fork attachment fittings of specified DHC-3 (Otter) Series Aeroplanes. Operators and owners must adhere to the detailed instructions provided in De H Canada EB “O” No 47 Issue 2 and consider any supplementary guidance from Canadian AD 58-4. Breach of these requirements can result in significant civil and criminal penalties, underscoring the importance of prompt and thorough compliance.
