AD/DH114/5 - Fuel Tank Filler - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, were introduced to provide comprehensive regulation of civil aviation in Australia, ensuring safety, efficiency, and environmental protection within the industry. Within this regulatory framework, Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives specifically addresses the requirements for maintaining the airworthiness of aircraft, ensuring they meet safety standards. One such directive, AD/DH114/5, pertains to the modification of fuel tank fillers for DH114 (Heron) Series aeroplanes, aiming to enhance safety by addressing specific issues related to the aircraft's fuel system. This directive applies to all Series 1B aeroplanes not previously modified in accordance with DH Heron Mod. 219 and requires compliance with either DH Heron Mod. No. 311 and DH Heron Mod. 350 or 352, or ANO 105.1.14.17.5.6, with adherence mandated before 1 September 1955. The overarching policy objective of these regulations is to maintain the highest possible standards of safety and airworthiness in Australia's civil aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, under the authority of the Commonwealth of Australia, govern various aspects of civil aviation, including safety standards and operational requirements. Specifically, Part 39 - 105 of the Civil Aviation Regulations pertains to the Airworthiness Directives for various aircraft, with AD/DH114/5 focusing on the modification of fuel tank fillers for the DH114 (Heron) Series Aeroplanes. This directive applies to all Series 1B DH114 aircraft that have not been modified in accordance with DH Heron Modification 219. Compliance with the directive requires adherence to either DH Heron Modifications 311 and 350 or 352, or to the requirements stipulated in the Airworthiness Notice (ANO) 105.1.14.17.5.6, and must be achieved before 1 September 1955. The regulations ensure that all affected aircraft meet the specified safety standards, thereby enhancing the overall safety and reliability of the civil aviation system within Australia.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, address the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives. One pertinent directive is AD/DH114/5, which pertains to the modification of the fuel tank filler for DH114 (Heron) Series Aeroplanes (section 105.1.14.17.5.6). This directive applies to all Series 1B DH114 aircraft that have not been modified in accordance with DH Heron Mod. 219. The required modifications are detailed in DH Heron Mod. No. 311 and DH Heron Mod. 350 or 352, or alternatively, they must comply with ANO 105.1.14.17.5.6. Compliance with this directive must be achieved before 1 September 1995. The primary obligation under this directive is that all affected aircraft must undergo the specified modifications to their fuel tank filler systems. This ensures that the aircraft meet the necessary safety standards set by CASA. The modifications may include specific structural changes, installation of particular components, or other technical adjustments to enhance the safety and reliability of the fuel tank filler system. The directive is clear that these modifications must be completed before the specified compliance date to avoid any regulatory issues. Failure to comply with the AD/DH114/5 directive can result in significant consequences. Under the Civil Aviation Regulations 1998, non-compliance with an Airworthiness Directive is an offence. The penalties for such breaches can be substantial, including potential criminal charges against the aircraft owner or operator. The maximum penalties for these offences are outlined in the regulations, which may include fines and, in severe cases, imprisonment. Additionally, CASA may impose administrative penalties or take enforcement actions such as grounding the aircraft until the required modifications are completed. It is crucial for operators and owners of DH114 Series 1B aircraft to ensure that they are aware of and comply with the requirements of AD/DH114/5. This includes staying updated with any changes or additional directives issued by CASA. Non-compliance not only risks legal repercussions but also poses significant safety hazards, potentially endangering the aircraft, its occupants, and other airspace users. Therefore, adherence to these regulations is essential to maintaining the safety and airworthiness of the aircraft in question.
