AD/DHC-3/15 - Engine Driven Fuel Pump

Overview

The Civil Aviation Regulations 1998, amended by the Legislative instrument F2006B09063, focus on ensuring the airworthiness of aircraft, specifically addressing safety directives for certain aircraft models. This particular legislative instrument pertains to the DHC-3 (Otter) series aeroplanes, aiming to resolve safety issues associated with engine-driven fuel pumps. The enactment by the Commonwealth of Australia through the Civil Aviation Safety Authority (CASA) targets the reliability and safety of fuel systems in these aeroplanes. The policy objective is to mandate compliance with specific directives to prevent potential operational failures, thereby ensuring the safety and efficiency of air travel. The urgency of compliance as stipulated in the regulations underscores the critical nature of the addressed safety concerns.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives, governs the airworthiness of DHC-3 (Otter) series aeroplanes fitted with Thompson TFD-900-3 or TFD-900-1 fuel pumps. This regulation applies to all models of these aircraft that are registered in Australia and are operated under the jurisdiction of CASA, ensuring compliance with safety directives set forth by De H Canada. The requirement mandates immediate action in accordance with De H Canada Engineering Bulletin "O" No 52, referencing Canadian Airworthiness Directive 58-11, thereby establishing a clear and immediate obligation for compliance. The scope of this legislation encompasses all operators and owners of DHC-3 Otter aircraft within Australia that are equipped with the specified Thompson fuel pumps. The directive applies to both private and commercial operators, extending its reach to any individual or entity that maintains or operates these aircraft. The regulation's geographic and jurisdictional reach is confined to the Commonwealth of Australia, as it falls under the purview of CASA. The directive does not explicitly state any exclusions, exemptions, or thresholds, implying a broad application to all affected aircraft. The enforcement and detailed implementation of this directive may be further extended or refined through subordinate instruments issued by CASA, ensuring adherence to safety standards and operational compliance.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically AD/DHC-3/15, pertain to the engine-driven fuel pump of DHC-3 (Otter) Series aeroplanes fitted with Thompson TFD-900-3 or TFD-900-1 fuel pumps. Section 105 of Part 39 requires compliance with the De H Canada EB “O” No 52 directive, which mandates actions to ensure the airworthiness of these aircraft components. Additionally, the note referencing Canadian AD 58-11 suggests that there is related prior action or guidance to consider. The compliance requirement is immediate, necessitating that all specified actions be undertaken forthwith to maintain safety standards. The obligations imposed by this regulation are straightforward but critical. Operators and maintainers of DHC-3 (Otter) Series aeroplanes must ensure that the engine-driven fuel pump is assessed and modified in accordance with the specified directive. This involves following the detailed instructions provided by De H Canada to verify and, if necessary, replace or repair the fuel pump to prevent potential safety hazards. Compliance must be achieved without delay, ensuring that the aircraft remains airworthy and safe for operation. Breaches of these regulations can lead to serious consequences. Under the Civil Aviation Act 1988, failure to comply with airworthiness directives can result in both civil and criminal penalties. Civil penalties may include fines up to a substantial amount, as outlined in the regulations. Additionally, criminal penalties may be imposed for more severe breaches, which can lead to imprisonment. The exact penalties can vary based on the severity of the breach and the discretion of the court, but they are designed to ensure strict adherence to safety standards. It is crucial for all parties involved to understand and comply with these requirements to avoid such repercussions.
