AD/HS 125/46 - Fuel Filter De-Icing Pumps - Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, form a comprehensive regulatory framework designed to ensure the safety and efficiency of civil aviation within the country. One part of this extensive regulation, specifically Part 39 - 105, addresses Airworthiness Directives which are crucial for maintaining the safety standards of aircraft. The legislative instrument F2006B10485, which pertains to the British Aerospace BAe 125 Series Aeroplanes, is an example of such directives. This particular directive, AD/HS 125/46, was introduced to address issues related to the fuel filter de-icing pumps, aiming to replace them to enhance safety. The Civil Aviation Safety Authority is the enacting body responsible for ensuring compliance with these directives, reflecting the overarching policy objective of maintaining the highest safety standards in civil aviation. Compliance with these directives is mandatory and must be achieved within 100 hours of the aircraft's time in service after the specified date of 31 May 1977.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, mandate the application of Airworthiness Directives for specific aircraft models, including British Aerospace BAe 125 Series Aeroplanes. This legislative instrument applies to the owners and operators of these aircraft, ensuring adherence to specified maintenance requirements to ensure airworthiness. The regulation requires compliance within 100 hours of time in service after 31 May 1977, as outlined in the Hawker Siddeley SB 28-A63 requirement document. The directive pertains to the replacement of fuel filter de-icing pumps, which is critical for maintaining safety standards in aviation operations. The scope of this legislation is limited to the Commonwealth jurisdiction, impacting all operators and owners of the BAe 125 Series within Australia. There are no stated exclusions or exemptions within the directive itself, but further regulatory details may be specified in subordinate instruments.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes a Schedule of Airworthiness Directives which governs the maintenance and operational standards for various aircraft types. Within this schedule, AD/HS 125/46 pertains to the British Aerospace BAe 125 Series Aeroplanes and mandates the replacement of fuel filter de-icing pumps (Section 1). This directive applies as detailed in the requirement document Hawker Siddeley SB 28-A63, ensuring that the specified maintenance action is taken to maintain the airworthiness of these aircraft (Section 2). For the BAe 125 Series Aeroplanes, the primary requirement is that the fuel filter de-icing pumps must be replaced within 100 hours of time in service following the date of 31 May 1977 (Section 3). This directive ensures that the aircraft maintain their operational safety and reliability by adhering to the prescribed maintenance schedule. Compliance with these directives is critical for the continued airworthiness of the aircraft and is mandatory for operators of the BAe 125 Series (Section 4). Operators and owners of the British Aerospace BAe 125 Series Aeroplanes are obligated to ensure that the fuel filter de-icing pumps are replaced in accordance with the specified timeframe and requirements detailed in AD/HS 125/46 (Section 5). This includes maintaining accurate records of maintenance actions and ensuring that all personnel involved in the maintenance process are adequately trained and qualified to perform the required tasks (Section 6). Failure to comply with these directives can result in the aircraft being deemed unairworthy, potentially leading to grounding and further regulatory action (Section 7). Failure to comply with the airworthiness directive AD/HS 125/46 can result in significant consequences. The Civil Aviation Safety Authority has the authority to enforce compliance and may take action against operators or owners who do not adhere to the maintenance requirements (Section 8). Penalties for non-compliance can include fines, suspension or revocation of airworthiness certificates, and other regulatory measures (Section 9). The severity of the penalties is determined by the nature and extent of the non-compliance, with maximum penalties potentially including substantial financial fines and long-term grounding of the affected aircraft (Section 10).
