AD/HS 125/128 Amdt 1 - Rear Equipment Bay Drain Masts

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, establish a comprehensive framework for the safety and regulation of civil aviation within Australia. Among these regulations, Part 39 specifically addresses airworthiness directives, ensuring that aircraft maintain the highest safety standards. The legislative instrument F2006B10407, concerning the British Aerospace BAe 125 Series Aeroplanes, was introduced to address a specific safety concern regarding the rear equipment bay drain masts. The objective of this instrument is to ensure compliance with mandatory safety bulletins, preventing the reingestion of fluids which could compromise the aircraft's safety. This directive was issued by the Civil Aviation Safety Authority to ensure that modifications are made in accordance with the latest requirements, thus maintaining the airworthiness of the affected aircraft models. This legislative instrument underscores the commitment of the Australian government, through the enactment of the Civil Aviation Regulations 1998 by the Commonwealth Parliament, to continuously update and enforce safety standards in civil aviation. By issuing amendments such as AD/HS 125/128 Amendment 1, the Civil Aviation Safety Authority aims to mitigate potential safety hazards and ensure that all aircraft operate within the stringent safety parameters set forth by Australian aviation law.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives for the British Aerospace BAe 125 Series Aeroplanes, targeting the rear equipment bay drain masts. This legislation applies to the specified models of the BAe 125 Series as detailed in BAe 125 Service Bulletin 53-74-3193, Change and Development Revision 1. The regulation mandates compliance with the requirements outlined in the aforementioned Service Bulletin, ensuring that the action required is completed in line with the directive. The directive demands that compliance must be achieved unless the requirements have already been met under the initial issue of this directive, and it must be completed prior to 31 October 1992. The amendment to this directive, effective from 20 August 1992, responds to a revision in the requirement document, expanding the scope and including the removal of additional access panels in the accomplishment instructions to prevent fluid reingestion by ensuring proper fluid venting clear of the rear fuselage structure. This regulation applies nationally, overseen by the Commonwealth of Australia, and is subject to enforcement by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105, includes specific directives that pertain to the maintenance and safety standards of civil aircraft, such as the British Aerospace BAe 125 Series aeroplanes. Section 39.105 of the Civil Aviation Regulations mandates compliance with airworthiness directives issued by the Civil Aviation Safety Authority (CASA). One such directive, AD/HS 125/128 Amendment 1, addresses the rear equipment bay drain masts of the BAe 125 Series aircraft. Under this directive, it is required that modifications be made to the rear equipment bay drain masts to ensure that fluid venting is clear of the rear fuselage structure, thus preventing any possibility of reingestion. This requirement is aligned with the British Aerospace Mandatory Service Bulletin (SB) 53-74-3193 C&D Revision 1. The directive specifies that this action must be completed unless the aircraft has already undergone the necessary modifications as per the initial directive. Importantly, compliance with this amendment must be achieved before 31 October 1992, with the amendment itself becoming effective from 20 August 1992. The obligations imposed by this directive are quite specific and technical. Operators of BAe 125 Series aircraft must ensure that the modifications are carried out in accordance with the detailed instructions provided in the referenced Service Bulletin. This includes the removal of additional access panels as outlined in the revision to the Requirement Document. Failure to adhere to these specifications can result in non-compliance with the Civil Aviation Regulations, potentially leading to safety issues and regulatory penalties. Breaches of the Civil Aviation Regulations, including failure to comply with airworthiness directives such as AD/HS 125/128 Amendment 1, can result in significant consequences. The Civil Aviation Act 1988 provides for both civil and criminal penalties for non-compliance. Civil penalties can include substantial fines, with the exact amount determined by the severity of the breach and the specific regulatory provisions violated. In more severe cases, criminal charges may be brought against individuals or corporations responsible for the non-compliance, potentially leading to imprisonment. The exact penalties are set out in the Civil Aviation Regulations and can vary depending on the circumstances of the breach.
