Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, includes the Civil Aviation Safety Authority Schedule of Airworthiness Directives, which was enacted to ensure the safety and airworthiness of aircraft operating within Australian airspace. One such directive, AD/HS 125/119 Amendment 1, pertains to the British Aerospace BAe 125 Series Aeroplanes, particularly Series 800A and 800B, and mandates a modification to the Main Landing Gear (MLG) torque links to improve resistance to vibration. This was introduced to address potential safety issues that could arise from inadequate torque link durability. The policy objective of these regulations is to maintain and enhance the safety standards of civil aviation, ensuring that all aircraft meet stringent airworthiness criteria. This directive was issued by the Civil Aviation Safety Authority and became effective on 23 April 1998, following its original issue on 8 August 1991, to ensure compliance with the requirements set out by the British Aerospace Service Bulletin and the UK Civil Aviation Authority Airworthiness Directive.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all operators and owners of British Aerospace BAe 125 Series aeroplanes within the Commonwealth of Australia, enforcing compliance with the Airworthiness Directives issued by the Civil Aviation Safety Authority. This Act mandates that operators and owners of BAe 125 Series 800A and 800B aeroplanes must adhere to the specified modifications concerning the MLG (Main Landing Gear) torque links as outlined in the Mandatory BAe Service Bulletin 32-226-3257A. This requirement aims to enhance the torque link's resistance to vibration, ensuring the continued airworthiness and safety of these aircraft. The geographic scope of the Act is national, applying across all states and territories within Australia. The directive's compliance must align with the specified requirement document, with the original directive's compliance terms remaining unchanged by this amendment, which became effective on 23 April 1998. The application of this directive is further referenced to the UK Civil Aviation Authority's Airworthiness Directive 002-05-91.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Civil Aviation Safety Authority’s (CASA) schedule of airworthiness directives. Within this part, AD/HS 125/119 Amendment 1 pertains to British Aerospace BAe 125 Series aeroplanes, specifically models 800A and 800B. This directive mandates an action in accordance with the Mandatory BAe Service Bulletin (SB) 32-226-3257A. The directive references UK Civil Aviation Authority (CAA) AD 002-05-91 for additional context, ensuring that the compliance standards set forth are clear and consistent with international safety practices. The directive became effective on 8 August 1991, and its compliance requirements remain unchanged; however, Amendment 1 was issued to reinstate this directive for the specified series, effective from 23 April 1998. The directive imposes specific obligations on aircraft operators and maintenance personnel regarding the modification of MLG (Main Landing Gear) torque links. Operators must ensure that the modifications are carried out in strict adherence to the guidelines provided in the Mandatory BAe SB 32-226-3257A. This includes following detailed technical instructions to enhance the resistance of torque links to vibration, a critical safety measure. Compliance is non-negotiable and must be achieved as specified in the requirement document, ensuring that the structural integrity of the landing gear is maintained and any potential risks are mitigated. Failure to comply with the provisions outlined in AD/HS 125/119 Amendment 1 could lead to serious safety concerns. The regulations do not explicitly state penalties within this specific directive; however, non-compliance with CASA directives generally can result in significant civil and criminal consequences. Operators found in breach of airworthiness directives may face enforcement actions by CASA, including fines, operational restrictions, and potential criminal charges. The seriousness of these consequences underscores the importance of adhering to the directive to maintain the safety and airworthiness of the aircraft in question.
