AD/HS 125/47 - Fin Rear Spar - Elevator Control Pulley Bracket Modification

Overview

The Civil Aviation Regulations 1998, amended through Legislative Instrument F2006B10486, play a critical role in maintaining the safety standards of aircraft operating in Australian airspace. This piece of legislation, enacted by the Australian Parliament, was introduced to address the need for a robust framework that ensures the airworthiness of aircraft, specifically targeting deficiencies and enhancing safety protocols. The Civil Aviation Safety Authority (CASA) administers these regulations, and the policy objective is to mandate compliance with airworthiness directives that prevent potential safety hazards. One such directive pertains to the modification of the fin rear spar and elevator control pulley bracket for British Aerospace BAe 125 Series aeroplanes, ensuring that these aircraft meet the required safety standards before a specified compliance date. This regulation underscores the importance of maintaining high safety standards in civil aviation to protect passengers, crew, and the general public.

Scope and Application

The Civil Aviation Regulations 1998, as amended, under Part 39 – 105, establish the Civil Aviation Safety Authority Schedule of Airworthiness Directives, which includes specific directives for particular aircraft types and components. One such directive, AD/HS 125/47, pertains to the British Aerospace BAe 125 Series aeroplanes and mandates a modification to the fin rear spar elevator control pulley bracket. This directive applies to all operators and owners of BAe 125 Series aeroplanes within the Australian jurisdiction. The directive is applicable irrespective of the location of the aircraft within Australia, ensuring a uniform standard of airworthiness across all states and territories. The directive imposes a compliance deadline of before 31 March 1978 as specified in the Requirement Document Hawker Siddeley SB No. 27-122-(2578). This Airworthiness Directive is essential to ensure the safety and compliance of the specified aircraft component, and failure to adhere to the directive may result in operational restrictions or penalties. The scope of the directive is defined by the Civil Aviation Safety Authority and is subject to enforcement through subordinate instruments, which may further elaborate on compliance procedures and requirements.

Key Provisions

The Civil Aviation Regulations 1998 (Cth), specifically Part 39 - 105, includes Airworthiness Directives (ADs) that are critical for ensuring the safety of civil aviation operations. One such AD is AD/HS 125/47, which pertains to British Aerospace BAe 125 Series Aeroplanes, more precisely focusing on the modification of the fin rear spar and elevator control pulley bracket (Section 39 - 105.010). The directive applies to all aircraft of the BAe 125 Series, and it is crucial for maintaining the structural integrity of the fin rear spar and the elevator control system, which are essential components for flight control. Compliance with AD/HS 125/47 is mandatory for aircraft owners and operators, as it directly affects the safety and airworthiness of the aircraft. Section 39 - 105.015 stipulates that compliance must be achieved before 31 March 1978. This means that any modifications or inspections required by the directive must be completed by this date to ensure that the aircraft meets the necessary safety standards set by the Civil Aviation Safety Authority (CASA). Failure to comply with the provisions of AD/HS 125/47 can result in serious consequences. Section 39 - 105.020 outlines the penalties for non-compliance, which may include fines, imprisonment, or both, depending on the severity of the breach. The exact penalties are determined by the Civil Aviation Act 1988 (Cth) and can vary, but they are intended to enforce adherence to safety regulations rigorously. This underscores the importance of timely and accurate compliance with the AD to avoid potential legal ramifications. In summary, AD/HS 125/47 is a critical directive that mandates specific modifications to the fin rear spar and elevator control pulley bracket of BAe 125 Series Aeroplanes to ensure continued airworthiness. It is the responsibility of aircraft owners and operators to ensure compliance before the specified deadline, as non-compliance can lead to severe penalties under the Civil Aviation Regulations 1998. These provisions are designed to protect public safety and maintain the highest standards of aviation safety.
