AD/HS 125/144 - Elevator Pulley Assembly

Overview

The Civil Aviation Regulations 1998, specifically Part 39, which deals with airworthiness directives, includes legislation addressing safety concerns in the aviation sector. The regulation F2006B10424 pertains to British Aerospace BAe 125 Series Aeroplanes, targeting the elevator pulley assembly. Enacted by the Australian Government, this directive was introduced to address issues related to the correct assembly of elevator pulleys in certain aircraft models, as incorrectly assembled components had been reported. The policy objective is to ensure the safety of these aircraft by mandating compliance with the Hawker Raytheon Corporate Jets Mandatory Service Bulletin 27-161, which provides specific guidance on correcting the assembly issue. The regulation applies to Model BAe Series 1000A and B, as well as Hawker 1000 aircraft, requiring corrective action to be completed prior to 31 March 1995 to mitigate safety risks.

Scope and Application

The Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, specifically Part 39 - 105, governs the airworthiness of various aircraft, including the British Aerospace BAe 125 Series Aeroplanes, as outlined in the Civil Aviation Regulations 1998. This legislation applies to the BAe Series 1000A and B, as well as the Hawker 1000 aircraft, which are identified in the Requirement Document. The primary objective is to ensure compliance with Hawker Raytheon Corporate Jets Mandatory Service Bulletin 27-161, which mandates action concerning the elevator pulley assembly. This directive is critical for aircraft that were in service prior to 31 March 1995, reflecting CASA's commitment to safety by addressing reported issues with incorrectly assembled elevator pulley installations. The regulation extends its reach nationally across Australia, enforcing strict compliance measures to maintain the safety standards of civil aviation.

Key Provisions

The key operative sections of this legislation (AD/HS 125/144) pertain to the requirements for the elevator pulley assembly on British Aerospace BAe 125 Series Aeroplanes, specifically models BAe Series 1000A and B, and Hawker 1000 aircraft. Section 1 specifies the applicability of this directive to the aforementioned aircraft models, ensuring that only those identified in the Requirement Document are subject to the provisions outlined. Section 2 mandates the action required to address the identified issue, which is in accordance with Hawker Raytheon Corporate Jets Mandatory Service Bulletin 27-161. Section 3 outlines the compliance requirement, stipulating that the necessary action must be taken prior to 31 March 1995. The Act imposes several obligations and requirements on the parties it governs. Primarily, the owner or operator of the applicable aircraft must ensure that the elevator pulley assembly is correctly assembled as per the specifications in the Hawker Raytheon Corporate Jets Mandatory Service Bulletin 27-161. This includes reviewing the Requirement Document to confirm the applicability of the directive to their specific aircraft. Furthermore, the Act mandates that any corrective action must be completed and documented before the specified deadline of 31 March 1995. This ensures that all affected aircraft meet the necessary safety standards set forth by the Civil Aviation Safety Authority. In terms of breaches and consequences, the legislation does not explicitly state the offences, penalties, or consequences for non-compliance within the provided excerpt. However, non-compliance with Civil Aviation Regulations 1998, particularly with directives issued by the Civil Aviation Safety Authority, can result in significant legal and safety repercussions. Such breaches could potentially lead to aircraft being grounded, resulting in substantial financial and operational disruptions. Moreover, the authority may impose administrative penalties, including fines, and in severe cases, criminal charges could be pursued against the responsible parties. The exact penalties would depend on the specific circumstances and the discretion of the regulatory body enforcing the regulations.
