AD/HS 125/152 - Hydraulic Pipes

Overview

The Civil Aviation Regulations 1998, under the authority of the Australian Government, establish stringent safety standards to govern civil aviation operations within Australia. One such regulation pertains to the maintenance and airworthiness of aircraft, specifically addressing the British Aerospace BAe 125 Series Aeroplanes. This regulation, part of the broader safety framework, aims to mitigate potential risks associated with identified issues in aircraft design and operation. The Civil Aviation Safety Authority (CASA) issues specific directives, such as AD/HS 125/152, to ensure compliance with these safety standards. These directives mandate that all BAe 125 series 1000A, 1000B, and Hawker 1000 aircraft must adhere to the requirements set out in Hawker Raytheon Corporate Jets Mandatory Service Bulletin SB.29-95, which has been classified as mandatory by the UK Civil Aviation Authority. The directive addresses the reported issue of chafing between the equipment bay structure and hydraulic lines, necessitating action to be taken by 31 June 1995 to ensure continued safe operation of these aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all BAe 125 series 1000A, 1000B and Hawker 1000 aircraft within the Commonwealth of Australia. The legislation mandates compliance with Hawker Raytheon Corporate Jets Mandatory Service Bulletin SB.29-95 to address reported instances of chafing between the equipment bay structure and hydraulic lines. The regulation requires that any necessary action be completed by 31 June 1995, as the UK Civil Aviation Authority has classified this bulletin as mandatory. This directive is part of the broader schedule of airworthiness directives managed by the Civil Aviation Safety Authority, ensuring that aircraft within the specified series meet essential safety standards. The regulations apply nationally and are enforced by the Commonwealth, with no stated exclusions or exemptions in this specific directive.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Subpart 105, includes an Airworthiness Directive (AD) pertaining to British Aerospace BAe 125 Series Aeroplanes (sections 39-105). This directive, identified as AD/HS 125/152, mandates actions regarding hydraulic pipes on all BAe 125 series 1000A, 1000B, and Hawker 1000 aircraft. The directive requires adherence to Hawker Raytheon Corporate Jets' Mandatory Service Bulletin SB.29-95, which has been classified as mandatory by the UK Civil Aviation Authority. The compliance deadline is set for 31 June 1995, reflecting the urgency to address reported chafing between the equipment bay structure and hydraulic lines. This legislation imposes clear obligations on the operators of BAe 125 series 1000A, 1000B, and Hawker 1000 aircraft. Primarily, these obligations include ensuring that all required actions outlined in Hawker Raytheon Corporate Jets' Mandatory Service Bulletin SB.29-95 are performed without delay. This involves detailed inspections and necessary repairs or replacements of hydraulic pipes to prevent any potential chafing issues. Operators must document all actions taken to comply with the directive, ensuring that the aircraft remain airworthy and meet the safety standards set by the Civil Aviation Safety Authority. Failure to comply with the provisions of AD/HS 125/152 may result in significant legal consequences. Under the Civil Aviation Act 1988, non-compliance could lead to civil penalties, which may include substantial fines. Additionally, continued operation of an aircraft that does not meet the requirements of this directive could result in criminal charges, leading to imprisonment for the operator or relevant individuals responsible for the oversight of the aircraft. The severity of these penalties underscores the importance of adhering to the mandated safety directives to ensure the safety of all passengers and crew on board. In summary, the Civil Aviation Regulations 1998, through AD/HS 125/152, establish stringent requirements for the maintenance and inspection of hydraulic pipes on specific BAe 125 series aircraft. Operators must strictly follow the mandatory service bulletin SB.29-95 to prevent any issues arising from chafing between the equipment bay structure and hydraulic lines. Non-compliance not only risks the airworthiness of the aircraft but also carries significant civil and criminal penalties, including fines and imprisonment. This directive is crucial for maintaining the highest safety standards in civil aviation.
