Overview
The Civil Aviation Regulations 1998, specifically within Part 39, contains the Civil Aviation Safety Authority's Airworthiness Directives which are issued to address safety issues and ensure compliance with civil aviation safety standards. One such directive, AD/IAI-W/25, was enacted to address a safety concern related to the pressurisation system emergency operating procedures for the Israel Aircraft Industries 1123 and 1124 (Westwind) Series Aeroplanes. This Airworthiness Directive was introduced to mandate specific revisions to the Aircraft Flight Manual (AFM) to mitigate the risk of unsafe cabin conditions, particularly when an excessive cabin altitude warning is activated. The directive, issued by a delegate of the Civil Aviation Safety Authority, aims to ensure that these critical procedures are correctly and promptly implemented to safeguard flight safety. This legislative instrument was notified in the Commonwealth of Australia Gazette on 28 August 2002, and became effective on that date, underscoring the urgency and importance of the safety measures it outlines.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105 Airworthiness Directives, govern the safety standards for civil aviation operations in Australia. This legislative instrument applies to all relevant aircraft operators, manufacturers, and other entities involved in the maintenance and operation of civil aircraft within the Australian jurisdiction. The Airworthiness Directive issued under this regulation applies to Model 1124 and 1124A aeroplanes manufactured by Israel Aircraft Industries, specifically those identified as Series 1123 and 1124. The directive mandates that operators of these aircraft models incorporate temporary revisions to their Aircraft Flight Manuals to address emergency operating procedures in the event of a warning of excessive cabin altitude. These revisions must be implemented before the compliance deadline of 20 September 2002, with the directive itself becoming effective on 28 August 2002. This Airworthiness Directive is issued by the delegate of the Civil Aviation Safety Authority, as authorised under the Civil Aviation Regulations, and is published in the Commonwealth of Australia Gazette to ensure widespread dissemination and compliance.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39 - 105, detail the requirements for the Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA). This directive, AD/IAI-W/25, pertains to the pressurisation system emergency operating procedures for the Israel Aircraft Industries 1124 and 1124A (Westwind) series aeroplanes (sections 1 to 6). The directive mandates that specific temporary revisions (T/R) be incorporated into the Aircraft Flight Manual (AFM) of these aeroplanes. Specifically, T/R No. 3 dated 16 January 2001 is to be inserted into the AFM for the 1124 model, and T/R No. 5 dated 16 January 2001 for the 1124A model (section 7).
The obligations under this AD are clear and direct. Owners and operators of the affected aircraft must ensure that the specified revisions to the AFM are completed before the compliance date of 20 September 2002. This involves updating the emergency operating procedures for the pressurisation system to address situations where a warning of excessive cabin altitude is activated (section 8). The directive references an Israeli CAA AD 21-02-07-01, indicating that the revisions are aligned with international safety standards and practices.
Failure to comply with the AD by the stipulated deadline may result in severe consequences. The AD specifies that it becomes effective on 28 August 2002, and non-compliance can lead to the aeroplanes being deemed non-airworthy. This could result in grounding of the aircraft, which would prevent operation until the necessary changes are made. The AD was issued by James Coyne, a delegate of the CASA, on 19 August 2002, and was officially notified in the Commonwealth of Australia Gazette on 28 August 2002 (sections 9 to 11). While the specific penalties for non-compliance are not detailed in the text, they could include fines, legal action, or other regulatory sanctions as prescribed under the Civil Aviation Act 1988.
