AD/IAI-W/2 - Aileron Control Pulley P/N 3533032-1 - Inspection

Overview

The Civil Aviation Regulations 1998, as amended by the Legislative instrument F2006B10795, address the safety concerns associated with the aileron control pulleys in the Israel Aircraft Industries 1123 and 1124 (Westwind) Series Aeroplanes. This legislation was enacted by the Australian Government to ensure that the airworthiness directives are effectively implemented and maintained, thereby enhancing the safety standards of civil aviation. The specific problem it addresses involves the potential for abnormal wear of the aileron control pulleys, which could compromise the aircraft's safety. The policy objective of this regulation is to mandate regular inspections of the aileron control pulleys on model 1124 aircraft with serial numbers between 240 and 275 to mitigate the risk of chafing by cables. Compliance with these directives is required within 150 hours of time in service after 30 November 1980, as outlined in IAI Service Bulletin No. 1124-27-02.

Scope and Application

The Civil Aviation Regulations 1998, as amended, govern the operation of civil aviation in Australia and include specific directives to ensure the safety and airworthiness of aircraft. Part 39, which deals with airworthiness directives, applies to all aircraft registered in Australia and those operated by Australian carriers, regardless of location. Specifically, the AD/IAI-W/2 directive targets all model 1124 Westwind aircraft with serial numbers ranging from 240 to 275. This directive mandates an inspection of the aileron control pulley P/N 3533032-1, as specified in IAI SB No. 1124-27-02, to be conducted within 150 hours of time in service following 30 November 1980. The purpose of this directive is to address potential chafing of control pulleys by cables, which could otherwise lead to abnormal wear and compromise the aircraft's safety. The scope of this regulation extends to ensuring compliance with the Civil Aviation Safety Authority's standards and involves inspections that may be further detailed through subordinate instruments or guidance documents.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Section 105, include an Airworthiness Directive (AD) concerning Israel Aircraft Industries (IAI) 1123 and 1124 (Westwind) series aeroplanes. This AD, numbered AD/IAI-W/2, pertains to the inspection of the aileron control pulley, part number 3533032-1, for the affected model 1124 aeroplanes with serial numbers ranging from 240 to 275. The directive was issued on 11 August 1980 and references IAI Service Bulletin No. 1124-27-02. The key requirement outlined in this AD is that the specified aileron control pulleys must be inspected within 150 hours of time in service after 30 November 1980. The reasoning behind this inspection mandate is to identify any chafing on the control pulleys caused by the cables, which could otherwise lead to abnormal wear. Such wear may compromise the structural integrity and operational safety of the aeroplanes. Compliance with this directive is essential for maintaining the airworthiness of the affected aircraft. Operators and owners of IAI 1124 aeroplanes within the specified serial number range must ensure that the aileron control pulleys are inspected as per the directive's timeline and guidelines. Failure to comply with this requirement may result in the aeroplane being deemed unairworthy, thereby preventing its operation until the necessary inspections and repairs are completed. The Civil Aviation Regulations impose strict obligations on operators and owners to adhere to the terms of the AD. Non-compliance can lead to significant consequences, including potential enforcement actions by the Civil Aviation Safety Authority (CASA). The seriousness of these consequences underscores the importance of timely and thorough compliance with airworthiness directives. In cases of non-compliance, the authorities may take civil or criminal action, which could include fines or other penalties as stipulated by the regulations. In terms of penalties, the specific consequences for breaching the AD are not detailed in the provided text. However, under the broader framework of the Civil Aviation Regulations, violations of airworthiness directives can result in severe penalties. Civil penalties may include fines and enforcement orders, while more serious breaches could lead to criminal charges. The exact penalties would depend on the nature and severity of the breach, as well as the specific provisions of the Civil Aviation Act 1988 and associated regulations.
