Overview
The Civil Aviation Regulations 1998, amended by the Legislative instrument F2006B10786, were enacted to ensure the safety and airworthiness of civil aircraft within Australia. This regulation specifically addresses a gap identified in the maintenance and operational safety of certain Israel Aircraft Industries (IAI) Westwind Series Aeroplanes. The Civil Aviation Safety Authority (CASA) introduced this directive to mitigate risks associated with elevator and rudder control interference that could arise from existing hardware installations. The policy objective is to ensure compliance with service bulletins and maintain the safety standards of aircraft operations. The regulation mandates that affected aircraft models must adhere to the specific action outlined in the 1124 Westwind Service Bulletin No 1124-22-072 within 100 hours of time in service after 31 May 1986, thereby enhancing the safety profile of these aircraft models.
Scope and Application
The Civil Aviation Safety Authority (CASA) regulations, specifically Part 39 - 105 within the Civil Aviation Regulations 1998, govern the airworthiness directives for Israel Aircraft Industries 1123 and 1124 (Westwind) Series Aeroplanes, which are detailed in AD/IAI-W/11. These regulations apply to specific models and serial numbers of the Westwind aircraft, excluding those identified as 418, 423, 426, 429, 431, 432, and 435. The directive mandates action to address potential elevator and rudder control interference with existing hardware, as stipulated in the 1124 Westwind Service Bulletin No 1124-22-072, to be undertaken within 100 hours of the aircraft's time in service after 31 May 1986. The regulations are applicable nationally, extending to all operators within the Commonwealth of Australia and ensuring compliance with the specified requirements to maintain the safety standards of the aircraft. This directive does not explicitly mention any exclusions or exemptions but implies that non-compliance could lead to safety issues, thereby necessitating adherence to the mandated actions.
Key Provisions
The Civil Aviation Regulations 1998, specifically under PART 39 - 105, contains an Airworthiness Directive (AD) concerning the Israel Aircraft Industries 1123 and 1124 (Westwind) series aeroplanes, detailed in AD/IAI-W/11. This AD applies to model 1124 and 1124A Westwinds with all serial numbers prior to 437, with exceptions for the serial numbers 418, 423, 426, 429, 431, 432, and 435. The directive requires action to be taken in accordance with the 1124 Westwind Service Bulletin No 1124-22-072, which addresses the possibility of elevator and/or rudder control interference with existing hardware. Compliance with this directive is mandatory within 100 hours of time in service after 31 May 1986.
The obligations imposed by this AD are primarily focused on ensuring the airworthiness of the specified aircraft. Owners and operators of the affected aircraft must adhere to the service bulletin’s instructions, which likely involve modifications or checks to the elevator and rudder servo installations. The Civil Aviation Safety Authority (CASA) mandates these actions to mitigate the risk of control interference, which could potentially lead to hazardous flight conditions. Compliance must be verified, and records must be maintained to demonstrate adherence to the AD.
Breaching the requirements of this AD can result in significant consequences. Civil penalties can be imposed for non-compliance, including fines and other enforcement actions by CASA. In more severe cases, continued operation of the aircraft without addressing the identified issues may lead to grounding of the aircraft until the required actions are completed. Additionally, there could be criminal implications for operators who knowingly permit unsafe operations, potentially leading to prosecution and substantial penalties. The exact penalties are not specified in the provided text, but they can include fines and imprisonment, depending on the severity and circumstances of the breach.
