Overview
The Civil Aviation Regulations 1998, enacted by the Australian Government, provide comprehensive regulations for ensuring civil aviation safety. Specifically, Part 39 - 105 of the Regulations pertains to the Civil Aviation Safety Authority's schedule of airworthiness directives, which are crucial for maintaining the safety standards of aircraft. One such directive, AD/LEARJET/19, addresses the potential issue of improperly installed or non-serviceable drain holes in the aileron lower skin of Gates Learjet 24 and 25 series aeroplanes. This directive aims to ensure that the specified models are compliant within 100 hours of time in service after 31 March 1980, thereby mitigating risks associated with faulty installations that could compromise the aircraft's structural integrity and safety. The policy objective is to uphold stringent safety standards and protect the interests of passengers and crew by mandating regular inspections and necessary repairs.
The enactment of this regulation by the Civil Aviation Safety Authority under the authority granted by the Civil Aviation Act 1988, demonstrates a commitment to addressing specific safety concerns in aviation. By issuing airworthiness directives such as AD/LEARJET/19, the Civil Aviation Safety Authority ensures that aircraft maintain operational safety and reliability, thereby protecting the public and supporting the broader objectives of the aviation industry.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, sets out the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, including AD/LEARJET/19, which mandates an inspection of the aileron lower skin for Gates Learjet 24 & 25 Series Aeroplanes. This directive applies to all model 23 aeroplanes with serial numbers from 23-003 to 23-099, all model 24 aeroplanes with serial numbers from 24-100 to 24-357, and all model 25 aeroplanes with serial numbers from 25-003 to 25-291. The directive requires compliance within 100 hours of time in service after 31 March 1980. This applies to the identified aircraft models and serial numbers, focusing on ensuring the drain holes in the aileron lower skin are correctly installed and serviceable, as detailed in Gates Learjet Service Bulletin No. 23/24/25-295. The directive operates under the Commonwealth of Australia and applies to the specified aircraft within its jurisdiction, with no stated exclusions or exemptions in this particular directive.
Key Provisions
The Civil Aviation Regulations 1998, specifically under PART 39 - 105, establish Airworthiness Directives (ADs) that are crucial for maintaining the safety and airworthiness of aircraft. One such AD is AD/LEARJET/19, which pertains to the inspection of the aileron lower skin of Gates Learjet 24 and 25 series aeroplanes (sections 1 and 2). This directive applies to specific serial numbers within the 23, 24, and 25 series of Gates Learjet aircraft, as outlined in the applicability section (section 3). The directive is grounded in Gates Learjet Service Bulletin No. 23/24/25-295, which addresses potential issues with the drain holes in the aileron lower skin (section 4). Compliance with this AD is mandatory, requiring an inspection to be conducted within 100 hours of time in service after 31 March 1980 (section 5).
The obligations imposed by AD/LEARJET/19 are clear and direct. Aircraft operators and owners must ensure that the specified Gates Learjet 24 and 25 series aeroplanes undergo an inspection of the aileron lower skin to verify the correct installation and serviceability of the drain holes (section 6). This inspection is critical to maintaining the aircraft's airworthiness and must be completed within the stipulated timeframe to avoid any potential safety risks (section 7). Failure to comply with this requirement may lead to significant consequences, including the grounding of the aircraft until the inspection is performed.
In terms of the consequences for non-compliance, the Civil Aviation Regulations 1998 outline serious penalties and potential legal ramifications. Operators who fail to adhere to the inspection requirements of AD/LEARJET/19 may face significant financial penalties, as stipulated by the regulations (section 8). Moreover, continued operation of a non-compliant aircraft could result in severe civil or criminal liability, including the potential for prosecution under aviation safety laws (section 9). The specific maximum penalties for such breaches are determined by the regulatory authority and may include fines or imprisonment, depending on the severity and circumstances of the non-compliance (section 10).
