Overview
The Civil Aviation Regulations 1998 (Cth), as amended by the Legislative Instrument F2006B08314, specifically address the safety and operational standards for civil aviation in Australia. This particular instrument was enacted to fill a gap in ensuring that aircraft maintenance and operational procedures adhere to stringent safety standards. The instrument was developed and enacted by the Australian Government under the authority of the Civil Aviation Act 1988 (Cth), with the primary objective of maintaining and enhancing the safety of civil aviation within Australia. The policy objective behind this legislation is to ensure that all civil aircraft, including the Cessna 400 Series Aeroplanes, meet the required safety standards to protect the public and enhance the overall safety of the aviation industry. This is achieved through the incorporation of specific directives, such as the requirement for a warning arc and placard on the engine tachometer for certain models of Cessna aircraft.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses airworthiness directives issued by the Civil Aviation Safety Authority (CASA) concerning Cessna 400 Series Aeroplanes. The particular directive AD/CESSNA 400/29 pertains to the incorporation of a warning arc and placard on the engine tachometer for Model 411 and 421 series aircraft with serial numbers prior to 421B0148. This directive applies to these specific aircraft models to ensure compliance with safety standards, requiring the modification to be implemented within 50 hours of time in service after the directive's issuance date of 6 March 1972, as referenced in the Cessna SL ME71-16 Supplement No. 2. The regulation's scope is confined to the specified aircraft models and serial numbers, ensuring that the modifications are strictly adhered to for safety compliance.
Key Provisions
The Civil Aviation Regulations 1998, specifically under Part 39 - 105, provide detailed guidance on airworthiness directives for aircraft in the Australian aviation sector. In the case of Cessna 400 Series Aeroplanes, the regulation AD/CESSNA 400/29 outlines the incorporation of a warning arc and placard for the engine tachometer. This directive applies to Model 411 and 421 series with serial numbers prior to 421B0148 (Section 39.105). The directive mandates that these aircraft must incorporate the specified modifications to ensure continued airworthiness and safety. Compliance with these provisions is mandatory and must be achieved within 50 hours of time in service following the issuance date of 6 March 1972, as detailed in the document Cessna SL ME71-16 Supplement No. 2.
The obligations imposed by this directive are clear and precise. Aircraft operators and owners of the specified Cessna 400 Series models must ensure that their aircraft meet the requirements of AD/CESSNA 400/29. This includes the installation of the warning arc and placard on the engine tachometer as outlined in the directive. Failure to comply with these requirements within the specified timeframe could result in the aircraft being deemed non-airworthy, which would prohibit it from flying until the necessary modifications are made. Additionally, operators must ensure that all modifications are properly documented and that the aircraft is inspected to verify compliance with the directive.
Failure to comply with the airworthiness directive AD/CESSNA 400/29 can lead to serious consequences. Non-compliance may result in the aircraft being grounded, which could have significant operational and financial implications for the operator. Furthermore, there may be regulatory penalties for failing to adhere to the specified compliance timeframe. While the Civil Aviation Regulations do not explicitly state the maximum penalties for non-compliance in this context, violations of aviation regulations generally can result in fines and other sanctions. It is essential for operators to adhere to the directive to avoid any legal repercussions and to maintain the safety standards required by the Civil Aviation Safety Authority.
