Overview

The Civil Aviation Regulations 1998, as amended by the legislative instrument F2006B08349, were enacted to provide comprehensive safety standards and regulations for civil aviation in Australia. This legislation is essential in ensuring that all civil aviation operations within the country adhere to stringent safety protocols. The specific Airworthiness Directive AD/CESSNA 400/64, issued under this regulatory framework, targets the inspection of hydraulic lines in Model 404 Cessna 400 Series Aeroplanes with serial numbers 404-0001 to 404-0404. The directive aims to address potential safety issues by requiring inspections within 100 hours of time in service after 28 February 1979, as documented in Cessna Service Letter No. ME78-42. The objective of this directive is to maintain the airworthiness of these aircraft by mitigating risks associated with hydraulic line integrity, thereby enhancing overall flight safety. The Civil Aviation Regulations 1998 were enacted by the Parliament of Australia to provide a robust legislative foundation for civil aviation safety. The policy objective behind these regulations is to ensure the highest standards of safety and efficiency in Australia's civil aviation sector. The specific Airworthiness Directive AD/CESSNA 400/64 under this regulatory framework highlights the commitment to addressing identified safety concerns proactively. By mandating regular inspections of hydraulic lines in specified Cessna 400 Series aircraft, the directive aims to prevent potential failures that could compromise flight safety. This targeted approach underscores the regulatory body's dedication to continuous improvement and risk management in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, which pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, addresses the mandatory compliance requirements for specific aircraft models. This particular legislation targets the Cessna 400 series aeroplanes, more specifically model 404 with serial numbers ranging from 404-0001 to 404-0404. This directive, AD/CESSNA 400/64, mandates that inspections of hydraulic lines must be carried out within 100 hours of time in service following 28 February 1979. The regulation applies to aircraft that fall under the specified serial number range and adheres to the document Cessna SL No. ME78-42. This directive is enforced under the Commonwealth of Australia, ensuring that all applicable aircraft meet the required safety standards. The scope of this regulation is limited to the specified model and serial numbers, and it does not extend to other aircraft models or serial numbers outside this range. The regulation’s enforcement ensures compliance within the designated operational parameters, thereby maintaining airworthiness and safety standards for the specified Cessna 400 series aeroplanes.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105, provide specific directives for ensuring the airworthiness of aircraft. In this case, AD/CESSNA 400/64 pertains to Cessna 400 series aeroplanes, specifically model 404 with serial numbers ranging from 404-0001 to 404-0404. The directive mandates a detailed inspection of the hydraulic lines on these aircraft. This requirement is outlined in the Cessna Service Letter No. ME78-42 and must be carried out within 100 hours of the aircraft being in service after 28 February 1979. Compliance with AD/CESSNA 400/64 is mandatory for the specified models and serial numbers of Cessna 400 series aeroplanes. The directive imposes a clear obligation on aircraft operators to conduct the inspection as per the specified timeframe. This involves a thorough examination of the hydraulic lines to ensure they are free from any defects, wear, or damage that could compromise the aircraft's safety. The operators must document the inspection and ensure that all identified issues are rectified before the aircraft returns to service. Failure to comply with AD/CESSNA 400/64 could lead to significant consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce penalties for non-compliance. The severity of the penalties may depend on the nature and extent of the breach, but they can include fines, suspension of the aircraft's certificate of airworthiness, or even prosecution under civil or criminal law. The maximum penalties for non-compliance with airworthiness directives are substantial, reflecting the critical importance of adhering to safety standards in aviation. It is essential for aircraft operators to take these directives seriously and ensure strict adherence to the specified requirements to avoid legal repercussions.
