AD/CESSNA 180/36 - Brake Line Adaptor

Overview

The Civil Aviation Regulations 1998, which were enacted by the Parliament of the Commonwealth of Australia, provide a comprehensive framework for ensuring the safety and efficiency of civil aviation within Australia. One of the legislative instruments under this act is F2006B05048, introduced to address specific safety concerns related to certain Cessna aeroplanes. This legislative instrument targets issues identified in the Cessna 180, 182, and Wren 460 series aeroplanes, particularly focusing on the integrity of brake line adaptors. The policy objective behind this regulation is to mitigate the risk of in-flight incidents by ensuring compliance with manufacturer directives regarding the replacement or repair of critical components, thereby enhancing the overall safety standards of civil aviation operations. The enactment of F2006B05048 is a direct response to identified safety gaps, specifically for Model 182 aeroplanes within a defined serial number range. The regulation mandates compliance with Cessna Service Letter SE73-16, requiring actions to be taken within 100 hours of time in service after a specified date, 28 September 1973. This ensures that any potential faults in the brake line adaptors are addressed promptly, reducing the likelihood of safety-critical failures during flight operations.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, specify the application of the Civil Aviation Safety Authority’s airworthiness directives for certain aircraft models. Specifically, Airworthiness Directive AD/CESSNA 180/36 pertains to the Cessna 180, 182, and Wren 460 series aeroplanes, focusing on model 182 with serial numbers ranging from 18261540 to 18262021. This directive mandates compliance with Cessna Service Letter SE73-16, which requires action concerning the brake line adaptor. The directive applies to the specified model and serial number range of aircraft and mandates that the required action be taken within 100 hours of time in service after 28 September 1973. The scope of the legislation is clearly defined in terms of the aircraft models, serial numbers, and the specific maintenance action needed, ensuring safety standards are met within the Commonwealth of Australia.

Key Provisions

The primary sections of the Civil Aviation Regulations 1998 relevant to the Cessna 180, 182 and Wren 460 Series Aeroplanes are those contained within Part 39, specifically AD/CESSNA 180/36, which pertains to the brake line adaptor. This directive, applicable to Model 182 with serial numbers ranging from 18261540 to 18262021, mandates compliance with Cessna Service Letter No. SE73-16. The requirement is to implement the specified action within 100 hours of time in service following 28 September 1973. This directive is crucial for ensuring the airworthiness of the affected aircraft models. The Civil Aviation Safety Authority (CASA) imposes several obligations on the operators of these aircraft models. Primarily, operators must ensure that the specified action regarding the brake line adaptor is completed within the stipulated timeframe. Failure to adhere to the directive can result in the aircraft not being considered airworthy, thereby prohibiting its operation until the required modifications are made. Operators must also keep accurate records of compliance with this directive to demonstrate adherence to CASA's safety standards. Failure to comply with AD/CESSNA 180/36 can result in significant consequences. Operating an aircraft that does not meet the requirements of this directive is a breach of the Civil Aviation Regulations 1998. Such breaches can lead to enforcement actions by CASA, which may include fines, suspension of the aircraft's certificate of airworthiness, or even prosecution. The maximum penalties for non-compliance can vary, but they are designed to ensure that operators take the necessary steps to maintain the safety and airworthiness of their aircraft. Under the Civil Aviation Act 1988, CASA has the authority to impose penalties for non-compliance with airworthiness directives. These penalties can include substantial fines and, in severe cases, criminal charges for operators who fail to comply with mandatory safety directives. The specific penalties are determined based on the severity of the breach and the potential risk posed to public safety. CASA's enforcement actions are aimed at ensuring that all aircraft operate to the highest safety standards, thereby protecting passengers and crew.
