AD/CESSNA 400/65 - Exhaust System Coupling - Replacement

Overview

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, address the critical area of aircraft airworthiness directives to ensure the safety of Australian airspace. This legislation was enacted to maintain a robust framework for the regulation of civil aviation, particularly focusing on ensuring that aircraft meet specific safety standards. The Civil Aviation Safety Authority (CASA) is the enacting body responsible for overseeing the compliance with these regulations. The overarching policy objective is to safeguard the highest possible level of safety in civil aviation through stringent adherence to airworthiness directives, thus preventing potential hazards and ensuring public confidence in air travel. One particular directive, AD/CESSNA 400/65, targets the exhaust system coupling of Cessna 400 Series aeroplanes, specifically models 404 and 414A within certain serial number ranges. This directive mandates the replacement of the exhaust system coupling within 100 hours of time in service after 31 March 1979, as documented in Cessna SL ME78-38. This regulation was introduced to address specific safety concerns identified with the exhaust system coupling, aiming to mitigate risks associated with potential failures and ensure the continued airworthiness of these aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, pertains to the mandatory compliance of certain aircraft with safety directives. This particular legislation applies to the Cessna 400 series aeroplanes, specifically Models 404 and 414A with specific serial numbers. The directive mandates the replacement of the exhaust system coupling on these models, as outlined in the document Cessna SL ME78-38. Compliance is required within 100 hours of time in service after the directive's issuance date of 31 March 1979. The scope of this legislation is focused on ensuring the airworthiness and safety of the specified aircraft models within the Australian jurisdiction, with no stated exclusions or exemptions within the provided text. The legislation extends its application through the issuance of specific directives that must be adhered to by the owners and operators of the affected aircraft.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 (sections 39-105), address the applicability and compliance requirements for the Cessna 400 series aeroplanes, including models 404 and 414A, concerning exhaust system coupling replacement. The regulations mandate that model 404 with serial numbers ranging from 404-0001 to 404-0220 and model 414A with serial numbers from 414A0001 to 414A0040 must comply with the directive within 100 hours of time in service after 31 March 1979. Compliance must be achieved by following the instructions detailed in the document Cessna SL ME78-38. Entities governed by these regulations, particularly those involved in the maintenance and operation of the specified Cessna models, must ensure that the exhaust system coupling is replaced as per the directive within the stipulated timeframe. This requirement is non-negotiable and must be strictly adhered to, ensuring the safety and airworthiness of the aircraft. It is imperative that the relevant parties maintain detailed records of compliance, including the serial numbers of the aircraft and the dates on which the replacement was performed. Failure to comply with these directives can result in serious legal and operational repercussions. Under the Civil Aviation Regulations 1998, non-compliance may lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The consequences can include fines, penalties, or even the grounding of the aircraft until the required maintenance is performed. The maximum penalties for breaches may vary, but they are designed to enforce stringent safety standards within the aviation industry. Therefore, it is crucial for all involved parties to understand and adhere to these regulations to avoid potential legal and safety issues.
