AD/CESSNA 310/46 - Engine Mount - Inspection and Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, provide a comprehensive regulatory framework for civil aviation in Australia. The legislation, overseen by the Civil Aviation Safety Authority (CASA), ensures the safety and efficiency of the nation's aviation industry. One aspect of this regulatory approach is evident in Part 39, specifically Airworthiness Directives, which mandate safety improvements for certain aircraft. For example, Airworthiness Directive AD/CESSNA 310/46 pertains to the inspection and replacement of engine mounts on Cessna 310R series aeroplanes with serial numbers ranging from 310R0501 to 310R0692. This directive aims to rectify identified safety issues, ensuring that these aircraft meet the required safety standards. The policy objective of such directives is to mitigate potential risks and enhance the overall safety of civil aviation operations within Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to all model 310R Cessna 310 Series Aeroplanes with serial numbers ranging from 310R0501 to 310R0692. This legislation mandates an inspection and replacement of the engine mount within the next 25 hours of time in service following 30 March 1977, as outlined in document Cessna SL ME77-4. The directive ensures compliance with safety standards set forth by the Civil Aviation Safety Authority, thereby regulating the airworthiness of the specified aircraft within the Commonwealth of Australia. This regulation is applicable nationally, impacting operators and owners of the affected Cessna 310R series aeroplanes. There are no stated exclusions or exemptions within the provided text, and the application extends to all relevant aircraft without additional geographic or jurisdictional limitations. The enforcement of these directives may be further detailed or extended through subordinate instruments, ensuring comprehensive adherence to safety protocols.

Key Provisions

The key provisions of the Civil Aviation Regulations 1998, specifically within Part 39 - 105, mandate certain actions for Cessna 310 Series aeroplanes, particularly model 310R with serial numbers ranging from 310R0501 to 310R0692. Section 39.105(46) outlines the necessity for an inspection and potential replacement of the engine mount. This directive is applicable to aircraft that have accumulated 25 hours of time in service following the date of 30 March 1977. The directive is detailed in document Cessna SL ME77-4, which provides the technical and procedural guidelines for compliance. The obligations imposed by this regulation are clear and specific. Aircraft owners or operators must ensure that the inspection and any required replacement of the engine mount are carried out within the stipulated 25 hours of time in service after 30 March 1977. This involves meticulous record-keeping and adherence to the technical specifications and procedures outlined in the referenced document. Failure to comply with these requirements can lead to serious consequences for the safety and airworthiness of the aircraft. Non-compliance with the provisions of AD/CESSNA 310/46 can result in significant legal and operational repercussions. Section 39.105(46) stipulates that any breach of these directives can be considered an offence. The potential penalties for such breaches include fines and potential criminal charges, which can be severe depending on the extent of the non-compliance and its impact on aviation safety. The specific maximum penalties are not detailed in the provided text, but it is clear that adherence to the Airworthiness Directive is crucial to avoid these legal and safety-related consequences.
