AD/M20/30 Amdt 2 - Control Wheel Shaft - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, provide a comprehensive framework for the regulation of civil aviation within Australia. One of the key components of this legislative framework is Part 39, which includes specific regulations designed to ensure the airworthiness of aircraft. This includes the issuance of airworthiness directives, such as AD/M20/30 Amendment 2, which addresses the inspection of control wheel shafts in Mooney M20 Series Aeroplanes. This directive was introduced to address the specific problem of potential failure in the control wheel shaft, which could lead to loss of control of the aircraft. The policy objective of this legislation is to ensure the safety of all persons onboard by mandating regular inspections and necessary modifications to maintain the airworthiness of the specified aircraft models. The Mooney M20 Series Aeroplanes airworthiness directive, detailed in Schedule 105 of the Civil Aviation Regulations 1998, applies to all models M20, M20A, M20B, M20C with serial numbers prior to 20-1238, M20D, M20E, M20F with serial numbers prior to 22-1440, and M20G. Compliance with this directive requires inspections within 25 hours of service after achieving 1000 hours of service, and thereafter at intervals not exceeding 500 hours of service until the aircraft is modified in accordance with Mooney Service Bulletin M20-205B. This ensures that any potential issues with the control wheel shaft are identified and rectified in a timely manner, thereby enhancing the overall safety of air travel.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, governs the maintenance and safety requirements for various aircraft, including Mooney M20 series aeroplanes. This particular legislation mandates that certain Mooney M20 models, specifically M20, M20A, M20B, M20C, M20D, M20E, M20F, and M20G, with specific serial numbers, undergo inspection of the control wheel shaft. The directive applies to aeroplanes with serial numbers prior to 20-1238 for certain models and prior to 22-1440 for others. Compliance with these directives necessitates an inspection within 25 hours of time in service following the aircraft reaching 1000 hours of time in service, and subsequently, at intervals not exceeding 500 hours of time in service, until modifications as outlined in Mooney Service Bulletin M20-205B are implemented. The Civil Aviation Regulations, as a Commonwealth instrument, extend their jurisdictional reach across Australia, ensuring that all aircraft operations within the country adhere to these stringent safety standards. The Act does not explicitly state any exclusions or exemptions, suggesting that all specified aircraft within the scope of this legislation must comply with the outlined directives. The application and enforcement of these regulations may be further detailed in subordinate instruments, which provide additional clarification and implementation guidelines.

Key Provisions

The main operative sections of AD/M20/30 Amendment 2, specifically related to Mooney M20 Series Aeroplanes, require detailed inspections of the control wheel shaft. Section 105 details the applicability of these directives to certain Mooney M20 models, specifically M20, M20A, M20B, M20C with serial numbers prior to 20-1238, and M20D, M20E, M20F with serial numbers prior to 22-1440, as well as M20G models. These directives are to be followed in accordance with the Mooney Service Bulletin M20-205B. Compliance with the inspection requirements is mandatory unless the specified inspection has already been completed. The Act imposes several obligations on the parties governed by these directives. Owners and operators of the affected Mooney M20 Series aeroplanes must ensure that the control wheel shaft is inspected within 25 hours of time in service after achieving 1000 hours, and subsequently at intervals not exceeding 500 hours of time in service. This inspection must be performed in line with the guidance provided in Mooney Service Bulletin M20-205B. Failure to comply with these inspection intervals can lead to non-compliance with civil aviation safety standards. Breach of the Civil Aviation Regulations, particularly in relation to the non-compliance with airworthiness directives, can result in significant consequences. While specific penalties are not detailed in the legislative instrument, general civil aviation regulations provide for potential enforcement actions, which may include fines and potential grounding of the aircraft. The severity of the penalties could depend on the extent of non-compliance and the associated risk to aviation safety. Operators found in breach of these directives may face legal repercussions, which could impact their operational licences and overall compliance standing.
