AD/M20/7 Amdt 1 - Landing Gear Warning System - Modification

Overview

The Civil Aviation Regulations 1998, as amended by the Legislative instrument F2006B11259, address the necessity for ensuring the continued airworthiness of Mooney M20 series aeroplanes, specifically those models M20C, M20D, and M20E fitted with electrically operated landing gear. Enacted by the Commonwealth of Australia, this legislation under PART 39 - 105 mandates the modification of the landing gear warning system to enhance flight safety and mitigate risks associated with the operation of these aircraft. The policy objective is to ensure that all specified Mooney M20 series aeroplanes meet stringent safety standards, thereby protecting both passengers and crew, and maintaining the overall integrity of Australia’s civil aviation safety framework.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the safety standards and operational requirements for civil aviation in Australia, and under this, the Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (ADs) to ensure the safety of aircraft. AD/M20/7 Amendment 1 pertains to the Mooney M20 Series Aeroplanes, particularly models M20C, M20D, and M20E, that are fitted with electrically operated landing gear. This directive mandates modifications to the landing gear warning system to enhance safety standards, requiring compliance forthwith. The directive applies to all relevant Mooney M20 aircraft within Australia, ensuring adherence to the specified modifications to maintain airworthiness. This particular legislative instrument is jurisdictional in scope, applying across the Commonwealth of Australia and enforced by CASA. The directive sets clear requirements for the specified Mooney M20 aircraft models and does not include any stated exclusions or exemptions. Compliance with the AD is mandatory for all operators and owners of the affected aircraft, ensuring that the safety improvements are implemented to prevent potential hazards associated with the landing gear warning system. Additionally, the Civil Aviation Regulations may extend or restrict the application of such directives through subordinate instruments, providing further clarity and enforcement mechanisms.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, includes a schedule of airworthiness directives for various aircraft types, including the Mooney M20 series aeroplanes. One such directive, AD/M20/7 Amendment 1, pertains to the landing gear warning system for models M20C, M20D, and M20E that are fitted with electrically operated landing gear (section 5/67). This directive requires all affected aircraft to comply with the modifications specified in Mooney VB 20-130 to ensure the safety of the landing gear warning system. Operators and owners of the Mooney M20 series aeroplanes must ensure that the required modifications to the landing gear warning system are carried out without delay. This involves following the detailed instructions and specifications provided in the referenced document, Mooney VB 20-130. Compliance with this directive is mandatory, and failure to implement the required modifications may result in the aircraft being deemed non-airworthy. Failure to comply with the airworthiness directive AD/M20/7 Amendment 1 could lead to severe consequences. The Civil Aviation Safety Authority (CASA) may impose penalties for non-compliance, which can include fines and potential grounding of the aircraft. The severity of the penalties depends on the extent of non-compliance and any resulting safety risks. Operators and owners must be aware that ongoing operation of an aircraft without the required modifications may also result in enforcement actions under the Civil Aviation Act 1988.
