AD/M20/20 Amdt 1 - Flap Hinges Corrosion

Overview

The Civil Aviation Regulations 1998 (Cth) are a fundamental set of rules established by the Australian Government to govern civil aviation safety. Part 39, which includes the 105th Civil Aviation Safety Authority Schedule of Airworthiness Directives, addresses specific maintenance and operational requirements for certain aircraft models. One such directive, AD/M20/20 Amendment 1, pertains to the Mooney M20 series aeroplanes, specifically targeting corrosion issues in flap hinges. Enacted to ensure the continued airworthiness of Mooney M20C, M20D, M20E, M20F, and M20G models, this amendment was introduced to correct the applicability of the original directive by specifying the relevant serial numbers. The objective of this amendment is to maintain compliance with Mooney Service Bulletin M20-186A, ensuring that inspections and necessary repairs are conducted within 100 hours of time in service after 30 April 1975 and at intervals not exceeding one year thereafter, thereby mitigating the risk of corrosion and enhancing overall aircraft safety.

Scope and Application

The Mooney M20 Series Aeroplanes Airworthiness Directive (AD) applies to all models M20C, M20D, M20E, M20F, and M20G with specific serial numbers as listed in the accompanying Requirement Document. The AD is issued under the Civil Aviation Regulations 1998, specifically within Part 39 - 105, and mandates compliance actions in accordance with Mooney Service Bulletin M20-186A. The geographical reach of this legislation is national, governed by the Commonwealth of Australia, and it applies to the civil aviation industry within Australia. The AD requires compliance within 100 hours of time in service after 30 April 1975 and at intervals not exceeding one year thereafter. This legislation does not explicitly state any exclusions, exemptions, or thresholds, but it may be further defined or extended through subordinate instruments. The AD's primary purpose is to address corrosion issues in the flap hinges of the specified Mooney M20 Series aeroplanes to ensure continued airworthiness and safety.

Key Provisions

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, address the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives for Mooney M20 Series Aeroplanes. Section AD/M20/20 Amendment 1 focuses on flap hinges corrosion, applicable to all models M20C, M20D, M20E, M20F, and M20G with specific serial numbers listed in the Requirement Document (Section 1). The directive mandates compliance with Mooney Service Bulletin M20-186A (Section 3), and requires action to be taken within 100 hours of time in service after 30 April 1975, and thereafter at intervals not exceeding one year (Section 4). The primary obligation under this directive is to ensure that all specified Mooney M20 Series Aeroplanes undergo the necessary checks and repairs to address flap hinges corrosion. This involves adhering to the instructions outlined in Mooney Service Bulletin M20-186A (Section 3). The directive further specifies a timeline for compliance: within 100 hours of time in service following 30 April 1975, and then at intervals not exceeding one year thereafter (Section 4). These requirements are essential to maintaining the airworthiness and safety of the aircraft in question. Failure to comply with the provisions of this Airworthiness Directive can lead to severe consequences. The Civil Aviation Regulations 1998 outline various offences and penalties for non-compliance with CASA directives. Such breaches can result in civil penalties, including fines and potential legal actions against the operators or owners of the aircraft. Additionally, persistent or significant non-compliance could lead to criminal charges, with the potential for imprisonment, reflecting the gravity of ensuring aviation safety standards are met. The maximum penalties for such offences are determined by the severity of the breach and are set out in the broader legislative framework governing civil aviation in Australia.
