AD/M20/34 - Fuel Tank Finger Strainer - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, establish the regulatory framework governing civil aviation safety. This legislative instrument is overseen by the Civil Aviation Safety Authority (CASA) and is integral to ensuring the safety of aircraft operations. One of the specific directives within this broader regulation is the Airworthiness Directive (AD) for Mooney M20 Series Aeroplanes, particularly AD/M20/34 which pertains to the inspection of the fuel tank finger strainer. This directive was introduced to address specific safety concerns related to fuel tank integrity in certain Mooney M20 models, ensuring compliance with safety standards and mitigating potential risks associated with operational failures. The objective is to maintain the airworthiness of these aircraft, thereby protecting both passengers and crew, and contributing to overall aviation safety within Australia.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives (AD) under the Civil Aviation Regulations 1998, specifically AD/M20/34, pertains to the inspection of fuel tank finger strainers in Mooney M20 Series aeroplanes. This directive applies to particular serial numbers of the M20F and M20J models, as detailed in the legislation. The directive is intended to ensure the safety of these aircraft by mandating a thorough inspection of the fuel tank finger strainers to prevent any potential failure that could compromise the integrity of the fuel system. The geographic and jurisdictional reach of this legislation is national, as it applies throughout Australia under the overarching authority of the Civil Aviation Regulations 1998. While the primary focus is on ensuring compliance with the specified inspection requirements, the directive does not explicitly state exclusions, exemptions, or thresholds, suggesting that all applicable aircraft must adhere to the mandate. The enforcement and potential extension of this directive may be further detailed in subordinate instruments, which could provide additional guidelines or clarifications to ensure comprehensive compliance across the specified fleet.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, encompasses the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which includes AD/M20/34 concerning the fuel tank finger strainer inspection for Mooney M20 Series Aeroplanes (sections 1 to 8). This directive applies to specific Mooney M20F and M20J model aeroplanes within particular serial number ranges. It mandates that the fuel tank finger strainer be inspected before 1 December 1978, ensuring compliance with Mooney Service Bulletin No. M20-207. Under the regulations, the entities governed by AD/M20/34, which include aircraft owners, operators, and maintenance providers, must ensure that the specified Mooney M20F and M20J aeroplanes are inspected as per the requirements outlined in Mooney Service Bulletin No. M20-207. This involves a thorough examination of the fuel tank finger strainer to verify its integrity and compliance with the safety standards set forth by CASA. The directive explicitly states that this inspection must be conducted before the compliance deadline of 1 December 1978. Failure to comply with AD/M20/34 can result in serious legal and safety repercussions. The Civil Aviation Regulations 1998 provide that non-compliance with an Airworthiness Directive can lead to civil and criminal penalties. The specific consequences include fines and potential prosecution under the Civil Aviation Act 1988, which can result in significant financial penalties and, in severe cases, imprisonment. The exact penalties can vary depending on the nature and extent of the non-compliance, but they are designed to ensure strict adherence to the safety directives to protect the public and maintain the integrity of civil aviation operations.
