AD/A320/109 Amdt 1 - MLG Door Actuator Fitting

Overview

The Civil Aviation Safety Regulations 1998, enacted by the Australian Government, establish a comprehensive framework for ensuring the safety of civil aviation within Australia. These regulations, overseen by the Civil Aviation Safety Authority (CASA), provide the necessary legal basis for the implementation of airworthiness directives (ADs), which are essential in maintaining the safety of aircraft and aeronautical products. One such AD is AD/A320/109, which addresses a specific safety concern identified with the Airbus Industrie A319, A320, and A321 series aeroplanes. This AD was introduced to rectify an unsafe condition related to the main landing gear door actuator fittings, as identified by further investigation into potential cracks in the upper part of the door actuator fitting in the area of the hinge. The AD was issued by a delegate of the Civil Aviation Safety Authority and is aimed at ensuring that all necessary actions are taken to maintain the airworthiness of the affected aircraft.

Scope and Application

The Civil Aviation Safety Regulations 1998, specifically under Part 39 - 105 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives, outlines mandatory actions to ensure the safety of civil aviation operations. This particular Airworthiness Directive, AD/A320/109 Amendment 1, applies to Airbus Industrie A319, A320, and A321 series aeroplanes equipped with specific main landing gear door fittings assembly parts. The directive targets aircraft that have particular production modifications or service bulletins incorporated into service but excludes those that have already replaced the landing gear door. The requirement for compliance is detailed in the directive and necessitates adherence to the actions specified by the Direction Générale de l'Aviation Civile (DGAC) AD F-2003-434, issued on 10 December 2003. The directive became effective from 19 February 2004 and is published in the Commonwealth of Australia Gazette on 28 January 2004. This legislative instrument underscores the importance of regular safety inspections and maintenance actions to ensure the airworthiness of specific aircraft models.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CASR), specifically Part 39 - 105, address the issuance and management of Airworthiness Directives (ADs) to ensure the safe operation of aircraft. Under section 39.1(1), the delegate of the Civil Aviation Safety Authority (CASA) has the authority to issue ADs, which are legally binding orders that mandate specific actions to be taken to address safety concerns identified in aircraft or aeronautical products. In this instance, the CASA delegate has revoked AD/A320/109 and issued a new directive (AD/A320/109 Amdt 1) that applies to Airbus Industrie A319, A320, and A321 series aeroplanes with certain main landing gear door fittings. The directive requires that the action specified in the requirement section be taken under the conditions outlined in the applicability section and within the timeframe provided in the compliance section. The AD/A320/109 Amdt 1 applies to A319, A320, and A321 aircraft equipped with specific main landing gear door fittings assembly parts (D52880224 00/001 or D52880235 00/001). Aircraft that have incorporated specific modifications (Modification 24903 or 25372) or service bulletins (A320-52-1073 original issue, Revision 1, 2, 3, or 4) and have not had any landing gear door replacements are exempt from this directive. The requirement outlined in the AD mandates action in accordance with DGAC AD F-2003-434, issued on 10 December 2003. This action must be carried out as specified in the requirement document and comply with the timeframe provided. The compliance section indicates that the amendment becomes effective on 19 February 2004. Failure to comply with the AD/A320/109 Amdt 1 could result in serious safety implications and potential legal consequences. The AD is a legally binding order, and non-compliance may lead to civil or criminal penalties. Under the CASR, non-compliance with an AD can result in substantial fines and potential prosecution. The specific penalties for breach of an AD are not detailed in the legislative instrument but are outlined in other sections of the CASR, where penalties can include fines up to $222,200 for individuals and $1,111,000 for corporations, along with potential imprisonment for serious offences. The enforcement of compliance is critical to maintaining the safety standards required for civil aviation operations in Australia.
