COMMONWEALTH OF AUSTRALIA (Civil Aviation Safety Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/A320/42 and issues the following AD under subregulation 39.1 (1) of CASR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Airbus Industrie A319, A320 and A321 Series Aeroplanes
AD/A320/42
Amdt 1
Brake Wear Limits 1/2004
Applicability: Model A320 series aircraft equipped with Messier-Bugatti, BFGoodrich, Allied Signal Aerospace Company (Bendix), or Aircraft Braking Systems brakes; as specified in FAA AD 97-02-04.
Requirement: 1. Inspect, and replace the main landing gear brakes where necessary, in accordance with the appropriate maximum wear limits specified in FAA AD 97-02-04.
2. Incorporate the appropriate wear limits into the aircraft’s approved system of maintenance.
Compliance: Prior to 30 August 1995.
The compliance time remains unchanged by this issue. This Amendment becomes effective on 22 January 2004.
Background: This Directive was raised to ensure there is no loss of brake effectiveness during a high energy rejected take-off (RTO).
Amendment 1 is issued to clarify applicability and to introduce the current FAA AD.
The original issue of this Airworthiness Directive became effective on 30 August 1995.

Overview
The Civil Aviation Safety Regulations 1998, enacted by the Parliament of Australia, provide a comprehensive framework for ensuring the safety of civil aviation operations within the country. A specific component of this regulatory structure is Part 39 - 105, which concerns the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. These directives are critical in addressing safety issues that may arise in the operation of aircraft. The Airworthiness Directive AD/A320/42 Amendment 1, focusing on brake wear limits for Airbus Industrie A319, A320, and A321 series aeroplanes, exemplifies the proactive measures taken by CASA to mitigate potential risks. The primary objective of this directive is to ensure that brake effectiveness is maintained, particularly during high-energy rejected take-offs, thereby enhancing overall flight safety. This directive was issued to address concerns about brake wear and to incorporate the latest FAA standards, as reflected in FAA AD 97-02-04, into the maintenance protocols of affected aircraft.
Scope and Application
The Airworthiness Directive AD/A320/42 issued under the Civil Aviation Safety Regulations 1998 applies specifically to Airbus Industrie A320 series aircraft that are equipped with Messier-Bugatti, BFGoodrich, Allied Signal Aerospace Company (Bendix), or Aircraft Braking Systems brakes, as detailed in FAA AD 97-02-04. This directive is enforced by the Civil Aviation Safety Authority (CASA), a Commonwealth body, ensuring its reach across the entire national jurisdiction of Australia. The primary requirement of the directive is to inspect and replace the main landing gear brakes as necessary, adhering to the maximum wear limits specified in FAA AD 97-02-04, and to incorporate these wear limits into the aircraft's approved maintenance system. Compliance with this directive must be achieved before 30 August 1995, and the amendment to this directive, issued on 22 January 2004, provides further clarification and aligns with the FAA’s guidelines. This legislative instrument aims to mitigate the risk of brake failure during high energy rejected take-offs, thereby enhancing the safety standards for civil aviation in Australia.
Key Provisions
The main operative sections of this Airworthiness Directive (AD) under the Civil Aviation Safety Regulations 1998 (CASR) involve the specific requirements for maintaining and ensuring the airworthiness of Airbus Industrie A320 series aeroplanes equipped with certain brake systems. Section 1 of the AD specifies the applicability, detailing that it applies to A320 series aircraft equipped with Messier-Bugatti, BFGoodrich, Allied Signal Aerospace Company (Bendix), or Aircraft Braking Systems brakes, as outlined in FAA AD 97-02-04. Section 2 of the AD sets the requirements, which include inspecting and replacing the main landing gear brakes in accordance with the maximum wear limits specified in FAA AD 97-02-04, and incorporating these wear limits into the aircraft’s approved maintenance system. The compliance section mandates that these actions be taken prior to 30 August 1995, with the amendment becoming effective on 22 January 2004.
This AD imposes specific obligations on the operators and maintainers of the affected aircraft. They must inspect and, if necessary, replace the main landing gear brakes in line with the wear limits specified in FAA AD 97-02-04. Additionally, operators must integrate these wear limits into their approved maintenance systems. These obligations ensure that the brake systems on the A320 series aircraft are maintained to a standard that prevents any loss of brake effectiveness, particularly during critical phases of flight such as a rejected take-off. The AD also requires that these actions be documented and that compliance is verified by the Civil Aviation Safety Authority (CASA).
Failure to comply with the requirements of this AD can lead to significant consequences. The AD does not explicitly state the penalties for non-compliance, but under CASR 1998, failure to comply with an AD can result in enforcement actions by CASA, including fines and potential grounding of the aircraft. Such actions are intended to ensure that aircraft operate safely and that any identified unsafe conditions are promptly addressed. The exact penalties for non-compliance may vary, but they can be severe, reflecting the importance of adhering to airworthiness directives to prevent potential safety risks.
