COMMONWEALTH OF AUSTRALIA (Civil Aviation 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/A320/129 and issues the following AD under subregulation 39.1 (1) of CAR 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/A320/129
Amdt 1
Parking Brake Operating Valve 5/2002
Applicability: Airbus A319, A320 and A321 aeroplanes as specified in DGAC AD 2001-384(B)R1. Requirement: Action per DGAC AD 2001-384(B) R1.
Compliance: As detailed in the requirement document with a revised effective date of 16 May 2002.
This Amendment becomes effective on 16 May 2002.
Background: Airbus Industrie has advised that certain Messier Bugatti parking brake operating valves are susceptible to leakage of hydraulic fluid. This could lead to depletion of the Yellow hydraulic system fluid and render the Alternate Braking and Emergency Braking System inoperative.
This amendment requires the repair or replacement of the affected components by 31 December 2002.
The original issue of this directive became effective on 24 October 2001.

Delegate of the Civil Aviation Safety Authority 27 March 2002
The above AD is notified in the Commonwealth of Australia Gazette on 24 April 2002.
Overview
The Civil Aviation Regulations 1998, established by the Parliament of Australia, form a comprehensive regulatory framework for civil aviation within the country. These regulations, administered by the Civil Aviation Safety Authority (CASA), are essential for ensuring the safety and efficiency of civil aviation operations. One particular legislative instrument, F2006B01876, pertains to Airworthiness Directives under Part 39 of the Civil Aviation Regulations. This instrument addresses the identified safety concerns regarding specific aircraft models, particularly the Airbus A319, A320, and A321 series aeroplanes. The problem it targets is the potential leakage of hydraulic fluid from the Messier Bugatti parking brake operating valves, which could compromise critical braking systems. The directive mandates corrective actions to mitigate this risk, ensuring the continued airworthiness of these aircraft and protecting public safety. The policy objective is clearly to maintain the highest standards of aviation safety through proactive regulatory measures.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39, addresses airworthiness directives to ensure the safety of aircraft and aeronautical products within the Australian jurisdiction. This particular Airworthiness Directive (AD) applies to Airbus A319, A320, and A321 aeroplanes, focusing on the rectification of issues with the parking brake operating valve. The directive mandates corrective actions to address potential leakage of hydraulic fluid, which could compromise the aircraft's braking systems. The AD is issued under the authority of a delegate from the Civil Aviation Safety Authority (CASA) and mandates compliance with the specified requirements and timelines, effective from 16 May 2002. The directive's applicability is national, ensuring that all relevant aircraft within Australia must adhere to the stipulated safety measures. The AD also outlines compliance details and the necessity for repair or replacement of affected components by 31 December 2002 to ensure the continued airworthiness of these aircraft.
Key Provisions
The Civil Aviation Regulations 1998, specifically under Part 39 – 105, mandate the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA) delegate. Section 39.1(1) provides the authority to issue such directives. The latest AD, AD/A320/129 Amendment 1, targets Airbus A319, A320, and A321 series aeroplanes and addresses the issue of parking brake operating valve leakage, as specified in DGAC AD 2001-384(B) R1. This directive revokes the previous AD/A320/129 and sets forth new requirements for addressing the identified safety concern.
Under the AD, operators of the affected Airbus aircraft must follow specific instructions to repair or replace the parking brake operating valves to prevent hydraulic fluid leakage. This action is crucial to maintain the integrity of the Yellow hydraulic system, which is essential for the proper functioning of the Alternate Braking and Emergency Braking Systems. The compliance section dictates that these measures must be undertaken by 31 December 2002, aligning with the revised effective date of the directive, which was initially effective from 24 October 2001.
Operators governed by this AD are obligated to ensure that the specified repairs or replacements are carried out in accordance with the instructions provided within the directive. Failure to comply with these requirements may result in the aircraft being deemed non-airworthy, which could lead to grounding and potential legal repercussions. Ensuring adherence to the directive is essential to maintain the safety standards set by CASA.
Non-compliance with the AD could result in significant consequences, including civil penalties. Under the Civil Aviation Act 1988, failure to adhere to an AD may lead to enforcement actions by CASA, which can include fines and other penalties. The maximum penalties for such breaches are substantial, reflecting the importance of air safety and the critical nature of the directive. The Civil Aviation Regulations 1998 further reinforce the mandatory compliance, underscoring the severe implications of neglecting these safety measures.
