COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Background: Investigation into an incident involving an A320 aircraft showed that seizure of the alternate brake valve distribution body (BDDV) had been caused by water ingress into the valve. The measures introduced by the initial issue of this Directive provides inspection and operational tests to prevent a dormant in-flight failure of the alternate braking system pending the release of a permanent modification.
Amendment 1 has been raised to provide terminating action for this Airworthiness Directive.
The original issue of this Airworthiness Directive became effective on 22 April 1999.
Eugene Paul Holzapfel
Delegate of the Civil Aviation Safety Authority 5 May 2000
The above AD is notified in the Commonwealth of Australia Gazette on 17 May 2000.
Overview
The Civil Aviation Regulations 1998, as amended, includes the Airworthiness Directives for the Airbus Industrie A319, A320 and A321 series aeroplanes, addressing specific safety concerns identified in the aviation sector. Enacted by the Civil Aviation Safety Authority (CASA) under the authority of the Civil Aviation Act 1988, this legislation aims to mitigate risks associated with aircraft operations by mandating safety improvements and corrective actions. The policy objective is to ensure the continued airworthiness of aircraft through timely and effective regulatory action, thereby protecting public safety and maintaining high standards of aviation safety in Australia. This Airworthiness Directive, specifically AD/A320/96 Amendment 1, was introduced to address an unsafe condition identified in the alternate braking system of certain Airbus aircraft models, thereby preventing potential in-flight failures and ensuring the safe operation of these aircraft.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES, applies to all Airbus Industrie model A319, A320 and A321 aircraft. This regulation mandates specific actions to address identified safety concerns related to the alternate braking system of these aircraft. For aircraft that have not implemented Modification 27833 or Airbus Industrie Service Bulletin A320-32-1200, the regulation requires a functional test and necessary maintenance tasks as per Airbus Industrie AOT 32-19. Conversely, for aircraft that have implemented these modifications, an inspection as defined in Airbus Industrie Service Bulletin A320-32-1199 is required. Furthermore, all inspection results must be reported to Airbus Industrie, and the requirements of Airbus Industrie Service Bulletin A320-32-1203 must be incorporated. This directive aims to prevent in-flight failures of the alternate braking system due to water ingress into the brake valve distribution body. Compliance with these directives is mandatory and must be adhered to within specified timeframes, as detailed in the regulation.
Key Provisions
The Airworthiness Directive (AD) AD/A320/96 Amendment 1 issued by the Civil Aviation Safety Authority (CASA) under subregulation 39.1(1) of the Civil Aviation Regulations 1998 (CAR 1998) specifically targets Airbus Industrie A319, A320, and A321 series aeroplanes. This directive revokes the previous AD/A320/96 and outlines new requirements to address safety concerns with the alternate braking system of these aircraft. The directive mandates specific actions for the maintenance and inspection of the alternate braking system, depending on whether certain modifications or service bulletins have been implemented. The directive applies to all A319, A320, and A321 aircraft.
For aircraft that have not implemented Modification 27833 or Airbus Industrie Service Bulletin A320-32-1200, the AD requires performing a functional test and any necessary maintenance tasks as detailed in Airbus Industrie AOT 32-19 at Revision 1, 2, or 3. For aircraft that have implemented either Modification 27833 or Airbus Industrie Service Bulletin A320-32-1200, an inspection as per Airbus Industrie Service Bulletin A320-32-1199 must be conducted. Additionally, the results of all inspections must be reported to Airbus Industrie, and the requirements of Airbus Industrie Service Bulletin A320-32-1203 must be incorporated. The directive will be terminated if either Modification 27833 or Airbus Industrie Service Bulletin A320-32-1203 is implemented.
The AD imposes specific obligations on the operators of the affected aircraft. Operators must ensure that the required inspections and maintenance tasks are performed in accordance with the directive. This includes conducting the specified functional tests and inspections at the prescribed intervals, reporting inspection results, and implementing any necessary modifications or service bulletins. Operators must also ensure compliance with the timelines set out in the directive, such as performing the initial actions within a week and subsequent actions every six months.
Failure to comply with the AD can result in significant consequences. While the AD does not explicitly state penalties, non-compliance with CASA directives can lead to enforcement actions under the Civil Aviation Act 1988. Potential consequences include fines, operational restrictions, and in severe cases, grounding of the aircraft. The specific penalties would depend on the nature and severity of the non-compliance, as well as any resulting safety risks. Operators are expected to adhere strictly to the directive to maintain the airworthiness of the aircraft and ensure the safety of passengers and crew.
