AD/A320/64 - Avionics Hatch 231 AF.

Overview

The Civil Aviation Regulations 1998, as amended, form the principal legislation governing aviation safety in Australia, administered by the Civil Aviation Safety Authority (CASA). Within this legislative framework, Part 39, particularly the Airworthiness Directive AD/A320/64, addresses specific maintenance requirements for Airbus Industrie A319, A320, and A321 series aeroplanes. This directive was introduced to ensure safety by preventing the ingress of liquids into the avionics compartment, which could potentially lead to electrical faults or system failures. The objective of this directive is to maintain the airworthiness of these aircraft by mandating compliance with Airbus Industrie Service Bulletin A320-53-1070 before 30 September 1997. The directive references the French civil aviation authority's AD 96-011-075(B) for further context, ensuring a standardised approach to addressing this safety issue across jurisdictions. The Civil Aviation Regulations 1998 were enacted by the Australian Parliament and are administered by CASA, which is responsible for ensuring compliance with airworthiness standards. The specific directive AD/A320/64 was issued to mitigate the risk of liquid ingress into the avionics compartment, which could compromise the safety and operational integrity of the aircraft. The directive applies to all models of Airbus Industrie A319, A320, and A321 series aeroplanes unless they have already incorporated modifications 22119 or 21999, or Service Bulletin A320-53-1070. This requirement mandates adherence to the specified action to ensure the safety and reliability of the aircraft's avionics systems.

Scope and Application

The Civil Aviation Regulations 1998, as amended, under the jurisdiction of the Civil Aviation Safety Authority, includes specific Airworthiness Directives governing the operation and maintenance of certain aircraft models. One such directive, AD/A320/64, applies to Airbus Industrie A319, A320 and A321 series aeroplanes that do not have modifications 22119 or 21999 embodied, or Service Bulletin A320-53-1070 incorporated. This directive mandates compliance with Airbus Industrie Service Bulletin A320-53-1070, which is referenced in DGAC AD 96-011-075(B). The directive aims to prevent the entry of spilled liquids into the avionics compartment via the hatch seal, with a compliance requirement before 30 September 1997. The regulations ensure that the safety and airworthiness of the specified aircraft models are maintained in accordance with the specified standards, thereby safeguarding the integrity of the avionics systems and ensuring the safety of the aircraft operations.

Key Provisions

The Civil Aviation Regulations 1998, particularly in PART 39 - 105, include specific Airworthiness Directives (AD) that govern the safety and operational standards of aircraft. For Airbus Industrie A319, A320, and A321 series aeroplanes, one such directive is AD/A320/64, which pertains to the avionics hatch (231 AF) (s. 105). This directive is applicable to all models of these aircraft series that do not have modifications 22119 or 21999 incorporated or the Service Bulletin A320-53-1070 implemented. The directive mandates that operators must take corrective action in accordance with the Airbus Industrie Service Bulletin A320-53-1070 (s. 105). This action is necessary to prevent any liquids from spilling into the avionics compartment through the hatch seal. Operators of Airbus Industrie A319, A320, and A321 series aeroplanes must adhere to the requirements set forth in AD/A320/64. Specifically, they must ensure that any aircraft falling under the directive's applicability undergo the corrective measures detailed in the Airbus Industrie Service Bulletin A320-53-1070 (s. 105). This requirement aims to maintain the integrity of the avionics compartment and prevent potential damage from liquid ingress. Additionally, the directive references DGAC AD 96-011-075(B) for further guidance on compliance (s. 105). It is imperative that these actions are completed prior to 30 September 1997 to ensure the aircraft's continued airworthiness. Failure to comply with the provisions of AD/A320/64 could result in severe consequences. The Civil Aviation Regulations 1998 impose significant obligations on operators to ensure their aircraft meet the specified airworthiness standards. Non-compliance with the directive could lead to penalties under the relevant sections of the Act, including fines or other enforcement actions. The specific penalties for breach of these regulations are not detailed within the text of the directive but would typically involve administrative or legal action under the broader framework of the Civil Aviation Act 1988 and associated regulations. The potential civil or criminal consequences underscore the importance of adhering to these safety directives to maintain the highest standards of aviation safety.
