Overview
The Civil Aviation Regulations 1998, as amended, contain a specific schedule addressing the airworthiness of Airbus Industrie A319, A320, and A321 series aeroplanes. One such regulation is Airworthiness Directive AD/A320/77 concerning the installation of an improved damping rack for the Loral Data Systems Digital Flight Data Recorder (DFDR) F800. This directive was enacted to address potential issues with the DFDR's ability to record necessary data accurately under certain flight conditions, as advised by Airbus Industrie. The directive applies to all A320 and A321 series aeroplanes equipped with the specified DFDR model, unless they have already undergone certain modifications or updates as outlined in Airbus Industrie Service Bulletin A320-31-1088 Revision 2 dated 16 September 1996. The requirement is to install a DFDR rack with improved damping and to reroute the cable harness in accordance with the specified bulletin. This directive aims to ensure the safety and reliability of flight data recording systems, thereby maintaining the overall airworthiness of these aircraft.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 105, governs the safety directives for aircraft operating within Australia. Specifically, Airworthiness Directive AD/A320/77 pertains to Airbus Industrie A319, A320, and A321 series aeroplanes equipped with a Loral Data Systems Digital Flight Data Recorder (DFDR) F800, excluding those already modified by Airbus Industrie modification 24959 or Service Bulletin A320-31-1088 Revision 2 dated 16 September 1996. This directive applies to all relevant aircraft irrespective of their operating location within Australia, ensuring that the safety measures are uniformly enforced. The requirement mandates the installation of a DFDR rack with improved damping and the rerouting of the cable harness as per the specified Airbus Industrie service bulletin. Compliance is mandatory, with an effective date of 30 January 1997, and the changes must be implemented before 31 July 1998. This directive is designed to address potential discrepancies in data recording under certain flight conditions, as identified by Airbus Industrie.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, include an Airworthiness Directive (AD/A320/77) concerning Airbus Industrie A319, A320, and A321 series aeroplanes. This directive addresses the installation of an improved damping rack for the Loral Data Systems Digital Flight Data Recorder (DFDR) F800 (section 1). The requirement outlined in section 2 is to install this improved DFDR rack and reroute the cable harness as per Airbus Industrie Service Bulletin (SB) A320-31-1088 Revision 2 dated 16 September 1996. This action is mandated for all A320 and A321 series aeroplanes equipped with the specified DFDR, excluding those already modified by Airbus Industrie modification 24959 or having SB A320-31-1088 Revision 2. Compliance with this directive must be achieved prior to 31 July 1998, and the directive itself became effective on 30 January 1997 (section 3).
Entities governed by these regulations must ensure that the specified modifications are made to their aircraft by the compliance date. This involves installing the improved DFDR rack and rerouting the cable harness in accordance with the instructions provided in the referenced service bulletin. The directive is applicable to all relevant aircraft unless they have already received the specified modifications (section 4). These obligations are designed to rectify a discrepancy identified by Airbus Industrie, where under certain flight conditions, the DFDR might not record all necessary data correctly (section 5).
Failure to comply with the provisions of this Airworthiness Directive can result in civil or criminal consequences. The regulations stipulate that non-compliance can lead to penalties as prescribed by the Civil Aviation Act 1988, which may include fines or other sanctions. The exact penalties for non-compliance are not explicitly detailed in the directive but are governed by broader civil aviation legislation, which may impose significant financial penalties or other enforcement actions (section 6). Ensuring compliance is crucial for maintaining the airworthiness of the aircraft and the safety of all individuals involved in aviation activities (section 7).
