AD/A320/56 - Centre Wing, Pressurised Floor Fittings at Frame 36

Overview

The Civil Aviation Regulations 1998 (Cth) were enacted to provide comprehensive regulations for civil aviation safety in Australia, addressing gaps in ensuring safe air travel and operational standards. Specifically, Part 39 - 105 of these regulations includes Airworthiness Directives designed to maintain the airworthiness of aircraft. One such directive, AD/A320/56, pertains to Airbus Industrie A319, A320, and A321 series aeroplanes, focusing on the pressurised floor fittings at Frame 36. This directive was introduced by the Civil Aviation Safety Authority under the authority granted by the Civil Aviation Act 1988 (Cth), aiming to detect and prevent any structural damage related to fatigue. The policy objective is to ensure that these aircraft remain safe and airworthy throughout their operational life by mandating regular inspections and maintenance in accordance with specified intervals.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Australian Civil Aviation Safety Authority (CASA) issuing airworthiness directives for particular aircraft models. This includes Airbus Industrie A319, A320, and A321 series aeroplanes, with the directive AD/A320/56 focusing on the centre wing pressurised floor fittings at Frame 36. The directive applies to the specified aircraft models within the scope of the Requirement Document and is designed to ensure the structural integrity of these planes by preventing any damage associated with structural fatigue. The directive mandates actions in accordance with Airbus Industrie SB A320-57-1028 and references the DGAC AD 95-099-067(B) for compliance guidelines. The requirement necessitates compliance prior to the aircraft attaining 16,000 flight cycles and subsequently at the intervals specified in the Requirement Document. Notably, full incorporation of Airbus Industrie SB A320-57-1029 will supersede this directive. The geographic and jurisdictional reach of this directive is national, as it applies throughout Australia under the authority of CASA. The directive applies to entities operating Airbus Industrie A319, A320, and A321 series aeroplanes within Australia, ensuring that these aircraft meet the specified airworthiness standards. While the directive itself does not explicitly mention exclusions, exemptions, or thresholds beyond the specified aircraft models and flight cycles, it is implied that the requirements are tailored to the operational context and maintenance schedules of these aircraft. The directive can be extended or restricted through subordinate instruments issued by CASA, ensuring the regulations are updated in line with evolving safety standards and technological advancements.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Subpart 105, contains the Airworthiness Directives (AD) concerning various aircraft types, including Airbus Industrie A319, A320, and A321 series aeroplanes. This particular directive, AD/A320/56, pertains to the centre wing pressurised floor fittings at Frame 36. The directive mandates action in accordance with Airbus Industrie Service Bulletin (SB) A320-57-1028. For reference, it also notes the French DGAC AD 95-099-067(B). The directive applies to aircraft before they reach 16,000 flight cycles and requires compliance thereafter at intervals specified in the Requirement Document. The directive is intended to detect and prevent damage related to structural fatigue, and it is terminated by the full incorporation of Airbus Industrie SB A320-57-1029. The obligations under this directive include ensuring that the aircraft's centre wing pressurised floor fittings at Frame 36 are inspected and maintained according to the instructions outlined in Airbus Industrie SB A320-57-1028. The compliance must be achieved prior to the aircraft reaching 16,000 flight cycles, and continued compliance is required at the intervals specified in the Requirement Document. Failure to adhere to these obligations could result in the aircraft being deemed non-airworthy, which would prevent it from operating legally. Breaches of these obligations can lead to significant consequences. Under the Civil Aviation Regulations 1998, failure to comply with an Airworthiness Directive can result in both civil and criminal penalties. Civil penalties can include fines and the potential grounding of the aircraft. Criminal penalties can include imprisonment, with the specific maximum penalties depending on the severity and intent of the breach. The regulations are designed to ensure the safety of all passengers and crew by enforcing stringent compliance with airworthiness standards.
