Overview
The Civil Aviation Regulations 1998 (CAR 1998), enacted by the Australian Government, serve as the primary regulatory framework governing civil aviation within Australia. These regulations are administered by the Civil Aviation Safety Authority (CASA) and are instrumental in ensuring the safety and airworthiness of all civil aircraft operating in Australian airspace. The legislation fills a critical gap by providing detailed standards and requirements necessary for maintaining the safety of civil aviation activities. This legislative instrument specifically addresses the need for ongoing airworthiness assessments and the implementation of safety directives to mitigate any potential risks associated with aircraft operation. CAR 1998 was introduced to streamline and standardise the regulatory oversight of civil aviation, aiming to uphold the highest safety standards in line with international best practices.
Scope and Application
This Airworthiness Directive issued under the Civil Aviation Regulations 1998 applies to all British Aerospace BAe 146 Series 100, 200, and 300 aircraft that have not yet undergone Modification HCM00713A. The directive is issued by the Civil Aviation Safety Authority (CASA) delegate to ensure the continued airworthiness of these aircraft. It requires inspections and modifications to the rear pressure bulkhead horizontal butt joint as specified in BAE Systems Mandatory Service Bulletin 53-42. The AD became effective on 25 January 2001 and is applicable within the Commonwealth of Australia. The directive was published in the Commonwealth of Australia Gazette on 20 December 2000. The AD applies to all BAe 146 Series aircraft within the specified series and condition, and compliance with the directive is mandatory for continued airworthiness. The AD extends its application through subordinate instruments as specified in the requirement and compliance sections.
Key Provisions
The Airworthiness Directive (AD/BAe 146/84) applies to all BAe 146 Series 100, 200, and 300 aircraft that have not yet undergone Modification HCM00713A. This AD requires the inspection and modification of the rear pressure bulkhead horizontal butt joint in accordance with BAE Systems Mandatory Service Bulletin 53-42. The compliance timeline for these actions is specified within the requirement document, detailing both initial and repeat inspection requirements and the modification action needed. It is important to note that the completion of Modification HCM00713A serves as the terminating action for the repeat inspection requirement of this Directive (section 1).
The AD imposes several obligations on the relevant parties. Aircraft operators must ensure that the inspections and modifications are carried out in strict adherence to the instructions provided by BAE Systems Mandatory Service Bulletin 53-42. This includes following the specified timeline for initial and repeat inspections as well as completing the required modification action. The AD mandates that these actions be undertaken to maintain the integrity of the horizontal butt joint at the rear pressure bulkhead, which is critical for the continued airworthiness of the aircraft (section 1).
Failure to comply with the provisions of this AD can lead to serious consequences. The Civil Aviation Safety Authority (CASA) can enforce penalties for non-compliance, which may include substantial fines or other regulatory actions. Although the exact penalties are not specified in the text, the potential consequences underscore the importance of adhering to the AD's requirements. Ensuring compliance is not only a legal obligation but also a critical safety measure to prevent any unsafe conditions that could compromise the aircraft's operational integrity (section 1).
