Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, address safety and operational standards within the civil aviation sector. This legislative framework ensures that aircraft and aeronautical products meet stringent safety criteria, overseen by the Civil Aviation Safety Authority (CASA). Specifically, Part 39 - 105 of the Civil Aviation Regulations 1998 provides the authority for CASA to issue Airworthiness Directives (ADs), which are mandatory safety measures for correcting unsafe conditions in aircraft. The ADs are designed to ensure the continued airworthiness of aircraft and protect public safety. The policy objective behind these regulations is to maintain high standards of safety and efficiency in civil aviation, ensuring that all aircraft operate within a robust regulatory environment that prioritises passenger and crew safety.
Scope and Application
The Airworthiness Directive (AD) AD/BAe 146/101 issued under the Civil Aviation Regulations 1998 applies specifically to all Avro 146-RJ70, RJ85, and RJ100 series aeroplanes that have undergone specific modifications, namely HCM01080B and HCM01364D, HCM01364E, or HCM01364F. This directive mandates the modification of the Digital Flight Guidance Computer (DFGC) system in accordance with the specifications outlined in BAe Systems (Operations) Ltd Modification Service Bulletin SB.22-068-70628B dated 4 November 2002, which has been classified as mandatory by the Civil Aviation Authority (UK). The directive stipulates that the required modifications must be completed before 1 May 2005. It is important to note that this directive is issued by the Civil Aviation Safety Authority (CASA) delegate and applies across the Commonwealth of Australia, ensuring that all affected aircraft meet the safety standards set forth by the regulation. The directive became effective on 20 February 2003 and was subsequently notified in the Commonwealth of Australia Gazette on 29 January 2003.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105, details a specific Airworthiness Directive (AD) concerning the Avro 146-RJ70, RJ85, and RJ100 series aeroplanes that have incorporated certain modifications. According to section 39.1 (1) of the CAR 1998, this AD mandates actions to address an unsafe condition identified in the Digital Flight Guidance Computer (DFGC) system of these aircraft (AD/BAe 146/101). The applicability section of the AD specifies that it applies to all Avro 146-RJ70, RJ85, and RJ100 series aeroplanes that have modification HCM01080B and HCM01364D or HCM01364E or HCM01364F incorporated. The requirement section outlines that the DFGC system must be modified in accordance with BAe Systems (Operations) Ltd Modification Service Bulletin SB.22-068-70628B dated 4 November 2002, which has been classified as mandatory by the CAA(UK). The compliance section mandates that these modifications must be completed before 1 May 2005.
The AD imposes specific obligations on aircraft operators and maintenance personnel to ensure that the DFGC system modifications are performed correctly and in a timely manner. Operators must verify that their aircraft meet the applicability criteria and that they obtain and follow the detailed instructions provided in the referenced modification service bulletin. Maintenance personnel must execute the modifications as specified, ensuring the safety and airworthiness of the affected aircraft. Additionally, the AD requires that all modifications be completed and documented prior to the specified compliance date.
Failure to comply with the AD may result in serious consequences. The Civil Aviation Safety Authority (CASA) has the authority to take enforcement actions against operators who fail to adhere to the directive. Potential penalties for non-compliance may include fines, enforcement notices, and other regulatory actions as deemed appropriate by CASA. While the AD does not specify maximum penalties, such consequences can be severe and may include grounding of the aircraft, suspension of operations, or other punitive measures to ensure compliance with safety regulations.
