AD/ANSON/23 - Main Undercarriage Radius Rod Tube at Rear Spar Attachment - Inspection

Overview

The Civil Aviation Safety Authority (CASA) has introduced a legislative instrument, F2006B02421, as part of the Civil Aviation Regulations 1998. This legislation, specifically outlined in Part 39 - 105, addresses the safety and airworthiness of Avro Anson and Avro 19 Series Aeroplanes. The enactment of this regulation aims to ensure the maintenance and inspection of the main undercarriage radius rod tube at the rear spar attachment, as stipulated in Avro TSB No. 89. This instrument requires compliance at intervals not exceeding 250 hours of time in service, aiming to enhance the safety standards and operational reliability of these aircraft. The policy objective underpinning this regulation is to mitigate potential risks associated with the structural integrity of the specified components, thereby safeguarding the overall safety of civil aviation activities. The enactment of F2006B02421 by CASA under the Civil Aviation Regulations 1998, reflects a commitment to maintaining stringent safety protocols within the aviation industry. By mandating regular inspections of the main undercarriage radius rod tube at the rear spar attachment, the legislation addresses identified vulnerabilities that could compromise the structural integrity and safety of Avro Anson and Avro 19 Series Aeroplanes. This proactive approach is designed to prevent in-flight failures and ensure that aircraft continue to meet the high standards of safety and reliability required in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, as amended, encompass a range of requirements under the Australian Civil Aviation Safety Authority (CASA), with Part 39 specifically addressing airworthiness directives. The scope of these directives applies to specific types of aircraft, such as the Avro Anson and Avro 19 Series aeroplanes, ensuring that these aircraft meet the necessary safety standards. This legislation mandates compliance with the Airworthiness Directive AD/ANSON/23, which requires inspection of the main undercarriage radius rod tube at the rear spar attachment at intervals not exceeding 250 hours of time in service, as referenced in Avro Technical Standard Order (TSB) No. 89. This regulation applies to the aircraft operators and maintenance providers who are responsible for ensuring the aircraft's compliance with safety standards. The geographic and jurisdictional reach of these regulations is national, applying across all states and territories within Australia. This legislation does not specify any exclusions, exemptions, or thresholds beyond the prescribed inspection intervals. The application of these regulations is further extended or restricted through subordinate instruments issued by CASA, which may provide additional details or clarifications on the implementation of the airworthiness directives.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. Section AD/ANSON/23 concerns the Avro Anson and Avro 19 series aeroplanes, focusing on the main undercarriage radius rod tube at the rear spar attachment. The directive mandates that an inspection of this component be carried out at intervals not exceeding 250 hours of time in service, as outlined in Avro Technical Service Bulletin No. 89. This requirement ensures the structural integrity and continued airworthiness of the specified aircraft. Under these regulations, operators and owners of the Avro Anson and Avro 19 series aeroplanes have the obligation to adhere to the specified inspection intervals. This involves ensuring that the main undercarriage radius rod tube at the rear spar attachment is examined and assessed at the prescribed intervals to meet safety standards. Failure to comply with these requirements may result in non-compliance with CASA’s airworthiness directives, potentially leading to the grounding of the aircraft until the necessary inspections and repairs are conducted. The regulations impose penalties for non-compliance with the airworthiness directives. Specifically, breaches of these inspection requirements can lead to significant civil and criminal consequences. Under the Civil Aviation Act 1988, non-compliance can result in enforcement actions, including fines and potential prosecution. The maximum penalties for non-compliance can be substantial, reflecting the critical nature of ensuring aircraft airworthiness and the safety implications of any lapses in adherence to these directives. It is imperative for operators to maintain strict records of compliance and ensure that all required inspections are performed within the stipulated timeframes to avoid these severe repercussions.
