AD/ANSON/22 - Mainplane Spar Boom Joints - Inspection

Overview

The Civil Aviation Regulations 1998, amended by the legislative instrument F2006B02420, were enacted to ensure the safety and regulation of civil aviation within Australia. The regulations, overseen by the Civil Aviation Safety Authority, address specific safety concerns and operational standards for aircraft, including maintenance and inspection protocols. This particular legislative instrument was introduced to fill a gap in ensuring the airworthiness of Avro Anson and Avro 19 series aeroplanes by mandating specific inspections and maintenance of mainplane spar boom joints. The policy objective outlined in the text is to ensure compliance with technical service bulletins, such as Avro TSB No. 88, by requiring inspections before the issuance of a Certificate of Airworthiness and at regular intervals thereafter. This regulatory approach aims to maintain the structural integrity and safety of these aircraft in operation.

Scope and Application

The Civil Aviation Safety Authority (CASA) Regulations 1998, specifically Part 39 - 105, pertain to the airworthiness directives for the Avro Anson and Avro 19 series aeroplanes, with a particular focus on the mainplane spar boom joints. This legislation applies directly to all operators and owners of these specific aircraft models, ensuring that maintenance and inspection standards are met to guarantee their safe operation. The regulations mandate that inspections must be conducted before the issue of a Certificate of Airworthiness (C of A) and at intervals not exceeding five years, while bolt replacement must occur before the issue of a C of A. The scope of this legislation is geographically and jurisdictionally confined to the Commonwealth of Australia, as CASA operates under federal authority. There are no stated exclusions, exemptions, or specific thresholds outlined within this directive; however, the regulations can be further extended or restricted through subordinate instruments issued by CASA. These instruments allow for more detailed and specific application of the overarching airworthiness directives, ensuring compliance with the highest safety standards.

Key Provisions

The Civil Aviation Regulations 1998 (Cth), specifically Part 39, Section 105, establish a schedule of airworthiness directives that mandate the maintenance and inspection of certain aircraft to ensure safety. Under this schedule, Airworthiness Directive AD/ANSON/22 pertains to the Avro Anson and Avro 19 series aeroplanes, focusing on the inspection and maintenance of mainplane spar boom joints. This directive is codified in the Civil Aviation Safety Authority (CASA) regulations and is referenced in Avro Technical Service Bulletin No. 88 (TSB No. 88). In accordance with Section 105, the applicable aircraft must undergo a comprehensive inspection of the mainplane spar boom joints before the issuance of a Certificate of Airworthiness (C of A) and at intervals not exceeding five years thereafter. Additionally, bolts within these joints must be replaced before the issuance of the C of A. This requirement ensures that the structural integrity of the aircraft is maintained, thereby preventing potential failures that could compromise safety. The obligations imposed by this directive are clear and stringent. Operators of Avro Anson and Avro 19 series aeroplanes must adhere to the specified inspection and maintenance schedules to ensure compliance with CASA regulations. Failure to comply with these requirements can result in the suspension or revocation of the aircraft's Certificate of Airworthiness, effectively grounding the aircraft until the necessary inspections and repairs are completed. Failure to comply with the provisions of AD/ANSON/22 can result in significant civil and criminal consequences. Under the Civil Aviation Act 1988 (Cth), non-compliance with airworthiness directives can lead to penalties, including fines and imprisonment. The specific penalties for breaching this directive are not detailed in the legislative text, but penalties for non-compliance with similar provisions can include substantial fines and imprisonment for up to two years. Additionally, CASA has the authority to initiate legal proceedings against operators who fail to comply with airworthiness directives, further emphasising the importance of adhering to these safety requirements.
