AD/DH114/23 - Fin Attachment Brackets - Inspection

Overview

The Civil Aviation Safety Authority (CASA) introduced Airworthiness Directive (AD) DH114/23 for the Heron Series Aeroplanes to address safety concerns associated with the fin attachment brackets of these aircraft. Enacted under the authority of the Civil Aviation Act 1988, the directive was issued to ensure that all models of the DH114 series undergo regular inspections of the fin attachment brackets as per the specified compliance requirements outlined in the Hawker Siddeley TNS Heron (114) document, Issue 2. This legislative instrument aims to enhance aviation safety by mitigating risks related to structural integrity, ensuring that these aircraft meet the necessary safety standards before continuing operations. The directive reflects the Australian Government's commitment to maintaining high safety standards in civil aviation, overseen by CASA as part of their regulatory function.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, pertains to the Hawker Siddeley TNS Heron (DH114) series aeroplanes, with AD/DH114/23 detailing the fin attachment brackets inspection requirements. This legislative instrument applies to all models of the Heron series aeroplanes, ensuring that compliance is maintained with the specifications outlined in the requirement document. The regulations govern the inspection procedures necessary to maintain the airworthiness of these aircraft, thereby ensuring safety standards are upheld across the industry. The scope of this legislation extends across the Commonwealth of Australia, impacting operators and owners of the Heron series aeroplanes. The regulation does not specify any exclusions or exemptions, implying that all affected aircraft must adhere to the outlined inspection requirements. The application of these directives may be further detailed or expanded through subordinate instruments, which could include additional clarifications or operational guidelines necessary to implement the AD/DH114/23 effectively.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, particularly Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, pertain to the maintenance and inspection of specific aircraft models. In this case, AD/DH114/23 pertains to the Heron Series Aeroplanes, specifically the fin attachment brackets (section 39-105). The directive mandates a thorough inspection of these brackets, with compliance expected as per the detailed requirements outlined in the Hawker Siddeley TNS Heron (114) No. F.15, Issue 2 (section 39-105). These sections establish the parameters and procedures for ensuring the aircraft remain airworthy. The obligations and requirements imposed by these regulations are stringent and multifaceted. Operators of Heron Series Aeroplanes must conduct regular inspections of the fin attachment brackets, as mandated by the directive. This involves a meticulous examination to ensure that there are no defects, wear, or damage that could compromise the structural integrity of the fin (section 39-105). These inspections must be performed by certified personnel who are trained and authorised to carry out such tasks, ensuring that the highest standards of safety and compliance are upheld. Records of all inspections must be maintained and made available for audit by the Civil Aviation Safety Authority. Failure to comply with the directives outlined in the Civil Aviation Regulations 1998 can result in severe penalties and consequences. Operators found to be in breach of the airworthiness directives may face enforcement actions, including fines and potential suspension or revocation of the aircraft’s certificate of airworthiness. In cases of non-compliance, the maximum penalties can be significant, reflecting the gravity of ensuring aviation safety. Additionally, any incidents or accidents arising from failure to adhere to these regulations could lead to criminal charges, further underscoring the importance of strict compliance (section 39-105).
