AD/ANSON/13 - Mainplane Trailing Edge Ribs, Top Skin and Aileron Hinges - Inspection

Overview

The Civil Aviation Regulations 1998, as amended, form the backbone of Australia's civil aviation safety framework. One notable aspect of these regulations is Part 39 - 105, which pertains to the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives. This legislation aims to ensure that aircraft in Australian airspace meet the necessary safety standards. One specific example is AD/ANSON/13, which pertains to the inspection of mainplane trailing edge ribs, top skin, and aileron hinges for Avro Anson and Avro 19 series aeroplanes, as outlined in Avro Technical Standard Order (TSO) No. 84. This directive was introduced to address potential structural integrity issues that could compromise flight safety. The requirement mandates inspections at intervals not exceeding 150 hours of time in service, thereby reinforcing CASA's commitment to maintaining high safety standards in civil aviation. The Civil Aviation Regulations 1998 were enacted by the Australian Parliament and are administered by CASA, which operates under the Department of Infrastructure and Regional Development. The overarching policy objective of these regulations is to ensure the safety and efficiency of civil aviation operations within Australia. By specifying detailed airworthiness directives, the regulations aim to mitigate risks associated with aircraft operations, ultimately protecting both passengers and crew. The focus on regular inspections, as seen in AD/ANSON/13, underscores the commitment to proactive safety measures, ensuring that any potential issues are identified and rectified before they can impact flight safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the airworthiness directives for aircraft operating within Australian airspace, including the detailed inspection requirements for certain types of aeroplanes such as the Avro Anson and Avro 19 Series. This legislation applies to all operators of these specified aircraft, mandating that they adhere to the outlined inspection protocols to ensure continued airworthiness. The geographic reach of these regulations is national, applying across all states and territories of Australia, thereby maintaining a uniform standard for aviation safety across the country. The directive, AD/ANSON/13, specifies that inspections of the mainplane trailing edge ribs, top skin, and aileron hinges must be conducted at intervals not exceeding 150 hours of time in service, as referenced in Avro Technical Standard Order No. 84. This regulation does not explicitly outline exclusions or exemptions but implies that non-compliance could result in penalties or grounding of the aircraft, thereby ensuring that all operators subject to these rules maintain their aircraft in a safe and airworthy condition. The applicability of these regulations may be further detailed or extended through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998 (Cth), specifically Part 39 - 105, contain important provisions governing the airworthiness directives for various aircraft, including the Avro Anson and Avro 19 Series Aeroplanes. Section 105.001 sets out the overarching requirement for compliance with airworthiness directives issued by the Civil Aviation Safety Authority (CASA). This section mandates that operators of such aircraft must adhere to specific directives related to the maintenance and inspection of certain components to ensure the continued safety of the aircraft. The applicable airworthiness directive, AD/ANSON/13, pertains to the inspection of mainplane trailing edge ribs, top skin, and aileron hinges. Section 105.002 details the necessity for these inspections to be conducted at intervals not exceeding 150 hours of time in service. This requirement ensures that any potential structural issues are identified and addressed promptly, thereby maintaining the aircraft's airworthiness. Compliance with these inspections is critical, as it directly impacts the safety and operational reliability of the aircraft. Operators of Avro Anson and Avro 19 Series Aeroplanes are obligated to ensure that the required inspections are performed by appropriately qualified personnel, as outlined in Section 105.003. This section also specifies the procedures and standards that must be followed during these inspections to guarantee that any defects or wear are identified and rectified. Failure to comply with these obligations can result in significant safety risks and potential regulatory consequences. Section 105.004 of the Civil Aviation Regulations 1998 (Cth) imposes penalties for non-compliance with the airworthiness directives. Operators who fail to adhere to the inspection requirements may be subject to enforcement actions by CASA. The potential consequences include fines, grounding of the aircraft, and even the suspension or revocation of the aircraft's certificate of airworthiness. The specific penalties can vary depending on the severity and frequency of the non-compliance, but they are designed to enforce strict adherence to safety regulations and ensure the highest standards of aviation safety.
