AD/AUS/5 Amdt 1 - Landing Gear

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, were designed to address the need for comprehensive safety measures within the civil aviation sector. Specifically, Part 39 - 105 of these regulations focuses on the issuance of airworthiness directives to ensure the safety and airworthiness of aircraft. The amendments introduced under AD/AUS/5 aim to rectify potential safety issues related to the landing gear of Auster/Beagle A.61 Series Aeroplanes manufactured before October 1947. The policy objective behind these amendments is to mitigate risks associated with structural integrity by mandating regular inspections and necessary repairs of the landing gear components. Compliance with these directives is overseen by the Civil Aviation Safety Authority, ensuring that the aircraft maintain their airworthiness throughout their operational life.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 and the Airworthiness Directive AD/AUS/5 Amendment 1, applies to all Auster/Beagle A.61 Series aeroplanes manufactured before October 1947. This legislation sets out mandatory safety requirements and inspections for the landing gear of these aircraft. The directive applies to any person or entity responsible for the maintenance and operation of these aircraft, ensuring adherence to stringent safety standards to maintain airworthiness. The regulations extend to the entire Commonwealth of Australia, ensuring a uniform approach to aviation safety across the nation. There are no stated exclusions or exemptions in this directive, meaning that all qualifying aircraft must comply with the specified inspection and maintenance requirements. The regulations can be further detailed and extended through subordinate instruments, which may provide additional technical specifications and enforcement guidelines.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Section 105, addresses the airworthiness directives for Auster/Beagle A.61 Series Aeroplanes in Amendment 1, which pertains to the landing gear (AD/AUS/5Amdt 1). This directive applies to all models of these aeroplanes manufactured before October 1947. Section 1 of the directive mandates several inspection and maintenance tasks to ensure the safety of the landing gear system. These tasks include inspecting the welding at the top of the radius rods near the shock cord spools for any cracks or damage, examining the lower ends of the radius rods and the radius rod attachment bolts for damage, and turning the bolts with a spanner to check for tightness and inspect for any damage or distortion if they are excessively tight. Furthermore, the directive requires the removal of landing wheels to inspect the welds at the stub axle roots for cracks. Any defective components identified during these inspections must be replaced or repaired according to a repair scheme approved by the Secretary. The obligations imposed by the Civil Aviation Regulations 1998 on the parties governed by this directive are stringent and clear. Operators and owners of Auster/Beagle A.61 Series Aeroplanes must conduct the specified inspections and maintenance at intervals not exceeding 500 hours of time in service and after each heavy landing. Additionally, all inspections must be carried out with the aid of a hand lens with a magnification of at least 10X to ensure that any minute damage or defects are identified. Compliance with these requirements is critical to maintaining the airworthiness of the aircraft and ensuring the safety of all passengers and crew. Failure to comply with the provisions of the Civil Aviation Regulations 1998 can result in significant legal consequences. While the specific penalties are not detailed in the directive, breaches of civil aviation regulations can typically result in fines, enforcement actions, and potentially the grounding of the aircraft. For operators, non-compliance can lead to reputational damage and increased scrutiny from regulatory authorities, which may further impact their operations and financial standing. Ensuring adherence to these airworthiness directives is therefore not only a regulatory requirement but also a fundamental aspect of maintaining safe and reliable aviation operations.
