Overview

The Civil Aviation Orders were enacted by the Australian Government to ensure the safety and regulation of civil aviation within the country. The F2006B10084 legislative instrument, specifically the Airworthiness Directive AD/G159/40 concerning Gulfstream (Grumman) G.159 series aeroplanes, was introduced to address a critical safety issue identified with the main and nose landing gear uplock cylinder attach bolts. This directive aims to mitigate the risk of gear-up landings, which can be catastrophic, by mandating the replacement of these bolts. The policy objective is to enhance aviation safety by ensuring that all applicable aircraft are compliant with the specified maintenance requirements. The directive applies to all models G159-1, -1C, and -TC4C and requires compliance within 100 hours of time in service after 31 May 1982, following the incident involving an overseas aeroplane that led to the loss of a main landing gear uplock cylinder attach bolt.

Scope and Application

The Civil Aviation Orders, specifically Part 105 Schedule of Airworthiness Directives, address the safety and compliance of various aircraft types, including the Gulfstream (Grumman) G.159 series aeroplanes. The particular Airworthiness Directive AD/G159/40 pertains to the replacement of the main and nose landing gear uplock cylinder attach bolts for all models G159-1, -1C, and -TC4C. This directive applies to any entity or person operating these specified models within Australia, ensuring adherence to stringent safety standards set forth by the Civil Aviation Safety Authority. The directive is designed to mitigate the risk of a gear-up landing, a serious safety hazard, by mandating that the replacement of the attach bolts must be completed within 100 hours of time in service after 31 May 1982, following the issuance of Gulfstream American Customer Bulletin No. 285A.5/82. This requirement underscores the importance of maintaining critical components of the aircraft to prevent accidents stemming from mechanical failures.

Key Provisions

The Civil Aviation Orders, specifically under Part 105 Schedule of Airworthiness Directives, outlines provisions for ensuring the safety of aircraft through Airworthiness Directives (ADs). One such directive, AD/G159/40, pertains to the Gulfstream (Grumman) G.159 series aeroplanes and mandates the replacement of main and nose landing gear uplock cylinder attach bolts. This directive applies to all models G159-1, -1C, and -TC4C (section 1). The directive references Gulfstream American Customer Bulletin No. 285A.5/82 as the document providing the necessary details for compliance (section 2). The compliance requirement is that these replacements must be completed within 100 hours of time in service after 31 May 1982, unless already accomplished (section 3). Under this legislation, the parties and entities governed, primarily the aircraft operators and maintenance personnel, are required to adhere to the specified maintenance and replacement protocols. This includes ensuring that all models of the Gulfstream G.159 series aeroplanes have their main and nose landing gear uplock cylinder attach bolts replaced within the stipulated timeframe. Failure to comply with these directives may result in the aircraft being deemed non-airworthy, which could lead to grounding of the aeroplane until the necessary maintenance is performed. The Civil Aviation Orders impose significant obligations on the entities it governs. They must ensure strict adherence to the maintenance schedules and requirements outlined in the ADs to maintain airworthiness. Specifically, for AD/G159/40, the operators and maintenance personnel must ensure the replacement of the specified bolts within the given timeframe to prevent potential safety hazards. Non-compliance with these requirements can have severe consequences, including the potential for a safety incident involving the aircraft. In terms of consequences for breach, the Civil Aviation Orders do not explicitly outline the penalties within the text provided. However, generally, under Australian aviation law, non-compliance with airworthiness directives can lead to severe penalties. These may include fines, suspension or revocation of the operator's licence, and potential criminal charges if the breach results in harm or damage. The maximum penalties can vary based on the severity of the breach and the impact on aviation safety. It is essential for all governed entities to understand and comply with these directives to avoid such repercussions.
