AD/G1159/1 - Airspeed Limitation Placard - Rework

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, were established to ensure the safety and regulation of civil aviation within the country. Among the many parts, Part 39 - 105 specifically pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, addressing various aircraft safety concerns. This legislation is instrumental in maintaining stringent safety standards and ensuring that aircraft meet necessary operational requirements. One such directive is AD/G1159/1, which concerns the Gulf Stream (Grumman) G1159 and G-IV series aeroplanes, focusing on the airspeed limitation placard rework. The directive applies to all models with specific serial numbers and requires compliance within a stipulated time frame post a designated date, as outlined in Grumman Gulfstream II Service Change No. 99. The overarching policy objective is to enhance aircraft safety through precise regulatory oversight and timely compliance actions.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives under the Civil Aviation Regulations 1998 applies specifically to Gulfstream (Grumman) G1159 and G-IV series aeroplanes, more precisely to those with serial numbers ranging from 1 to 101 and 775. This directive mandates rework of the airspeed limitation placard as detailed in Grumman Gulfstream II Service Change No. 99. The directive requires compliance within 50 hours of time in service following 27 July 1971. This regulation is applicable to all relevant aircraft models within the specified serial number range, ensuring that any operator or owner of such aircraft adheres to the stipulated safety modifications. The jurisdictional reach of this directive is national, governed by the Commonwealth of Australia, and administered by the Civil Aviation Safety Authority, with no noted exclusions or exemptions for the specified models and serial numbers. The application of this directive may be further extended or specified through subordinate instruments, which may provide additional details or clarify compliance requirements.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, include a schedule of airworthiness directives that pertain to various aircraft types. In this case, the regulations address Gulfstream (Grumman) G1159 and G-IV series aeroplanes, with a focus on airspeed limitation placard rework as outlined in AD/G1159/1 (Section 39-105). This directive applies to all models with specific serial numbers (S/Nos. 1 to 101 and 775) and requires compliance with the Grumman Gulfstream II Service Change No. 99 (Section 39-105). The compliance must be achieved within 50 hours of time in service after 27 July 1971. The obligations imposed by this directive are clear and specific. Operators of the affected aircraft must ensure that the airspeed limitation placard rework, as detailed in Grumman Gulfstream II Service Change No. 99, is completed within the stipulated timeframe (Section 39-105). This involves making necessary modifications to the airspeed limitation placards to ensure they meet the current safety standards. Operators must maintain records of compliance and ensure that all relevant personnel are informed about the changes and their implications. Failure to comply with the airworthiness directive can result in serious consequences. The regulations do not explicitly state the penalties for non-compliance in this particular directive; however, non-compliance with airworthiness directives generally can lead to severe penalties under the Civil Aviation Act 1988 (Section 60-105). These penalties can include fines, imprisonment, or both, depending on the severity of the breach and the potential risk posed to aviation safety. Operators found in breach of these directives may also face additional administrative actions, such as the grounding of affected aircraft until compliance is achieved.
