Overview
The Civil Aviation Orders, established under the Civil Aviation Act 1988, aim to ensure the safety and efficiency of civil aviation in Australia. The particular legislative instrument F2006B10057, issued by the Civil Aviation Safety Authority, addresses specific airworthiness concerns for the Gulfstream (Grumman) G.159 series aeroplanes. This directive, effective from 11 September 1997, focuses on the prevention of elevator trim tab mounting lug failures due to cracking, ensuring the continued safety and airworthiness of these aircraft. The requirement outlined in Amendment 3 mandates specific actions and installations to mitigate these risks, aligning with both Australian and international safety standards.
The policy objective of this legislative instrument is to maintain and enhance the safety of civil aviation by addressing specific technical issues that could potentially compromise the integrity of the aircraft. By enforcing regular inspections and necessary modifications, the directive ensures that the aircraft remain compliant with safety regulations, thus protecting the interests of passengers, crew, and the broader aviation community.
Scope and Application
The F2006B10057 (Legislative instrument) Civil Aviation Orders, specifically Part 105 Schedule of Airworthiness Directives for Gulfstream (Grumman) G.159 series aeroplanes, applies to all models of the Gulfstream (Grumman) G.159 series aeroplanes that are not fitted with trim tab actuators Part Number 159SCC100-11. The directive is issued under the authority of the Civil Aviation Safety Authority (CASA) and pertains to the Commonwealth of Australia, thereby having a national reach. The purpose of this directive is to ensure the airworthiness and safety of the aircraft by addressing the potential failure of the elevator trim tab mounting lugs due to cracking. The directive mandates specific actions to be taken in accordance with Gulfstream (Grumman) Customer Bulletin 208A, as amended by Amendments 1 and 2, and the installation of the specified trim tab actuator in compliance with Gulfstream Aircraft Service Change 191. Compliance is required within specific timeframes post the last inspection or by a specified date, and thereafter at intervals not exceeding 200 hours of time in service. This airworthiness directive became effective on 11 September 1997 and provides terminating action for the inspection as per Amendment 3.
Key Provisions
The Civil Aviation Orders, specifically Part 105 Schedule of Airworthiness Directives, contain provisions that govern the maintenance and safety of aircraft, with AD/G159/13 Amendment 3 focusing on the Gulfstream (Grumman) G.159 series aeroplanes. Section 1 of the directive mandates that action must be taken in accordance with Gulfstream (Grumman) Customer Bulletin 208A, as amended by Amendments 1 and 2. Furthermore, it requires the installation of a specific trim tab actuator, Part Number 159SCC100-11, following Gulfstream Aircraft Service Change 191. This directive references FAA AD 97-14-09 for additional context and guidance.
Compliance with the AD/G159/13 Amendment 3 is critical for the continued safe operation of the Gulfstream (Grumman) G.159 series aeroplanes. Operators must ensure that the required actions are carried out within 200 hours of time in service following the last inspection according to the previous version of this directive, or before 30 September 1997, whichever is later. Additionally, operators must adhere to these requirements every 200 hours of time in service thereafter. For aeroplanes that have accumulated 1000 hours of time in service after 11 September 1997, the compliance action must be taken within that timeframe.
The AD/G159/13 Amendment 3 sets out specific obligations for the operators of Gulfstream (Grumman) G.159 series aeroplanes. These include conducting inspections and maintenance actions as stipulated in Gulfstream (Grumman) Customer Bulletin 208A and installing the specified trim tab actuator in line with Gulfstream Aircraft Service Change 191. These obligations are designed to prevent the failure of elevator trim tab mounting lugs, which could occur due to cracking, thereby ensuring the continued airworthiness of the aircraft.
Failure to comply with the provisions of AD/G159/13 Amendment 3 may result in serious safety implications. While the specific legal consequences are not detailed in the text, non-compliance with airworthiness directives generally carries significant civil and potentially criminal penalties under Australian aviation law. Operators who do not adhere to these requirements may face enforcement actions, including fines and potential grounding of the aircraft until the necessary actions are taken.
