AD/G1159/17 - Stall Barrier System In-Line Filters - Replacement

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority, are essential in ensuring the safety of civil aviation in Australia. One of the legislative instruments under this act is the AD/G1159/17 which pertains to the Gulfstream (Grumman) G1159 and G-IV series aeroplanes. This regulation was enacted to address specific safety concerns associated with the stall barrier system in-line filters of these aircraft models. The policy objective, as stated in the text, is to ensure compliance with the Grumman Aircraft Service Change No. 199, which mandates the replacement of these filters to mitigate potential safety risks. This regulatory measure is integral to maintaining the operational safety of the specified aircraft models, ensuring that they meet the stringent safety standards set forth by Australian civil aviation authorities.

Scope and Application

The Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive (AD) under the Civil Aviation Regulations 1998, which applies specifically to Gulfstream (Grumman) G1159 and G-IV series aeroplanes, particularly those with serial numbers (S/Nos.) 1 to 164 and 775. This regulation mandates the replacement of in-line filters within the stall barrier system as stipulated in Grumman Aircraft Service Change No. 199. The directive is applicable to the specified aircraft models, ensuring compliance with the outlined requirements for continued airworthiness. The directive is a Commonwealth regulation, thereby holding jurisdictional reach across Australia, enforcing safety standards that must be met by operators of the specified aircraft. There are no exclusions, exemptions, or thresholds specified within this particular AD, meaning that all affected aircraft must adhere to the mandated changes without exception. Subordinate instruments may extend or further clarify the application of this directive, but the primary directive itself remains clear in its scope and requirements.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105 and the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, detail the requirements for the Gulfstream (Grumman) G1159 and G-IV Series Aeroplanes concerning the stall barrier system in-line filters. The key provision in this regard is found in AD/G1159/17 (Section 8/75), which mandates the replacement of the stall barrier system in-line filters for specific models. This directive applies to model G1159 with serial numbers ranging from 1 to 164 and 775 (Section 8/75). Under this legislation, the primary obligation imposed on the parties or entities it governs is to ensure compliance with the specified requirements as detailed in Grumman Aircraft Service Change No. 199. This entails the necessary replacement of the stall barrier system in-line filters in accordance with the document's stipulations to maintain the airworthiness and safety of the aircraft in question. Failure to comply with the provisions of AD/G1159/17 can result in significant consequences. The legislation does not explicitly state specific penalties or consequences for non-compliance, but non-compliance with airworthiness directives generally can lead to severe repercussions. These may include civil penalties, criminal charges, and potential grounding of the aircraft, thereby affecting both the operational viability and safety of the flights. The seriousness of these outcomes underscores the importance of adhering to the directive to ensure the continued safety and airworthiness of the aircraft.
