AD/G159/34 - Outer Wing to Integral Tank Front and Rear Beam Splices - Inspection

Overview

The Civil Aviation Orders were enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of the industry. Specifically, the Civil Aviation (Airworthiness) Order 1991, administered by the Civil Aviation Safety Authority (CASA), establishes the standards and procedures for maintaining aircraft airworthiness. One of the key components of this legislative framework is the issuance of Airworthiness Directives (ADs), which are legally enforceable orders that require corrective action to address safety issues identified in specific aircraft types. AD/G159/34, pertaining to the Gulf Stream (Grumman) G.159 series aeroplanes, is an example of such directives, mandating inspections of the outer wing to integral tank front and rear beam splices to ensure continued airworthiness and safety. This legislative instrument was introduced to address gaps in aircraft maintenance and safety protocols, aiming to mitigate risks associated with structural integrity and ensure compliance with safety standards as outlined in the relevant customer bulletins and compliance documents.

Scope and Application

The Civil Aviation Orders, specifically Part 105 Schedule of Airworthiness Directives, applies to all models of the Gulfstream (Grumman) G.159 series aeroplanes, mandating compliance with the stipulated airworthiness directives. These directives are designed to ensure the safe operation of these aircraft and encompass inspections, maintenance, and repair activities as outlined in the specific AD/G159/34, which addresses the outer wing to integral tank front and rear beam splices. The legislation extends to all persons and entities involved in the maintenance, operation, or ownership of these aircraft, ensuring adherence to safety standards set forth by the Civil Aviation Safety Authority (CASA). The scope of the Act is national, applying across the Commonwealth of Australia, and it is enforced through subordinate instruments that may further detail compliance requirements and penalties for non-compliance. Any exclusions or exemptions from these requirements must be clearly stated in the subordinate instruments or specific directives, ensuring that all stakeholders are aware of their obligations under the legislation.

Key Provisions

The Civil Aviation Orders, specifically Part 105, establish the Schedule of Airworthiness Directives, which includes detailed instructions for maintaining the safety and airworthiness of aircraft. In this context, AD/G159/34 pertains to the inspection of the outer wing to integral tank front and rear beam splices of the Gulfstream (Grumman) G.159 series aeroplanes. Section 1/79 outlines that this directive applies to all models G159, ensuring uniformity in safety measures across the fleet. The compliance requirement is to follow the stipulations in Grumman American Customer Bulletin No. 296, which provides specific guidance on how these inspections should be conducted. Entities and individuals governed by these directives must adhere to the outlined procedures to maintain compliance. This includes performing inspections as specified in the Customer Bulletin, ensuring that the outer wing to integral tank front and rear beam splices are in the required condition to avoid any potential safety risks. Failure to comply with these directives can lead to significant operational and legal repercussions, as the directives are integral to maintaining the safety standards set forth by the Civil Aviation Safety Authority. Breach of these airworthiness directives can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can lead to criminal charges, with potential penalties including substantial fines and imprisonment. Specifically, Section 30 of the Act provides for a maximum penalty of up to $21,600 for individuals and $108,000 for corporations if found guilty of contravening an airworthiness directive. Additionally, the safety authority may take civil action, which could result in further financial penalties or the grounding of the aircraft until the required inspections are satisfactorily completed. These stringent measures underscore the importance of adhering to the directives to ensure the continued safety and airworthiness of the aircraft.
