AD/G159/35 - Fuselage Top Escape Hatch Structure - Inspection

Overview

The Civil Aviation Orders, enacted in 1988, serve to regulate aviation safety across Australia, with the overarching aim of ensuring the highest safety standards in the operation of aircraft. One specific aspect of this comprehensive regulatory framework is the issuance of Airworthiness Directives, which are legally binding instructions issued by the Civil Aviation Safety Authority (CASA) to address identified safety deficiencies or risks. These directives are designed to ensure that aircraft remain in a safe condition for operation and are consistent with maintaining public confidence in the safety of the aviation industry. The policy objective behind these directives is to proactively manage and mitigate potential safety risks by requiring specific actions or inspections on aircraft, thereby preventing accidents and ensuring the safety of passengers and crew. The Civil Aviation Orders were enacted by the Parliament of Australia and are administered by CASA, which is responsible for enforcing the regulations and issuing directives as necessary to address any identified safety issues. For instance, AD/G159/35, issued under the Civil Aviation Orders, pertains to the inspection of the fuselage top escape hatch structure on Gulfstream (Grumman) G.159 series aeroplanes. This directive was introduced to address a specific safety concern related to the structural integrity of the escape hatch, ensuring that all G159 models comply with the specified inspection requirements to maintain airworthiness.

Scope and Application

The Civil Aviation Orders, as encapsulated in the legislative instrument F2006B10079, specifically pertain to the operations and safety standards of civil aviation in Australia. This particular regulation, found in Part 105 Schedule of Airworthiness Directives, mandates the inspection of the fuselage top escape hatch structure for all models of the Gulfstream (Grumman) G159 series aeroplanes, as detailed in AD/G159/35 dated 1/79. The directive applies universally to all G159 models operating within Australian airspace and mandates compliance with the specified requirements as outlined in Grumman American Customer Bulletin No. 305. The directive is enforced by the Civil Aviation Safety Authority, which is the federal government body responsible for the regulation and safety oversight of civil aviation in Australia. While the Act itself does not specify exclusions or exemptions, compliance with subordinate instruments or further clarifications may extend or restrict its application.

Key Provisions

The primary operative sections of the Civil Aviation Orders, specifically AD/G159/35, mandate that all models of the Gulfstream (Grumman) G.159 series aeroplanes must undergo a detailed inspection of the fuselage top escape hatch structure. Section 1 of the Order identifies the applicability of the directive to all G159 models and references Grumman American Customer Bulletin No. 305 as the document detailing the compliance requirements. These requirements include specific inspection procedures and criteria that must be met to ensure the structural integrity of the escape hatch, which is crucial for passenger safety in emergency situations. The Act imposes several obligations on the operators and owners of the Gulfstream (Grumman) G.159 series aeroplanes. Primarily, these include conducting the mandated inspections in accordance with the detailed procedures outlined in Grumman American Customer Bulletin No. 305. Operators must ensure that qualified personnel perform these inspections, and if any defects or issues are identified, they must be rectified before the aeroplane is returned to service. Additionally, operators are required to maintain records of all inspections and any corrective actions taken, ensuring traceability and accountability for compliance with the directive. Failure to comply with the provisions of AD/G159/35 can result in significant legal consequences. Under the Civil Aviation Act 1988, non-compliance with Airworthiness Directives is a strict liability offence, which means that the burden of proof does not lie with the prosecution. Operators found in breach of this directive may face substantial fines and potential criminal charges, which can include imprisonment. The specific penalties can vary, but the Act provides for fines that can reach up to several thousand dollars, depending on the severity and circumstances of the non-compliance. Moreover, persistent or egregious breaches could lead to further regulatory actions, including the suspension or revocation of the aeroplane’s certificate of airworthiness, which would ground the aircraft until all issues are rectified.
