AD/G164/12 - Fuel Quantity Indicator Presentation - Inspection

Overview

The Civil Aviation Regulations 1998, amended by the Legislative Instrument F2006B10097, introduces specific airworthiness directives for Schweizer (Grumman) G-164 (Ag-Cat) Series Aeroplanes, aiming to ensure the safety and reliability of these aircraft. Enacted by the Australian Parliament, this legislation addresses the need for stringent oversight and maintenance requirements for certain aircraft models to mitigate the risks associated with aging aviation technology and ensure compliance with evolving safety standards. The policy objective of this directive is to mandate inspections and compliance measures within a specified timeframe, enhancing the overall safety of civil aviation operations and protecting both passengers and crew. This legislative instrument, issued under the authority of the Civil Aviation Act 1988, provides clear instructions for the inspection and maintenance of the fuel quantity indicator on Schweizer (Grumman) G-164 (Ag-Cat) Series Aeroplanes. The directive stipulates that all models must undergo an inspection within 100 hours of time in service following 30 June 1972, as outlined in Grumman G164 Service Bulletin No. 48. By enforcing these requirements, the legislation seeks to address potential safety issues related to the accuracy and functionality of the fuel quantity indicator, thereby contributing to the overarching goal of maintaining high safety standards in Australian civil aviation.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically AD/G164/12, pertains to all models of Schweizer (Grumman) G-164 (Ag-Cat) series aeroplanes. This directive mandates that a specific inspection of the fuel quantity indicator presentation be carried out in accordance with Grumman G164 Service Bulletin No. 48. The directive applies to any entity operating these aircraft models, requiring compliance within 100 hours of time in service after 30 June 1972. This regulation is under the purview of the Commonwealth of Australia and is part of the Civil Aviation Regulations 1998, reflecting the national jurisdictional reach of this safety directive. The directive does not specify any exclusions or exemptions, and compliance is mandatory for the safety and airworthiness of the specified aircraft. Subordinate instruments may further detail the implementation and compliance requirements, but the primary scope and applicability are clearly defined within the regulation itself.

Key Provisions

The Civil Aviation Regulations 1998 (Cth), specifically Part 39, Section 105, include an airworthiness directive for Schweizer (Grumman) G-164 (Ag-Cat) Series Aeroplanes. The directive, AD/G164/12, pertains to the inspection of the fuel quantity indicator presentation and applies to all models within this series (s. 105). The compliance requirement is for inspections to be carried out within 100 hours of time in service after 30 June 1972, as detailed in Grumman G164 Service Bulletin No. 48 (s. 105). This directive aims to ensure that the fuel quantity indicators on these aircraft are presented correctly, which is critical for flight safety and operational efficiency. Under this legislation, the parties or entities governed by the directive, such as aircraft owners, operators, and maintenance personnel, have specific obligations. They are required to perform the mandated inspection of the fuel quantity indicator presentation in accordance with the stipulated timeframe and documentation provided by Grumman G164 Service Bulletin No. 48 (s. 105). The regulations require that the inspection be conducted thoroughly to verify that the indicators are functioning correctly and presenting accurate fuel levels. Ensuring compliance involves meticulous record-keeping and adherence to the manufacturer’s guidelines to maintain the aircraft’s airworthiness status. Failure to comply with the airworthiness directive can result in serious consequences. Non-compliance with the inspection requirements could lead to the aircraft being deemed unairworthy, which may result in grounding and potential legal action. The regulations do not explicitly state the maximum penalties for non-compliance in this specific context, but non-compliance with civil aviation regulations generally can lead to substantial fines and legal penalties. Additionally, operators found to be in breach may face enforcement actions by the Civil Aviation Safety Authority, including the imposition of compliance orders or further inspections. Such breaches can also have significant implications for flight safety, potentially leading to civil or criminal liability if an incident occurs due to the non-functioning fuel quantity indicators.
