AD/GAF-N22/7 - Engine Oil Tank Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, aim to ensure the safety and efficiency of civil aviation operations within Australia. Among these regulations is the Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, which addresses specific safety concerns pertaining to aircraft models and their components. One such directive is AD/GAF-N22/7, which pertains to the replacement of the engine oil tank for GAF N22 and N24 Series Aeroplanes. This directive was introduced to address the problem of engine oil tank failures that could potentially compromise the safety of the aircraft. The policy objective behind this regulation is to ensure that aircraft remain airworthy and compliant with safety standards by mandating timely maintenance and replacement of critical components like the engine oil tank. The specific directive AD/GAF-N22/7 applies to the GAF N22 model aeroplanes with serial numbers N22-1, N22-2, and N22-4. It requires compliance within 100 hours of time in service following 28 November 1975. The directive references GAF Service Bulletin No. N22.79.2 for further details on the compliance requirements. By setting such mandates, the Civil Aviation Safety Authority seeks to mitigate risks associated with ageing or defective aircraft parts, thereby enhancing overall aviation safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the application of airworthiness directives, including AD/GAF-N22/7 concerning the engine oil tank replacement for GAF N22 and N24 series aeroplanes. This legislative instrument applies to specific models of aeroplanes, namely those within the GAF N22 series with serial numbers N22-1, N22-2, and N22-4. Compliance with this directive is mandatory for these aircraft, requiring the replacement of the engine oil tank within 100 hours of time in service after 28 November 1975. The regulation extends across the Commonwealth of Australia, enforcing safety standards that are essential for the operation of these specific aircraft types. Subordinate instruments may further define the technical requirements and compliance procedures, ensuring that the airworthiness directives are effectively implemented within the aviation industry.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, specifically mandate compliance with Airworthiness Directives (ADs) for certain aircraft models. In this context, AD/GAF-N22/7 pertains to the engine oil tank replacement for GAF N22 and N24 series aeroplanes, particularly those with serial numbers N22-1, N22-2, and N22-4. The directive requires compliance within 100 hours of time in service following 28 November 1975 (Section 39 - 105). To ensure compliance, operators must refer to GAF Service Bulletin No. N22.79.2, which details the necessary procedures and specifications for the engine oil tank replacement. Operators of the affected GAF N22 series aeroplanes are obligated to follow the outlined procedures in GAF Service Bulletin No. N22.79.2 to ensure the engine oil tank is replaced within the specified timeframe. This includes conducting the necessary inspections, replacements, and maintenance as detailed in the bulletin. Failure to comply with these requirements can result in the aircraft being deemed non-airworthy, which could prevent it from being operated legally. Violations of the Civil Aviation Regulations 1998, particularly non-compliance with ADs such as AD/GAF-N22/7, can lead to significant consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce these regulations. For breaches, there can be both civil and criminal penalties. Civil penalties can include fines, while criminal penalties can result in imprisonment. The exact penalties are not specified in the legislation but can vary based on the severity and impact of the non-compliance. The enforcement actions taken by CASA are intended to ensure the safety and reliability of civil aviation operations.
