Overview
The Civil Aviation Regulations 1998, enacted by the Australian Government, were established to regulate the safety standards within the civil aviation industry. These regulations aim to ensure the safety of all civil aviation operations within Australia, aligning with international standards and practices. Specifically, Part 39 - 105 within the Civil Aviation Regulations 1998 outlines the Airworthiness Directives which mandate the maintenance and safety checks required for various aircraft models. One such directive, AD/TB20/1, pertains to Aerospatiale (Socata) TB20 (Trinidad) Series Aeroplanes, focusing on the inspection and potential replacement of engine mounts to address issues arising from the use of incorrect specification steel in their manufacture. Compliance with these directives is crucial to maintaining the airworthiness of affected aircraft and ensuring the safety of passengers and crew.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, encompasses the Civil Aviation Safety Authority's schedule of airworthiness directives, which apply to various aircraft models and their parts. In this particular instance, the regulation targets Aerospatiale (Socata) TB20 (Trinidad) series aeroplanes with specific serial numbers. This directive mandates an inspection and potential replacement of the engine mount P/No. TB20.51.000.001 for certain serial numbers and requires the installation of a new engine mount made of 15CDV6 steel, provided it does not bear one of the specified serial numbers. This directive applies to aircraft owners, operators, and maintenance personnel who must comply before further flight. The regulation's geographic reach is national, applying uniformly across Australia, as it is a Commonwealth regulation. The directive does not specify any exclusions or exemptions, but compliance is mandatory for the affected aircraft.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105 (section 39.105) mandates the inspection and, if necessary, replacement of engine mounts for certain Aerospatiale (Socata) TB20 (Trinidad) series aeroplanes. This requirement is outlined in AD/TB20/1, which applies to model TB20 aeroplanes with specific serial numbers (339, 355, 358, 360, 379, 380, 384, 385, and 386). The regulation mandates an inspection of engine mount P/No. TB20.51.000.001 for certain serial numbers (37, 38, 39, 40, 47, 43, 51, 50, and 45). If any of these engine mounts are found, they must be replaced and installed with a new engine mount P/No. TB20.51.000.001 made of 15CDV6 steel that does not bear one of the specified serial numbers. Compliance with these directives is mandatory before any further flight.
The Civil Aviation Regulations 1998 impose specific obligations on the operators and maintainers of the affected aircraft. Operators must ensure that the engine mounts of the specified model and serial numbers are inspected as per the directive. If any of the engine mounts identified by the serial numbers specified in the directive are found, they must be replaced immediately with a new engine mount made of the correct steel. Additionally, operators must ensure that all replacement parts meet the specifications provided and are compliant with Aerospatiale SB No. 20 GR 71-09. Failure to comply with these requirements before further flight can result in significant safety risks and potential regulatory consequences.
Failure to comply with the requirements outlined in AD/TB20/1 can result in serious consequences. According to section 39.105 of the Civil Aviation Regulations 1998, non-compliance with Airworthiness Directives can lead to various penalties. The exact nature of the penalties may vary, but they could include fines, suspension of the aircraft's airworthiness certificate, or even criminal charges in severe cases. The maximum penalties for breaches of these regulations can include substantial fines, imprisonment, or both, depending on the severity and circumstances of the non-compliance. It is crucial for operators and maintainers to adhere strictly to these directives to avoid such severe repercussions.
