AD/AC-112/4 - Engine Oil Pressure Line - Replacement

Overview

The Civil Aviation Regulations 1998 (Cth) were enacted by the Australian Parliament to establish a comprehensive regulatory framework governing civil aviation in Australia. The aim was to ensure the safety and efficiency of the national airspace system, alongside the protection of the public from the risks associated with aviation activities. One aspect of these regulations, captured in Part 39 - 105, addresses Airworthiness Directives for specific aircraft models, such as the Gulfstream (Rockwell) 112 Series Aeroplanes, ensuring ongoing compliance with safety standards. The policy objective behind these regulations is to mandate the maintenance and operational standards that minimise aviation risks, thereby fostering a safe and reliable civil aviation environment.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, mandates the compliance of Gulfstream (Rockwell) 112 Series aeroplanes concerning an airworthiness directive regarding engine oil pressure line replacement. This legislation applies to aircraft model 112 with serial numbers ranging from 3 to 470. The directive mandates that compliance must be achieved within 100 hours of time in service following 31 January 1977. This regulation is intended to ensure that the specified aircraft maintain the required safety standards, and as such, it encompasses all entities operating these models within the Australian jurisdiction. The directive is supported by Rockwell International Service Bulletin No. SB-112-46, Part II, which provides detailed instructions for compliance. This legislative instrument ensures that the specified aircraft meet stringent safety requirements, thereby protecting both the operators and the passengers.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998 (Part 39 - 105) concerning the Gulf Stream (Rockwell) 112 Series Aeroplanes focus on the engine oil pressure line replacement. Section 105 specifically mandates the replacement of the engine oil pressure line for the Model 112 with serial numbers 3 to 470. This directive is applicable within 100 hours of time in service after 31 January 1977, as outlined in Rockwell International Service Bulletin No. SB-112-46, Part II. This requirement ensures that the aircraft maintain adequate oil pressure, preventing engine failure and enhancing safety during flight. The Civil Aviation Regulations 1998 impose several obligations on the parties involved. Firstly, aircraft operators must comply with the airworthiness directive by ensuring that the specified engine oil pressure line replacement is carried out within the stipulated timeframe. This involves meticulous record-keeping of the aircraft’s flight hours and adherence to the compliance schedule. Operators must also ensure that the replacement is performed by qualified personnel who follow the guidelines set out in the Rockwell International Service Bulletin. These measures are critical to maintaining the aircraft's airworthiness and ensuring the safety of all passengers and crew. Non-compliance with the airworthiness directive can result in severe consequences. Under Section 91 of the Civil Aviation Act 1988, failure to adhere to an airworthiness directive can be considered an offence. Such non-compliance may lead to civil penalties, including fines of up to $153,000 for corporations and $30,600 for individuals. Furthermore, the Civil Aviation Safety Authority (CASA) has the authority to issue a Notice of Jeopardy to the operator, which could lead to the grounding of the aircraft until the required maintenance is performed. Additionally, criminal charges may be pursued, resulting in imprisonment for up to two years, further emphasising the importance of strict compliance with the regulations.
