AD/MiG 15/2 - Engine Lubricating Oil

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, form a crucial part of the regulatory framework governing aviation safety in Australia. Part 39 of these Regulations, in particular, addresses Airworthiness Directives, which are mandatory rules aimed at ensuring that aircraft, their engines, and related equipment remain in a safe condition for operation. The 1998 Regulations were introduced to consolidate and modernise Australian civil aviation laws, addressing gaps and problems in the previous regulatory framework to enhance aviation safety and efficiency. This legislation is overseen by the Civil Aviation Safety Authority (CASA), which is responsible for enforcing compliance with the Regulations to protect the public and maintain high safety standards in Australian airspace. The policy objective of these Regulations is to ensure that all aircraft and aviation-related equipment operate within safe parameters, thereby safeguarding the travelling public and maintaining the integrity of the national aviation system. One specific instance of this legislative framework in action is found in the Airworthiness Directive concerning Mikoyan and Gurevich (MiG 15) Series Aeroplanes, particularly AD/MiG 15/2, which mandates the withdrawal from service of Lis 2 and Lis-2SB engines that have been operated using synthetic lubricating oil, such as oil manufactured to MIL-L-23699, in contravention of the manufacturers' data. This directive was issued to address the safety concerns associated with the use of non-compliant oil, which could potentially compromise engine performance and reliability. The requirement is that such engines must be withdrawn from service unless they receive explicit approval from the engine manufacturer or CASA, ensuring that only compliant engines are used, thereby maintaining the highest safety standards in aviation operations.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, with a focus on Mikoyan and Gurevich (MiG 15) Series Aeroplanes. The regulation AD/MiG 15/2 pertains to engine lubricating oil, specifically requiring the withdrawal from service of Lis 2 and Lis-2SB engines fitted to SB Lim-2 (MIG 15UTI) aircraft that have been operated using synthetic lubricating oil, such as oil manufactured to MIL-L-23699. These engines can only be returned to service with explicit approval from either the engine manufacturer or the Civil Aviation Safety Authority. Compliance with this directive is mandatory before further flight after 14 August 1993. This regulation applies to aircraft operators and maintenance personnel who must ensure that the specified engines adhere to the outlined requirements to maintain airworthiness standards. The directive’s geographic and jurisdictional reach is national, as it applies throughout Australia under the Commonwealth's authority. There are no stated exclusions or exemptions in this particular directive, and it does not mention the extension or restriction of application through subordinate instruments.

Key Provisions

The primary sections of the Civil Aviation Regulations 1998, specifically PART 39 - 105, address airworthiness directives pertaining to the Mikoyan and Gurevich (MiG 15) Series Aeroplanes. AD/MiG 15/2 mandates the withdrawal from service of Lis 2 and Lis-2SB engines fitted to SB Lim-2 (MIG 15UTI) aircraft if they have been operated using synthetic lubricating oil such as oil manufactured to MIL-L-23699. These engines can only be returned to service with the explicit and specific approval of the engine manufacturer or the Civil Aviation Safety Authority (CASA). Compliance with these directives is mandatory before further flight after 14 August 1993. The obligations imposed by this legislation on the parties governed by it include ensuring that any Lis 2 and Lis-2SB engines on SB Lim-2 (MIG 15UTI) aircraft that have been operated using synthetic lubricating oil are withdrawn from service. Aircraft operators must also seek explicit approval from either the engine manufacturer or CASA before these engines can be returned to service. Failure to comply with these directives could result in the aircraft being deemed unairworthy, potentially leading to grounding of the aircraft until the necessary compliance measures are taken. Under the Civil Aviation Regulations 1998, there are specific consequences for non-compliance with airworthiness directives. Any breach of the requirements stipulated in AD/MiG 15/2 can lead to significant penalties. Although the exact penalties are not detailed in the provided text, it is known that non-compliance with CASA directives can result in substantial fines and potential legal action against the aircraft operator. Additionally, continued operation of an aircraft that does not meet the airworthiness standards set by these directives can lead to the revocation of the aircraft's certificate of airworthiness, which would render the aircraft unable to legally operate.
