AD/TURMO/2 - Oil Scavenge Hose - Life Limitation

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 106, which includes the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, was enacted to address the need for stringent and uniform safety standards in civil aviation, particularly in relation to the airworthiness of aircraft components and engines. The legislation, overseen by the Parliament of the Commonwealth of Australia, aims to ensure that all aircraft, their components, and parts are maintained in a safe and airworthy condition, thus protecting public safety and promoting the integrity of the aviation industry. One specific airworthiness directive under this legislation, AD/TURMO/2, focuses on the oil scavenge hoses of Turbomeca Turmo Series engines, establishing a life limitation to mitigate risks associated with wear and potential failure of these critical components. This directive applies to certain Turmo engines and mandates compliance with Turbomeca Service Letters to ensure continued airworthiness.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106, mandates the application of airworthiness directives issued by the Civil Aviation Safety Authority (CASA) to ensure the safety and airworthiness of aircraft engines within Australia. This legislative instrument, AD/TURMO/2, applies to Turbomeca Turmo series turbine engines, including models Turmo 111 C3, C5, C6, E3, and E6. The directive requires adherence to either Turbomeca Service Letter No. 196/70/35 or Airworthiness Directive TURB-T/4, which includes detailed compliance instructions. The geographic and jurisdictional reach of this regulation is national, as it applies to all aircraft engines within the Commonwealth of Australia, ensuring consistent safety standards across the country. The regulation does not specify any exclusions or exemptions, implying that all specified engines must comply with the outlined directives. The application of this Act may be extended or clarified through subordinate instruments issued by CASA.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 106 Civil Aviation Safety Authority Schedule of Airworthiness Directives, includes AD/TURMO/2 concerning the oil scavenge hose for Turbomeca Turmo Series engines (section 1). This directive applies to Turbomeca Turmo 111 C3, C5, C6, E3, and E6 engines (section 2). The primary requirement of this directive is compliance with either Turbomeca SL No. 196/70/35 or AD/TURB-T/4, as detailed in the relevant requirement document (section 3). The obligations under AD/TURMO/2 mandate that owners and operators of the specified Turbomeca Turmo engines must ensure the oil scavenge hose meets the life limitation requirements as outlined in the referenced documents (section 4). This includes conducting regular inspections and maintenance to verify that the hose is within the specified limits and conditions for continued safe operation (section 5). Non-compliance with these directives can lead to serious safety hazards, thus it is imperative for operators to adhere strictly to the specified requirements (section 6). Failure to comply with AD/TURMO/2 can result in significant consequences. The Civil Aviation Safety Authority (CASA) may take enforcement action against non-compliant operators, which could include fines and other penalties (section 7). In severe cases, CASA has the authority to suspend or revoke the airworthiness certificate of the aircraft, effectively grounding it until the necessary corrective actions are taken (section 8). Additionally, operators may face legal liability for any accidents or incidents resulting from non-compliance with these directives (section 9).
