AD/DART/19 - Combustion Air Casing Anti-Tear Straps

Overview

The Civil Aviation Regulations 1998, specifically in Part 39 - 106, address the overarching safety standards for civil aviation in Australia. The legislation was enacted by the Parliament of Australia to ensure the safety and efficiency of civil aviation, and it is administered by the Civil Aviation Safety Authority (CASA). This legislative instrument, F2006B08704, focuses on Rolls Royce Turbine Engines - Dart Series and pertains to the safety directive AD/DART/19 regarding the Combustion Air Casing Anti-Tear Straps for Dart RDa-6 and RDa-7 series engines. The policy objective of this directive is to mandate specific actions to be undertaken by engine operators to maintain the airworthiness of these engines, thereby ensuring compliance with established safety standards. The directive requires adherence to either Rolls Royce SB Da 72-475 Rev 1 or AD/RRT/32 Amdt 1 as outlined in the Requirement Document, and compliance is to be achieved in accordance with the specified actions.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 – 106, pertain to the Civil Aviation Safety Authority’s (CASA) Schedule of Airworthiness Directives. This regulation applies to all Rolls Royce Dart RDa-6 and RDa-7 series engines used in civil aviation. The requirement outlined in the legislation mandates that the specified engines must comply with either Rolls Royce Service Bulletin SB Da 72-475 Revision 1 or AD/RRT/32 Amendment 1. Compliance with these directives is imperative to ensure the continued airworthiness of the engines, and the specific actions to be taken are detailed in the respective requirement documents. This legislation forms part of the broader regulatory framework administered by CASA, which has jurisdiction across the Commonwealth of Australia, ensuring that all civil aviation activities within the country meet the necessary safety standards. The regulation does not specify exclusions, exemptions, or thresholds, and its application is direct and non-negotiable for the specified engines. Any extensions or restrictions to its application would typically be detailed in subordinate instruments issued by CASA.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, include a Schedule of Airworthiness Directives that govern the maintenance and safety standards for various aircraft components. In this context, AD/DART/19 addresses the Rolls Royce Turbine Engines - Dart Series, focusing on combustion air casing anti-tear straps. This directive applies to all Dart RDa-6 and RDa-7 series engines (Section 11/87). The requirement under this directive is for the engines to either adhere to the action specified in Rolls Royce Service Bulletin SB Da 72-475 Rev 1 or comply with the amendments detailed in AD/RRT/32 Amendment 1 (Section 1). Compliance is to be achieved as per the detailed instructions provided in the Requirement Document (Section 2). This legislation imposes specific obligations on the parties responsible for the maintenance and operation of the affected aircraft engines. Owners and operators must ensure that the appropriate action is taken on their Dart RDa-6 and RDa-7 series engines in accordance with the specified Rolls Royce bulletin or the amended directive. This includes conducting necessary inspections, repairs, and replacements as outlined in the Requirement Document to maintain the airworthiness of the engines. The onus is on these parties to verify that their engines meet the safety standards set forth in the directive to avoid any potential safety risks. Failure to comply with the provisions outlined in AD/DART/19 could lead to significant consequences. While the specific penalties for non-compliance are not detailed in the excerpt, the overarching Civil Aviation Regulations 1998 provide a framework that includes both civil and criminal penalties for breaches of airworthiness directives. In general, such breaches may result in fines, imprisonment, or both, depending on the severity and impact of the non-compliance. It is crucial for all parties involved to adhere strictly to the requirements to avoid these potential legal repercussions.
