AD/DART/11 - Control Box Mounting Bolts - Inspection

Overview

The Civil Aviation Regulations 1998, amended through the legislative instrument F2006B08698, introduced specific safety directives aimed at ensuring the airworthiness of Rolls Royce Turbine Engines of the Dart Series. This regulation, enacted by the Australian Government, targets the Dart RDa-6 and RDa-7 series engines and was designed to address issues related to control box mounting bolts. The problem it seeks to resolve involves ensuring the structural integrity and operational safety of these engines, which is critical for maintaining compliance with international aviation safety standards. The objective of this directive is to mandate immediate inspection and corrective actions to mitigate potential risks associated with the specified components of the engines, thus ensuring the safety and reliability of civil aviation operations within Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106, mandates the application of Airworthiness Directives (ADs) pertaining to Rolls Royce Turbine Engines, particularly the Dart Series. This legislation applies to all Dart RDa-6 and RDa-7 series engines, imposing stringent requirements for the inspection of control box mounting bolts. The directive demands compliance with either Rolls Royce Service Bulletin SB Da 76-A17 Rev 1 or another specified directive, AD/RRT/25, ensuring the maintenance and safety of these aviation components. The AD takes effect immediately upon issuance, reflecting the urgency and importance of adhering to these safety protocols. Jurisdictionally, this regulation operates under the Commonwealth of Australia, overseen by the Civil Aviation Safety Authority (CASA), thereby extending its reach to all entities and persons involved in the operation or maintenance of these engines within Australia. While the ADs themselves are comprehensive, the scope and application may be further extended or refined through subordinate instruments issued by CASA.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, include detailed provisions governing the airworthiness directives for various aircraft components, such as the Rolls Royce Turbine Engines - Dart Series. This legislative instrument mandates that all Dart RDa-6, RDa-7 series engines must undergo an inspection of the control box mounting bolts (AD/DART/11). The directive specifies that this inspection must be carried out either in accordance with Rolls Royce Service Bulletin SB Da 76-A17 Rev 1 or as per AD/RRT/25. The requirement is effective immediately, ensuring that the inspection is conducted forthwith. The obligations imposed by these regulations are clear and direct. Operators and maintainers of the affected Dart series engines must ensure that the inspections are carried out as specified. This includes reviewing and implementing the procedures outlined in Rolls Royce's SB Da 76-A17 Rev 1 or AD/RRT/25. These directives provide detailed steps and criteria for conducting the inspection, ensuring that the control box mounting bolts are checked for any defects or issues that could compromise the engine's safety and airworthiness. Failure to comply with these directives could result in significant safety risks and potential non-compliance with civil aviation safety standards. Non-compliance with the airworthiness directives can lead to serious consequences, both civil and criminal. Under the Civil Aviation Regulations 1998, any breach of the specified inspection requirements can be considered an offence. The potential penalties for such breaches include substantial fines and, in severe cases, imprisonment. The exact penalties can vary based on the severity of the breach and the specific provisions of the regulations, but they are designed to enforce strict adherence to safety standards. The overarching aim is to ensure that all Dart RDa-6 and RDa-7 series engines are maintained to the highest safety standards, thereby protecting both the aircraft and the occupants.
