AD/RRT-S/5 - In-Field Rectification of Low Power Indication - Performance Monitoring

Overview

The Civil Aviation Regulations 1998, as amended through the legislative instrument F2006B06686, were enacted to regulate the operations and safety standards of civil aviation in Australia, and specifically address issues related to the airworthiness of aircraft and their engines. This legislation is administered by the Civil Aviation Safety Authority (CASA), which is tasked with ensuring compliance with safety directives to mitigate risks and enhance the overall safety of civil aviation activities. The specific Airworthiness Directive (AD/RRT-S/5) concerning Rolls Royce Turbine Engines - Spey Series, as detailed in the legislative instrument, addresses a problem related to low power indications and performance monitoring, requiring specific rectifications as outlined in Rolls Royce Service Bulletin No. Sp 71-242. The policy objective is to ensure that aircraft equipped with these engines meet the necessary safety standards, thereby protecting both passengers and personnel involved in aviation operations.

Scope and Application

The Civil Aviation Regulations 1998, specifically under PART 39 - 106, pertains to the Airworthiness Directives, with a particular focus on Rolls Royce Turbine Engines of the Spey series. This legislation applies to all entities operating aircraft equipped with Spey 555-15 engines, mandating them to comply with the Airworthiness Directive AD/RRT-S/5, which concerns in-field rectification of low power indication and performance monitoring. This regulation is integral for ensuring the continued airworthiness and safety of aircraft powered by the specified engines within the Commonwealth of Australia. The directive's scope encompasses all commercial and private operators of aircraft utilising Rolls Royce Spey 555-15 engines, and it mandates adherence to the detailed compliance requirements outlined in Rolls Royce Service Bulletin SB No. Sp 71-242. The Civil Aviation Safety Authority exercises oversight to enforce these standards, ensuring that the specified engines are maintained in a safe and reliable condition. The application of this directive is national, extending across all jurisdictions within the Commonwealth, and it does not specify exclusions or exemptions in the provided text, thereby applying uniformly to all relevant aircraft operators.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, outlines the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives. One of these directives, AD/RRT-S/5, pertains to the Rolls Royce Turbine Engines - Spey Series, focusing on the in-field rectification of low power indications and performance monitoring (section 6/78). The directive applies to the Spey 555-15 engine model and requires compliance with the detailed instructions provided in Rolls Royce Service Bulletin No. Sp 71-242. This means that all affected aircraft operators must follow the specific procedures and guidelines laid out in this service bulletin to ensure the safe and effective operation of the specified engine model. Compliance with AD/RRT-S/5 involves several key obligations for the parties governed by the directive. Primarily, aircraft operators must conduct the necessary in-field rectification of low power indications as per Rolls Royce SB No. Sp 71-242. This includes performing detailed performance monitoring to ensure that the engine operates within the specified parameters. Operators must also maintain records of all rectification actions taken, including dates, personnel involved, and the results of the performance monitoring. Failure to adhere to these requirements can lead to significant safety risks, as low power indications can compromise the overall performance and reliability of the engine, potentially leading to in-flight failures. Failure to comply with the requirements of AD/RRT-S/5 may result in both civil and criminal consequences. Civil penalties for non-compliance can include fines and other financial penalties as stipulated by CASA. In cases where non-compliance leads to safety incidents or accidents, the consequences can be more severe. Criminal charges may be brought against individuals or companies responsible for failing to meet the airworthiness directives, leading to potential imprisonment for those found guilty. The exact penalties can vary depending on the severity of the breach and the impact on aviation safety, but the potential for significant legal and financial repercussions underscores the importance of strict compliance with AD/RRT-S/5.
