AD/RRP-C/1 - Connecting Rod - Modification

Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 106, addresses the need for ensuring the airworthiness of aircraft engines through the issuance of Airworthiness Directives (ADs). This legislative instrument, enacted by the Commonwealth of Australia, is designed to maintain high safety standards within the aviation sector by mandating modifications and compliance checks for specific engine components. The policy objective is to mitigate risks associated with engine failure, thereby enhancing overall flight safety. The Civil Aviation Safety Authority, through this regulation, enforces modifications for Rolls Royce (Blackburn) Engines – Cirrus Series, specifically targeting the connecting rod to prevent potential failures. The legislation applies to Cirrus Minor 1, 11, and 11A models and requires compliance with specified modifications before the engines can be installed in aircraft. This ensures that the engines meet stringent safety criteria, protecting both passengers and crew.

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 of aircraft operations within Australia. One such directive, AD/RRP-C/1, pertains to the modification of the connecting rod for Rolls Royce (Blackburn) Engines of the Cirrus Series, namely the Cirrus Minor 1, 11, and 11A models. This directive is applicable to any aircraft equipped with the specified engines and requires compliance before installation in an aircraft. The directive references relevant documents such as Cirrus Mod. M1613, Cirrus Service Instruction No. J32, ANO 106.1.4.1.5.3, or AD/BNC/1, to ensure that the modifications meet the necessary safety standards. The directive applies to aircraft registered in Australia and operating under Australian law, enforcing stringent safety measures for the specified engines to mitigate any potential risks.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, contain an Airworthiness Directive (AD) pertaining to Rolls Royce (Blackburn) Engines of the Cirrus Series, identified as AD/RRP-C/1. This AD mandates modifications to the connecting rod for the Cirrus Minor 1, 11, and 11A engines. The directive references several documents that outline the compliance requirements: Cirrus Mod. M1613 and Cirrus Service Instruction No. J32, ANO 106.1.4.1.5.3, or AD/BNC/1. Compliance with these modifications is required before the engine is installed in an aircraft. The AD imposes several obligations on the parties and entities it governs. Primarily, it requires that the connecting rod modifications outlined in the referenced documents be completed before the engine is installed in a Cirrus Minor 1, 11, or 11A aircraft. This ensures that the engines meet the necessary airworthiness standards and reduces the risk of in-flight failures. The directive also mandates that any modifications be carried out by authorised personnel or entities who are familiar with the specifications and requirements detailed in the referenced documents. Failure to comply with the AD/RRP-C/1 can lead to serious consequences. The Civil Aviation Safety Authority (CASA) may take enforcement action against any party or entity that does not adhere to the directive. This can include fines, legal action, or even the grounding of affected aircraft until the modifications are completed. The exact penalties are not specified in the AD itself, but they can be severe, given the potential safety implications of non-compliance with airworthiness directives. Therefore, it is imperative for operators and maintenance personnel to ensure that all modifications are carried out in accordance with the specified requirements.
