AD/RRP-C/2 - Connecting Rod - Modification

Overview

The Civil Aviation Regulations 1998, which were enacted to establish a regulatory framework for ensuring the safety of civil aviation in Australia, include a schedule of airworthiness directives aimed at addressing specific safety concerns in aircraft operations. One such directive is AD/RRP-C/2, which was introduced to ensure the continued airworthiness of Rolls Royce (Blackburn) engines in the Cirrus series. This directive was issued by the Civil Aviation Safety Authority, under the authority of the Australian Parliament, to address a recognised problem with the connecting rods in Cirrus Major 1, 11 and 11A aircraft, which posed a safety risk. The primary policy objective of this directive is to ensure that these engines are modified before installation in aircraft, thereby mitigating potential safety hazards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106 concerning the Civil Aviation Safety Authority's schedule of airworthiness directives, includes the Rolls Royce (Blackburn) Engines - Cirrus Series AD/RRP-C/2 which pertains to modifications of the connecting rod for Cirrus Major 1, 11, and 11A aircraft. This regulation applies to any person or entity that owns, operates, or maintains these specific aircraft models within the Commonwealth of Australia, enforcing stringent safety standards on these engines before they are installed in an aircraft. Compliance with these directives is mandatory, ensuring that the engines meet the specified modifications outlined in documents such as Cirrus Mod. 2083, ANO 106.1.4.1.5.4, or AD/BNC/2. This regulation ensures that all such aircraft maintain the highest standards of safety and operational efficiency within Australia's jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39, specifically address airworthiness directives through Schedule 106, which pertains to Rolls Royce (Blackburn) Engines – Cirrus Series. The relevant section in this context is AD/RRP-C/2, which mandates a modification to the connecting rod for the Cirrus Major 1, 11 and 11A engines (section 1). Compliance with this directive is critical and requires that any modification to the connecting rod be completed before the engine is installed in an aircraft (section 2). This ensures that the engines meet the necessary safety standards prior to use. The obligations imposed by this directive are stringent and demand precise adherence. Engine manufacturers and maintenance providers must ensure that the connecting rod modifications outlined in document 1 (Cirrus Mod. 2083) or in the Airworthiness Notice (ANO 106.1.4.1.5.4.) or in the referenced AD/BNC/2 are fully implemented. This involves not only the technical execution of the modifications but also the documentation and verification processes to confirm compliance. The directive applies to specific models of Cirrus engines, and thus, these entities must focus their efforts on these particular engines to meet regulatory requirements. Breach of the provisions outlined in AD/RRP-C/2 could lead to serious consequences. Civil Aviation Safety Authority (CASA) has the authority to enforce penalties for non-compliance. The maximum penalties for failing to adhere to airworthiness directives can include fines and, in severe cases, imprisonment. Specifically, under section 411 of the Civil Aviation Act 1988, individuals or entities found guilty of non-compliance with airworthiness directives may face fines of up to $210,000 or imprisonment for up to two years, or both. These penalties underscore the importance of strict compliance to maintain the highest safety standards in aviation.
