AD/RB211/29 Amdt 1 - LP Compressor Blades

Overview

The Civil Aviation Regulations 1998 (CAR 1998) is a comprehensive piece of legislation designed to govern the safety and operational standards of civil aviation in Australia. Enacted by the Parliament of Australia, these regulations address significant safety concerns by ensuring that aircraft and aeronautical products meet necessary safety standards. The specific problem or gap this legislation aims to address includes the need for consistent and stringent safety measures to prevent accidents and ensure the safety of passengers and crew. One of the key elements of the CAR 1998 is the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA). These directives are crucial in responding to identified safety issues by mandating specific actions to be taken by aircraft operators and owners to correct unsafe conditions. For instance, Airworthiness Directive AD/RB211/29, which was subsequently amended, was introduced to tackle issues related to the durability of certain fan blades in Rolls Royce RB211-524 Series engines. This directive was intended to ensure that any damage to these blades, which could compromise their durability, is identified and rectified through inspection and removal procedures as outlined in the Rolls Royce Mandatory Service Bulletin.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 106 Civil Aviation Safety Authority Schedule of Airworthiness Directives, addresses safety concerns regarding certain aircraft components. This legislative instrument applies to the Rolls Royce RB211-524 Series engines, mandating the removal and inspection of particular fan blades to ensure airworthiness and safety. The directive is issued under the authority of the Civil Aviation Safety Authority (CASA) and is enforceable across the Commonwealth of Australia. This AD aims to rectify a safety issue identified in the blades that may have been damaged during a repair process, potentially compromising the durability and integrity of the engine components. Compliance with the directive is mandatory for all entities operating these engines within Australia, and failure to adhere to the specified requirements can result in non-compliance with civil aviation safety standards. The Airworthiness Directive AD/RB211/29, as amended, includes specific serial numbers of affected fan blades and introduces a compliance deadline, reinforcing the importance of timely action to maintain the safety standards of the aircraft. The directive became effective on 5 September 2002, with Amendment 1 extending the applicability to additional blade serial numbers and setting a clear timeframe for compliance. This regulatory action extends to any person or entity operating the specified Rolls Royce RB211-524 Series engines within Australian jurisdiction, ensuring a uniform approach to addressing the identified safety issue. The directive is notified in the Commonwealth of Australia Gazette, thereby providing official publication and enforcing the legislative mandate.

Key Provisions

The Airworthiness Directive (AD) AD/RB211/29 Amdt 1, issued by the Civil Aviation Safety Authority (CASA) under section 39.1(1) of the Civil Aviation Regulations 1998, specifically targets Rolls Royce RB211-524 Series engines. The AD applies to certain fan blades (section 1(a)) that are identified in the requirement section as needing to be removed and inspected in accordance with the procedures outlined in Rolls Royce Mandatory Service Bulletin RB.211-72-D184 Rev 2 (section 1(b)). This action is to be carried out under the circumstances and according to the instructions detailed in the requirement section (section 1(b)) and must be completed by the time specified in the compliance section (section 1(c)). The directive is effective from 5 September 2002. The AD imposes obligations on the entities governed by it to ensure that the specified Rolls Royce RB211-524 Series engines are inspected according to the outlined procedures. This involves the removal and detailed inspection of certain fan blades, which is necessary to identify any damage that could potentially compromise the safety and airworthiness of the aircraft. The inspection must adhere to the procedures stipulated in Rolls Royce's Mandatory Service Bulletin RB.211-72-D184 Rev 2, as referenced in the requirement section. The compliance with this AD is critical to maintaining the safety standards set by the Civil Aviation Regulations 1998. Breach of the requirements set out in the AD AD/RB211/29 Amdt 1 could lead to significant civil or criminal consequences. While the Civil Aviation Regulations 1998 do not explicitly detail the specific penalties for non-compliance with ADs, non-compliance with aviation safety regulations generally can result in severe penalties. These may include fines, legal action, and potential grounding of the aircraft until the compliance issues are rectified. Additionally, the operator or owner of the aircraft may face operational restrictions or suspension of their air operator certificate, which could have a substantial impact on their business operations. It is crucial for the governed entities to adhere to these directives to avoid such severe repercussions.
