AD/CJ610/2 - Stage 1 Turbine Wheels

Overview

The Civil Aviation Regulations 1998, specifically within Part 39 – 106 of the Civil Aviation Safety Authority Schedule of Airworthiness Directives, includes a legislative instrument F2006B08566. This particular legislation, AD/CJ610/2, was enacted to address the need for ensuring the safety and reliability of turbine engines in the CJ610 series, particularly focusing on stage 1 turbine wheels. The regulation applies to all CJ610-1, 04, -5 and -6 engine models fitted with certain stage 1 turbine wheels identified by specific part numbers. The compliance requirements are detailed in designated documents, such as the General Electric Alert Service Bulletin or specific Federal Aviation Administration Airworthiness Directives. The objective of this regulation, overseen by the Civil Aviation Safety Authority, is to mitigate potential safety risks associated with these turbine engines, thereby enhancing the overall safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 106, pertain to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives. This legislation applies to all turbine engines of the CJ610 series, particularly those models (CJ610-1, -04, -5, and -6) that are fitted with the specified stage 1 turbine wheels (P/N 634E583P4 and 634E583P4Y). The applicability of this regulation extends to all entities and persons who operate or maintain aircraft equipped with these engines, ensuring that compliance is strictly adhered to across the Commonwealth of Australia. The regulation's scope is reinforced through compliance documents such as General Electric Alert SB (CJ610) A72-70 Addendum 1, FAA AD 73-23-5 Amdt. 39-1742 as amended by Amendment 39-1775, and AD/GE-T/27, which detail the specific requirements and procedures that must be followed. While the regulation itself outlines the primary directives, its enforcement and any additional specifications may be further elaborated through subordinate instruments issued by CASA.

Key Provisions

The Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive (AD) under the Civil Aviation Regulations 1998, specifically targeting the General Electric CJ610 series turbine engines. Section 39-106 of Part 39 details the AD/CJ610/2, which focuses on the stage 1 turbine wheels for CJ610-1, -04, -5, and -6 engine models equipped with part numbers 634E583P4 and 634E583P4Y (section 1). The applicability of this directive is clearly outlined, ensuring that all relevant engines are subject to the compliance requirements stipulated in the AD. In terms of compliance, operators must adhere to the guidance provided in either the General Electric Alert Service Bulletin (SB) (CJ610) A72-70 Addendum 1, the Federal Aviation Administration (FAA) AD 73-23-5 Amendment 39-1742 as amended by Amendment 39-1775, or AD/GE-T/27 (section 2). These documents outline specific procedures and standards that must be followed to ensure the airworthiness of the turbine engines. The directive mandates that the turbine wheels be inspected, tested, and maintained in accordance with the instructions provided in these compliance documents. The AD imposes significant obligations on the parties governed by it. Operators and maintenance personnel must ensure that the stage 1 turbine wheels are inspected and tested as per the specified compliance documents. This includes verifying the structural integrity of the turbine wheels and ensuring that any necessary repairs or replacements are carried out to maintain the airworthiness of the engines. Non-compliance with these requirements can lead to serious safety risks, making it imperative that all directives are strictly followed. Failure to comply with the AD/CJ610/2 can result in serious consequences. Civil and criminal penalties may be imposed for non-compliance, with the potential for significant fines and legal action. The exact penalties are not specified in the text but can be severe, reflecting the critical nature of ensuring the airworthiness of turbine engines. It is therefore essential that operators and maintenance personnel take the directives seriously and implement the required measures to avoid any legal repercussions.
