The above AD is notified in the Commonwealth of Australia Gazette on 26 March 2003.
Overview
The Civil Aviation Safety Regulations 1998, enacted by the Commonwealth of Australia, form a critical part of the regulatory framework designed to ensure the safety of civil aviation within Australia. One of the specific instruments within these regulations is the Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA). This particular AD, AD/DART/30, was introduced to address an identified safety concern with Rolls Royce Dart Series turbine engines. The directive mandates the removal of a specific coating from the turbine disc, which has been found to adversely affect the integrity of the disc. The AD is intended to ensure that these engines meet safety standards by complying with the requirements set out by the German Federal Aviation Office (LBA) Airworthiness Directive 2003-015. This legislative instrument aims to maintain high safety standards in the aviation industry by enforcing necessary actions to correct unsafe conditions identified in specific aircraft components.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically under Part 39 - 106, outlines the scope and application of Airworthiness Directives (AD) within Australia. The particular AD/DART/30 issued for the Rolls Royce Dart Series engines pertains to the removal of the Sermetel coating on turbine discs, mandated due to findings that the coating, along with a dry film lubricant, adversely affects the integrity of the disc. The AD applies to the specified Rolls Royce Dart Series engines as detailed in the requirement document, necessitating corrective action to ensure safety and compliance with international standards, as referenced by the Germany (LBA) Airworthiness Directive 2003-015. The directive is effective from 17 April 2003 and mandates that the specified action be taken by the relevant entities or persons responsible for the maintenance and operation of the affected aircraft engines. The AD extends its reach to all relevant aircraft and aeronautical products within the Australian jurisdiction, thereby enforcing strict compliance with the outlined safety requirements.
Key Provisions
The Civil Aviation Safety Regulations 1998 (CAR 1998) under Part 39, specifically Section 106, establish a framework for Airworthiness Directives (ADs). Section 39.1(1) of the CAR 1998 allows a delegate of the Civil Aviation Safety Authority (CASA) to issue such directives. In this case, an AD has been issued for Rolls Royce Dart Series engines, specifically regarding the turbine disc coating (AD/DART/30). The directive mandates the removal of the Sermetel coating from the turbine disc due to its adverse effect on the disc's integrity, as per the Germany (LBA) Airworthiness Directive 2003-015. The directive came into effect on 17 April 2003, as detailed in the requirement document.
Entities and individuals governed by this AD must ensure compliance with the specified requirements. This includes the timely removal of the identified coating from the turbine disc of the affected Rolls Royce Dart Series engines. The compliance instructions are detailed in the requirement document, which also specifies the effective date of the directive. The delegate of CASA, James Coyne, signed the directive on 5 March 2003, and it was subsequently notified in the Commonwealth of Australia Gazette on 26 March 2003.
Failure to comply with the AD may result in significant legal and operational consequences. The regulations do not explicitly state the penalties for non-compliance, but breaches of civil aviation safety directives can lead to enforcement actions by CASA. This may include fines, operational restrictions, or other regulatory actions deemed necessary to ensure compliance with aviation safety standards. Non-compliance with ADs can also have severe implications for airworthiness and operational safety, potentially leading to aircraft being grounded or prohibited from flight until the required actions are taken.
In summary, the AD mandates the removal of the Sermetel coating from the turbine disc of Rolls Royce Dart Series engines to address safety concerns. Compliance is mandatory for all affected entities, with the directive coming into effect on 17 April 2003. Non-compliance can result in regulatory penalties and operational restrictions, underscoring the importance of adhering to the directive to maintain safety standards in civil aviation.
