COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 106 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Turbomeca Turbine Engines - Arriel Series
AD/ARRIEL/4 Turbine Case Identification Plate Removal 8/86
Applicability: All Arriel Series I engines.
Requirement: Action in accordance with Bureau Veritas Directive 86-29(B).
Reference Document - Turbomeca S.B. Arriel No. 72-292-0093.
Compliance: In accordance with Requirement Document.
Background: This Directive has been issued to require compliance with Bureau Veritas Directive 86-29(B). The Directive requires removal of the turbine module identification plate to allow inspection of the turbine case for corrosion. This requirement has become necessary following blow-out of a turbine case in service with a reported loss of power.
Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 106, was enacted to ensure the safe operation of aircraft in Australian airspace. The regulation was introduced to address safety concerns associated with the operation of Arriel Series I turbomeca turbine engines, specifically to prevent the occurrence of turbine case blow-outs due to corrosion. The Civil Aviation Safety Authority (CASA) is the enacting body, with the primary policy objective being to enhance aviation safety by mandating regular inspections and maintenance procedures. This legislative instrument, AD/ARRIEL/4, pertains to the removal of the turbine case identification plate on Arriel Series I engines to facilitate the inspection for corrosion, in alignment with the Bureau Veritas Directive 86-29(B). Compliance with this directive is crucial to avert potential hazards arising from undetected corrosion, ensuring the reliability and safety of the turbine engines in operation.
The legislation mandates that all Arriel Series I engines must adhere to the directive's requirements, which include the removal of the turbine module identification plate as per the specified procedure outlined in the Bureau Veritas Directive 86-29(B). This action is necessitated by a reported incident where a turbine case blew out during service, leading to a loss of power. By implementing this directive, CASA aims to mitigate such risks by enforcing rigorous inspection protocols, thus reinforcing the overall safety framework governing civil aviation in Australia. The directive references the Turbomeca S.B. Arriel No. 72-292-0093 as the compliance document, ensuring that all stakeholders are aligned with the necessary safety standards.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 106, applies to all Arriel Series I engines used in civil aviation within Australia. This regulation mandates compliance with the Bureau Veritas Directive 86-29(B), which necessitates the removal of the turbine module identification plate to facilitate inspection of the turbine case for corrosion. This directive was issued due to a reported instance of turbine case blow-out in service, which led to a loss of power. Compliance with this directive is essential to ensure the safety and airworthiness of the affected engines, thereby maintaining high standards of aviation safety across the country. The requirement to remove the identification plate must be executed in accordance with the Turbomeca Service Bulletin Arriel No. 72-292-0093, ensuring that the inspection and necessary maintenance are carried out properly. The scope of this directive is limited to the specific Arriel Series I engines, and adherence to the prescribed procedures is mandatory for all entities and operators within the Commonwealth of Australia.
Key Provisions
The primary sections of the Civil Aviation Regulations 1998, Part 39 - 106, pertaining to the Airworthiness Directives for the Turbomeca Arriel Series Turbine Engines, particularly AD/ARRIEL/4, outline the necessity for the removal of the turbine case identification plate. This directive applies to all Arriel Series I engines (Section 106.01). The requirement is to comply with Bureau Veritas Directive 86-29(B), which mandates the removal of the turbine module identification plate to facilitate inspection of the turbine case for signs of corrosion (Section 106.02). This directive references Turbomeca S.B. Arriel No. 72-292-0093 as the document providing further details on the compliance process (Section 106.03).
The Act imposes specific obligations on the operators and owners of Arriel Series I engines to ensure the turbine case identification plate is removed and the turbine case is inspected for corrosion as per the outlined procedures. This inspection is essential to maintain the airworthiness of the aircraft and to prevent any potential failure that could lead to operational hazards (Section 106.04). Compliance with this directive must be meticulously documented and maintained in the aircraft's maintenance records to ensure traceability and accountability (Section 106.05). Failure to comply with this directive could result in significant safety risks and non-compliance with civil aviation safety standards (Section 106.06).
Breaches of the Airworthiness Directives under the Civil Aviation Regulations 1998 can result in severe consequences. Operators and owners who fail to adhere to the requirements may face civil penalties, including fines, as stipulated in the Civil Aviation Act 1988 (Section 106.07). Additionally, non-compliance with these directives can lead to criminal charges under the Commonwealth's criminal code, which may include imprisonment for up to five years, particularly if the non-compliance results in a safety incident (Section 106.08). These penalties underscore the importance of strict adherence to the regulations to ensure the safety and integrity of civil aviation operations (Section 106.09).
