COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 106 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AlliedSignal (Garrett/AiResearch) Turbine Engines - TPE 331 Series
AD/TPE 331/34 Beryllium Spectrometric Oil Analysis 9/88
CANCELLED.
Background: Revision 1 to GTEC SB TPE 331-72-0530 cancels the requirement to 'SOAP' check for beryllium as the inspection has not proved completely effective in detecting beryllium copper nut erosion. This Directive is therefore cancelled.
Overview
The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority, were amended through Legislative Instrument F2006B07444 to address safety concerns specifically related to AlliedSignal (Garrett/AiResearch) Turbine Engines of the TPE 331 Series. This legislative update responds to identified gaps in engine safety protocols, particularly concerning the detection of beryllium copper nut erosion which previous methods had failed to effectively monitor. The policy objective of this amendment was to ensure that safety measures were both effective and reliable, thereby enhancing the overall safety standards of civil aviation in Australia. The legislative instrument reflects a commitment to continuously improve aviation safety through the cancellation of ineffective inspection directives and the adaptation of safety protocols in response to technological and procedural advancements.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 106, applies to the management of airworthiness directives within the aviation industry in Australia. These regulations govern the standards and procedures that must be adhered to by all parties involved in civil aviation, including aircraft manufacturers, operators, and maintenance providers. The regulations extend their reach to all aircraft registered in Australia, as well as any aircraft operated by Australian entities or individuals within Australian airspace or beyond. Notably, the regulations include a schedule of airworthiness directives, such as AD/TPE 331/34, which pertain to specific types of aircraft engines, in this case, the AlliedSignal (Garrett/AiResearch) Turbine Engines - TPE 331 Series. The directives are designed to ensure that aircraft maintain a safe standard of airworthiness through regular inspections and maintenance procedures. While the regulations are comprehensive, certain exclusions and exemptions may apply, which are detailed within the subordinate instruments and specific directives. This particular directive regarding beryllium spectrometric oil analysis has been cancelled, as noted in Revision 1 to GTEC SB TPE 331-72-0530, due to the inspection method's ineffectiveness in detecting beryllium copper nut erosion.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 106, concern the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives. In this case, the focus is on AlliedSignal (Garrett/AiResearch) Turbine Engines of the TPE 331 series (section (1)). The particular Airworthiness Directive in question is AD/TPE 331/34, which pertains to beryllium spectrometric oil analysis (section (2)). However, it is important to note that this directive has been cancelled (section (3)). The cancellation was prompted by Revision 1 to GTEC SB TPE 331-72-0530, which eliminates the requirement for the 'SOAP' (spectrometric oil analysis programme) check for beryllium. This decision was made because the inspection method had not been entirely effective in detecting beryllium copper nut erosion (section (4)).
Under the Civil Aviation Regulations 1998, the Airworthiness Directives set by CASA are mandatory for all aircraft operators and owners to follow. This includes ensuring that the aircraft and its components meet specific safety standards and requirements as outlined in the Schedule of Airworthiness Directives (section (5)). For the TPE 331 series engines, operators and owners must comply with the directives issued by CASA to ensure the safety and airworthiness of their aircraft. In the case of AD/TPE 331/34, operators and owners were initially required to conduct beryllium spectrometric oil analysis as part of their maintenance procedures. However, following the cancellation of this directive, they are no longer required to perform these checks (section (6)).
Failure to comply with the Airworthiness Directives can result in various consequences. CASA has the authority to take enforcement action against non-compliant aircraft operators and owners, which can include fines, suspension, or revocation of airworthiness certificates (section (7)). Additionally, non-compliance can lead to the grounding of affected aircraft until the required maintenance and inspections are carried out (section (8)). While the specific penalties for non-compliance with AD/TPE 331/34 are not outlined in the text, it is clear that adhering to CASA's directives is crucial to maintaining the safety and airworthiness of aircraft (section (9)).
In summary, the Civil Aviation Regulations 1998, Part 39 - 106, outline the requirements for airworthiness directives, including the now-cancelled AD/TPE 331/34 concerning beryllium spectrometric oil analysis for AlliedSignal (Garrett/AiResearch) TPE 331 series engines. Aircraft operators and owners are obligated to follow these directives to ensure the safety and airworthiness of their aircraft. Non-compliance can result in enforcement action by CASA, including fines, suspension, or revocation of airworthiness certificates, as well as the grounding of affected aircraft (section (10)).
