Overview
The Civil Aviation Regulations 1998, amended through the legislative instrument F2006B07245, were enacted to address the need for comprehensive safety regulations in civil aviation. This regulation, under Part 39, specifically targets the safety directives for aircraft engines, such as those manufactured by AlliedSignal (Lycoming). The Civil Aviation Safety Authority (CASA) introduced these regulations to ensure the airworthiness of aircraft engines, particularly the T53 Series, by mandating regular inspections and maintenance as per the directives. The policy objective is to maintain and enhance aviation safety by enforcing rigorous standards on engine components, thereby preventing potential failures and ensuring the safe operation of aircraft.
The legislation was enacted by the Commonwealth of Australia, with the aim of filling gaps in the oversight and maintenance of aircraft engines. By specifying directives such as the inspection of power turbine clamping plates in the T53 Series engines, the regulations seek to mitigate risks associated with engine failures. The compliance requirements are aligned with Lycoming Service Bulletin No. 0041 and AD/LYC-T/17, ensuring that all relevant stakeholders adhere to the specified safety standards. This legislative measure underscores the commitment to safeguarding public safety in civil aviation through detailed and enforceable safety directives.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 106, pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives and applies to the AlliedSignal (Lycoming) Turbine Engines - T53 Series. This regulation mandates the inspection of the power turbine clamping plate for certain T53 engines and power turbine rotor assemblies. The directive applies to all T5313A, T5313B, T53-L-13A, and T53-L-13B Series engines as well as power turbine rotor assemblies identified by serial number in Lycoming Service Bulletin (SB) No. 0041, and all spare clamping plates identified by part number 1-140-144-2. The scope of this regulation is thus narrowly focused on specific engine models and components. Compliance with the directive is required as stipulated in paragraph 1Da and 1Db of Lycoming SB 0041. The regulation extends its reach to all entities operating these engines within the Commonwealth of Australia, ensuring adherence to aviation safety standards set by CASA. The Act does not explicitly state exclusions or exemptions, implying that all specified engines and components must comply unless otherwise noted in subordinate instruments.
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39 - 106, include a schedule of airworthiness directives concerning specific aircraft engines. Of note is AD/T53/16, which mandates the inspection of power turbine clamping plates for AlliedSignal (Lycoming) Turbine Engines of the T53 Series (section 1). This directive applies to all T53-13A, T53-13B, T53-L-13A and T53-L-13B Series engines, as well as power turbine rotor assemblies and spare clamping plates identified by serial numbers in Lycoming Service Bulletin No. 0041 (section 2).
The Act imposes certain obligations on the operators and maintainers of these engines. They must ensure that inspections are carried out as per the requirements outlined in paragraph 1Da and 1Db of Lycoming Service Bulletin No. 0041, or AD/LYC-T/17 (section 3). The compliance documentation can be derived from either Lycoming Service Bulletin No. 0041 or AD/LYC-T/17, ensuring that all relevant parties are aware of and adhere to the prescribed inspection protocols.
Failure to comply with these airworthiness directives can lead to serious consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce the regulations, and non-compliance may result in both civil and criminal penalties. While the specific penalties are not detailed in the legislative instrument, they can include fines, operational restrictions, and potential criminal charges against individuals responsible for the oversight of the engines. These consequences underscore the importance of adhering to the directives to maintain the safety and airworthiness of the aircraft involved.
