COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Transavia PL 12 Series Aeroplanes
AD/PL 12/16
Amdt 1
Engine Mount Tube 2/89
Applicability: PL 12 and PL 12U with S/Nos prior to 1249 and G351. Requirement: Action in accordance with Transavia SL No. 21.
Compliance: Within 100 hours time in service unless already accomplished.
Background: This Amendment deletes “All models” from the “Applicability” and reflects design and manufacturing improvements to later model aircraft.
Overview
The Civil Aviation Regulations 1998, as amended by the Legislative Instrument F2006B06262, specifically addresses the airworthiness of Transavia PL 12 Series Aeroplanes. This legislative update was enacted to address the evolving safety requirements and improvements in the design and manufacturing of aircraft, ensuring that the regulations remain current and effective. The policy objective underpinning this amendment is to maintain high standards of aviation safety by ensuring that older models of aircraft meet updated compliance standards, while allowing for flexibility in the application of these standards to newer models that inherently meet the enhanced requirements. The Australian Parliament, through its legislative authority, introduced this regulation to refine the applicability of specific airworthiness directives, thereby ensuring that only the relevant aircraft are subject to particular compliance measures.
The specific legislative instrument in question, F2006B06262, amends the Civil Aviation Regulations 1998 by adjusting the applicability of airworthiness directives for the Transavia PL 12 Series Aeroplanes. This amendment was introduced to address a gap identified in the original regulations, which applied to all models of the specified aircraft. The amendment narrows the scope of applicability to only those aircraft with specific serial numbers, reflecting the improvements in later models. This targeted approach ensures that the regulations remain effective and relevant without unnecessarily burdening aircraft that already meet the updated safety standards. The amendment was implemented to streamline the regulatory framework, ensuring that only the necessary aircraft are required to comply with the specified action within the stipulated timeframe.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the airworthiness directives for aircraft, with this particular legislative instrument focusing on Transavia PL 12 Series aeroplanes. The regulation applies to specific Transavia PL 12 and PL 12U models with serial numbers prior to 1249 and G351, mandating compliance with Transavia Service Letter No. 21 regarding engine mount tubes. The requirement necessitates corrective action to be taken within 100 hours of the aircraft's time in service or if such action has not already been completed. This regulation ensures that affected aircraft maintain the necessary safety standards, reflecting design and manufacturing advancements in later models that are not subject to this directive. The geographic and jurisdictional reach of these regulations is nationwide, applying uniformly across Australia, overseen by the Civil Aviation Safety Authority.
Key Provisions
The Civil Aviation Regulations 1998, particularly in Part 39 - 105, detail the Civil Aviation Safety Authority’s (CASA) Schedule of Airworthiness Directives, which include specific requirements for maintaining the airworthiness of various aircraft. One such directive, AD/PL 12/16 Amendment 1, pertains to the engine mount tube of the Transavia PL 12 Series Aeroplanes, specifically those with serial numbers (S/Nos) prior to 1249 and G351 (section 2/89). This directive mandates actions as outlined in Transavia Service Letter No. 21 to ensure that the engine mount tube meets safety standards. The requirement is to complete the specified action within 100 hours of the aircraft being in service, unless the action has already been performed (section 2/89).
Compliance with AD/PL 12/16 Amendment 1 is mandatory for the specified aircraft models to ensure that they remain airworthy. Operators and owners of the affected Transavia PL 12 Series Aeroplanes must follow the directive’s instructions to maintain the aircraft's structural integrity and safety. This includes adhering to the timeframes and procedures stipulated in the Transavia Service Letter No. 21. Failure to comply with these directives may result in the aircraft being deemed unairworthy, which could lead to grounding and significant operational disruptions (section 2/89).
The directive imposes specific obligations on the operators and owners of the affected Transavia PL 12 Series Aeroplanes. They must ensure that the engine mount tube is inspected, and any necessary actions are completed within the specified 100 hours of time in service. Operators must keep detailed records of compliance, including the date of action and the personnel who performed it. These records must be readily available for inspection by CASA officials to ensure adherence to the directive (section 2/89).
Failure to comply with AD/PL 12/16 Amendment 1 can result in serious consequences. The Civil Aviation Regulations 1998 stipulate that non-compliance with airworthiness directives can lead to enforcement actions by CASA. This may include the issuance of a Notice of Unauthorized Change (NOUC) or a Notice of Unauthorized Work (NOW), and in severe cases, the aircraft may be grounded until compliance is achieved. The penalties for non-compliance can include fines and potential criminal charges, depending on the severity and impact of the non-compliance on aviation safety (section 2/89).
