Overview
The Civil Aviation Regulations 1998, specifically under Part 39, Section 105, include a legislative instrument (F2006B07278) aimed at addressing issues related to airworthiness directives for Aerospatiale (Socata) TB9 and TB10 (Tobago) Series Aeroplanes. This Act was enacted by the Parliament of the Commonwealth of Australia to ensure that civil aviation safety standards are upheld and maintained, thereby addressing potential safety risks associated with in-service aircraft. The problem it addresses is the in-service cracking identified by the manufacturer on these aircraft models, which could potentially compromise the structural integrity and safety of the aeroplanes. The policy objective behind this Act is to mandate regular inspections and necessary modifications to ensure the ongoing airworthiness of these aircraft, thereby protecting the safety of passengers and crew. Compliance with the directive requires specific inspections based on the aircraft's total time in service, ensuring that any issues are identified and rectified promptly.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, apply to the Aerospatiale (Socata) TB9 and TB10 (Tobago) Series Aeroplanes as outlined in AD/TB10/11 Amendment 1 concerning fuselage frame 9. This legislation is applicable to the TB9 and TB10 series aeroplanes with serial numbers 1 to 795 that have not incorporated modification No 70. The regulations govern the conduct and safety standards within the aviation industry, ensuring that all operations comply with prescribed safety directives. The geographic and jurisdictional reach of these regulations is national, encompassing the entire Commonwealth of Australia. There are no specific exclusions or exemptions mentioned within the directive, and it applies to all relevant aircraft within the specified parameters. Compliance with this directive is mandatory and failure to adhere to the outlined requirements could result in safety breaches and potential legal ramifications. The directive also notes that the embodiment of Aerospatiale (Socata) modification No 70 acts as terminating action for this specific directive, thus relieving the need for further inspection for those aircraft that have adopted this modification.
Key Provisions
The key operative sections of the Civil Aviation Regulations 1998 (Part 39 - 105) outline specific safety requirements for the Aerospatiale (Socata) TB9 and TB10 (Tobago) Series Aeroplanes. Section (a) mandates that aircraft with 1500 hours or more total time in service must be inspected before further flight after 9 October 1987. Section (b) requires aircraft with less than 1475 hours total time in service to be inspected within 25 hours of time in service after the same date. Section (c) stipulates that reinspections must occur at each issue of a new Maintenance Release. These requirements are designed to ensure that the fuselage frame of these aircraft is regularly checked for structural integrity, particularly in light of reported in-service cracking on overseas aircraft.
The Act imposes several obligations on the parties and entities it governs. Owners and operators of TB9 and TB10 series aeroplanes must ensure compliance with the specified inspection and maintenance requirements outlined in the AD/TB10/11 Amendment 1. This includes scheduling and performing inspections within the prescribed timeframes and maintaining records of all inspections and maintenance actions taken in accordance with Aerospatiale (Socata) Service Bulletin No 35/1. Additionally, any modifications, such as the embodiment of Aerospatiale (Socata) modification No 70, must be implemented to terminate the action specified in the Directive.
Failure to comply with the Civil Aviation Regulations 1998 can lead to significant consequences. Breaches of these regulations may result in civil penalties, including fines. The maximum penalty for non-compliance can be substantial, reflecting the critical importance of adhering to the safety directives to prevent accidents and ensure the continued airworthiness of the aircraft. Additionally, continued non-compliance could potentially lead to criminal charges, with serious implications for both individual operators and corporate entities involved in the operation of these aircraft.
