COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Eurocopter AS 332 (Super Puma) Series Helicopters
AD/S-PUMA/23 Main Rotor Spindles and Flapping Hinge Pins 9/96
Applicability: Models C, C1, L, and L1 not modified per MOD. 07-43100; and fitted with spindles P/N 332A31-1390-00 to -07, 332A31-1398-00; and all dash number flapping hinge pins P/N 332A31-1380-.
Requirement: Action in accordance with Eurocopter AS332 SB No. 01.00.44.
Note: DGAC AD 96-100-058(B) refers.
Compliance: In accordance with Paragraph 1.D of the Requirement document, with effect from 15 August 1996.
Background: Tests by the manufacturer have discovered that ageing has modified the static and dynamic properties of the frequency adapters, leading to the introduction of considerable loads which reduce the life limits of the spindles and flapping hinge pins. This Directive is to remove from service those spindles and pins that have not been reinforced to cope with the increased loads.
Overview
The Civil Aviation Regulations 1998, as amended by the legislative instrument F2006B07100, are designed to ensure the safety and airworthiness of aircraft operating in Australian airspace. Specifically, Part 39 - 105 of the regulations introduces airworthiness directives that address identified safety concerns in certain aircraft models. This legislative instrument aims to fill the gap in the existing regulatory framework by providing specific safety directives for particular aircraft models and components. The problem it addresses is the degradation of critical components due to ageing, which can lead to catastrophic failure if not addressed. The Australian Parliament enacted these regulations to mandate strict airworthiness standards, thereby enhancing the safety of civil aviation in Australia. The overarching policy objective is to ensure that all aircraft operating in Australian airspace meet the highest safety standards, thereby protecting passengers, crew, and the general public.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Eurocopter AS 332 (Super Puma) series helicopters, including Models C, C1, L, and L1, provided they have not been modified according to MOD. 07-43100 and are fitted with specific main rotor spindles and flapping hinge pins. This Act pertains to the aviation industry and mandates the compliance of helicopter operators with safety directives to mitigate risks associated with ageing components. The geographic reach of this legislation is national, as it is a Commonwealth regulation. There are no stated exclusions or exemptions, and the Act does not specify thresholds. The enforcement and application of this regulation may be extended or restricted through subordinate instruments, which could include further detailed operational requirements or additional conditions for compliance.
Key Provisions
The Civil Aviation Regulations 1998, under PART 39 - 105, specifically addresses the safety requirements for the Eurocopter AS 332 (Super Puma) Series Helicopters through Airworthiness Directives. The particular directive in focus is AD/S-PUMA/23, which concerns the main rotor spindles and flapping hinge pins of certain Super Puma models (section 9/96). The directive applies to models C, C1, L, and L1 that have not been modified according to MOD. 07-43100 and are fitted with specific parts numbers of spindles and flapping hinge pins (section 9/96). The requirement is that these helicopters must adhere to the action stipulated in Eurocopter AS332 SB No. 01.00.44, and compliance must be demonstrated as per the specified document (section 9/96). The directive is informed by tests conducted by the manufacturer that have shown how ageing affects the properties of certain components, potentially leading to significant loads that can reduce the life limits of the spindles and flapping hinge pins (section 9/96).
Entities governed by these regulations must ensure that their Super Puma helicopters comply with the specified airworthiness directive. This involves adhering to the action outlined in Eurocopter's Service Bulletin No. 01.00.44, which likely includes detailed inspection, maintenance, or replacement procedures for the affected components. Compliance must be demonstrated in accordance with Paragraph 1.D of the requirement document, effective from 15 August 1996. The directive is cross-referenced with DGAC AD 96-100-058(B), indicating the international alignment and acceptance of these safety measures (section 9/96).
Failure to comply with these airworthiness directives can result in serious safety hazards. The legislation does not explicitly state offences or penalties within the excerpt, but non-compliance with Civil Aviation Regulations can lead to significant consequences, including potential grounding of the aircraft, fines, and other civil or criminal liabilities. The severity of penalties can vary, but they are designed to ensure that the highest safety standards are maintained in the aviation industry. The specific maximum penalties are not detailed in the provided excerpt but are generally defined in other sections of the Civil Aviation Act and associated regulations.
Given the critical nature of the components and the potential safety risks identified, it is imperative that operators and maintenance personnel strictly follow the outlined procedures and ensure that all required actions are completed in a timely manner. This directive underscores the importance of regular and rigorous inspection and maintenance practices in the aviation sector to prevent accidents and ensure the continued airworthiness of aircraft.
