AD/S-PUMA/15 Amdt 1 - Sling Installation - 3 Ton Cargo Hook

Overview

The Civil Aviation Regulations 1998, which were enacted by the Australian Parliament, aim to ensure the safety and efficiency of civil aviation within Australia. Specifically, Part 39 of the Regulations deals with airworthiness directives, which are legally enforceable rules regarding the design, production, and maintenance of aircraft. These regulations fill a critical gap by providing a structured approach to addressing safety issues that may arise in the aviation sector. The policy objective of these regulations is to maintain the highest possible safety standards in civil aviation, ensuring the protection of passengers, crew, and the general public. One specific directive under these regulations is AD/S-PUMA/15Amdt 1, which concerns the Eurocopter AS 332 (Super Puma) Series Helicopters. This directive mandates the replacement of a mechanical emergency jettison control component (P/N AS22-25) with a new control (P/N AS22-12) to prevent uncommanded load jettison. This amendment was introduced to enhance safety by addressing potential mechanical failures that could lead to hazardous situations. The amendment reflects the ongoing commitment to updating and improving safety standards based on new information and technological advancements.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the authority of the Civil Aviation Safety Authority, applies to the Eurocopter AS 332 (Super Puma) Series Helicopters, namely models C, C1, L, and L1 that are equipped with a sling installation featuring a cargo hook part number AS21-7 and a mechanical emergency jettison control part number AS22-25. This regulation requires the replacement of the existing mechanical emergency jettison control with a control part number AS22-12. The directive mandates compliance with this change prior to the next use of the cargo hook after 27 July 1994, with the amendment coming into effect on 10 November 1994. The directive aims to prevent uncommanded load jettison, and references the DGAC AD 94-150-052(B)R1 and Eurocopter Service Bulletin No. 01-38 R1 for further information. The regulation applies nationally within Australia, enforcing safety standards across all states and territories. There are no stated exclusions or exemptions within the scope of this directive, and compliance is mandatory for the specified helicopter models and configurations.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes a schedule of airworthiness directives (ADs) which mandate certain safety measures for aircraft operations. One such directive pertains to the Eurocopter AS 332 (Super Puma) series helicopters, focusing on the installation of a 3-ton cargo hook (AD/S-PUMA/15 Amendment 1). This directive applies to models C, C1, L, and L1 of the Super Puma helicopters that are equipped with a sling installation featuring a cargo hook part number AS21-7 and a mechanical emergency jettison control part number AS22-25. The key requirement is the replacement of the existing mechanical emergency jettison control (P/N AS22-25) with a new control (P/N AS22-12). This change is intended to prevent uncommanded load jettison, enhancing the safety of operations involving the cargo hook. The AD imposes clear obligations on the operators of these helicopters. They must ensure that the specified mechanical emergency jettison control is replaced with the new control as per the directive. This replacement must be carried out before the next use of the cargo hook after 27 July 1994. The compliance requirement underscores the urgency and importance of adhering to the directive to maintain the airworthiness and safety standards of the aircraft. Operators must also reference relevant documents such as DGAC AD 94-150-052(B)R1 and Eurocopter Service Bulletin No. 01-38 R1 for additional guidance and technical details. Failure to comply with the provisions of this airworthiness directive can result in serious consequences. The Civil Aviation Regulations 1998 outline various penalties for non-compliance with ADs. While the specific penalties are not detailed in the text, it is understood that breaches can lead to enforcement actions, which may include fines, suspension or revocation of airworthiness certificates, and other regulatory sanctions. Operators are expected to rigorously adhere to the directive to avoid these penalties and to ensure the continued safety and airworthiness of their aircraft.
