Overview

The Civil Aviation Regulations 1998 (CAR 1998), as amended, are pivotal in governing the airworthiness of aircraft and aeronautical products within Australia, overseen by the Civil Aviation Safety Authority (CASA). The 1998 Act was enacted to establish a comprehensive regulatory framework for ensuring the safety of civil aviation. The legislation aims to address the inherent risks associated with air travel by imposing stringent requirements on aircraft maintenance, operations, and design, thereby enhancing the overall safety standards of the aviation industry. One specific Airworthiness Directive issued under this Act is the AD/S-PUMA/46, which was enacted to address a safety issue related to the electric hoists of the Eurocopter AS 332 (Super Puma) Series Helicopters. This directive mandates specific modifications to the wiring of the hoist box to prevent potential failures in the operation of the hoist pyrotechnic squib electrical control. The policy objective of this directive is to mitigate safety risks and ensure the continued airworthiness of the specified helicopter models equipped with the identified hoist system.

Scope and Application

This Airworthiness Directive, issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998, specifically targets Eurocopter AS 332 (Super Puma) series helicopters versions C, C1, L and L1 equipped with a particular optional Breeze 300 lb (136 kg) electric hoist and a 91 M hoist box with part number 332A67-2875-00. The directive mandates identification and, if necessary, modification of the hoist box wiring as detailed in Eurocopter AS 332 Alert Service Bulletin No. 25.01.18 to prevent the failure of the hoist pyrotechnic squib electrical control. This modification must be completed within the next 100 hours of time in service or two months, whichever occurs first, following the directive's effective date of 8 January 2003, or before installing a replacement 91 M hoist box. This directive applies nationally and is intended to ensure the safety of aircraft operation by addressing an identified unsafe condition.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39, specifically in Section 105, detail the provisions of the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. Section 39.1(1) empowers CASA to issue directives to ensure aircraft and aeronautical products maintain their airworthiness. In this context, the AD/S-PUMA/46 pertains to Eurocopter AS 332 (Super Puma) Series Helicopters, particularly those equipped with the optional Breeze 300 lb (136 kg) electric hoist and a specific 91 M hoist box part number (P/N) 332A67-2875-00. This directive mandates identifying and, if necessary, modifying the hoist box wiring to prevent the failure of the Breeze hoist pyrotechnic squib electrical control. The directive applies to AS 332 helicopters versions C, C1, L, and L1. The AD/S-PUMA/46 obligates the operators of the specified AS 332 helicopters to adhere to the requirements outlined in the directive. Operators must identify the part number of the hoist box wiring following paragraphs 2.B.1 to 2.B.2.b of Eurocopter AS 332 Alert Service Bulletin (ASB) No. 25.01.18. Depending on the identified part number, they must modify the wiring in accordance with paragraphs 2.B.2.c, 2.B.2.d, 2.B.2.e, or 2.B.2.f of the ASB. These modifications must be completed within the next 100 hours time in service (TIS) or two months, whichever comes first, after the effective date of the directive or before installing a spare 91 M hoist box. Failure to comply with these obligations could result in unsafe conditions that compromise the airworthiness of the aircraft. Failure to comply with the AD/S-PUMA/46 may result in significant consequences. While the Civil Aviation Regulations 1998 do not explicitly state specific offences or penalties for non-compliance with airworthiness directives, non-compliance generally constitutes a breach of the regulations. Such breaches can lead to enforcement actions by CASA, including the potential for the aircraft to be grounded until the required modifications are made. Additionally, persistent non-compliance could result in civil or criminal penalties as per other sections of the Civil Aviation Act 1988, and severe cases could lead to prosecution under criminal law, with penalties including fines and imprisonment. The specific consequences would depend on the nature and extent of the non-compliance and any resultant harm or risk to aviation safety.
