AD/DAUPHIN/33 - Lucas Air Equipment Hoist - Explosive Squib

Overview

The Civil Aviation Regulations 1998, established by the Commonwealth of Australia, provide a comprehensive regulatory framework to ensure the safety and efficiency of civil aviation within the country. Among the numerous provisions, Part 39 - 105 of these regulations specifically addresses the safety directives for various aircraft, including the Eurocopter SA 360 and SA 365 (Dauphin) Series Helicopters. Enacted by the Australian Parliament, the objective of this legislation is to address safety concerns and ensure the airworthiness of aircraft through the issuance of specific directives. One such directive, AD/DAUPHIN/33, pertains to the Lucas Air Equipment hoist in Dauphin series helicopters, highlighting the necessity to prevent potential pyrotechnic squib issues that could compromise safety during hoisting operations. This directive aims to mandate compliance with Aerospatiale’s telex instructions to ensure correct installation and functionality of the hoist equipment, thereby mitigating risks associated with explosive squibs.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the compliance of certain Dauphin series helicopters with Airworthiness Directives (AD). This regulation applies to all Dauphin series helicopters, particularly those identified in the Requirement Document, which are fitted with specific Lucas Air Equipment hoists. These include hoists with part number 76375 across all models and serial numbers, as well as hoists with part number 76378 with serial numbers up to and including 266. The regulation requires adherence to the directive outlined in Aerospatiale Telex No 10275/INF/343/55 dated 23 December 1992, which addresses the potential for incorrect connections of the pyrotechnic squib in the hoist system. To ensure safety, installed hoists must comply with the directive prior to the first hoisting mission following 12 November 1992, but no later than 31 December 1992, while spare hoists must comply prior to installation. This directive is essential to guarantee that the pyrotechnic squib will operate correctly when required. The regulation applies nationwide, ensuring a uniform safety standard across all jurisdictions within the Commonwealth of Australia.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, specifically addresses airworthiness directives related to certain aircraft models, including the Eurocopter SA 360 and SA 365 (Dauphin) series helicopters. This section details the specific requirements and actions that must be taken for Dauphin series helicopters fitted with certain Lucas Air Equipment hoists (section 39-105). The directive, identified as AD/DAUPHIN/33, focuses on the Lucas Air Equipment hoist part number 76375 and part number 76378 with specific serial numbers. These regulations mandate that all Dauphin series helicopters with the specified hoist parts must comply with Aerospatiale Telex No 10275/INF/343/55 dated 23 December 1992, which outlines the necessary actions to ensure the correct installation and functioning of the hoist squib. For installed hoists, this compliance must be achieved before the first hoisting mission following 12 November 1992, but no later than 31 December 1992. For spare hoists, compliance is required before they are installed (section 39-105). The obligations imposed by these regulations are clear and specific. Operators of the affected helicopters must ensure that all installed hoists are checked and, if necessary, modified to meet the directive's requirements before the specified dates. This includes verifying that the pyrotechnic squib is correctly connected to prevent any potential malfunction during operations. Additionally, any new or spare hoists must also be inspected and prepared in accordance with the directive before they are put into service (section 39-105). Failure to comply with the airworthiness directive can result in significant consequences. The Civil Aviation Safety Authority (CASA) can impose penalties for non-compliance, which can include fines and other enforcement actions. The specific penalties are not detailed within the provided text but typically include civil and potentially criminal penalties depending on the severity of the breach and the impact on aviation safety (section 39-105). Ensuring adherence to these directives is critical for maintaining the safety standards required in civil aviation operations.
