Overview

The Civil Aviation Safety Regulations 1998, specifically under Part 39 - 105, introduced Airworthiness Directives to ensure the ongoing airworthiness of civil aircraft and aeronautical products in Australia. Enacted by the Commonwealth of Australia, this legislation was introduced to address safety concerns identified by the Civil Aviation Safety Authority (CASA). The purpose of the Airworthiness Directives is to mandate corrective actions to mitigate identified safety risks, ensuring the continued safe operation of aircraft within Australia's airspace. In this instance, the Airworthiness Directive AD/S-PUMA/48, issued on 5 May 2003, specifically targets the hydraulic reservoir fittings of Eurocopter AS 332 (Super Puma) Series Helicopters delivered before 1 January 2003, to address the risk of hydraulic system failure due to cracking of certain hydraulic adaptors.

Scope and Application

The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, outlines the requirements and procedures for airworthiness directives issued by the Civil Aviation Safety Authority (CASA). This legislative instrument applies to Eurocopter AS 332 (Super Puma) series helicopters, namely versions C, C1, L, and L1, that were delivered by the manufacturer before 1 January 2003. The directive mandates that these aircraft must comply with specific requirements to address a known safety issue concerning hydraulic reservoir fittings. The identified unsafe condition involves hydraulic adapters that are prone to cracking, which can lead to system failure and loss of hydraulic power assistance to the flight controls. The directive requires operators to identify and, if necessary, replace certain hydraulic adapters in accordance with detailed instructions provided in Eurocopter Alert Service Bulletin (ASB) 67.00.25. Compliance with the AD is mandatory, with specific timelines set for the identification and replacement of the hydraulic adapters, and must be completed before further flight following the identification of the hydraulic adapter fitting. The AD is effective from 15 May 2003 and was gazetted on 23 April 2003.

Key Provisions

The Airworthiness Directive (AD) AD/S-PUMA/48 issued under subregulation 39.1 (1) of the Civil Aviation Safety Regulations 1998 (CASR 1998) targets specific versions of the Eurocopter AS 332 (Super Puma) helicopters, namely versions C, C1, L and L1 that were delivered before 1 January 2003. The directive mandates that these helicopters must have their hydraulic adapter fittings inspected and, if necessary, replaced. This is to address an identified safety issue related to the potential cracking of certain hydraulic adaptors, which could lead to a failure in the hydraulic system and consequently result in the loss of hydraulic power assistance to the flight controls. The directive requires that the hydraulic adapter fitted to the right-hand hydraulic reservoir be identified according to the instructions in Paragraph 2.B.1 through 2.B.3 of Eurocopter Alert Service Bulletin (ASB) 67.00.25. Any adapter identified in Paragraph 2.B.2 of ASB 67.00.25 must be replaced following the instructions in Paragraph 2.B.4 of the same bulletin. Notably, the replacement pertains specifically to those hydraulic fittings manufactured before the year 2002 and not marked with a yellow paint mark. The directive sets a compliance timeline, mandating that the identification of the hydraulic adapter must occur within 30 days from the effective date of the directive, which is 15 May 2003, and before the installation of the hydraulic adapter in an aircraft. Additionally, the replacement must be completed before any further flight following the identification of the hydraulic adapter fitting. Compliance with this Airworthiness Directive is mandatory for the specified Eurocopter AS 332 helicopters. Operators of these aircraft must ensure that the required inspections and replacements are carried out by certified personnel within the stipulated timeframes to maintain the airworthiness of their aircraft. Failure to comply with this directive could result in significant safety risks, as the potential cracking of the hydraulic adaptors could lead to hydraulic system failure and the consequential loss of critical flight controls. The AD does not explicitly state penalties for non-compliance, but non-compliance with ADs under the CASR 1998 can lead to severe consequences. These can include civil penalties, such as fines, and criminal penalties, including imprisonment, for those responsible for the aircraft or its operations. The severity of the penalties reflects the critical nature of ensuring aircraft airworthiness to maintain public safety in the aviation industry.
