Overview

The Civil Aviation Regulations 1998 (CAR 1998), enacted in 1998, were established to regulate civil aviation safety in Australia, ensuring that aircraft and aeronautical products meet specific safety standards. This legislation is overseen by the Civil Aviation Safety Authority (CASA) and is instrumental in addressing safety issues and gaps within the aviation industry. In particular, it provides a legal framework for issuing Airworthiness Directives (ADs) to rectify identified safety concerns. One such AD is AD/A119/4 issued in May 2002, which specifically addresses the problem of hydraulic fluid leakage in Agusta A119 Series helicopters. The policy objective of this AD is to mitigate the risk of hydraulic fluid contamination of the transmission, which could otherwise necessitate the removal of the main transmission. This directive mandates regular checks of hydraulic fluid levels and the replacement of the hydraulic pump to prevent unsafe conditions.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to all Agusta A119 series helicopters equipped with a particular hydraulic pump, identified by part number 109-076-42-101. This directive is issued by a delegate of the Civil Aviation Safety Authority (CASA) and mandates specific actions to address identified unsafe conditions related to the hydraulic system of these helicopters. The requirements include regular checks of hydraulic fluid levels, analysis for contamination in the transmission fluid, and the replacement of the hydraulic pump. The directive also specifies that contaminated transmissions must be removed before further flights, as detailed in Agusta Technical Bulletin 119-4. Compliance with these directives must occur at specified intervals and deadlines, with the directive becoming effective from 16 May 2002. This legislation extends to the Commonwealth of Australia, ensuring that all relevant aircraft within its jurisdiction adhere to these safety standards to prevent potential hazards arising from hydraulic fluid contamination.

Key Provisions

The main operative sections of this Airworthiness Directive (AD) for Agusta A119 Series Helicopters, as detailed in the Civil Aviation Regulations 1998, involve specific actions and compliance schedules (sections 1 and 2). Section 1 of the AD mandates a series of checks and actions, such as inspecting the hydraulic fluid level and conducting an analysis if excessive consumption is detected, without signs of external leakage. If contamination of the transmission by hydraulic fluid is found, the transmission must be removed before any further flight in accordance with Agusta Technical Bulletin 119-4. Section 2 of the AD requires the replacement of the hydraulic pump, noting the reference to Italian AD 2002-113. Compliance with these requirements is scheduled such that the checks outlined in section 1 must occur at each daily inspection, while the pump replacement stipulated in section 2 must be completed before 31st December 2002. The obligations and requirements imposed by this AD on the parties it governs are quite specific. Operators and owners of Agusta A119 helicopters must ensure that their aircraft comply with the directive’s stipulations. This includes conducting daily inspections to check the hydraulic fluid level and performing analyses if necessary, as well as ensuring that any contaminated transmissions are removed and that the hydraulic pump is replaced by the specified date. These actions must be carried out strictly in accordance with the instructions provided in Agusta Technical Bulletin 119-4 and the Italian AD 2002-113. Non-compliance with these directives could potentially result in unsafe conditions, thereby affecting the airworthiness and operational safety of the aircraft. Failure to adhere to the provisions outlined in this AD may lead to serious civil and criminal consequences. The AD is designed to ensure that certain safety measures are taken to prevent unsafe conditions, and any breach of these requirements could result in significant penalties. While the specific penalties are not detailed in the AD itself, non-compliance with Civil Aviation Regulations can generally lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions may include fines, operational restrictions, or even the grounding of non-compliant aircraft. The severity of the penalties may depend on the nature and extent of the non-compliance, with potential maximum penalties varying based on the specific regulations and the discretion of the enforcement authority.
