Overview

The Airworthiness Directive AD/ECUREUIL/92, issued in 2003, addresses a safety concern identified with specific modifications made to Eurocopter AS 350 (Ecureuil) Series Helicopters by Mann Aviation Group (Engineering) Ltd (MAG(E)). The directive was enacted by the Civil Aviation Safety Authority (CASA), which operates under the oversight of the Australian Government, to ensure the safety of air operations by mandating specific actions to correct an unsafe condition. The directive was introduced to rectify the inadequate clearance between the mounting panels of the camera system and the primary controls of the helicopters, which could potentially lead to operational hazards such as restriction or jamming of the pedals or cyclic control. The directive requires the inspection and subsequent modification or removal of certain panels to ensure continued compliance with safety standards and to mitigate the identified risk.

Scope and Application

The Airworthiness Directive issued under subregulation 39.1 (1) of the Civil Aviation Safety Regulations 1998 (CASR 1998) pertains to specific models of Eurocopter AS 350 (Ecureuil) Series Helicopters that have undergone modifications as per Mann Aviation Group (Engineering) Ltd (MAG(E)) modifications 350-1521 or 350-1680, and the installation of a camera system. The directive applies to all such aircraft that fall under the mentioned modifications and installations. The primary aim is to address an identified safety issue concerning inadequate clearance between mounting panel cut-outs and primary controls, which could potentially result in restricted or jammed pedals or cyclic control. The directive is effective throughout the Commonwealth of Australia, with compliance mandated before further flight after 1 October 2003, before next installation or within 30 days after 1 October 2003, and within 30 days after 1 October 2003 for panels already inspected and found non-compliant. This AD does not explicitly state any exclusions or exemptions, suggesting that all applicable helicopters must adhere to the requirements set forth. The application and compliance timelines are clearly defined, and the directive is expected to be enforced by relevant authorities within the jurisdiction of the Civil Aviation Safety Authority (CASA).

Key Provisions

The Airworthiness Directive (AD) issued under subregulation 39.1(1) of the Civil Aviation Safety Regulations 1998 (CASR) mandates specific actions to address an unsafe condition identified in Eurocopter AS 350 (Ecureuil) series helicopters. These actions are outlined in the requirement section of the directive, which pertains to helicopters that have been modified in accordance with Mann Aviation Group (Engineering) Ltd (MAG(E)) modifications 350-1521 or 350-1680 and the installation of a camera system. The directive applies to AS 350 helicopters that have undergone the aforementioned modifications and installed the camera platform. It requires the inspection and modification of certain panels within the specified timeframes to ensure compliance with safety standards. The obligations imposed by this AD are precise and mandatory. Owners and operators of affected helicopters must inspect the installed MAG(E) modifications and ensure that any platform panels bearing part number 350-1521-103 that do not meet the specified clearance requirements are removed from service immediately. Additionally, any panels with part number 350-1521-103, whether held in store or removed, must be modified according to the instructions provided in paragraph 2 of MAG(E) SB-A25-001. For panels that have remained installed, the modifications must be completed within the specified timeframes outlined in the compliance section. These obligations ensure that the identified safety issue is addressed promptly and effectively. Failure to comply with the AD can result in significant legal and operational consequences. The AD sets specific deadlines for compliance, which must be met to avoid any adverse actions. The maximum penalties for non-compliance with ADs are set out in the Civil Aviation Act 1988 and the Civil Aviation Regulations 1988. Violations can lead to substantial fines, with the exact penalties determined by the severity of the breach. In the most serious cases, non-compliance can result in criminal charges, leading to imprisonment. Additionally, aircraft found to be non-compliant can be grounded until the required modifications are completed, which can severely impact operational capabilities and lead to further financial losses.
