AD/GAZELLE/19 - SAMM Main Servo Controls

Overview

The Civil Aviation Regulations 1998 (Cth), specifically Part 39 - 105, address the critical issue of ensuring airworthiness in civil aviation by providing detailed directives and requirements for aircraft maintenance. Enacted by the Commonwealth of Australia, this legislation was introduced to ensure the safety and reliability of aircraft in operation by providing clear guidelines and mandatory directives, particularly for maintaining specific models such as the Eurocopter SA341 and SA342 (Gazelle) Series Helicopters. The objective of these regulations is to mitigate risks associated with aircraft components, ensuring they meet the stringent safety standards necessary to protect passengers, crew, and the general public. This legislative instrument, AD/GAZELLE/19, focuses on the SAMM Main Servo Controls for the specified helicopter models, aiming to address potential manufacturing defects that could compromise safety. By mandating compliance with specific service bulletins and directives, such as Eurocopter SA 341/342 Mandatory SB No 05.31, the Civil Aviation Regulations 1998 provide a robust framework to ensure that any identified issues are promptly and effectively addressed, thereby upholding the highest standards of aviation safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the safety directives applicable to the Eurocopter SA341 and SA342 (Gazelle) series helicopters, targeting aircraft with the SAMM Main Servo Control SC-5041-A1 (704A44-831-042) installed. The regulation mandates compliance with Eurocopter SA 341/342 Mandatory Service Bulletin No 05.31, which was issued following concerns about potential incorrect torque settings during the assembly of the servo control rod. This directive applies nationally across Australia and is overseen by the Civil Aviation Safety Authority (CASA). The requirement necessitates adherence to the specific actions outlined in the referenced service bulletin, with a compliance deadline set for 14 October 1994. The regulation ensures that all affected helicopters meet the safety standards stipulated by CASA, thereby mitigating potential risks associated with the identified assembly issue.

Key Provisions

The key operative sections of the Civil Aviation Regulations 1998, specifically within Part 39 - 105 and the Airworthiness Directives for Eurocopter SA341 and SA342 (Gazelle) Series Helicopters, focus on ensuring the airworthiness of helicopters with specific components. Section AD/GAZELLE/19 pertains to the SAMM Main Servo Controls, more precisely the SC-5041-A1 (704A44-831-042). This directive mandates that all model SA 341/342 helicopters equipped with this particular servo control must adhere to the actions outlined in Eurocopter SA 341/342 Mandatory Service Bulletin No 05.31. This requirement is to address a potential issue where the servo control rod may have been incorrectly torqued during assembly, as noted by the manufacturer. The directive references DGAC AD 94-194-037(B) and specifies compliance with the requirement document, effective from 14 October 1994. The obligations imposed by this directive on the relevant parties, including helicopter operators and maintenance organisations, are to follow the mandatory actions detailed in Service Bulletin No 05.31. This includes inspecting and, if necessary, rectifying the torque of the servo control rod to ensure it meets the manufacturer's specifications. The directive mandates that these actions be undertaken to prevent any potential operational risks associated with incorrectly torqued components, ensuring the continued safety and airworthiness of the aircraft. Operators and maintenance personnel must document compliance with these directives, providing evidence that the required actions have been completed and verified. Failure to comply with the provisions of this Airworthiness Directive may result in significant consequences. Under the Civil Aviation Act 1988, non-compliance can be considered an offence. The potential penalties for such breaches include fines and, in severe cases, criminal charges. The specific maximum penalties are not detailed within this directive but are generally outlined under the broader regulatory framework governing civil aviation in Australia. These penalties underscore the importance of adhering to airworthiness directives to maintain the safety and compliance of aircraft operations.
