AD/AC/57 - Pre-Certification Requirements - Modifications

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, provide a comprehensive framework for ensuring the safety and efficiency of civil aviation in the country. Specifically, Part 39 of these regulations addresses the issue of airworthiness directives, which are legally enforceable rules that aim to ensure that aircraft remain safe to fly. These directives are crucial in maintaining the integrity of the aviation system by mandating specific modifications or actions to address identified safety concerns. The legislative instrument F2006B02116, which pertains to the Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600, and 700) series aeroplanes, highlights the importance of pre-certification requirements and modifications to meet the stringent safety standards set by the Civil Aviation Safety Authority. This particular directive aims to ensure that fuel systems and grounding points are properly installed and identified, thereby mitigating risks associated with fuel handling and static electricity. The policy objective is to enhance the overall safety and operational reliability of the specified aircraft models by enforcing these critical modifications.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105 concerning Civil Aviation Safety Authority Schedule of Airworthiness Directives for Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600, and 700) Series Aeroplanes, applies to all models 690 and 690A. This legislation mandates specific modifications to the aircraft to ensure compliance with aviation safety standards, particularly in relation to pre-certification requirements. It necessitates the installation of fuelling equipment bonding points at each fuel filling point and the installation and identification of external earthing points on each main undercarriage assembly or on the nose gear. Compliance with these directives must be achieved before 31 March 1975, ensuring that all affected aircraft meet the necessary safety criteria set forth by the Civil Aviation Safety Authority. The scope of this regulation extends to all relevant aircraft models within the specified series and is enforced under the jurisdiction of the Commonwealth of Australia. There are no exclusions or exemptions mentioned within the text, implying that all affected aircraft must adhere to the requirements. The regulations are enforced through the Civil Aviation Safety Authority, and any further clarification or extension of application may be detailed in subordinate instruments or additional directives issued by the authority.

Key Provisions

The Civil Aviation Regulations 1998, particularly under Part 39 - 105, address the airworthiness directives for specific aircraft models. In this case, the focus is on the Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600, and 700) Series Aeroplanes, with the directive AD/AC/57 outlining pre-certification requirements for modifications (AD/AC/57). This directive applies to all models 690 and 690A. The main requirement stipulated in section 2 of the directive is that aircraft must be modified to comply with ANO 101.22. Specifically, these modifications include the installation of fuelling equipment bonding points at each fuel filling point and the installation and identification of external earthing points, for the attachment of ground connections, on each main undercarriage assembly or on the nose gear. The obligations imposed by this directive are clear and direct. Aircraft operators and owners must ensure that the modifications outlined in section 2 are carried out on the specified models, 690 and 690A. These modifications are intended to enhance the safety and functionality of the aircraft by improving the integrity of the electrical systems related to fuelling and grounding. Compliance with these requirements is mandatory, with a deadline of 31 March 1975 set for the completion of the modifications. Failure to comply with the airworthiness directives can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives can lead to civil and criminal penalties. Civil penalties may include fines, while criminal penalties could result in imprisonment, reflecting the seriousness of ensuring that aircraft meet the required safety standards. The specific maximum penalties are not detailed in the excerpt provided, but they are significant, underscoring the importance of adhering to the directives to maintain the safety of air travel.
