AD/CESSNA 206/17 - Pre-Certification Requirements

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, addressing the safety standards and compliance requirements for aircraft operating within Australia. The enactment of these regulations by the Parliament of Australia aims to ensure that all civil aircraft meet stringent safety and operational standards to protect passengers, crew, and the public. The policy objective of these regulations is to mitigate risks associated with aircraft operations by mandating specific modifications and installations, such as placards prohibiting smoking in the cabin, bonding points for fuelling equipment, and grounding points for the aircraft's electrical systems. These measures are critical in preventing accidents and ensuring the integrity of the aircraft's fuel system, thereby enhancing overall aviation safety. The Civil Aviation Regulations 1998 were introduced to address the need for a comprehensive and enforceable framework governing the safety and operational standards of civil aircraft. By specifying pre-certification requirements for particular aircraft models, such as the Cessna 206 Series Aeroplanes, the regulations ensure that all aircraft meet essential safety standards before they are certified for operation. The inclusion of directives for installing placards, bonding and grounding points, and fire-resistant hose assemblies reflects the intent to prevent potential hazards and ensure the continued airworthiness of the aircraft. The Civil Aviation Safety Authority enforces these directives to uphold the highest safety standards within the Australian civil aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to airworthiness directives issued by the Civil Aviation Safety Authority (CASA) and apply to the Cessna 206 Series Aeroplanes, particularly the Model U206F. This legislation mandates that aircraft modifications must be made in accordance with the Australian National Standards (ANO) and other specified requirements to ensure safety standards are met before a Certificate of Airworthiness is issued. The directives require the installation of placards prohibiting smoking in the cabin, the identification and installation of bonding and earthing points for fuel systems, and the replacement or modification of certain hose assemblies to meet stringent fire resistance standards. These provisions are integral to ensuring the operational safety of the aircraft within Australian airspace. The geographic reach of this legislation is national, as it applies to all Cessna 206 Series Aeroplanes operating within Australia and subject to CASA's regulatory oversight. The regulations do not explicitly state exclusions or exemptions, but compliance is mandatory for all affected aircraft. The application of these directives may be extended or clarified through subordinate instruments or additional CASA guidelines, ensuring that all operational and safety requirements are met comprehensively.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, mandate certain pre-certification requirements for Cessna 206 Series Aeroplanes (Section 1/75). The primary requirement under AD/CESSNA 206/17 is to modify the aircraft to ensure compliance with ANO 101-22. Firstly, a placard must be installed in the cabin, clearly indicating the periods during which smoking is prohibited (Section 1). Secondly, the aircraft must have fuelling equipment bonding points at each fuel filling point and external earthing points for ground connections on each main undercarriage assembly or the nose gear (Section 2). Thirdly, the specified flexible hose assemblies must either be replaced or rendered fire-resistant to FAA TSO C53B Type C or D standards (Section 3). These modifications are mandatory before a Certificate of Airworthiness can be issued. The installation of the smoking placard, the bonding points, and the earthing points are straightforward, requiring clear identification and placement according to the regulations. For the hose assemblies, the regulation allows for either replacement with assemblies that meet the specified fire resistance standards or the fitting of approved fire sleeves to achieve the same level of fire resistance. Failure to comply with these requirements can lead to significant consequences. The most direct consequence is the non-issuance of a Certificate of Airworthiness, which is a critical document for the legal operation of the aircraft. Additionally, operating an aircraft that does not comply with these safety directives may result in enforcement actions by the Civil Aviation Safety Authority (CASA). In severe cases, CASA can impose fines or other penalties as stipulated in the Civil Aviation Act 1988, which may include substantial monetary penalties or legal action against the aircraft owner or operator. It is essential for all parties involved in the certification process to adhere strictly to these regulations to avoid any legal repercussions or safety hazards.
