AD/CHA/13 - Stall Warning Horn

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, address various aspects of aviation safety, including the issuance of airworthiness directives to ensure the safe operation of aircraft. One such directive, AD/CHA/13, pertains to the installation of an approved stall warning horn system in American Champion (Aeronca, Bellanca) Series Aeroplanes, specifically models 7EC, 7FC, 7ECA, 7GCAA, 7GCBC, and 7KCAB. The directive was introduced to mitigate the risk of accidents due to in-flight stalls by providing pilots with an audible warning when the aircraft approaches a stall condition. Compliance with this directive is mandatory, with a specified deadline of 31 January 1976, ensuring that the required safety measures are implemented across the affected aircraft fleet to enhance overall aviation safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Civil Aviation Safety Authority's schedule of airworthiness directives which include AD/CHA/13 concerning the installation of a stall warning horn system for American Champion (Aeronca, Bellanca) series aeroplanes. This legislation applies to particular models of American Champion aeroplanes, including 7EC, 7FC, 7ECA, 7GCAA, 7GCBC, and 7KCAB. The directive mandates the installation of an approved stall warning horn system to enhance flight safety and prevent accidents arising from in-flight stalls. Compliance with this directive must be achieved before 31 January 1976, as stipulated by the regulations. The approved stall warning horn systems are detailed in Bellanca-Champion drawings, specifically Dwg. No. 7-1065 for models 7EC and 7FC, and Dwg. No. 7-1401 for models 7ECA, 7GCAA, 7GCBC, and 7KCAB. The regulations apply nationally within Australia, governed by the Commonwealth of Australia, and there are no stated exclusions or exemptions within the provided text, though the application might be subject to further stipulations or amendments through subordinate instruments.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105 under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, sets out the requirements for ensuring the safety of certain American Champion (Aeronca, Bellanca) series aeroplanes. One such directive, AD/CHA/13, pertains to the installation of an approved stall warning horn (s. 39 - 105). This directive applies to models 7EC, 7FC, 7ECA, 7GCAA, 7GCBC, and 7KCAB. The primary requirement (s. 39 - 105) is that an approved stall warning horn system must be installed in these aeroplanes to alert pilots of an impending stall condition, thus enhancing flight safety. Under this legislation, the entities governed, such as aircraft owners, operators, and maintenance providers, have specific obligations to ensure compliance with the Airworthiness Directives. For the American Champion series aeroplanes covered by AD/CHA/13, the requirement is to install an approved stall warning horn system as specified in the directive. This entails adhering to the technical specifications detailed in the referenced Bellanca-Champion drawings, such as Dwg. No. 7-1065 for models 7EC and 7FC, or Dwg. No. 7-1401 for models 7ECA, 7GCAA, 7GCBC, and 7KCAB (s. 39 - 105). The installation must be completed before the specified compliance date of 31 January 1976. Failure to comply with the requirements set out in the Airworthiness Directives can result in serious consequences. The legislation imposes both civil and potential criminal penalties for non-compliance. Civil penalties may include fines, and in more severe cases, criminal penalties could be applicable, including imprisonment. The exact nature and severity of these penalties depend on the specific breach and the discretion of the court. It is essential for all parties involved to adhere to the stipulated requirements to avoid such legal repercussions.
