AD/BEECH 90/12 - Ammeter Lead Circuit Protection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve to regulate civil aviation safety throughout the country, ensuring the safe operation of aircraft and the protection of persons and property. One significant legislative instrument under this act is AD/BEECH 90/12, which was introduced to address a specific safety concern related to the Beechcraft 90 and 65-90 (King Air) series aeroplanes. This directive was issued by the Civil Aviation Safety Authority to mandate the installation of a suitable circuit protection device in each ammeter lead near the shunts to mitigate electrical faults that could potentially compromise the aircraft's safety. The policy objective behind this directive is to prevent electrical failures that could lead to significant operational risks, thereby enhancing the overall safety of civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, under the authority of the Civil Aviation Safety Authority, encompasses a specific scope within the aviation industry, particularly targeting Beechcraft 90 and 65-90 (King Air) series aeroplanes. This legislation mandates the installation of a suitable circuit protection device in each ammeter lead near the shunts for all models of the specified aircraft. The requirement is to ensure compliance forthwith, highlighting the urgency and importance of this safety measure. This regulation applies across the Commonwealth of Australia, establishing a uniform standard for airworthiness and safety across the aviation sector within the nation. The Civil Aviation Regulations 1998 extend their jurisdictional reach to ensure adherence to the specified airworthiness directive throughout Australia, irrespective of state or territory boundaries. This directive is binding on all operators of Beechcraft 90 and 65-90 series aeroplanes within the country, leaving no room for exemptions or exclusions concerning the installation of circuit protection devices. The regulation may be further elaborated or extended through subordinate instruments, which would provide additional details or specifications necessary for compliance.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, impose a directive on the Beechcraft 90 and 65-90 (King Air) series aeroplanes through the Airworthiness Directive AD/BEECH 90/12, dated 11/67. This directive mandates the installation of a suitable circuit protection device in each ammeter lead near the shunts (Section 1). The directive applies to all models within this series (Section 2). The directive requires immediate action from the operators of these aircraft, mandating that they must install the specified circuit protection devices in accordance with the directive (Section 3). This requirement is intended to ensure the continued safety and airworthiness of the aircraft by preventing potential electrical failures that could lead to hazardous conditions. Operators and owners of Beechcraft 90 and 65-90 series aeroplanes must comply with this directive without delay. They are responsible for ensuring that the specified modifications are carried out by qualified personnel. Non-compliance with this directive may result in the aircraft being deemed unairworthy, which can lead to severe operational restrictions or grounding of the aircraft until the required modifications are completed. Failure to comply with the directive may result in regulatory action against the operators. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can lead to both civil and criminal penalties. Civil penalties can include fines and operational restrictions on the aircraft, while criminal penalties can result in imprisonment for individuals responsible for the non-compliance. The specific penalties are determined by the severity of the breach and the discretion of the court.
