AD/BEECH 90/39 - Pre-Certification Requirements - Mods

Overview

The Civil Aviation Regulations 1998, amended by the Civil Aviation Amendment (Safety and Other Matters) Regulations 2006, aim to ensure the safety of aviation operations in Australia by imposing stringent airworthiness standards and procedures. These regulations were introduced to address the need for a robust framework to oversee and regulate civil aviation safety, encompassing all aspects from aircraft design and maintenance to operational standards. The policy objective behind these regulations is to protect public safety and property by minimising the risks associated with civil aviation, ensuring that all aircraft meet the highest safety standards before and during operation. The regulations are enacted by the Australian Parliament and enforced by the Civil Aviation Safety Authority (CASA), which is tasked with the administration and compliance oversight of these safety directives. One specific example of these regulations in action is found in Part 39 - 105 of the Civil Aviation Regulations, which outlines airworthiness directives for specific aircraft models, such as the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes. This directive, AD/BEECH 90/39, mandates pre-certification modifications to ensure compliance with safety standards, such as installing fuelling equipment bonding points and external earthing points. The directive also requires the installation of a turn and slip indicator power advisory light, with compliance needed before a specified date to ensure the safety and airworthiness of these aircraft. The regulations are designed to be implemented and overseen by CASA, which enforces these standards to maintain the high levels of safety required in Australian civil aviation.

Scope and Application

The Civil Aviation Safety Authority (CASA) has issued Airworthiness Directives (AD) under the Civil Aviation Regulations 1998, specifically in Part 39 - 105. This legislation applies to all operators and owners of Beechcraft 90 and 65-90 (King Air) series aeroplanes, mandating modifications to ensure compliance with safety standards. The directive is applicable nationwide across Australia, reflecting the Commonwealth's jurisdictional reach in regulating civil aviation. The directive stipulates that modifications must be completed by 29 August 1975, and includes specific requirements such as the installation of fuelling equipment bonding points at each fuel filling point, the installation and identification of external earthing points for ground connections, and the incorporation of a turn and slip indicator power advisory light. There are no stated exclusions or exemptions within the directive itself, although the application and enforcement may be subject to variations through subordinate instruments or additional CASA regulations.

Key Provisions

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, detail the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes. One such directive, AD/BEECH 90/39, concerns pre-certification requirements for modifications (Section 8/75). This directive applies to all model E90 aircraft and mandates that they be modified in accordance with the requirements of ANO 101.22. The primary modifications required are 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, either at each main undercarriage assembly or on the nose gear. Additionally, a turn and slip indicator power advisory light must be installed. Compliance with the requirements outlined in AD/BEECH 90/39 is mandatory for all model E90 aircraft. The modifications must be completed before 29 August 1975 to ensure the aircraft meet the safety standards set by CASA. The modifications are intended to enhance safety features, such as proper bonding and grounding of the aircraft’s fuel system, and to provide clear indicators of operational status, such as the power advisory light for the turn and slip indicator. Failure to comply with the provisions of AD/BEECH 90/39 can result in serious consequences. Under Section 205 of the Civil Aviation Act 1988, non-compliance with an Airworthiness Directive can be considered an offence. The penalties for such breaches can be severe and may include fines and imprisonment. Specifically, individuals can face fines of up to $21,000, while corporations can be fined up to $105,000 for each offence. Additionally, CASA has the authority to take action against the aircraft's operator, which can include grounding the aircraft until the required modifications are made, thereby impacting the operator's ability to conduct flights and potentially leading to financial loss and reputational damage. The strict enforcement of these regulations underscores the importance of adhering to safety directives to ensure the continued airworthiness and safety of aircraft. Compliance not only helps in preventing accidents but also maintains the integrity and reliability of the aviation industry, ensuring the safety of passengers, crew, and the general public.
