AD/BEECH 23/33 - Fuel Selector Valve

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, encompass a wide range of regulations designed to ensure the safety and efficiency of civil aviation within Australia. One particular aspect of these regulations is the issuance of Airworthiness Directives (ADs), which are specific to ensuring that aircraft meet certain safety standards. The ADs are published by the Civil Aviation Safety Authority (CASA) under the authority granted by the Civil Aviation Act 1988. The objective of these directives is to address identified safety issues and ensure that all aircraft operating within Australia adhere to the highest safety standards. For example, AD/BEECH 23/33 pertains to the fuel selector valves of certain Beechcraft aeroplanes, aiming to enhance safety by replacing and inspecting components that could potentially affect fuel management and flight safety. This particular legislative instrument, F2006B03747, focuses on the Beechcraft 19, 23, and 24 series aeroplanes, mandating the replacement and inspection of the fuel selector guard, and ensuring the correct placarding and functionality of the fuel selector valve. This directive was introduced to address specific safety concerns related to fuel management in these aircraft models, ensuring that these aeroplanes maintain their airworthiness and continue to meet the stringent safety standards set forth by CASA. The requirement to comply with this directive within specified time intervals is intended to proactively address potential safety risks and maintain operational safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes Airworthiness Directives (AD) that apply to particular types of aircraft to ensure safety standards are maintained. This particular legislative instrument pertains to the Beechcraft 19, 23, and 24 series aeroplanes, detailing mandatory requirements for the fuel selector valve. The directive applies to specific models and serial numbers of these aircraft, ensuring that they meet certain safety benchmarks. Compliance with these requirements is mandatory for the specified aircraft, and the regulations outline specific time intervals and conditions for inspections and replacements, ensuring that these aircraft remain airworthy and safe for operation. This directive forms part of the broader regulatory framework overseen by the Civil Aviation Safety Authority (CASA), which governs the safety and maintenance standards for civil aviation in Australia. The geographic reach of these regulations is national, applying across all states and territories within Australia, and they extend to any aircraft registered in Australia that meets the specified model and serial number criteria. While the primary focus is on ensuring the safety of the specified aircraft, there are no stated exclusions or exemptions to the application of these regulations. Compliance is enforced through CASA, which has the authority to conduct inspections, audits, and take enforcement actions as necessary to ensure adherence to the specified safety directives. Additionally, CASA may issue further subordinate instruments or guidance to clarify or expand on the application of these directives, ensuring that safety standards are consistently applied and maintained.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Section 105, outlines a schedule of airworthiness directives for various aircraft models, including Beechcraft 19, 23, and 24 series aeroplanes. One such directive is AD/BEECH 23/33, which pertains to the fuel selector valve of these aircraft models (AD/BEECH 23/33). This directive applies to specific serial numbers of the Beechcraft A23-19, 19A, M19A, B19, A23, A23A, B23, C23, A23-24, A24, A24R, and B24R models (AD/BEECH 23/33). The directive sets out three primary requirements. First, if the fuel selector guard has not already been installed under Beechcraft SI No. 0364-289 Rev 3, it must be replaced with a new guard as detailed in Beechcraft SI No. 0838 (AD/BEECH 23/33). Second, the fuel selector guard must be inspected to ensure that it displays the correct placard indicating the unusable fuel quantity, as per Beechcraft SI No. 0838 (AD/BEECH 23/33). Third, the guard must be checked for freedom from binding and for the correct shut-off of the fuel selector valve, following Beechcraft SI No. 0364-289 Revision 3 (AD/BEECH 23/33). It is important to note that paragraph 3 does not apply to aircraft equipped with a P/N 169-380086-1 fuel selector valve (AD/BEECH 23/33). Aircraft owners and operators must ensure compliance with these requirements. Specifically, paragraphs 1 and 2 of the directive must be adhered to within 100 hours of time in service after 31 August 1977. For paragraph 3, compliance must be achieved within 100 hours of time in service after 31 August 1977 and then at intervals not exceeding 100 hours of time in service (AD/BEECH 23/33). Failure to comply with the requirements of AD/BEECH 23/33 could result in civil or criminal consequences. Under the Civil Aviation Act 1988, non-compliance may lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The specific penalties for breaching these regulations can include fines and potential imprisonment, depending on the severity of the non-compliance and any resultant safety risks. The maximum penalties are determined by the courts and can vary based on the specific circumstances of each case.
