Overview
The Civil Aviation Regulations 1998, enacted by the Australian Parliament, are a comprehensive set of rules governing civil aviation within Australia. Among these regulations is Part 39 - 105, which pertains to airworthiness directives, specifically addressing the safety of aircraft operations. One such directive, AD/CESSNA 180/43, focuses on the installation of fuel quantity placards for Cessna 180, 182, and Wren 460 series aeroplanes. This directive aims to enhance flight safety by ensuring pilots have clear and accurate information regarding fuel quantities, thereby reducing the risk of fuel-related incidents. The policy objective is to mandate compliance with specific safety standards set by the Civil Aviation Safety Authority, ensuring the continued airworthiness of these aircraft types.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives concerning Cessna 180, 182 and Wren 460 series aeroplanes. This regulation applies to specific model numbers of Cessna aircraft, requiring the installation of fuel quantity placards as detailed in Cessna Service Letter SE75-7 and Supplement No. 1. The applicability of this directive is determined by the aircraft's serial numbers and the installation of particular fuel cells. Compliance with the directive varies depending on the serial number range of the aircraft and whether the specified fuel cells have already been installed or are being installed concurrently. The geographic reach of this regulation is national, as it is a Commonwealth regulation under Australian law. There are no stated exclusions, exemptions, or thresholds in the provided text, and the application of this directive is directly governed by the conditions specified without extension or restriction through subordinate instruments.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105 (Regulations) detail the Airworthiness Directives (AD) applicable to the Cessna 180, 182, and Wren 460 Series Aeroplanes. Specifically, AD/CESSNA 180/43 pertains to the installation of fuel quantity placards, as outlined in Cessna SL SE75-7 and Supplement No. 1. This directive is crucial for ensuring the safety and airworthiness of these aircraft models, especially in relation to fuel management and pilot awareness.
The main sections of the AD require the installation of fuel quantity placards for specific Cessna 180 and 182 models. For Cessna 180 aircraft, the requirement is to install the placards within 100 hours of time in service after 16 April 1976. However, for Model 180 with serial numbers prior to 52364, the directive specifies two scenarios: if the aircraft is currently fitted with replacement fuel cells manufactured after June 1973, the placards must be installed within 100 hours of time in service after 16 April 1976; otherwise, the placards must be installed concurrently with the fitting of such replacement fuel cells. For Cessna 182 aircraft, the installation of placards must occur within 100 hours of time in service after 31 March 1976 for specified serial numbers. Similar to the Cessna 180, if Model 182 with serial numbers prior to 62251 is equipped with replacement fuel cells manufactured after June 1973, the placards must be installed within 100 hours of time in service after 31 March 1976; if not, they must be installed concurrently with the fitting of such replacement fuel cells.
The AD imposes clear obligations on the parties responsible for maintaining these aircraft. Operators and owners must ensure compliance with the specified timelines for the installation of fuel quantity placards. This involves either installing the placards within the prescribed time frame after the date mentioned in the directive or concurrently with the installation of certain fuel cells. Failure to comply with these requirements could result in the aircraft being considered non-airworthy, thereby preventing it from being operated until the necessary compliance measures are undertaken.
Breach of the requirements set forth in this AD may lead to civil or criminal consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce compliance and may impose penalties for non-compliance. While the specific penalties are not detailed in the text, they may include fines, suspension of the aircraft's airworthiness certificate, or other regulatory actions deemed appropriate by CASA. These measures are intended to ensure that the safety and operational standards are maintained, thereby safeguarding the interests of the aviation community.
