AD/CESSNA 177/24 - Fuel Quantity Transmitter

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, serve as a comprehensive regulatory framework for ensuring the safety and efficiency of civil aviation within the country. Within this framework, Part 39, which pertains to airworthiness directives, addresses specific safety concerns and operational requirements for various aircraft types. One such directive is AD/CESSNA 177/24, focusing on the fuel quantity transmitter for Cessna 177 Series Aeroplanes. This directive was introduced to address potential safety issues associated with fuel quantity transmitters in certain models of Cessna 177 aeroplanes, specifically those with serial numbers within a defined range. The policy objective is to ensure compliance with manufacturer service letters and specifications, thereby enhancing the safety and reliability of these aircraft in operation. The directive mandates corrective actions within a specified timeframe to rectify identified issues, reflecting the regulatory commitment to maintaining high safety standards in civil aviation.

Scope and Application

The Civil Aviation Safety Authority's regulations, as outlined in the Civil Aviation Regulations 1998, apply to all models of Cessna 177 and 177RG aeroplanes, specifically those with serial numbers ranging from 17700001 to 17702672, 177RG001 to 177RG1266, and F177RG0001 to F177RG0177. This legislative instrument pertains to ensuring the airworthiness of these aircraft, focusing on the fuel quantity transmitter as specified in the Airworthiness Directive (AD) for the Cessna 177 series. Compliance with this directive is mandatory for the specified aircraft within 100 hours of their time in service after 28 February 1979, aligning with the requirements outlined in Cessna Service Letter SE78-69. The regulations are applicable across the Commonwealth of Australia and are enforced to maintain safety standards in civil aviation.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, include detailed requirements for the maintenance and operation of certain aircraft models. For instance, AD/CESSNA 177/24 pertains to the Cessna 177 Series Aeroplanes, focusing on the fuel quantity transmitter (Section 3/79). This directive applies to all models 177 and 177RG with specific serial numbers, ranging from 17700001 to 17702672 for model 177, and 177RG001 to 177RG1266 for model 177RG, along with F177RG0001 to F177RG0177 for model F177RG. The directive mandates compliance with Cessna Service Letter SE78-69, which outlines specific actions that must be taken to ensure the fuel quantity transmitter operates correctly. Operators of these aircraft must implement these actions within 100 hours of time in service following 28 February 1979. This requirement ensures that the fuel quantity transmitter, a critical component for monitoring fuel levels, is functioning as intended, thus maintaining the safety and airworthiness of the aircraft. Entities governed by these regulations must adhere to the outlined compliance timeframe and ensure that the necessary actions are taken without delay. This involves thorough inspection, maintenance, or replacement of the fuel quantity transmitter as specified by Cessna’s service letter. Failure to comply with these directives can result in the aircraft being deemed unairworthy, which could lead to grounding and potential legal consequences. Under the Civil Aviation Regulations, non-compliance with Airworthiness Directives can lead to significant penalties. The Civil Aviation Act 1988 stipulates that operators who fail to adhere to CASA directives may face enforcement actions, including fines and potential prosecution. The severity of these penalties depends on the nature and extent of the non-compliance, with maximum penalties including substantial financial penalties and imprisonment for serious breaches that endanger safety. It is imperative for operators to ensure strict adherence to these directives to avoid these severe consequences.
