AD/CESSNA 177/9 - Fuel Quantity Transmitter

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, is a legislative instrument enacted by the Parliament of the Commonwealth of Australia to ensure the safety and efficiency of civil aviation within Australia. The Act was introduced to address safety concerns and gaps in the regulation of civil aviation operations, aiming to establish a comprehensive regulatory framework that meets international standards and protects the public. This particular legislative instrument pertains to the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives, focusing on the maintenance and operational standards for specific aircraft models. For instance, Airworthiness Directive AD/CESSNA 177/9 targets the fuel quantity transmitter issue in certain Cessna 177 Series Aeroplanes, ensuring compliance with specified maintenance actions and timelines to mitigate potential safety risks. The policy objective underpinning this directive is to mandate specific maintenance actions on affected Cessna 177 Series aeroplanes to ensure continued airworthiness and safety. By referencing relevant service letters and Federal Aviation Administration (FAA) directives, CASA ensures that the maintenance procedures align with recognised standards and practices, thereby enhancing the overall safety of civil aviation within Australia. The directive requires compliance within a specified timeframe, underscoring the importance of timely adherence to safety regulations.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to Airworthiness Directives for aircraft operating within Australia. This legislative instrument applies to particular models of aircraft, in this case, Cessna 177 Series Aeroplanes, identified by specific serial numbers. These serial numbers include ranges from 17700001 to 17701160, 17701165 to 17701168, 17701171, 17701174 to 17701178, and 17701180, ensuring a targeted and precise application. The requirement outlined is for action in accordance with Cessna Service Letter SE69-25, with reference to FAA AD 70-1-2, which indicates a compliance timeline of within 100 hours of time in service following 29 April 1971. This regulation underscores the importance of specific maintenance and operational standards for the specified aircraft models to ensure their airworthiness.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, address airworthiness directives for various aircraft, including the Cessna 177 Series Aeroplanes, under the authority of the Civil Aviation Safety Authority. One such directive, AD/CESSNA 177/9, pertains to the fuel quantity transmitter (Section 4/70). This directive applies to certain models of Cessna 177 and 177A aeroplanes, specifically those with serial numbers (S/Nos.) ranging from 17700001 through 17701160, 17701165 through 17701168, 17701171, 17701174 through 17701178, and 17701180. The directive mandates compliance with Cessna Service Letter No. SE69-25, which is referenced in FAA AD 70-1-2. Operators of the affected aircraft must ensure that the specified maintenance action, as outlined in Cessna Service Letter SE69-25, is performed. This action must be completed within 100 hours of time in service after 29 April 1971. Failure to adhere to this requirement could result in non-compliance with airworthiness standards, potentially affecting the safety and legality of the aircraft operation. Failure to comply with the airworthiness directive AD/CESSNA 177/9 may lead to serious consequences. The Civil Aviation Regulations 1998 impose obligations on aircraft operators to ensure that all specified maintenance and modifications are carried out as required by airworthiness directives. Non-compliance can result in enforcement actions by the Civil Aviation Safety Authority, including the potential for the aircraft to be grounded until the required actions are completed. This could disrupt flight operations and potentially result in financial penalties or other sanctions. Additionally, under the Civil Aviation Act 1988, breaches of the airworthiness requirements can result in both civil and criminal penalties. For civil penalties, operators may face fines, and for criminal penalties, individuals responsible for non-compliance could be prosecuted. The maximum penalties for such breaches are detailed in the Civil Aviation Regulations 1998 and can include substantial fines, imprisonment, or both, depending on the severity of the breach and the circumstances surrounding it. Ensuring adherence to these directives is crucial for maintaining the safety and airworthiness of the affected aircraft.
