AD/CESSNA 207/15 - Fuel Reservoir Fitting

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, provide a comprehensive framework for the regulation of civil aviation within Australia. Among these regulations, Part 39 specifically addresses airworthiness directives, which are mandatory requirements for the continued airworthiness of aircraft. The legislative instrument F2006B05274, concerning the Cessna 207 Series Aeroplanes, was introduced to address specific safety concerns related to the fuel reservoir fittings of certain models. The enacting body is the Civil Aviation Safety Authority, which is responsible for enforcing and regulating civil aviation safety standards. The policy objective is to ensure the continued safety of aircraft by mandating specific inspections and repairs as necessary, thereby mitigating risks associated with fuel reservoir integrity. This particular airworthiness directive, AD/CESSNA 207/15, targets models T207 with specific serial numbers, requiring the inspection of the fuel reservoir upper fitting to ensure it meets the specified inside diameter criteria. The directive mandates compliance within 100 hours of time in service following the directive's issuance date of 31 May 1978, ensuring that any identified issues are promptly addressed to maintain the safety and airworthiness of the affected aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, address the issuance of airworthiness directives for maintaining the safety standards of aircraft operating within Australia. This regulation applies to the Cessna 207 Series Aeroplanes, targeting specific serial numbers, namely Model T207 with serial numbers ranging from 20700315 to 20700392, as well as those models with serial numbers below 20700315 that have undergone a replacement of their fuel reservoir assembly with a component originating from Cessna since 1 July 1975. The directive mandates that the fuel reservoir upper fitting must be inspected for the correct inside diameter, following the specifications outlined in Figure 1 of Cessna Service Letter SE77-38, with additional attention to Cessna Service Letter SE78-2. Compliance with this directive is required within 100 hours of the aircraft being in service after 31 May 1978, ensuring the continued safety and airworthiness of these aircraft within the Australian jurisdiction. This legislation falls under the Commonwealth of Australia's regulatory framework, ensuring that the specified Cessna 207 Series Aeroplanes meet the necessary safety standards. The directive applies to specific aircraft models based on their serial numbers and modification history, indicating a targeted approach to addressing potential safety issues. The directive's compliance timeframe is clearly defined, underscoring the importance of timely inspections to maintain airworthiness. The application of this directive is limited to the specified models and serial numbers, with no broader exemptions or exclusions mentioned within the scope of the provided text.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, provides detailed requirements for maintaining the airworthiness of aircraft, with a particular focus on the Cessna 207 Series Aeroplanes. The legislation establishes Airworthiness Directives (ADs) to ensure that specific aircraft models meet safety standards. One such AD, AD/CESSNA 207/15, pertains to the fuel reservoir fitting of certain Cessna 207 models (s. 105.01). This directive applies to Model T207 with serial numbers ranging from 20700315 to 20700392 and also to those with lower serial numbers that have had their fuel reservoir assemblies replaced with parts from Cessna since 1 July 1975 (s. 105.02). Under this directive, it is mandatory to inspect the upper fitting of the fuel reservoir to ensure it has the correct inside diameter as per Figure 1 of Cessna Service Letter No SE77-38. Operators are also advised to refer to Cessna Service Letter No SE78-2 for additional information (s. 105.03). Compliance with this directive must be achieved within 100 hours of time in service after 31 May 1978 (s. 105.04). This requirement is critical to maintain the safety and airworthiness of the aircraft, ensuring that the fuel reservoir fittings meet the specified dimensions to prevent potential safety hazards. Operators of the affected Cessna 207 aeroplanes must ensure that the inspections are performed by qualified personnel who are knowledgeable about the specific requirements outlined in the Cessna Service Letters. The directive imposes a clear obligation on operators to adhere to these inspection protocols to ensure that the aircraft remains airworthy and compliant with safety standards (s. 105.05). Failure to comply with these ADs can lead to serious safety issues, including potential fuel system failures that could compromise the safety of the flight. Failure to comply with the requirements of AD/CESSNA 207/15 may result in serious consequences. The Civil Aviation Regulations 1998 stipulate that non-compliance with airworthiness directives can be considered a breach of the regulations (s. 105.06). Such breaches may result in civil penalties, including fines, and could also lead to the grounding of the aircraft until the required inspections and repairs are completed (s. 105.07). Additionally, severe non-compliance could result in criminal charges against the operator or responsible individuals, with potential imprisonment, further highlighting the importance of adhering to these safety directives.
