AD/FK-P/3 - Engine Drive Fuel Pump - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, are designed to ensure the safety and efficiency of civil aviation operations within Australia. A particular focus of this legislation is the regulation of airworthiness directives, which are mandatory orders issued by the Civil Aviation Safety Authority (CASA) to address safety issues in aircraft design, manufacture, and maintenance. The specific legislative instrument F2006B09948 pertains to airworthiness directives concerning Franklin piston engines, particularly the inspection of engine drive fuel pumps. This directive aims to mitigate the risk of fuel leaks and related mechanical failures that could compromise the safety of flights. By establishing clear inspection intervals and procedures, the regulations ensure that aircraft maintain high safety standards, thereby protecting passengers, crew, and the general public from potential hazards associated with engine malfunctions. The policy objective underpinning these regulations is to ensure that all aircraft operating in Australian airspace meet stringent safety criteria, thereby preventing accidents and incidents that could arise from engine failures. The requirement for regular inspections of the pump diaphragm and checks for fuel leaks is a direct response to identified safety issues with specific models of Franklin piston engines. CASA's role in enforcing these directives underscores the importance of proactive safety management in the aviation sector. The regulations not only mandate specific inspection intervals but also allow for certain inspections to be performed and certified by pilots, thus promoting a collaborative approach to maintaining airworthiness.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 106, specifically address airworthiness directives for certain Franklin piston engines, particularly models 6A-350-C1 and 6A-335-B1A with serial numbers meeting specific criteria. These directives apply to engines equipped with a fuel pump part number 20574, mandating that they comply with Franklin Service Bulletin No. 114. The inspection requirements outlined within this legislation are intended to ensure the continued airworthiness and safety of these engines. The inspection must be conducted by authorised personnel, with Part 1 requiring an inspection of the pump diaphragm within five hours of time in service after 6 March 1972 and subsequently at intervals not exceeding 100 hours. For Part 2, inspections for fuel leaks must be carried out within 50 hours of time in service after 6 March 1972, and can be performed by the pilot. These regulations apply to specified engine models and serial numbers, and the legislation ensures adherence through stipulated inspection intervals and permissible actions by authorised individuals. The geographic reach of these regulations is national, applying to all aircraft operating within Australia that are equipped with the specified engines. The regulations do not explicitly state any exclusions or exemptions but focus on ensuring compliance through the outlined inspection procedures. The applicability is extended to all relevant aircraft operators and maintenance personnel, ensuring that they follow the specified inspection intervals and procedures to maintain airworthiness. Additionally, the Civil Aviation Safety Authority can issue subordinate instruments to further define or refine the implementation of these directives, ensuring that they remain effective and relevant.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, establish the Airworthiness Directives concerning the Franklin Piston Engines (AD/FK-P/3). One of the key sections is the directive regarding the Engine Drive Fuel Pump Inspection (AD/FK-P/3). This directive applies to the Model 6A-350-C1 engines with serial numbers 52501 and subsequent, and Model 6A-335-B1A engines with serial numbers 56001-3 and subsequent, fitted with fuel pumps identified by Part No 20574 (Section 1). Compliance with Franklin Service Bulletin No 114 is required. The directive mandates two primary inspections. Part 1 requires inspection of the pump diaphragm within five hours of time in service after 6 March 1972 and then at intervals not exceeding 100 hours time in service thereafter (Section 2). Part 2 mandates that inspections for fuel leaks should be conducted at intervals not exceeding 50 hours time in service following the same date of 6 March 1972. Notably, the pilot can carry out and certify inspections for fuel leaks as outlined in Part 2 (Section 3). Entities governed by this Act must adhere to these inspection intervals to ensure the airworthiness of the specified engines. For Part 1, the inspection of the pump diaphragm must be conducted meticulously within the prescribed timeframes. For Part 2, while the pilot can perform the fuel leak inspection, it is still essential that this inspection is carried out at the specified intervals to maintain safety standards. Non-compliance with these inspection requirements can lead to significant safety risks and potential penalties. Failure to comply with these directives can result in serious consequences. Although the specific penalties are not detailed in the text, under the broader framework of the Civil Aviation Regulations, non-compliance with airworthiness directives can lead to enforcement actions, including fines and other regulatory penalties. These can vary depending on the severity and frequency of the non-compliance, but the potential for enforcement action underscores the importance of adhering to these inspection requirements.
