AD/PC-6/5 - Fuel Valve - Inspection and Replacement

Overview

The Civil Aviation Regulations 1998 (the "Regulations") were enacted by the Australian Parliament to ensure the safety and efficiency of civil aviation within Australia. One of the significant components of these Regulations is the Airworthiness Directives (ADs) that address specific safety concerns for particular aircraft models. The Regulations provide a framework to ensure that all civil aviation operations are conducted safely and in accordance with international standards. This legislation fills a crucial gap by providing detailed safety requirements and compliance measures, thereby protecting the public and ensuring the reliability of civil aviation. The specific legislative instrument referenced, F2006B06154, pertains to a Part 39 - 105 Civil Aviation Safety Authority schedule of airworthiness directives for the Pilatus Porter PC-6 Series Aeroplanes. This directive targets a critical safety issue concerning the fuel valve on specific models of the Pilatus Porter aircraft. The directive mandates inspection and replacement of fuel valves on identified serial numbers to mitigate potential safety risks. The objective of this directive, as outlined in the Regulations, is to enhance the airworthiness of these aircraft by addressing a known safety issue, thereby protecting both the aircraft's occupants and the general public.

Scope and Application

The Civil Aviation Safety Authority (CASA) has issued a specific Airworthiness Directive (AD) under the Civil Aviation Regulations 1998, which pertains to the Pilatus Porter PC-6 Series Aeroplanes, specifically models with serial numbers within the specified range. This directive applies to all model PC-6/340 with serial numbers 338 to 350, 513, 516 to 521 and 523, as well as all other models with serial numbers 515, 522 and 524 to 580. The directive mandates that an inspection and, if necessary, the replacement of the fuel valve be conducted in accordance with the requirements set out in Pilatus Service Bulletin No. 36. The AD is designed to ensure that these aircraft meet specific safety standards, and compliance is mandatory for the aircraft within the scope of this directive. This directive extends to all aircraft owners, operators, and maintenance providers who are responsible for ensuring that the specified maintenance actions are carried out as per the regulatory requirements. The directive does not extend to aircraft outside the specified serial number ranges. The application of this directive is overseen by CASA, which may also issue further subordinate instruments to provide additional guidance or clarification as necessary.

Key Provisions

The Civil Aviation Regulations 1998 (Cth) under Part 39 - 105, specifically AD/PC-6/5, outlines the requirements for the inspection and replacement of fuel valves for certain Pilatus Porter PC-6 Series aeroplanes. This directive applies to all model PC-6/340 with serial numbers (S/Nos.) 338 to 350, 513, 516 to 521, and 523. Additionally, it applies to all models with S/Nos. 515, 522, and 524 to 580. The directive mandates compliance with the specifications detailed in Pilatus Service Bulletin No. 36. The inspection and replacement of the fuel valves are critical to ensuring the airworthiness and safety of these aircraft. The obligations imposed by this directive require aircraft operators to ensure that the specified fuel valves are inspected and, if necessary, replaced according to the detailed instructions provided in Pilatus SB No. 36. Operators must also ensure that all maintenance and inspection activities are conducted by appropriately qualified personnel and that all work is logged in the aircraft maintenance records. This includes documenting the date of inspection, the condition of the fuel valves, and any actions taken if a replacement was necessary. Compliance with these obligations is essential for maintaining the safety standards required by the Civil Aviation Safety Authority (CASA). Failure to comply with AD/PC-6/5 may result in significant consequences. Under the Civil Aviation Act 1988 (Cth), non-compliance with airworthiness directives can lead to civil penalties. Specifically, the maximum penalty for contravening a regulation such as AD/PC-6/5 is $222,200 for an individual and $1,111,100 for a body corporate. Additionally, CASA has the authority to issue a direction to rectify the non-compliance, and continued operation of the aircraft in a non-compliant state could lead to further enforcement actions, including grounding the aircraft. It is crucial for operators to adhere strictly to the requirements of this directive to avoid these potential penalties and ensure the continued safety and airworthiness of their aircraft.
