AD/PA-23/68 - Fuel Selector Valve - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, constitute a comprehensive regulatory framework designed to ensure the safety and efficiency of civil aviation within Australia. A specific legislative instrument within this broader framework is F2006B05495, which pertains to Airworthiness Directives for certain aircraft models. This instrument was introduced to address identified safety concerns related to specific aircraft components and to ensure compliance with stringent aviation safety standards. The policy objective underlying this directive is to maintain the airworthiness of aircraft by mandating regular inspections and maintenance of critical components, thereby preventing potential safety hazards that could compromise flight safety. One such Airworthiness Directive, AD/PA-23/68, specifically targets the fuel selector valve of Piper PA-23 (Apache and Aztec) series aeroplanes. This directive mandates a thorough inspection of the fuel selector valve within 105 hours of time in service following 31 July 1975, applicable to certain serial numbers of the specified aircraft models. The directive aims to ensure that any issues with the fuel selector valve, which could potentially lead to fuel supply problems during flight, are identified and rectified promptly, thereby enhancing overall flight safety and reliability.

Scope and Application

The Civil Aviation Safety Authority (CASA) in the Commonwealth of Australia has issued the Airworthiness Directive (AD) AD/PA-23/68, which pertains specifically to the inspection of the fuel selector valve on Piper PA-23 (Apache and Aztec) series aeroplanes. This directive applies to the specified models with certain serial numbers, ensuring that maintenance and operational standards are upheld to guarantee the safety of flights. The directive requires compliance within 100 hours of time in service after 31 July 1975, underscoring the importance of regular maintenance checks on these particular aircraft components. This regulatory measure is enforced under the Civil Aviation Regulations 1998, and while it directly targets the specified aircraft models and serial numbers, the overarching aim is to maintain stringent safety standards across the aviation industry. The directive does not explicitly mention any exclusions or exemptions but is intended to apply rigorously to the identified aircraft to mitigate potential safety risks associated with fuel system failures.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105 (subsection 1), include a schedule of Airworthiness Directives (AD) that govern the operation of specific aircraft models. One such AD is AD/PA-23/68, which pertains to the Piper PA-23 (Apache and Aztec) series aeroplanes. This directive requires an inspection of the fuel selector valve for certain model numbers (subsection 2). The directive applies to model PA23-250 with specific serial numbers (subsection 3), detailing which aircraft must comply with this inspection requirement. Under this regulation, the operator of the specified Piper PA-23 series aircraft must ensure that the fuel selector valve is inspected as per the directive. This inspection must occur within 100 hours of the aircraft's time in service after 31 July 1975 (subsection 4). The directive is directly linked to Piper Service Bulletin No. 455, which provides the technical specifications and guidelines for conducting the inspection (subsection 5). Failure to comply with the requirements of AD/PA-23/68 may result in serious safety implications and legal consequences. The Civil Aviation Safety Authority (CASA) can enforce penalties and sanctions against operators who do not adhere to these airworthiness directives. The specific nature and severity of these consequences can include fines, suspension of the aircraft's airworthiness certificate, or other regulatory actions deemed necessary to ensure compliance and safety (subsection 6). The maximum penalties for non-compliance are determined by CASA, based on the severity of the breach and its impact on aviation safety. Additionally, in the event of an accident or incident resulting from non-compliance with AD/PA-23/68, the operator could face both civil and criminal liabilities. This may include lawsuits from affected parties or individuals, as well as criminal charges if the non-compliance is found to have caused harm or loss of life. The potential criminal penalties could involve substantial fines and imprisonment, reflecting the seriousness of neglecting airworthiness requirements (subsection 7). It is thus crucial for operators to strictly adhere to these regulations to avoid these severe repercussions.
