AD/PA-23/63 - Heater Fuel Valve - Inspection

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority, were enacted to ensure that aircraft operating within Australian airspace meet stringent safety standards. One such legislative instrument, F2006B05490, focuses on the Piper PA-23 (Apache and Aztec) series aeroplanes, establishing an Airworthiness Directive (AD) aimed at mitigating specific safety risks associated with the heater fuel valve. The objective is to ensure the continued airworthiness of these aircraft by mandating regular inspections of the heater fuel valves within specified timeframes, thereby enhancing flight safety and preventing potential incidents. This directive is crucial in addressing known vulnerabilities and maintaining the high safety standards required by Australian civil aviation regulations. Enacted by the Parliament of Australia, the Civil Aviation Regulations 1998 are overseen by the Civil Aviation Safety Authority to ensure that all aircraft meet rigorous safety standards. The legislative instrument F2006B05490 targets the Piper PA-23 series aeroplanes, specifically addressing the risk of heater fuel valve failure through mandatory inspections. This policy aims to ensure that these aircraft remain airworthy and safe for operation within Australian airspace, thereby protecting passengers and crew, and maintaining the integrity of the national aviation safety framework. The directive was introduced to fill a critical gap in the existing regulations by providing specific, actionable measures to mitigate identified risks associated with the heater fuel valve on these aircraft models.

Scope and Application

The Civil Aviation Regulations 1998, as part of the legislative instrument F2006B05490, specifically within Part 39 - 105, addresses the safety directives for the Piper PA-23 (Apache and Aztec) Series Aeroplanes, which include models PA23-150 and PA23-160 with serial numbers ranging from 23-1 to 23-2046, as well as models PA23-235 and PA23-250 with serial numbers between 27-1 to 27-3836, and from 27-3838 to 27-3943. This regulation applies to all aircraft within these specified categories and serial numbers, mandating compliance with Airworthiness Directive AD/PA-23/63 concerning the heater fuel valve inspection, as referenced in Piper Service Bulletin No. 401. Compliance must be achieved within 100 hours of time in service after 31 July 1974. The regulation is applicable nationally, overseen by the Civil Aviation Safety Authority, ensuring uniform safety standards across the Commonwealth of Australia. This directive does not extend or restrict its application through subordinate instruments beyond the specific parameters outlined.

Key Provisions

The main operative sections of this legislation, specifically AD/PA-23/63, mandate a mandatory inspection of the heater fuel valve for Piper PA-23 (Apache and Aztec) Series Aeroplanes, particularly models PA23-150 and PA23-160 with serial numbers 23-1 to 23-2046, and models PA23-235 and PA23-250 with serial numbers 27-1 to 27-3836, and 27-3838 to 27-3943 (Section 7/74). This inspection must be conducted within 100 hours of the aircraft being in service after 31 July 1974. The directive references Piper Service Bulletin No. 401, which contains the technical specifications and procedures to be followed during the inspection. The obligations and requirements imposed by this legislation on the parties or entities it governs are primarily centred around ensuring the safety and airworthiness of the specified Piper PA-23 aeroplanes. Owners or operators of these aircraft must comply with the inspection requirements outlined in Section 7/74, ensuring that the heater fuel valve is examined and maintained according to the standards set forth in Piper SB No. 401. This involves scheduling the inspection at the appropriate time, engaging qualified personnel to perform the inspection, and ensuring that any identified issues are rectified to meet the regulatory standards. Failure to comply with the airworthiness directive could result in various consequences under the Civil Aviation Regulations 1998. Specifically, non-compliance with Section 7/74 could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The penalties for such breaches can include fines, and in severe cases, the suspension or revocation of the aircraft's certificate of airworthiness. The exact penalties are not specified within this directive but would be determined based on the severity and impact of the non-compliance on aviation safety. The implications of these penalties underscore the importance of adhering to the regulatory requirements to maintain the safety standards mandated by Australian aviation law.
