AD/PA-20/9 - Exhaust System - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, aim to ensure the safety and efficiency of civil aviation within the country. This legislation includes specific regulations for various aircraft, addressing potential safety concerns and maintaining high standards in the aviation industry. The Piper PA-20 Series Aeroplanes Exhaust System Inspection directive, AD/PA-20/9, falls under this regulatory framework. This directive, applicable to all models of the Piper PA-20 aeroplanes, mandates inspections of the exhaust system at intervals not exceeding 100 hours of time in service. The directive references Piper SB No 324B, which provides the technical basis for these inspections. This regulation is designed to ensure that the exhaust systems of these aircraft are maintained in a safe and operational condition, thereby preventing potential safety hazards. The policy objective behind this regulation is to enhance the safety of civil aviation by ensuring that aircraft components, such as the exhaust system, are regularly inspected and maintained according to specified intervals. By implementing this directive, the Civil Aviation Safety Authority aims to mitigate the risk of in-flight failures or incidents related to the exhaust system, thereby protecting passengers, crew, and the general public. The regulation underscores the importance of regular and thorough maintenance checks in ensuring the airworthiness of aircraft, thereby contributing to the overall safety of the national airspace.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all Piper PA-20 (Pacer) series aeroplanes operated within Australia. This legislation mandates that every operator of these aircraft must ensure the exhaust system is inspected at intervals not exceeding 100 hours of time in service. The regulations set forth by the Civil Aviation Safety Authority (CASA) are intended to maintain the airworthiness of these aircraft, ensuring safety standards are consistently met. The applicability extends to all models of the Piper PA-20 series, requiring adherence to the specified inspection intervals to maintain compliance with the safety directives. The regulations do not specify exclusions or exemptions, thus applying universally to all relevant aircraft within the jurisdiction. Any further specification or clarification may be provided through subordinate instruments issued by CASA, which may elaborate on implementation procedures or additional requirements.

Key Provisions

The key operative sections of the Civil Aviation Regulations 1998, specifically in relation to the Piper PA-20 (Pacer) Series Aeroplanes, are set out in AD/PA-20/9 (1). This directive pertains to the inspection of the exhaust system of all models in this series. According to this directive, the inspection must be conducted at intervals not exceeding 100 hours of time in service, as per Piper SB No 324B (2). These requirements are designed to ensure the continued airworthiness and safety of the aircraft by preventing potential failures in the exhaust system that could compromise flight safety. Under this regulation, operators of Piper PA-20 (Pacer) Series Aeroplanes are obligated to ensure that the exhaust system inspections are carried out as specified in the directive. The inspections must be meticulous and in accordance with the documented procedures outlined by Piper SB No 324B (3). Operators are responsible for maintaining accurate records of each inspection, including the date, the duration of the aircraft's time in service since the last inspection, and the condition of the exhaust system as determined by the inspection. These records must be readily available for review by the Civil Aviation Safety Authority (CASA) upon request. Failure to comply with the requirements stipulated in AD/PA-20/9 can lead to serious consequences. Firstly, any breach of these regulations can result in the aircraft being deemed unairworthy, which may lead to grounding of the aircraft until the necessary inspections are completed and any deficiencies are rectified (4). Moreover, there are legal and financial repercussions for non-compliance. Operators found to be in breach of these provisions may face enforcement actions, including fines, penalties, or even prosecution under the Civil Aviation Act 1988 (5). The severity of the penalties can depend on the nature and extent of the breach, but they are designed to enforce strict adherence to safety regulations to protect public safety and ensure the integrity of civil aviation operations in Australia.
