AD/PA-18/6 - Exhaust System - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, serve as the primary legislative framework governing civil aviation safety and operations within the country. This extensive regulatory framework is overseen by the Civil Aviation Safety Authority (CASA) and aims to ensure that civil aviation activities are conducted safely and efficiently. One specific aspect of this legislation is the issuance of Airworthiness Directives (ADs), which mandate compliance with safety standards for specific types of aircraft. For instance, AD/PA-18/6 pertains to the Piper PA-18 and 19 (Super Cub) series aeroplanes, addressing a critical safety concern related to the exhaust system. The directive mandates inspections at intervals not exceeding 100 hours of time in service to mitigate potential risks associated with exhaust system integrity. The problem or gap that AD/PA-18/6 addresses is the need for regular maintenance checks on the exhaust systems of Piper PA-18 and 19 series aeroplanes to ensure their continued airworthiness and the safety of all persons onboard. By establishing this requirement, the Civil Aviation Regulations 1998 aim to prevent potential failures that could lead to hazardous conditions or accidents. This directive is part of a broader policy objective to maintain high safety standards in civil aviation, ensuring that all aircraft meet stringent regulatory requirements to safeguard public safety.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39, specifically in Schedule 105 concerning Airworthiness Directives, governs the maintenance and operational standards of civil aircraft within Australia. This legislation applies to all Piper PA-18 and PA-19 (Super Cub) series aeroplanes, mandating a comprehensive inspection of the exhaust system at intervals not exceeding 100 hours of time in service. This requirement ensures that the aircraft meet the necessary safety standards and continue to be airworthy. The directive is applicable nationwide, encompassing both private and commercial operations of these aircraft within Australian airspace. The regulation does not explicitly exclude any specific persons, entities, or circumstances, meaning it applies universally to all operators of the specified aeroplane models. The scope of the Act is further extended through subordinate instruments that may provide additional specific guidelines or modifications to the primary directive.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the Airworthiness Directives for the Piper PA-18 and 19 (Super Cub) Series Aeroplanes. Section 3/63 focuses on the exhaust system and mandates that an inspection must be conducted. This requirement applies to all models of these aircraft as detailed in Piper Service Letter No. 324B. Compliance with this directive is expected at intervals not exceeding 100 hours of time in service, ensuring that the aircraft's exhaust system is regularly examined to maintain airworthiness. The Act imposes specific obligations on aircraft operators and maintenance personnel. Operators must ensure that the exhaust system of the Piper PA-18 and 19 Series Aeroplanes is inspected in accordance with the specified intervals. Maintenance personnel are required to conduct these inspections meticulously, following the guidelines provided in the Piper Service Letter No. 324B. The aim is to identify any potential issues such as leaks, corrosion, or structural weaknesses that could compromise the safety of the aircraft. Failure to comply with these directives can result in significant consequences. The Civil Aviation Safety Authority (CASA) has the authority to take action against non-compliant operators. Civil penalties may be imposed, which can include fines up to a substantial amount, as stipulated by the regulations. In severe cases, CASA may also suspend or revoke the airworthiness certificate of the aircraft, preventing it from operating until the necessary inspections and repairs are completed. Such actions underscore the importance of adhering to the prescribed inspection intervals to ensure the safety and continued airworthiness of the aircraft.
