AD/APU/2 - Inspection, Placard, Operational Limitations and/or Modification

Overview

The Civil Aviation Regulations 1998 were enacted to establish a comprehensive regulatory framework governing all aspects of civil aviation within Australia, ensuring safety, efficiency, and consistency across the industry. This legislation was introduced to address the need for a unified set of rules and standards to govern the operation of aircraft, the qualifications of aviation personnel, and the maintenance of aircraft, amongst other things. The Civil Aviation Regulations 1998 were established by the Parliament of Australia under the authority of the Civil Aviation Act 1988. The policy objective of these regulations is to protect the public by ensuring that civil aviation operations are conducted in a safe and environmentally responsible manner. The specific legislative instrument, F2006B02436, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, focusing on auxiliary power units. This instrument addresses potential safety issues related to specific models of Airesearch auxiliary power units, requiring inspections, placards, operational limitations, and modifications to ensure continued airworthiness. The enactment of this instrument is a response to identified safety concerns that require immediate attention to prevent potential risks to flight safety. Compliance with these directives is mandatory for the specified aircraft models and serial numbers to maintain the highest safety standards in Australian civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 – 107 Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to certain auxiliary power units (APUs) installed in aircraft. This legislation mandates inspection, placard, and operational limitations and/or modifications for specific models of Airesearch auxiliary power units, namely the Model No. GTCP660-4 with serial numbers ranging from P-37501 to P-37723 and the Model No. GTC660-4R with serial numbers from P-101 to P-124, provided they have not been modified in accordance with Airesearch Service Bulletin GTCP660-49-3039. This regulation extends to all aircraft operators within Australia that are subject to the oversight of the Civil Aviation Safety Authority (CASA). Compliance with the requirements outlined in the FAA AD 75-05-17 Amendment No. 39-2357 is mandatory, with adherence as specified in the requirement document. The scope of the Act is geographically limited to Australia, and its application is enforced by the Commonwealth through CASA.

Key Provisions

The primary operative sections of the Civil Aviation Regulations 1998, Part 39 - 107 (referred to as AD/APU/2) focus on the inspection, placarding, operational limitations, and modifications of Auxiliary Power Units (APU) specifically for Airesearch Model No. GTCP660-4 with serial numbers (S/Nos.) P-37501 to P-37723 and Model No. GTC660-4R with S/Nos. P-101 to P-124, provided these have not been modified in accordance with Airesearch Service Bulletin No. GTCP660-49-3039. These sections detail the requirements for maintaining the airworthiness of these APUs to ensure safety and compliance with civil aviation standards. The Act imposes several obligations on the parties and entities it governs. Firstly, it mandates that the specified models of Airesearch APUs must undergo regular inspections to ensure they meet the airworthiness standards set forth by the Civil Aviation Safety Authority (CASA). These inspections must be conducted by appropriately certified personnel and must adhere to the guidelines provided in FAA AD 75-05-17 Amendment No. 39-2357. Additionally, the Act requires that these APUs display appropriate placards to indicate any operational limitations or modifications that have been made, ensuring that all users are aware of the conditions under which the APUs can be operated. Furthermore, the Act specifies the operational limitations and any necessary modifications that must be applied to maintain the airworthiness of the APUs, ensuring that they are used safely and effectively. In terms of consequences for non-compliance, the Act outlines several potential penalties and legal repercussions. If an entity or individual fails to adhere to the inspection, placarding, or modification requirements specified in AD/APU/2, they may face enforcement actions by CASA. These actions can include the imposition of fines, which may vary depending on the severity and frequency of the breach. Additionally, repeated non-compliance or significant breaches could lead to more severe penalties, such as suspension or revocation of the APU's airworthiness certificate. Such actions could result in the grounding of the aircraft until the APUs are brought into compliance, potentially leading to significant operational disruptions and financial losses for the affected parties.
