Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, was enacted to address safety concerns related to aircraft maintenance and operation. This legislation was enacted by the Australian Commonwealth and seeks to ensure that aircraft are maintained to the highest standards of airworthiness. The problem it addresses is the risk of hydraulic hose failure in specific models of the Piper PA-42 Cheyenne III series aeroplanes, which could lead to significant operational hazards. The Civil Aviation Safety Authority, through this regulation, aims to mitigate these risks by issuing specific Airworthiness Directives that require corrective actions to be taken within a specified timeframe.
This particular regulation, AD/PA-42/11, targets the issue of hydraulic hoses in Piper PA-42 Cheyenne III and Cheyenne IIIA series aeroplanes that were found to be manufactured with material not meeting pressure requirements. The directive mandates compliance with Piper Service Bulletin No. 822 and requires corrective actions to be completed within 25 hours of the aircraft's time in service after 19 May 1986, ensuring that the identified safety concerns are promptly addressed.
Scope and Application
The Civil Aviation Regulations 1998, under PART 39 - 105, specifically address the airworthiness directives for certain Piper PA-42 Cheyenne III series aeroplanes. This regulation applies to all model PA-42 Cheyenne III aircraft with specific serial numbers and all model PA-42 Cheyenne IIIA aircraft with particular serial numbers, mandating compliance with Piper Service Bulletin No. 822. This requirement necessitates corrective action concerning the hydraulic hoses within 25 hours of time in service following 19 May 1986. The directive aims to address safety concerns arising from the use of hydraulic hoses made from materials that do not meet the necessary pressure requirements for operation in the aircraft’s hydraulic system. The regulation is applicable across the Commonwealth of Australia, overseen by the Civil Aviation Safety Authority, and it does not specify any exclusions or exemptions within the provided text. The scope of the legislation is limited to the specified serial numbers of the affected aircraft, ensuring that only those particular models are subject to these airworthiness directives.
Key Provisions
The Civil Aviation Regulations 1998, under PART 39 - 105, include a schedule of airworthiness directives specifically targeting the Piper PA-42 (Cheyenne III) series aeroplanes. The directive AD/PA-42/11 mandates that specific serial numbered Cheyenne III and Cheyenne IIIA models must comply with the action outlined in Piper Service Bulletin No. 822. These serial numbers include PA-42 models with serial numbers ranging from 42-7800001 to 42-8001106, and PA-42 Cheyenne IIIA models with serial numbers ranging from 42-8301001 to 42-5501023 and 42-5501025. This directive was issued because the hydraulic hoses on these aeroplanes were manufactured using material that does not meet the pressure requirements for safe operation in the aircraft's hydraulic system.
The directive imposes several obligations on the parties and entities it governs. Primarily, the owners and operators of the specified model aeroplanes must ensure that the hydraulic hoses are inspected and replaced in accordance with Piper Service Bulletin No. 822. This action must be completed within 25 hours of time in service after the directive was issued on 19 May 1986. Failure to comply with these requirements could result in serious safety issues, potentially leading to catastrophic failure of the hydraulic system and compromising the safety of the aircraft.
Breaching the provisions of this airworthiness directive can lead to significant legal and safety repercussions. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can be considered an offence. The penalties for such offences can be substantial, both financially and in terms of safety. For corporations, the maximum penalty can include fines up to several thousand Australian dollars. Additionally, individuals responsible for the oversight of the aircraft, such as pilots or maintenance personnel, could face personal penalties, including fines and potential disqualification from operating aircraft. The seriousness of these penalties reflects the critical importance of adhering to airworthiness directives to ensure the safety of all involved in aviation activities.
