AD/PA-31/74 Amdt 1 - Hose Assembly - Inspection and Replacement

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, was enacted to ensure the safety and maintenance of aircraft within Australia's airspace. This legislative instrument addresses the critical need for standardised airworthiness directives, particularly focusing on the Piper PA-31 series aeroplanes. The problem this legislation targets is the potential for unsafe conditions in aircraft systems, which could lead to accidents and compromise flight safety. The enactment of this regulation by the Commonwealth of Australia, through its Civil Aviation Safety Authority, aims to provide clear guidelines and requirements for the inspection and replacement of hose assemblies, ensuring that all affected aircraft meet stringent safety standards. This policy objective is directly linked to the broader goal of maintaining the highest levels of aviation safety in Australia, protecting both passengers and crew. The specific amendment, AD/PA-31/74 Amendment 1, mandates that certain Piper PA-31 models undergo inspection and replacement of their hose assemblies within a specified timeframe. This directive applies to aircraft with specific serial numbers, ensuring that all affected aircraft are identified and maintained according to the outlined safety requirements. The regulation references Piper Service Bulletin No. 629 for compliance, emphasising the importance of adhering to manufacturer guidelines to ensure the airworthiness of these aircraft. By implementing these measures, the Civil Aviation Safety Authority seeks to mitigate risks associated with hose assembly failures, thereby enhancing overall aviation safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the Airworthiness Directives for the Piper PA-31 Series aeroplanes, addressing critical maintenance and safety requirements. This directive applies to specific models of the Piper PA-31 series, including PA-31 and PA-31-325 with serial numbers ranging from 31-7812016 to 31-7912004, PA-31-350 with serial numbers from 31-7852018 to 31-7952006, PA-31T1 with serial numbers from 31T-7804001 to 31T-7804011 and 31T-7904002 to 31T-7904006, and PA-31T with serial numbers from 31T-7720069 to 31T-7920008 and 31T-7920011 to 31T-7920012. Compliance with these directives is mandatory and must be completed within 25 hours of time in service after 19 December 1978. The directive focuses on the inspection and replacement of hose assemblies, as outlined in Piper Service Bulletin No. 629, ensuring the continued airworthiness of these aircraft. The regulations are enforced under the jurisdiction of the Civil Aviation Safety Authority, extending to all operations within the Commonwealth of Australia.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives (AD/PA-31/74 Amendment 1), focus on the inspection and replacement of hose assemblies for specific Piper PA-31 series aeroplanes. This directive applies to particular models and serial numbers of the PA-31, including PA-31, PA-31-325, PA-31-350, PA-31T1, and PA-31T models (s. 1/79). These models must comply with the requirements set forth in Piper Service Bulletin No. 629 within 25 hours of time in service after 19 December 1978. The regulations impose several obligations on the entities governed by this directive. Firstly, they require the inspection and, if necessary, the replacement of hose assemblies on the specified Piper PA-31 aeroplanes. This must be done within the stipulated timeframe to ensure the aircraft remains airworthy and complies with safety standards. The directive aims to prevent potential failures that could compromise the safety of the aircraft in operation. Failure to comply with these airworthiness directives can result in serious consequences. The Civil Aviation Safety Authority has the authority to enforce the regulations, and non-compliance can lead to enforcement actions. While the specific civil or criminal penalties are not detailed within the text provided, non-compliance with airworthiness directives generally can result in penalties such as fines, suspension or revocation of airworthiness certificates, and other regulatory actions. The severity of the penalties can depend on the nature and extent of the non-compliance, and the potential for harm caused by the failure to adhere to the directives.
