Overview
The Civil Aviation Safety Regulations 1998 (CASR 1998) were enacted to regulate the safety of civil aviation operations in Australia, addressing issues such as the airworthiness of aircraft and products. This legislation is administered by the Civil Aviation Safety Authority (CASA), a body within the Australian Government responsible for regulating and ensuring the safety of civil aviation. The CASR 1998 was introduced to establish a comprehensive framework to ensure that aircraft and aeronautical products meet the required safety standards, thereby protecting the public and enhancing the safety of civil aviation operations. The policy objective of these regulations is to ensure the highest possible levels of safety in the operation of aircraft by imposing mandatory safety standards and ensuring compliance through oversight and enforcement actions. This particular Airworthiness Directive (AD) issued under the CASR 1998 aims to address a specific safety concern related to the oil scavenge pumps in certain Aerostar aeroplanes, mandating corrective actions to prevent potential engine failures and ensure the continued safe operation of these aircraft.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically under Part 39 - 105, mandate the issuance of Airworthiness Directives (AD) by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft in the Australian airspace. The AD pertains to Aerostar (Piper/Ted Smith) 600 and 700 Series Aeroplanes, particularly the models PA-60-601, PA-60-601P, PA-60-602P, and PA-60-700P. This directive is imperative for operators of these specific aircraft models to replace certain oil scavenge pumps with approved Aerostar parts or equivalent FAA-approved parts to prevent potential engine failures. Compliance with the AD is mandatory within 50 flight hours from the directive's effective date of 10 July 2003. The AD was published in the Commonwealth of Australia Gazette on 18 June 2003, extending its jurisdictional reach across Australia. It is noteworthy that the AD does not specify exclusions or exemptions, applying universally to the identified aircraft models within the Australian jurisdiction.
Key Provisions
The Civil Aviation Safety Regulations 1998 (CASR), particularly Part 39 - 105, mandate the issuance of Airworthiness Directives (AD) by a delegate of the Civil Aviation Safety Authority (CASA) to address safety concerns in specific aircraft or aeronautical products. The AD issued here, AD/TSA-600/48, pertains to Aerostar (Piper/Ted Smith) 600 and 700 Series Aeroplanes, specifically models PA-60-601, PA-60-601P, PA-60-602P, and PA-60-700P. The directive was issued on 29 May 2003 and became effective on 10 July 2003. The directive requires the replacement of oil scavenge pumps with a specified Aerostar part number or an FAA-approved equivalent, and it prohibits the installation of any scavenge pumps listed in the directive.
Operators of the affected aircraft must comply with the AD by replacing any listed oil scavenge pumps within 50 flight hours from the effective date of the directive. The directive also mandates that no scavenge pumps listed in Table 1 of the AD be installed. This action is necessary to mitigate the risk of engine failure due to scavenge pump failure. The compliance must be executed in accordance with the instructions provided in Aerostar Mandatory Service Bulletin SB600-131A.
Failure to comply with the AD can result in significant safety risks, as failure of the scavenge pump can lead to a loss of engine power and/or engine failure. The AD specifies the required actions and the timeframe for compliance, and non-compliance could result in the aircraft being deemed unairworthy. The AD also references FAA AD 2002-24-07 Amdt 39-12972, indicating a collaborative approach to ensuring safety in the aviation sector. The AD was notified in the Commonwealth of Australia Gazette on 18 June 2003.
