COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Mooney M20 Series Aeroplanes
AD/M20/39
Amdt 1
Fuel Filter Assembly 8/94
Applicability: Aircraft model M20E S/N 101 and subsequent, M20F S/N 660002 and subsequent, M20J S/N 24-0002 through 24-1030 inclusive fitted with Dukes Inc. auxiliary fuel pump incorporating carbon vanes.
Requirement: Unless previously carried out action in accordance with Mooney SB M20-222B. If carbon vanes have been replaced with nylatron vanes in accordance with Dukes Inc Mandatory Service Bulletin No 0002 dated 15 June 1993 the filter cartridge need not be installed in the filter housing if the housing is retained.
Note: FAA AD 80-13-02 amdt 39-3791 refers.
Compliance: By 30 August 1994.
Background: In the event of internal failure in the auxiliary fuel pump an inline fuel filter is installed to prevent debris damaging the engine driven pump.
This amendment raised to clarify the filter cartridge installation requirements.
Overview
The Civil Aviation Regulations 1998, enacted by the Australian Government, aim to ensure the safety and efficiency of civil aviation within Australia. One of the specific amendments within this legislation, AD/M20/39 Amendment 1, was introduced to address issues related to the fuel filter assembly for Mooney M20 series aeroplanes. This amendment was necessitated to prevent potential engine damage caused by debris in the event of an internal failure in the auxiliary fuel pump. The Civil Aviation Safety Authority (CASA) issued this directive to ensure compliance with safety standards, requiring that an inline fuel filter be installed unless specific conditions are met, such as the replacement of carbon vanes with nylatron vanes as per Dukes Inc Mandatory Service Bulletin No 0002. The objective is to maintain the airworthiness of these aircraft models and ensure the safety of all passengers and crew.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to Airworthiness Directives governing the safety of civil aviation in Australia. This particular directive, AD/M20/39 Amendment 1, applies to specific Mooney M20 Series aeroplanes, namely the M20E with serial numbers 101 and subsequent, the M20F with serial numbers 660002 and subsequent, and the M20J with serial numbers 24-0002 through 24-1030 inclusive, if they are fitted with a Dukes Inc. auxiliary fuel pump incorporating carbon vanes. The directive mandates that an inline fuel filter must be installed unless certain conditions are met, such as if the carbon vanes have been replaced with nylatron vanes as per Dukes Inc Mandatory Service Bulletin No 0002 dated 15 June 1993. The requirement aims to prevent engine damage from debris in the event of an internal failure in the auxiliary fuel pump. Compliance with this directive is mandatory by 30 August 1994, and it extends to ensuring that the installation of the filter cartridge adheres to the specified conditions. The directive is an integral part of maintaining the safety and airworthiness of the mentioned aircraft within Australian airspace, overseen by the Civil Aviation Safety Authority.
Key Provisions
The Civil Aviation Regulations 1998 (part 39-105) sets forth the requirements for the airworthiness of Mooney M20 Series aeroplanes, specifically for the fuel filter assembly as detailed in AD/M20/39 Amendment 1 (section 1). The regulation applies to aircraft model M20E with serial numbers 101 and onwards, M20F with serial numbers 660002 and onwards, and M20J with serial numbers 24-0002 through 24-1030 inclusive, which are fitted with a Dukes Inc. auxiliary fuel pump that incorporates carbon vanes (section 2). It specifies that unless a previous action has been taken in accordance with Mooney Service Bulletin M20-222B, the filter cartridge must be installed in the filter housing unless the carbon vanes have been replaced with nylatron vanes in accordance with Dukes Inc. Mandatory Service Bulletin No 0002 dated 15 June 1993, in which case the housing can be retained without the cartridge (section 3). This requirement is aimed at preventing debris from damaging the engine-driven pump in the event of internal failure in the auxiliary fuel pump (section 4).
The Act imposes obligations on aircraft owners and operators to ensure that the Mooney M20 Series aeroplanes meet the specified airworthiness requirements. Specifically, they must verify that the appropriate modifications have been made to the fuel filter assembly in accordance with the regulations. If carbon vanes have been replaced with nylatron vanes, they must ensure that the filter housing is retained without the cartridge. Conversely, if the carbon vanes have not been replaced, they must ensure that the filter cartridge is installed in the filter housing. This obligation extends to ensuring compliance by the specified date, which is 30 August 1994 (section 5).
Failure to comply with the provisions of the Civil Aviation Regulations 1998 can lead to various consequences. While the specific civil or criminal penalties are not detailed in the text, non-compliance with airworthiness directives can typically result in enforcement actions by the Civil Aviation Safety Authority. These actions may include fines, grounding of the aircraft, or other regulatory penalties. Furthermore, operating an aircraft that does not meet the required airworthiness standards can pose significant safety risks, potentially leading to accidents or incidents that could result in severe consequences for passengers, crew, and the public. It is therefore imperative for aircraft owners and operators to adhere strictly to the specified requirements to ensure the safety and compliance of their aircraft (section 6).
