Overview
The Civil Aviation Regulations 1998, enacted by the Australian Parliament, serve as the primary piece of legislation governing civil aviation within Australia. These regulations address various aspects of aviation safety, maintenance, and operational standards. One specific amendment, AD/CON/49Amdt 1, pertains to Teledyne Continental Motors Piston Engines, particularly those fitted with a Lear Siegler rotary fuel pump P/N 643367A2. This amendment was introduced to rectify a metrication error that was identified in the previously published directive, ensuring the safety and compliance of these engines in accordance with FAA AD Priority Letter 87-04-05. The primary objective of this directive is to ensure that the engines meet specific technical requirements, including the removal and re-installation of safety wires on the regulator valve cover screws, to be completed within 10 operating hours after 27 February 1987. This amendment underscores the commitment to maintaining high safety standards within the aviation industry.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39, mandates the Airworthiness Directives under which certain maintenance actions must be taken for specific aircraft components. This particular amendment, AD/CON/49Amdt 1, pertains to Teledyne Continental Motors Piston Engines, more specifically those equipped with the Lear Siegler rotary fuel pump P/N 643367A2. The directive applies to GTSIO-520-N Series engines that have this particular fuel pump installed. The regulation necessitates that actions be taken in accordance with the technical requirements outlined in the Federal Aviation Administration's AD Priority Letter 87-04-05 dated 12 February 1987. Compliance with these technical requirements must be completed within 10 operating hours following 27 February 1987, and it is imperative to note that adherence to previously issued service bulletins does not fulfil the compliance requirements of this directive. This regulation applies on a national level throughout Australia, enforced by the Civil Aviation Safety Authority. The directive does not specify any exclusions or exemptions, and compliance is mandatory for the specified engines and components.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39, section 106, mandate the implementation of the Civil Aviation Safety Authority (CASA) schedule of airworthiness directives, including AD/CON/49 Amendment 1 which addresses the rotary fuel pump P/N 643367A2 for Teledyne Continental Motors Piston Engines. These engines must be of the GTSIO-520-N Series and must be fitted with the specified Lear Siegler rotary fuel pump. The directive requires actions to be taken in line with the technical requirements outlined in the FAA AD Priority Letter 87-04-05 dated 12 February 1987. The specified actions involve the careful modification of the safety wiring and tightening of the screws on the regulator valve cover of the fuel pump to ensure safety and proper functionality.
The obligations under this directive are clear and precise. Operators of GTSIO-520-N Series engines fitted with the Lear Siegler rotary fuel pump P/N 643367A2 must comply with the outlined actions within 10 operating hours following 27 February 1987. The actions include removing the existing safety wire from the four screws on the regulator valve cover, loosening each screw by one full turn, tightening the screws to a torque of 24-27 inch pounds, and then re-installing the safety wire with .032 inch wire. It is crucial to note that prior compliance with referenced Service Bulletins does not satisfy the requirements of this directive, necessitating adherence to the specific instructions provided.
Failure to comply with the provisions of this airworthiness directive can lead to serious consequences. The regulations enforce strict adherence to ensure the safety and airworthiness of the aircraft. While the specific civil or criminal penalties are not detailed within the legislative text provided, non-compliance with CASA directives typically results in enforcement actions, which can include fines, grounding of the aircraft, and potential prosecution under relevant aviation safety legislation. The penalties for non-compliance can be severe, reflecting the importance of maintaining airworthiness standards to protect public safety.
