COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 106 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Teledyne Continental Motors Piston Engines
AD/CON/70 Carburettor Air Intake Housing 1/94
Applicability: Teledyne Continental Motors (TCM) C85, C90, O-200A, O-200B and O-240 model engines as detailed in TCM Critical Service Bulletin Number CSB93-13.
Note: This Directive is only applicable to TCM C85, C90, O-200A, O-200B and O- 240 engines fitted with carburettor air intake housing assemblies or P/N 641689 repair kit assemblies that were purchased from TCM between the dates of 1 September 1991 and 30 June 1993, and certain O-200A engines listed by serial number in CSB93-13.
Requirement: Action in accordance with Teledyne Continental Motors Critical Service Bulletin Number CSB93-13.
Note: FAA Airworthiness Directive 93-22-05 refers.
Compliance: Effective 6 January 1994:
INSPECTION PROCEDURE: Within 10 hours time in service and thereafter at intervals not to exceed 25 hours time in service until the carburettor air intake housing is replaced.
REPLACEMENT INSTRUCTIONS: Prior to installation in an aircraft.
Note: Replacement of the affected carburettor air intake housing is the terminating action for this Directive.
Background: This Directive requires the inspection, and removal from service, of certain carburettor air intake housings purchased from the manufacturer during the period September 1991 to June 1993. The requirement follows advice of cracks found in the affected air intake housings which could result in the loss of engine power due to the separation of the air valve or pieces of it.
Overview
The Civil Aviation Regulations 1998, enacted by the Australian Government, address the need for comprehensive safety standards in civil aviation, including the maintenance and airworthiness of aircraft engines. One specific aspect covered by these regulations is the safety directive concerning Teledyne Continental Motors piston engines, which was introduced to address a recognised safety issue related to certain carburettor air intake housings. The Civil Aviation Safety Authority (CASA) established this directive to ensure that aircraft equipped with specified TCM engines undergo necessary inspections and, if required, replacements to mitigate the risk of engine failure. The policy objective is to maintain high safety standards in aviation by proactively addressing potential defects in critical engine components.
The 1998 Regulations, under Part 39 - 106, mandate that certain TCM engines, specifically those with carburettor air intake housings purchased between September 1991 and June 1993, must be inspected within 10 hours of service and subsequently at intervals not exceeding 25 hours. If any defects are found, the affected housing must be replaced before further use. This directive aligns with broader aviation safety policies aimed at preventing in-flight failures and ensuring the continued reliability and safety of aircraft operations.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 106, addresses airworthiness directives that are crucial for ensuring the safety and compliance of aircraft operations within Australian airspace. This particular regulation, AD/CON/70, pertains to Teledyne Continental Motors piston engines, particularly models C85, C90, O-200A, O-200B, and O-240, which must adhere to the specified requirements if they have carburettor air intake housing assemblies or P/N 641689 repair kit assemblies procured from the manufacturer between 1 September 1991 and 30 June 1993, or if they are certain O-200A engines listed by serial number in CSB93-13. The directive mandates an inspection within 10 hours of time in service and at intervals not exceeding 25 hours until the affected carburettor air intake housing is replaced. This regulatory directive applies nationally and is enforced by the Civil Aviation Safety Authority to mitigate the risk of engine power loss due to potential cracks in the air intake housings.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39 under the Airworthiness Directives, detail the requirements for ensuring the airworthiness of certain Teledyne Continental Motors piston engines. The directive AD/CON/70, concerning the carburettor air intake housing, applies to TCM C85, C90, O-200A, O-200B and O-240 model engines, particularly those that were purchased from the manufacturer between 1 September 1991 and 30 June 1993 (subsection 106). This includes certain O-200A engines listed by serial number in CSB93-13. The directive mandates that these engines must comply with Teledyne Continental Motors Critical Service Bulletin Number CSB93-13, which provides specific instructions for addressing the issue.
Entities and individuals governed by these regulations must adhere to the outlined inspection and replacement procedures. They are required to inspect the carburettor air intake housing within 10 hours of service and subsequently at intervals not exceeding 25 hours of service until the housing is replaced (subsection 106). The replacement of the affected carburettor air intake housing must occur before the engine is reinstalled in an aircraft, and this action effectively terminates the directive's requirements.
Failure to comply with the Airworthiness Directives can lead to severe consequences. The Civil Aviation Regulations impose strict obligations to ensure the airworthiness of aircraft and their components. Breaches of these requirements may result in civil or criminal penalties. Specifically, non-compliance with airworthiness directives can lead to enforcement actions by the Civil Aviation Safety Authority, which may include fines or other penalties as stipulated in the regulations. The seriousness of the non-compliance and the potential risk to safety will be factors in determining the appropriate penalty, which can be substantial under Australian law.
