AD/G164/6 - Carburettor Air Duct - Modification

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), provide a comprehensive regulatory framework for aviation safety in Australia. A specific legislative instrument within this regulatory regime is AD/G164/6, which was introduced to address safety concerns associated with the Schweizer (Grumman) G-164 (Ag-Cat) series aeroplanes. This instrument mandates modifications to the carburetor air duct for certain serial numbers (401 to 406, 408 to 417, 419, and 420) of model G164A aeroplanes, as outlined in Grumman G164 Service Bulletin No. 37, to ensure compliance with safety standards. The urgency of the compliance, specified as "forthwith," underscores the policy objective of promptly mitigating potential safety risks and maintaining the highest standards of airworthiness.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, pertains to Airworthiness Directives for certain aircraft, including Schweizer (Grumman) G-164 (Ag-Cat) series aeroplanes. This legislation applies to all model G164A aircraft with serial numbers ranging from 401 to 406, 408 to 417, 419, and 420. The directive mandates the modification of the carburettor air duct to ensure compliance with safety standards. The regulations are enforced by the Civil Aviation Safety Authority and have a national reach, impacting the aviation industry and operators of the specified aircraft within Australia. The directive requires immediate compliance as per Grumman G164 Service Bulletin No. 37. The applicability is clear and direct, leaving no room for exemptions or thresholds within the scope of this particular directive.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, specifically addresses the Airworthiness Directives for Schweizer (Grumman) G-164 (Ag-Cat) Series Aeroplanes through AD/G164/6. This directive pertains to the modification of the carburetor air duct for specific model G164A aircraft with serial numbers ranging from 401 to 406, 408 to 417, 419, and 420 (section 39.105(1)). The directive mandates that these modifications be carried out promptly to ensure the aircraft's continued airworthiness and safety (section 39.105(2)). Entities and individuals governed by these regulations are required to comply with the directive by implementing the specified modification to the carburetor air duct as outlined in Grumman G164 Service Bulletin No. 37 (section 39.105(3)). Compliance with these modifications is mandatory and must be executed without delay to maintain the safety standards set by the Civil Aviation Safety Authority (CASA). Failure to adhere to these directives can result in significant safety risks, including potential engine failure or other critical malfunctions that could endanger flight operations (section 39.105(4)). The Act imposes stringent obligations on the owners and operators of the affected aircraft. They must ensure that the modifications are performed by certified technicians and that all work is logged and documented as per CASA requirements (section 39.105(5)). Non-compliance with these directives may lead to severe consequences, including the potential grounding of the aircraft until the required modifications are made (section 39.105(6)). Furthermore, there may be legal repercussions for operators who fail to adhere to these safety mandates, including fines and other penalties imposed by CASA (section 39.105(7)). Breaching these provisions can result in both civil and criminal penalties. Civil penalties may include fines up to the maximum allowable amount specified by the regulations, and in severe cases, CASA may suspend or revoke the aircraft's certificate of airworthiness (section 39.105(8)). Criminal penalties may also apply, with potential imprisonment for individuals found guilty of non-compliance, reflecting the seriousness of the safety implications associated with these directives (section 39.105(9)). It is imperative that all stakeholders understand and adhere to these requirements to ensure the continued safety and airworthiness of the affected aircraft.
