AD/G164/4 Amdt 1 - Propeller Security - Inspection

Overview

The Civil Aviation Regulations 1998, as amended by F2006B10109, address the need for stringent safety measures in the operation of Schweizer (Grumman) G-164 (Ag-Cat) Series Aeroplanes, specifically those fitted with a J5404 propeller. This legislative instrument was enacted to rectify potential safety deficiencies identified in the aircraft's propeller system, ensuring that all relevant models comply with necessary safety standards to prevent any risk of in-flight failure. The objective of this directive is to mandate immediate inspection and adherence to specified safety guidelines, as outlined in Grumman G164 Service Bulletin No. 32A or the equivalent FAA AD 66-1-2, to maintain airworthiness and protect the safety of passengers and crew. Enacted by the Parliament of the Commonwealth of Australia, the regulation aims to maintain high safety standards in the civil aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, mandates specific Airworthiness Directives for the Schweizer (Grumman) G-164 (Ag-Cat) series aeroplanes, particularly focusing on propeller security. The legislation applies to all models of the Schweizer (Grumman) G-164 series aeroplanes that are equipped with J5404 propellers. The regulations are enforced by the Civil Aviation Safety Authority (CASA) and require immediate compliance with the directive, ensuring that inspections and necessary actions are undertaken forthwith. This directive aligns with either Grumman G164 Service Bulletin No. 32A or the Federal Aviation Administration's AD 66-1-2, thereby ensuring consistency with international aviation safety standards. The scope of the regulation is specific to the mentioned aircraft models and their propeller systems, ensuring that all such aircraft maintain the required safety standards to prevent any potential hazards associated with propeller security.

Key Provisions

The Civil Aviation Regulations 1998 (sections 39.105) establish specific Airworthiness Directives (ADs) for certain aircraft models, including the Schweizer (Grumman) G-164 (Ag-Cat) series aeroplanes. In this instance, AD/G164/4 Amendment 1 specifically pertains to propeller security and inspection for all models equipped with the J5404 propeller. The directive mandates compliance with either Grumman G164 Service Bulletin No. 32A or FAA AD 66-1-2, requiring immediate action to ensure the safety of the aircraft. Under the provisions of this AD, the primary obligation imposed on aircraft operators and owners is to conduct an immediate inspection of the J5404 propeller to ascertain its security and integrity. This inspection must be completed forthwith as stipulated in the directive. Failure to comply with these requirements can result in significant safety risks, potentially leading to in-flight failures that could endanger the aircraft and its occupants. The Civil Aviation Regulations also outline the consequences for non-compliance with ADs. Specifically, failure to adhere to the requirements of AD/G164/4 Amendment 1 can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). While the Regulations do not specify maximum penalties for breaches of ADs, non-compliance can result in administrative penalties, including fines and other enforcement measures. Additionally, in severe cases, CASA may impose more stringent actions such as grounding the aircraft until the necessary inspections and repairs are completed. In summary, AD/G164/4 Amendment 1 necessitates immediate propeller inspection for Schweizer (Grumman) G-164 (Ag-Cat) aeroplanes equipped with the J5404 propeller. Compliance with either Grumman G164 Service Bulletin No. 32A or FAA AD 66-1-2 is mandatory, with immediate action required. Non-compliance may result in enforcement actions by CASA, including fines and potential grounding of the aircraft. It is imperative for aircraft operators and owners to strictly adhere to these directives to ensure the continued airworthiness and safety of their aircraft.
