AD/G164/16 Amdt 1 - Rear Fuselage Extension - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, as amended by the Legislative instrument F2006B10101, are a comprehensive set of regulations enacted by the Australian Government to ensure the safety and efficiency of civil aviation within Australia. The regulations were enacted to address the need for a cohesive and robust regulatory framework governing civil aviation activities, aiming to protect the public and enhance the overall safety standards in the aviation sector. The Civil Aviation Safety Authority (CASA) is the principal enforcing body responsible for the administration and enforcement of these regulations. The overarching policy objective is to maintain and improve the safety of civil aviation operations through stringent regulatory oversight and the issuance of specific directives, such as the Airworthiness Directives for particular aircraft models, including the Schweizer (Grumman) G-164 (Ag-Cat) Series Aeroplanes. The specific amendment addressed in AD/G164/16 Amendment 1 pertains to the rear fuselage extension of Schweizer G-164B model aeroplanes with serial numbers ranging from 01B to 659B. This directive was introduced to ensure that the specified aircraft models comply with safety standards by mandating inspections and necessary modifications to the rear fuselage. Compliance with this directive is mandatory, requiring adherence to the timelines set forth, specifically within 100 hours of time in service after 31 January 1984 or at the next scheduled inspection for maintenance release issue, whichever is later. The directive is referenced to the Schweizer AG-CAT Service Bulletin No. 59 Revision A, providing the technical basis for the required actions.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives for Schweizer (Grumman) G-164 (Ag-Cat) Series Aeroplanes. This legislative instrument mandates certain safety measures and operational standards for aircraft of this particular model and series, ensuring that they meet the requisite safety criteria set by the Civil Aviation Safety Authority. The directive applies to all model G164B aircraft with serial numbers ranging from 01B through 659B. Compliance with the directive is mandatory, requiring that the specified inspections and modifications be conducted unless they have already been performed within 100 hours of time in service after 31 January 1984 or at the next scheduled inspection for maintenance release issue following that date. The directive is underpinned by the Schweizer AG-CAT Service Bulletin No. 59 Rev. A, which provides detailed guidance on the required actions. This regulation is geographically applicable within the Commonwealth of Australia, enforcing its standards across the nation. There are no explicit exclusions or exemptions mentioned in the directive; however, the applicability is strictly confined to the specified aircraft models and serial numbers. The scope of the directive is limited to the particular aircraft models and does not extend to other types of aircraft or aerospace vehicles. Any amendments or extensions to the application of this directive may be introduced through subordinate instruments, aligning with the overarching Civil Aviation Regulations 1998.

Key Provisions

The main sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105, address the Civil Aviation Safety Authority’s (CASA) Schedule of Airworthiness Directives. One such directive, AD/G164/16 Amendment 1, pertains to the Schweizer (Grumman) G-164 (Ag-Cat) series aeroplanes and mandates a rear fuselage extension inspection and modification (section 1/84). This directive applies to all model G164B aircraft with serial numbers ranging from 01B to 659B. Compliance with this directive requires the inspection and modification to be completed unless it has already been performed within 100 hours of time in service after 31 January 1984, or at the next scheduled inspection for maintenance release after the same date, whichever is later. The directive references the Schweizer AG-CAT Service Bulletin No. 59 Rev. A for detailed procedures and specifications. The obligations imposed by this directive on the parties and entities governed by the Civil Aviation Regulations 1998 include ensuring that the specified inspection and modification of the rear fuselage extension is performed on the applicable aircraft. Operators and owners of Schweizer (Grumman) G-164 (Ag-Cat) aeroplanes must ensure that these requirements are met to maintain the airworthiness of the aircraft. Compliance involves following the instructions outlined in the Schweizer AG-CAT Service Bulletin No. 59 Rev. A, which provides detailed guidance on how to conduct the inspection and necessary modifications. Failure to comply with the requirements set forth in this Airworthiness Directive may result in serious safety implications and potential regulatory consequences. The Civil Aviation Regulations 1998 do not explicitly detail the penalties or consequences for non-compliance with specific airworthiness directives in the legislative text provided. However, generally, non-compliance with CASA directives can lead to enforcement actions, which may include fines, penalties, and potential grounding of the aircraft until the necessary modifications are completed. The severity of these consequences can vary based on the nature and extent of the non-compliance.
