Overview

The Civil Aviation Regulations 1998, established by the Australian Parliament, serve as a comprehensive legal framework to govern civil aviation activities within Australia, ensuring safety and compliance with international standards. The Civil Aviation Safety Authority (CASA) administers these regulations to uphold the safety and efficiency of the nation's aviation industry. One such regulation, F2006B10116, pertains specifically to the Grumman G21 (Goose) series aeroplanes, addressing safety concerns associated with the horizontal stabiliser lower strut fittings. This directive aims to mitigate risks by mandating inspections and life limitations for the strut fittings, thereby enhancing overall aircraft safety. The policy objective is to ensure that these aircraft components are regularly inspected for structural integrity and replaced if they exceed a specified service life, preventing potential in-flight failures that could endanger the aircraft and its occupants.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, mandate that all model G21A.10/77 Grumman Goose series aeroplanes adhere to certain airworthiness directives. These directives are imperative for ensuring the safety and structural integrity of these aircraft, particularly in relation to the horizontal stabiliser lower strut fittings. The regulations apply to all operators of these aircraft within the Commonwealth of Australia, thereby establishing a national standard for the maintenance and inspection of this critical component. The specified actions include inspecting the threaded portion of the strut lower adjustable end fitting for cracks using magnetic particle inspection and retiring the fitting from service if it has exceeded 3200 hours of operational time. This directive must be followed initially before the issuance of a Certificate of Airworthiness and subsequently at intervals not exceeding 1000 hours of time in service. The application of these regulations is comprehensive, covering all relevant aircraft within the specified model and series, and ensuring compliance with the outlined inspection and operational life limitations. The regulations establish a clear framework for maintaining the safety standards required for these aircraft, with specific thresholds and procedures for inspections and replacements. Any deviation from these directives can lead to significant safety risks, thereby necessitating strict adherence by all relevant operators.

Key Provisions

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, impose a series of directives aimed at ensuring the safety of Grumman G21 (Goose) series aeroplanes, particularly regarding the horizontal stabiliser lower strut fittings. Section AD/G21/2 outlines the mandatory inspection and life limitation requirements for these components. Firstly, it mandates a detailed inspection of the threaded portion of the strut lower adjustable end fitting, specifically part number 12561-3, to identify any cracks using a magnetic particle inspection technique (Section 1). Additionally, the regulation requires the retirement from service of these specific strut lower adjustable end fittings once they reach 3200 hours of time in service (Section 2). References to Grumman Customer Bulletin G21A No. 3 and FAA AD 53-31-2 are provided for further context and compliance standards. The obligations imposed by these regulations are stringent and require careful adherence. Operators of Grumman G21 (Goose) series aeroplanes must ensure that the specified inspections are conducted meticulously before the aircraft is issued a Certificate of Airworthiness and subsequently at intervals not exceeding 1000 hours of time in service (Section 1). Furthermore, the regulation necessitates that the identified strut lower adjustable end fittings are removed from service before they accumulate 3200 hours of operational time. This proactive approach is designed to prevent potential failures and ensure the ongoing airworthiness of the aircraft. Failure to comply with the provisions outlined in the Civil Aviation Regulations 1998 can result in significant legal and safety repercussions. Non-compliance with the inspection and life limitation requirements may lead to severe civil and criminal penalties. While specific penalties are not detailed in the excerpt, such breaches can result in fines, enforcement actions, and potentially the grounding of the aircraft until the deficiencies are rectified. Ensuring strict adherence to these directives is essential for maintaining the safety standards mandated by the Civil Aviation Safety Authority.
