AD/GAF-N22/46 Amdt 1 - Control Wheel Assembly - Inspection and Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, are integral to ensuring the safety and regulation of civil aviation within Australia. One aspect of these regulations is the issuance of Airworthiness Directives (ADs), which serve to address specific safety concerns in the operation of aircraft. The ADs are instrumental in mitigating risks and maintaining high safety standards across the aviation sector. For example, AD/GAF-N22/46 Amendment 1 pertains to the control wheel assembly of GAF N22 and N24 series aeroplanes, requiring inspection and replacement to prevent partial failures that have been reported. This directive was introduced to address the problem of control wheel assembly failures, ensuring that such issues are promptly identified and rectified, thereby enhancing the overall safety of air travel. The objective is to maintain the airworthiness of these aircraft and protect the safety of passengers and crew.

Scope and Application

The Civil Aviation Safety Authority (CASA) Regulations 1998, under Part 39 - 105, govern the airworthiness of specific aircraft models, including the GAF N22 and N24 series aeroplanes, as specified in the Airworthiness Directive AD/GAF-N22/46 Amendment 1. This particular directive mandates the inspection and potential replacement of the control wheel assembly due to reported partial failures. The directive applies to all Nomad N22 and N24 series aircraft, requiring compliance with the specified timelines and procedures outlined in the referenced document, GAF Nomad Alert SB ANMD-27-27 Revision 1. Compliance for Part A of the Service Bulletin is to be achieved as per the requirement document, while Part B compliance must occur within 300 hours of time in service following 28 February 1983, but no later than 1 April 1983. The geographic and jurisdictional reach of this directive is confined to the Commonwealth of Australia, with CASA overseeing the implementation and enforcement of the directive across the country. There are no stated exclusions, exemptions, or thresholds in this specific directive, though broader application and restrictions may be defined in subordinate instruments.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contain a Schedule of Airworthiness Directives that includes AD/GAF-N22/46 Amendment 1. This directive pertains to the control wheel assembly of GAF N22 and N24 series aeroplanes (section 1). The directive mandates an inspection and, if necessary, replacement of the control wheel assembly (section 2). The directive applies to all Nomad N22 and N24 series aircraft (section 3). Compliance with this directive is governed by GAF Nomad Alert Service Bulletin ANMD-27-27 Revision 1, with Part A compliance following the requirements set out in the requirement document, and Part B compliance needing to be completed within 300 hours of time in service after 28 February 1983, but not later than 1 April 1983 (section 4). The obligations imposed by this directive are clear and specific. Owners and operators of the affected aircraft must ensure that the control wheel assembly is inspected and, if necessary, replaced in accordance with the guidelines provided in the GAF Nomad Alert Service Bulletin ANMD-27-27 Revision 1. This includes following the specific timelines for compliance as outlined in the directive. The directive aims to address instances of partial failure of the control wheel assembly, which could potentially compromise the safety of the aircraft (section 5). Failure to comply with the provisions of this directive may result in significant consequences. The Civil Aviation Safety Authority has the authority to enforce compliance and may take action against operators who do not adhere to the requirements. Potential consequences for non-compliance could include civil or criminal penalties, as well as the grounding of aircraft that do not meet the required safety standards. The exact penalties for breach are not specified in the text, but they could include fines and other regulatory actions (section 6).
