AD/GAF-N22/29 - Horizontal Stabiliser - Weather Proofing

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, serve to regulate various aspects of civil aviation, including the safety standards for aircraft operations. The specific legislative instrument F2006B10176, part of the Civil Aviation Regulations 1998, addresses the need to ensure the airworthiness of aircraft by issuing directives on maintenance and safety. This instrument was introduced to address the identified issue of water ingestion and storage in the horizontal stabiliser of GAF N22 and N24 series aeroplanes, which could compromise the structural integrity and safety of these aircraft. The policy objective behind this legislation is to mandate the implementation of specific maintenance actions, as outlined in the referenced Service Bulletin NMD 55-7, to prevent such occurrences and thereby maintain the safety and airworthiness of the aircraft in question. The regulation is enforced by the Civil Aviation Safety Authority (CASA) under the authority granted by the Civil Aviation Act 1988, ensuring compliance with the outlined safety directives. The directive is aimed at ensuring that all applicable models, specifically N22, N22B, and N24, are maintained according to the prescribed requirements to prevent water ingestion and subsequent storage in the horizontal stabiliser, thereby mitigating potential safety risks associated with such occurrences.

Scope and Application

The Civil Aviation Regulations 1998, under the purview of the Civil Aviation Safety Authority (CASA), applies to all models N22, N22B, and N24 aeroplanes referenced in the Nomad Service Bulletin No. NMD 55-7. This legislation mandates compliance with Airworthiness Directive AD/GAF-N22/29, which specifically addresses the issue of weather proofing in the horizontal stabiliser of the specified aircraft models. The directive requires adherence to the detailed requirements outlined in the relevant compliance document, ensuring that any water ingestion and storage issues are appropriately managed to maintain the airworthiness of these aircraft. The regulations extend across the Commonwealth of Australia, impacting operators and maintenance providers who must ensure their aircraft meet the specified safety standards. No exclusions, exemptions, or thresholds are explicitly mentioned in this particular directive, and its application is not extended or restricted through subordinate instruments in the provided text.

Key Provisions

The Civil Aviation Regulations 1998 (Cth) contain specific provisions for ensuring the safety and airworthiness of aircraft, particularly focusing on the maintenance and operational standards of various models. In Part 39 - 105, under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, there are detailed requirements for the maintenance and operational standards of GAF N22 and N24 series aeroplanes. For instance, AD/GAF-N22/29 addresses the weather proofing of the horizontal stabiliser, which is critical for ensuring the integrity of the aircraft's structural components. The directive applies to all models N22, N22B and N24 as referenced in Service Bulletin (SB) No. NMD 55-7, which outlines the necessary compliance measures. Compliance is to be achieved as detailed in the requirement document, which provides specific instructions on how to implement the airworthiness directive effectively. The obligations under the Civil Aviation Regulations 1998 are stringent and require operators of GAF N22 and N24 series aeroplanes to adhere strictly to the provisions outlined in the airworthiness directives. Operators must ensure that the horizontal stabiliser is properly weatherproofed to prevent water ingress, as specified in AD/GAF-N22/29. This involves following the detailed instructions provided in the requirement document, which may include inspections, repairs, or modifications to the aircraft. The regulations mandate that these measures are carried out by qualified personnel, ensuring that the aircraft remains in a safe and airworthy condition. Operators are also required to keep detailed records of all compliance activities, which must be maintained for future reference and potential audits by CASA. Breaches of the Civil Aviation Regulations 1998 can result in serious consequences, including both civil and criminal penalties. If an operator fails to comply with the airworthiness directives, such as neglecting to weatherproof the horizontal stabiliser as required by AD/GAF-N22/29, they may face significant fines and other penalties. The maximum penalties can vary depending on the severity of the breach, but they may include substantial financial penalties and, in some cases, criminal charges. Additionally, failure to comply with these regulations can lead to the grounding of the aircraft, which can have severe operational and financial implications for the operator. CASA has the authority to take enforcement actions, which may include imposing fines, ordering corrective actions, or even prosecuting individuals or entities that fail to meet the regulatory requirements.
