AD/GAF-N22/18 - Upper Engine Cowl Left Hand Stay - Removal

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, are a comprehensive set of rules governing the safety and operation of civil aviation within the country. One specific legislative instrument, F2006B10164, addresses the issue of ensuring the airworthiness of GAF N22 and N24 series aeroplanes, specifically targeting the upper engine cowl left-hand stay. This regulation was introduced to rectify potential safety issues identified in these aircraft models and to ensure compliance with safety standards set forth by the Civil Aviation Safety Authority (CASA). The policy objective of this directive is to maintain the highest levels of safety in the civil aviation sector by mandating specific maintenance actions and timeframes for these aeroplanes, thereby protecting both passengers and crew. The directive is applicable to all models N22, N22B and N24 as referenced in GAF Service Bulletin No. N22.71.4, and requires compliance within 100 hours of time in service after 30 June 1978.

Scope and Application

The Civil Aviation Safety Authority (CASA) Regulations, specifically Part 39 - 105 of the Civil Aviation Regulations 1998, mandate the application of Airworthiness Directives (AD) to ensure the safe operation of aircraft. This regulation, identified as AD/GAF-N22/18, pertains to the removal of the upper engine cowl left-hand stay for all models N22, N22B, and N24 aeroplanes, as referenced in GAF Service Bulletin No. N22.71.4. This directive applies to aircraft operators who possess or operate these specific models within the Commonwealth of Australia, thereby extending CASA's regulatory oversight to all aviation activities under its jurisdiction. Compliance with this directive is mandatory and must be achieved within 100 hours of time in service after 30 June 1978, ensuring that the specified maintenance action is promptly undertaken to uphold the required safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, governs the maintenance and operation of aircraft in Australia. One such directive, AD/GAF-N22/18, pertains to the GAF N22 and N24 series aeroplanes (section 6/78). This directive mandates the removal of the upper engine cowl left-hand stay for all models N22, N22B, and N24 as referenced in Service Bulletin No. N22.71.4. The directive applies to aircraft that have accumulated 100 hours of time in service after 30 June 1978. Compliance with this directive is critical and must be achieved within the stipulated timeframe to ensure the continued airworthiness of the aircraft. The obligations imposed by AD/GAF-N22/18 are clear and straightforward. Aircraft operators and maintenance personnel must ensure that the upper engine cowl left-hand stay is removed as specified. This requirement is essential to comply with the safety bulletin referenced (N22.71.4). The directive necessitates that the removal be performed meticulously, adhering to the standards and procedures outlined in the relevant service bulletin. This ensures that the aircraft meets the safety and operational standards set forth by the Civil Aviation Safety Authority. Failure to comply with the provisions of AD/GAF-N22/18 can result in serious consequences. The Civil Aviation Regulations 1998 impose penalties for non-compliance with airworthiness directives. While the specific penalties are not detailed in the provided text, they can include substantial fines and, in severe cases, the grounding of the aircraft until the required modifications are completed. The severity of the penalties underscores the importance of adhering to these safety directives to maintain the safety and airworthiness of the aircraft. The consequences of non-compliance can also extend to potential criminal charges, highlighting the regulatory body’s commitment to ensuring the highest safety standards in civil aviation.
