AD/GAF-N22/15 - Engine Air Intake Fairing - Inspection and Rework

Overview

The Civil Aviation Regulations 1998, amended by the Legislative instrument F2006B10161, addresses the safety and airworthiness of the GAF N22 and N24 series aeroplanes. Enacted by the Commonwealth of Australia, this legislation aims to ensure that these aircraft meet specific safety standards by mandating inspections and reworks on the engine air intake fairing for certain models. The policy objective is to enhance the safety and reliability of civil aviation operations by preventing potential mechanical failures and ensuring compliance with established safety directives. The Australian Government, through the relevant legislature, introduced these regulations to fill a gap in the oversight of aeroplane airworthiness, particularly for older models that may not have incorporated more recent modifications. The legislative instrument specifically targets all models of N22 and N22B aeroplanes that do not include GAF Mod. N226. It requires compliance within 100 hours of time in service after 30 September 1977, as outlined in GAF Alert SB No. N22.71.2. This regulation underscores the commitment to maintaining stringent safety protocols in the aviation industry, ensuring that all aircraft continue to operate within acceptable safety parameters. The requirement for inspections and reworks is a proactive measure to mitigate risks associated with the engine air intake fairing, contributing to the overall safety and efficiency of civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically under PART 39 - 105 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives, apply to all models of N22 and N22B aeroplanes that do not incorporate the GAF Mod. N226. The directive issued as AD/GAF-N22/15 pertains to the engine air intake fairing, stipulating a requirement for inspection and rework. This regulation is enforceable within the Commonwealth of Australia, ensuring that all relevant aircraft meet the safety standards set forth by the Civil Aviation Safety Authority. Compliance with this directive is mandatory and must be achieved within 100 hours of time in service following the issuance date of 30 September 1977, as detailed in GAF Alert SB No. N22.71.2. The regulations do not explicitly state any exclusions or exemptions, thus encompassing all applicable aircraft within its scope. Any further extensions or restrictions on the application of this directive are to be addressed through subordinate instruments issued by the relevant aviation authorities.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, include an Airworthiness Directive (AD) labelled AD/GAF-N22/15. This directive pertains to the engine air intake fairing of GAF N22 and N22B series aeroplanes, excluding those models that have incorporated GAF Mod. N226. The directive requires that all applicable aircraft undergo an inspection and necessary rework of their engine air intake fairings (Section 39 - 105). This compliance is to be completed within 100 hours of the aircraft's time in service following 30 September 1977, as stipulated in GAF Alert SB No. N22.71.2. The AD imposes specific obligations on aircraft operators and maintenance personnel to ensure that the engine air intake fairings of the affected aircraft models are inspected and reworked as necessary. This includes verifying the structural integrity of the fairings and replacing or repairing any components that do not meet the required safety standards. It is imperative that the rework is performed by qualified personnel who are familiar with the procedures outlined in the GAF Alert SB No. N22.71.2. Additionally, operators must maintain accurate records of all inspections and reworks performed, which may be subject to review by the Civil Aviation Safety Authority. Failure to comply with the requirements of AD/GAF-N22/15 can result in serious legal consequences. The AD is a legally binding directive, and non-compliance can lead to enforcement actions by the Civil Aviation Safety Authority. Potential penalties for non-compliance may include fines, suspension or revocation of aircraft operating certificates, and other administrative actions. The seriousness of the potential penalties reflects the importance of adhering to airworthiness directives to ensure the safety and reliability of civil aviation operations. Operators and maintenance personnel must take the directive seriously and ensure full compliance to avoid any adverse outcomes.
