AD/AC/3 - Aileron Bellcrank Castings at Wing Station 196 - Replacement

Overview

The Civil Aviation Regulations 1998 (as amended), introduced by the Commonwealth of Australia, are a comprehensive set of rules governing the safety and operation of civil aviation within Australia. The regulations are designed to address gaps in the regulation of aviation safety and to ensure compliance with international standards. Enacted by the Australian Parliament, the policy objective of these regulations is to maintain the highest possible level of safety in civil aviation through strict adherence to airworthiness directives and safety protocols. One such directive, AD/AC/3, pertains specifically to the Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600, and 700) series aeroplanes, addressing the replacement of aileron bellcrank castings at NK Wing Station 196. This directive applies to certain model series and serial numbers, mandating compliance with either Aero Commander Service Bulletin No. 41 or FAA AD 57-9-1, and requires immediate action to ensure continued airworthiness and safety of these aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the application of airworthiness directives for specific aircraft models, in this case, the Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600, and 700) series aeroplanes. This legislation applies to the replacement of aileron bellcrank castings at NK Wing Station 196 for certain serial numbers and models, namely Model 520 S/Nos. 31 and subsequent, and all models 560, 560A, and 680. The directive mandates compliance with the specified aero Commander service bulletin or the FAA airworthiness directive, requiring immediate action. The regulations set by the Civil Aviation Safety Authority extend across the Commonwealth of Australia, ensuring that all relevant aircraft operators and maintenance providers within Australia adhere to these safety directives. The scope of this regulation is limited to the specified aircraft models and serial numbers, ensuring that only those aeroplanes identified in the directive are subject to the requirement for replacement of aileron bellcrank castings. The directive does not specify any exclusions or exemptions, implying that all applicable aircraft must comply with the regulations without exception. Additionally, while the primary regulation sets out the mandatory compliance, the application and enforcement of these directives can be further defined or extended through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The key operative sections of the Civil Aviation Regulations 1998, PART 39 - 105, specifically concerning the Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600 and 700) Series Aeroplanes, mandate compliance with the Airworthiness Directives (AD) related to aileron bellcrank castings at NK Wing Station 196. The directive requires the replacement of these castings, as specified in Aero Commander Service Bulletin No. 41 or FAA AD 57-9-1, and this compliance must be undertaken forthwith (Sections 39-105 and AD/AC/3). This Act imposes several obligations on the entities governed by it. Owners and operators of the specified Twin Commander aircraft must ensure that the aileron bellcrank castings at NK Wing Station 196 are replaced according to the specified service bulletins or AD. This involves the procurement of the necessary replacement parts and the engagement of certified technicians or engineers to perform the replacement. Documentation of the replacement process and maintenance records must be kept in compliance with other relevant aviation regulations (Sections 39-105, AD/AC/3, and referenced service bulletins). Failure to comply with the requirements of this directive can result in significant legal consequences. The Act specifies that non-compliance with airworthiness directives can be considered a breach of the Civil Aviation Regulations, potentially leading to enforcement actions. While the specific penalties for non-compliance are not detailed within this directive, general penalties for breaches of the Civil Aviation Act 1988 include fines up to $22,222 for individuals and significantly higher fines for corporations, as well as potential imprisonment terms. Additionally, non-compliance may result in the grounding of the affected aircraft until the required modifications are made, which can have serious operational and financial implications for the operators (Sections 39-105, 26A, and 26B of the Civil Aviation Act 1988).
