AD/AC-112/3 - Aileron Control System - Modification

Overview

The Civil Aviation Regulations 1998, as amended, are a comprehensive set of rules and standards governing all aspects of civil aviation in Australia. This legislation was enacted by the Australian Parliament to ensure the safety and efficiency of the nation's aviation industry. One of the key components of these regulations is Part 39 - 105, which includes the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. This specific legislative instrument, F2006B02187, was introduced to address safety concerns related to the aileron control system in Gulfstream (Rockwell) 112 Series Aeroplanes. The policy objective of this directive is to mandate modifications to ensure that the aileron control system meets specified safety standards, thereby reducing the risk of operational failures. Compliance with this directive is required within 100 hours' time in service after 29 October 1976, as referenced in Rockwell International Service Bulletin No. SB-112-41.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, establishes detailed airworthiness directives under the authority of the Civil Aviation Safety Authority. One such directive, AD/AC-112/3, pertains to the modification of the aileron control system for Gulfstream (Rockwell) 112 Series aeroplanes, focusing on serial numbers 6 to 474. This regulation mandates compliance within 100 hours of time in service following 29 October 1976, referencing Rockwell International Service Bulletin No. SB-112-41. The directive applies to all relevant aircraft within its specified serial range, ensuring adherence to safety standards by requiring the specified modification to be implemented. The geographic reach of this regulation is national, encompassing all operations within the Commonwealth of Australia, and it does not include any exclusions or exemptions. The application of this directive is enforced through subordinate instruments which may further detail compliance procedures and oversight mechanisms.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes an airworthiness directive (AD) pertaining to the Gulfstream (Rockwell) 112 Series Aeroplanes, particularly concerning the aileron control system modification. This directive, identified as AD/AC-112/3, mandates that all model 112 aeroplanes with serial numbers (S/Nos.) ranging from 6 to 474 must comply with the requirements set out in Rockwell International Service Bulletin No. SB-112-41. The compliance must be achieved within 100 hours of time in service after 29 October 1976. This directive is crucial for ensuring the continued airworthiness and safety of these specific aircraft models. The main obligation imposed by the AD/AC-112/3 is the requirement for the operators of the affected Gulfstream 112 Series Aeroplanes to implement the specified modifications to the aileron control system as outlined in Rockwell International SB-112-41. This includes performing the necessary modifications or checks to ensure the system meets the specified safety standards. Failure to comply with this directive within the stipulated timeframe may result in the aircraft being deemed non-airworthy, which would prevent it from being operated until the required modifications are completed. The AD underscores the importance of adhering to these safety standards to maintain the operational integrity of the aircraft. Failure to comply with the AD/AC-112/3 can have significant consequences. The Civil Aviation Safety Authority (CASA) enforces these regulations, and non-compliance can result in severe penalties. The primary civil consequence of non-compliance is the potential grounding of the affected aircraft until the required modifications are completed. Additionally, operators may face fines, enforcement actions, or other regulatory penalties imposed by CASA. The specific penalties for non-compliance are not detailed in the AD itself but can include substantial financial penalties and legal repercussions under the broader framework of the Civil Aviation Act 1988 and associated regulations. The overarching aim is to ensure that all affected aircraft meet the required safety standards to protect the public and maintain the highest levels of aviation safety.
