AD/SA-TP/7 - Throttle and CSU Controls

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, provide a comprehensive regulatory framework to ensure the safety and efficiency of civil aviation within Australia. One of the key components of this regulatory regime is the Civil Aviation Safety Authority (CASA), which plays a pivotal role in issuing safety directives to mitigate potential risks associated with aircraft operations. The specific legislative instrument F2006B06782 (Legislative instrument) amends the Civil Aviation Regulations 1998 to include an airworthiness directive aimed at addressing issues with throttle and control system unit (CSU) controls in British Aerospace (Scottish Aviation) Twin Pioneer Series aeroplanes. This directive applies to aircraft with serial numbers 501 to 505 and is a direct response to identified safety concerns, ensuring that these aircraft meet the necessary safety standards to protect passengers, crew, and the public. The policy objective is to enhance aviation safety by mandating compliance with the specified modifications as outlined in Scottish Aviation Modification No. C344.

Scope and Application

The Civil Aviation Safety Authority's regulations, as outlined in the Civil Aviation Regulations 1998, specifically under Part 39 - 105 and the Airworthiness Directives, apply to British Aerospace (Scottish Aviation) Twin Pioneer Series aeroplanes with serial numbers ranging from 501 to 505, and those with Scottish Aviation Modification Number C344. These regulations pertain to the critical area of throttle and control system unit (CSU) controls, demanding immediate compliance to ensure the safety and airworthiness of these aircraft. The legislation applies nationally, with the Commonwealth exercising jurisdiction over civil aviation safety standards across Australia, ensuring a consistent approach to aviation safety across the country. These regulations are inclusive of all entities operating such aircraft within the Australian jurisdiction, including private and commercial operators. The geographic reach is nationwide, reflecting the Commonwealth's overarching responsibility for civil aviation safety. The regulations do not specify any exclusions or exemptions but mandate adherence to the directive without delay, emphasising the critical nature of the safety measures required. Subordinate instruments may further detail compliance procedures and requirements, but the primary directive sets forth the immediate necessity for action regarding the specified aircraft modifications.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105, focus on the Airworthiness Directives (ADs) issued by the Civil Aviation Safety Authority (CASA). One such directive is AD/SA-TP/7, which applies to the British Aerospace (Scottish Aviation) Twin Pioneer Series Aeroplanes with serial numbers (S/Nos.) ranging from 501 to 505. This directive mandates modifications to the throttle and control stick unit (CSU) controls, as outlined in the Scottish Aviation Modification No. C344, and requires compliance forthwith (s. 39-105). Essentially, it is a directive for immediate action to ensure the aircraft meet specific safety standards. The obligations and requirements imposed by AD/SA-TP/7 are primarily focused on ensuring that the throttle and CSU controls are modified to prevent certain malfunctions or failures that could compromise flight safety. The directive stipulates that all modifications must be carried out in accordance with the detailed procedures provided in the Scottish Aviation Modification No. C344. This includes any necessary inspections, repairs, or replacements to meet the updated safety standards. Operators of the Twin Pioneer Series Aeroplanes must ensure that their aircraft are inspected and modified as required by the directive to maintain compliance with civil aviation safety regulations (s. 39-105). Failure to comply with AD/SA-TP/7 can result in significant legal and safety consequences. The Civil Aviation Regulations 1998 impose penalties for non-compliance with ADs. Specifically, under section 91 of the Civil Aviation Act 1988, individuals or corporations found in breach of an AD can be subject to substantial fines. For corporations, the maximum penalty can be up to $210,000 for each occurrence of a contravention, highlighting the seriousness of non-compliance. Additionally, officers of the corporation, such as directors or managers, can face personal fines of up to $42,000. These penalties underscore the importance of adhering to ADs to ensure the safety and integrity of civil aviation operations.
