AD/SA-TP/5 - Throttle and CSU Controls

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, provide comprehensive regulations governing civil aviation safety within Australia. One particular area addressed by these regulations is the issuance of airworthiness directives to ensure that specific aircraft models meet safety standards. The legislation was introduced to fill a critical gap in ensuring that aircraft operations do not compromise safety, thereby protecting both passengers and the general public. The Civil Aviation Safety Authority, as the enforcing body, is mandated to issue such directives to maintain the highest standards of safety in the aviation sector. The overarching policy objective is to ensure that all civil aviation activities in Australia adhere to stringent safety requirements, thereby minimising the risk of accidents and incidents.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, mandates safety requirements for the British Aerospace (Scottish Aviation) Twin Pioneer Series Aeroplanes. This particular Airworthiness Directive, AD/SA-TP/5, applies to aeroplanes with Serial Numbers (S/No.) 507 and subsequent, where Modification (Mod.) C441 is not incorporated, and where the control console is fitted prior to E43847 Issue 20. The directive mandates compliance with the specifications outlined in Scottish Aviation Mod. No. C324 and requires actions to be taken forthwith. The legislation is enforced by the Civil Aviation Safety Authority and has a national jurisdictional reach within the Commonwealth of Australia, ensuring the safety and airworthiness of the specified aircraft are maintained to the required standards. The Act does not specify any exclusions, exemptions, or thresholds but extends its application through subordinate instruments as necessary to ensure compliance and safety.

Key Provisions

The Civil Aviation Regulations 1998 (Cth), specifically Part 39 - 105 (section 39.105), provide a detailed schedule of airworthiness directives for various aircraft, including the British Aerospace (Scottish Aviation) Twin Pioneer Series Aeroplanes. One such directive, AD/SA-TP/5, pertains to the throttle and control subsystem (CSU) controls on Twin Pioneer Series Aeroplanes with serial numbers (S/No.) 507 and subsequent, where modification (Mod.) C441 is not incorporated and where the control console is fitted prior to E43847 Issue 20, as detailed in Scottish Aviation Mod. No. C324 (section 39.105(1)). Compliance with this directive is required forthwith, meaning immediately or as soon as practically possible. Under these regulations, the main obligation for aircraft owners or operators is to ensure that the specified modifications to the throttle and control subsystem controls are completed. This involves verifying the serial number and modification status of the aircraft and ensuring that any control console installed predates E43847 Issue 20. If these conditions apply, the aircraft must be modified to comply with the specified airworthiness directive (section 39.105(2)). Failure to adhere to this requirement may compromise the safety and airworthiness of the aircraft, potentially leading to serious operational and legal consequences. In terms of enforcement and consequences, the Civil Aviation Regulations 1998 impose significant obligations on those governed by the Act. Failure to comply with airworthiness directives can result in serious civil or criminal penalties. Under the Civil Aviation Act 1988 (Cth), non-compliance with airworthiness directives can lead to enforcement actions, including fines of up to $210,000 for individuals and $1,050,000 for corporations, as well as potential imprisonment for serious breaches (section 32A). Furthermore, the operation of a non-compliant aircraft can result in the issuance of a direction to ground the aircraft, leading to operational disruptions and increased liability for the operator (section 22(1)). In addition to the civil penalties, there are also potential criminal consequences for serious breaches of the Civil Aviation Regulations 1998. Individuals who recklessly engage in conduct that creates a substantial risk of death or serious injury can face imprisonment for up to five years (section 26(1)). The severity of the penalties reflects the high stakes involved in ensuring the airworthiness and safety of aircraft under the regulatory framework established by the Civil Aviation Regulations 1998.
