Overview

The Civil Aviation Regulations 1998, as amended by F2006B06827, aim to ensure the safety and reliability of aircraft operations within Australia. This legislative instrument, specifically addressing Part 39 - 105, focuses on the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, and more precisely, the Short SD3-30 Series Aeroplanes. The primary issue this legislation targets is the prevention of potential hazards associated with the loss of pitot heat when a generator fails, a problem identified by the United Kingdom Civil Aviation Authority (UK CAA) and addressed in the Shorts SB SD3-30-24-25 Revision 2. The policy objective is to maintain stringent safety standards, ensuring that all relevant aircraft are compliant with the specified airworthiness directives by adhering to the requirements outlined in the amendment. The directive mandates compliance at the next 'D' check or after 4800 flight hours following 30 November 1990, but no later than 1 June 1992, thereby safeguarding against operational risks.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all aircraft registered in Australia and pertains to the maintenance and safety standards that must be adhered to for such aircraft to ensure airworthiness. Within this framework, the Schedule of Airworthiness Directives, such as AD/SD3-30/26, mandates specific actions for aeroplanes of the SD3-30 series. This legislation applies to all operators of SD3-30 aeroplanes, necessitating compliance with the action requirements outlined in Shorts Service Bulletin SD3-30-24-25 Revision 2, which was mandated by the United Kingdom's Civil Aviation Authority. The directive applies to any SD3-30 aeroplane and requires compliance at the next 'D' check or after 4800 flight hours following 30 November 1990, but no later than 1 June 1992. This ensures that the pitot static heaters are maintained to prevent failures resulting from generator malfunctions. The scope of this legislation is further extended through subordinate instruments, which may provide additional details or amendments to the directives, ensuring that the aviation industry maintains the highest safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, includes a Schedule of Airworthiness Directives (ADs) that governs the maintenance and safety of aircraft. One such directive is AD/SD3-30/26, which applies to all SD3-30 series aeroplanes. This directive focuses on the requirement to implement actions regarding the pitot static heaters in compliance with the Shorts Service Bulletin (SB) SD3-30-24-25 Revision 2. A key aspect of this directive is its mandatory nature as stipulated by the UK Civil Aviation Authority (CAA). The requirement is that the specified actions must be taken at the next 'D' check or after 4800 flight hours following 30 November 1990, whichever comes later, but no later than 1 June 1992. Under this directive, the primary obligation imposed on the parties or entities it governs is to ensure that the pitot static heaters are addressed as per the outlined procedures in the Shorts SB SD3-30-24-25 Revision 2. This involves adhering to specific maintenance actions to prevent the loss of pitot heat in the event of a generator failure, which is a critical safety measure for the operation of the aircraft. The directive mandates that these actions must be carried out during the next scheduled 'D' check or within 4800 flight hours after the specified date of 30 November 1990, but in any case, before 1 June 1992. Failure to comply with the provisions of this airworthiness directive can lead to serious consequences. The Civil Aviation Regulations 1998 impose penalties for non-compliance with airworthiness directives, which can include both civil and criminal penalties. The exact nature and severity of these penalties depend on the specific circumstances and the discretion of the Civil Aviation Safety Authority (CASA). In general, the potential consequences for not adhering to the requirements of AD/SD3-30/26 could involve significant fines, suspension or revocation of the aircraft's certificate of airworthiness, or other regulatory actions deemed necessary to ensure safety and compliance with aviation regulations. The specific penalties are determined by the regulatory authority and can vary based on the severity and nature of the breach.
