AD/DH 104/27 - Pneumatic System - Main Air Reservoirs

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve as a comprehensive framework governing aviation safety and operations within Australia. One of the legislative instruments under this Act, F2006B08869, addresses the maintenance and airworthiness of specific aircraft models. This particular instrument, known as AD/DH 104/27, targets the Hawker Siddeley DH 104 (Dove) series aeroplanes, focusing on the pneumatic system, specifically the main air reservoirs. The regulation was introduced to ensure compliance with safety standards before 31 December 1971, as outlined in Hawker Siddeley TNS CT(104) No. 223 Issue 1. The overarching policy objective of these regulations is to maintain the highest possible safety standards for civil aviation, thereby protecting passengers, crew, and the general public from potential hazards associated with aircraft operation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, with AD/DH 104/27 addressing the pneumatic system of the main air reservoirs in the DH 104 (Dove) series aeroplanes. This regulation applies to all models within this series, mandating compliance with the specified Hawker Siddeley TNS CT(104) No. 223 Issue 1 document before 31 December 1971. The directive applies to any entity or individual operating DH 104 (Dove) series aeroplanes within the Commonwealth of Australia, encompassing both commercial and private operators within the Australian airspace. While the regulation primarily targets the maintenance and safety standards of the pneumatic systems in the specified aircraft, there are no explicit exclusions or exemptions mentioned in the text provided. The scope of the Act is further extended or restricted through subordinate instruments as necessary, ensuring that all aircraft within the DH 104 series meet the stipulated safety requirements.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes Airworthiness Directives (AD) that govern the maintenance and operation of aircraft. One such directive, AD/DH 104/27, pertains to the pneumatic system of the Dove Series aeroplanes, particularly the main air reservoirs. This directive applies to all models of the Dove series (s. 1). The compliance date for this directive is before 31 December 1971, ensuring that any modifications or inspections required by the directive were completed by this deadline (s. 2). Under the Civil Aviation Regulations, the AD/DH 104/27 imposes specific obligations on aircraft owners and operators. They must ensure that the main air reservoirs of their Dove Series aeroplanes comply with the directive's requirements. This involves inspecting and, if necessary, replacing or repairing the main air reservoirs to prevent any potential failures that could compromise the aircraft's safety (s. 3). The directive references Hawker Siddeley TNS CT(104) No. 223 Issue 1 as the document that provides the technical details and specifications for the compliance measures (s. 4). Failure to comply with the AD/DH 104/27 can result in significant legal and safety consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce these directives. Any non-compliance with the AD can lead to penalties, which may include fines or other sanctions. Furthermore, operating an aircraft that does not meet the airworthiness standards set by the directive could result in the aircraft being grounded, which can have severe operational and financial implications for the operator (s. 5). The directive underscores the importance of adhering to the specified compliance date to avoid any potential legal repercussions.
