AD/DO-27/5 - Fuel, Oil and Manifold Pressure Flexible Hoses - Replacement

Overview

The Civil Aviation Regulations 1998 (F2006B09300), enacted by the Commonwealth of Australia, serve to regulate civil aviation activities within Australia. One specific focus of the legislation is ensuring the airworthiness of aircraft, which is detailed in Part 39. This part provides a framework for issuing airworthiness directives to maintain safety standards. For instance, Airworthiness Directive AD/DO-27/5 targets the replacement of fuel, oil, and manifold pressure flexible hoses on Dornier DO-27 Series aeroplanes, specifically models DO-27, A-4, Q-5, and Q-6. This directive is intended to address potential safety issues with these hoses that could compromise the overall airworthiness of the aircraft, thereby ensuring compliance with safety standards before a specified date, in this case, 1 September 1971. The authority to enact these regulations is vested in the Civil Aviation Safety Authority, with the overarching policy objective being to protect public safety in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, as amended, and specifically PART 39 - 105, under the Civil Aviation Safety Authority (CASA), mandates the application of Airworthiness Directives (AD) concerning the maintenance and safety of aircraft. AD/DO-27/5 pertains to the replacement of fuel, oil, and manifold pressure flexible hoses for all Dornier DO-27 series aeroplanes, including models DO-27, A-4, Q-5, and Q-6. This directive applies to aircraft manufactured before 1 September 1971 and is documented in Dornier TB No. 27-27. The regulation is enforced within the Commonwealth of Australia, extending its jurisdiction across all states and territories. The directive does not specify exclusions or exemptions, implying that all applicable aircraft must comply with the stipulated maintenance requirements. Subordinate instruments may further detail implementation, but the primary directive remains clear in its scope and application to the designated aircraft series.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39, Section 105, detail the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, with a focus on the Dornier DO-27 Series Aeroplanes. This legislation, referenced as AD/DO-27/5, mandates the replacement of fuel, oil, and manifold pressure flexible hoses on all model DO-27, A-4, Q-5, and Q-6 aircraft. This requirement is applicable to aircraft that were in compliance before 1 September 1971, as documented in Dornier TB No. 27-27. The directive emphasises the necessity of adhering to these specifications to maintain airworthiness and ensure safety standards are met. Under this legislation, the primary obligation imposed on aircraft owners and operators is to ensure that the specified flexible hoses are replaced in accordance with the provided technical bulletin. This involves conducting a thorough inspection of the aircraft's fuel, oil, and manifold pressure systems to identify any hoses that require replacement. Compliance with this directive is essential to prevent potential failures that could compromise the safety of the aircraft during operation. The responsibility falls on the aircraft owners and operators to implement these changes and verify that all necessary modifications have been made by the specified compliance date. Failure to adhere to the provisions outlined in this legislation can result in significant consequences. The Civil Aviation Regulations 1998 stipulate that non-compliance with airworthiness directives can lead to penalties under the Civil Aviation Act 1988. The potential penalties for breaches include fines and, in severe cases, the grounding of the aircraft until the required modifications are completed. The maximum penalties can be substantial, reflecting the critical nature of maintaining airworthiness and the safety implications of non-compliance. It is therefore imperative for aircraft owners and operators to take this directive seriously and ensure full compliance to avoid any legal repercussions.
