AD/DHA-3/14 - Fairey-Reed Propellers - Spinner Removal

Overview

The Civil Aviation Regulations 1998, as amended, are a critical component of Australia's regulatory framework governing aviation safety and operations. This Act, enacted by the Parliament of Australia, aims to ensure the safety of civil aviation within the country by establishing stringent regulations and standards. One such regulation pertains to the airworthiness of aircraft, specifically addressing the safety concerns associated with the Fairey-Reed Propellers on DHA-3 (Drover) Series Aeroplanes. The policy objective of this regulation is to mitigate risks associated with the type A66753/X1 propeller and its associated spinner components, which have been identified as potential safety hazards. The specific Airworthiness Directive AD/DHA-3/14 mandates the immediate removal of the spinner nose and body assemblies from the type A66753/X1 propellers, allowing only the spinner back plate assembly to remain. This directive applies to all models equipped with type A66753/X1 propellers and type A66870 Marks 2, 3, and 4 spinners. Compliance with this directive is required forthwith, underscoring the urgency and importance of addressing these safety issues to protect both the aircraft and those onboard.

Scope and Application

The Civil Aviation Safety Authority (CASA) has issued Airworthiness Directive AD/DHA-3/14, which applies to all Drover Series Aeroplanes equipped with Fairey-Reed propellers that have type A66753/X1 propellers and type A66870 Mark 2, 3, or 4 spinners. This directive mandates the immediate removal of the spinner nose and body assemblies, ensuring that only the spinner back plate assembly remains installed. Compliance with these requirements is mandatory, and failure to adhere to the directive could result in safety issues and potential penalties. This regulation is enforced under the Civil Aviation Regulations 1998, which have jurisdiction across the Commonwealth of Australia and are applicable to all relevant aircraft and operators within the national airspace. The directive does not specify any exclusions or exemptions, thereby applying broadly to all relevant aircraft and operators. CASA may extend or clarify the application of this directive through subordinate instruments as necessary.

Key Provisions

The key operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105, outline the requirements for the Airworthiness Directives (AD) concerning the Fairey-Reed Propellers and spinner removal on DHA-3 (Drover) series aeroplanes. The directive AD/DHA-3/14 (sections 1-5) mandates the removal of spinner nose and body assemblies from certain propeller models, namely those with type A66753/X1 propellers and type A66870 Marks 2, 3, and 4 spinners. This directive is applicable to all models that meet the specified criteria and requires compliance without delay. These provisions impose clear obligations on the parties governed by the Act. Operators and owners of DHA-3 (Drover) series aeroplanes must ensure that the spinner nose and body assemblies are removed as per the directive AD/DHA-3/14. The directive mandates that either the spinner nose and body assemblies must be removed, leaving only the spinner back plate assembly installed, or the aeroplanes must comply with the Australian National Standard (ANO) 105.1.14.0.1.2, Issue 2. This requirement must be met forthwith, indicating the urgency and importance of the directive. Failure to comply with the Airworthiness Directives under the Civil Aviation Regulations 1998 may result in various penalties and consequences. Civil aviation offences related to non-compliance with ADs can lead to substantial fines and, in severe cases, imprisonment. The exact penalties are determined by the specific breaches and the discretion of the court, but they can be significant, reflecting the critical nature of ensuring airworthiness. It is essential for operators and owners to adhere to these directives to avoid any legal repercussions and to maintain the safety and compliance of their operations.
