AD/F27/86 - Propeller Feathering Circuit - Duplicated Manual Feathering System

Overview

The Civil Aviation Regulations 1998 (Cth) are pivotal in ensuring the safety and efficiency of aviation operations within Australia, and Part 39 specifically addresses the airworthiness directives essential for maintaining the safety standards of various aircraft. One such directive, AD/F27/86, was enacted to address a critical safety issue concerning the Fokker F27 Series Aeroplanes, particularly focusing on the propeller feathering circuit and the necessity for a duplicated manual feathering system. This directive was introduced by the Civil Aviation Safety Authority (CASA) to ensure compliance before 30 September 1977, aiming to mitigate the risk of in-flight failures that could compromise the safety of passengers and crew. The underlying policy objective is to mandate rigorous safety standards and maintain the highest levels of operational safety for all civil aviation activities in Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Fokker F27 Series Aeroplanes, ensuring the safety and airworthiness of these aircraft through Airworthiness Directives. This legislation mandates that all models of the Fokker F27, as detailed in the Fokker SB 61-26 document, must comply with the requirements outlined in AD/F27/86 concerning the propeller feathering circuit and the duplicated manual feathering system. Compliance with these directives is mandatory for all Fokker F27 aircraft, requiring adherence to the specified standards before 30 September 1977. This regulation is applicable across the Commonwealth of Australia, encompassing all operators and entities involved with these aircraft within Australian jurisdiction. The scope of this legislation extends to ensuring that all Fokker F27 Series Aeroplanes meet the necessary safety and operational standards to maintain airworthiness and comply with civil aviation safety regulations.

Key Provisions

The Civil Aviation Regulations 1998 (Cth), under Part 39, specifically in regulation 105, address the airworthiness directives for Fokker F27 series aeroplanes. Regulation 105 focuses on the propeller feathering circuit and the duplicated manual feathering system (section 105.01). This directive applies to all models of the Fokker F27 series aeroplanes, as outlined in the Fokker SB 61-26 document. Compliance with this directive is required before 30 September 1977 (section 105.02). The regulations impose specific obligations on the parties or entities governed by these provisions. Operators of Fokker F27 series aeroplanes must ensure that their aircraft meet the standards set forth in the directive concerning the propeller feathering circuit and the manual feathering system. This involves adhering to the technical specifications and compliance timelines provided in Fokker SB 61-26, ensuring the aircraft are maintained in a safe and airworthy condition (section 105.03). Failure to comply with the airworthiness directive could result in serious consequences. The Civil Aviation Regulations 1998 establish that non-compliance with the specified requirements can lead to enforcement actions. The potential penalties include civil or criminal charges, depending on the severity and nature of the breach. In cases of non-compliance, the maximum penalties can be substantial, reflecting the importance of adhering to airworthiness standards to ensure public safety in aviation (section 105.04).
