AD/DHC-3/16 - Flap Control Rod Sub-Assembly

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, serves to ensure the safety and efficiency of civil aviation operations within Australia. A particular concern addressed by these regulations is the maintenance and airworthiness of aircraft to prevent accidents and incidents, ensuring passenger and crew safety. The specific legislative instrument in question, F2006B09064, pertains to Airworthiness Directives for DHC-3 (Otter) series aeroplanes, focusing on the flap control rod sub-assembly. This directive mandates actions to be taken in accordance with De Havilland Canada Engineering Bulletin "O" No 49, referencing Canadian AD 58-15, and requires compliance forthwith to maintain the safety standards of these aircraft. This regulatory framework aims to maintain the highest safety standards in civil aviation by ensuring that all aircraft meet specific airworthiness criteria.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives, govern the application of AD/DHC-3/16, which pertains to the flap control rod sub-assembly of de Havilland Canada DHC-3 (Otter) series aeroplanes. This directive applies to all models with serial numbers ranging from 2 to 292. The requirement mandates that the action be taken in accordance with de Havilland Canada Engineering Bulletin "O" No 49, with reference to Canadian Airworthiness Directive 58-15. Compliance with this directive is mandatory and must be completed forthwith, ensuring that the specified aircraft meet the necessary safety standards to maintain airworthiness. The geographic and jurisdictional reach of this directive is national, as it is issued under the Commonwealth of Australia’s regulatory framework. There are no exclusions, exemptions, or specific thresholds stated within the directive itself. The scope of the directive is limited to the specified models of the DHC-3 Otter aeroplanes, and its application extends to all operators within Australia who possess and operate aircraft within this serial number range. The regulation may be further refined or extended through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The key provisions of the Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority, involve Airworthiness Directives for DHC-3 (Otter) Series Aeroplanes. Section AD/DHC-3/16 pertains to the flap control rod sub-assembly and mandates compliance with De H Canada EB “O” No 49. This applies to all models with serial numbers 2 to 292. The requirement is to adhere to the directive immediately, with a reference to Canadian AD 58-15. The obligations imposed by this legislation on the parties or entities it governs are quite specific. Operators of DHC-3 (Otter) Series Aeroplanes must ensure that the flap control rod sub-assembly is inspected and, if necessary, repaired or replaced in accordance with the detailed instructions provided by De H Canada EB “O” No 49. This action must be carried out without delay, meaning operators need to act swiftly to ensure compliance with the directive. Operators are also expected to maintain records of the actions taken to address this directive, as well as any inspections and maintenance activities related to the flap control rod sub-assembly. The consequences for non-compliance with the provisions of this directive are significant. If an operator fails to adhere to the requirements specified in AD/DHC-3/16, they may be subject to enforcement actions by the Civil Aviation Safety Authority. The potential penalties for non-compliance can include substantial fines, with the exact amount determined by the severity of the breach. In more severe cases, the Civil Aviation Safety Authority may also suspend or revoke the airworthiness certificate of the aircraft in question, effectively grounding the aircraft until the necessary repairs or modifications are completed. These consequences underscore the importance of timely and accurate compliance with the directive.
