AD/DC3/17 - Elevator Tab Control Horn - Inspection

Overview

The Civil Aviation Regulations 1998, specifically PART 39 - 105, was enacted by the Australian Parliament to establish a robust regulatory framework for civil aviation safety. This legislative instrument aims to ensure that aircraft, including the Douglas DC3 Series Aeroplanes, meet stringent airworthiness standards. One of the directives under this Act, AD/DC3/17, focuses on the inspection of the elevator tab control horn to mitigate potential safety risks associated with this component. The policy objective is to maintain and enhance the safety of civil aviation through detailed regulatory oversight and mandatory inspections. This directive was issued to address gaps in the safety protocols for the specified aircraft models, ensuring that all relevant stakeholders comply with the required safety measures to protect passengers and crew.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, specifically addresses the Airworthiness Directives for the Douglas DC3 series aeroplanes, with a particular focus on AD/DC3/17, which pertains to the Elevator Tab Control Horn inspection. This regulation applies to all persons who hold an Air Operator Certificate (AOC) or a Permit to Operate and to any person responsible for the maintenance of Douglas DC3 aeroplanes within the Commonwealth of Australia. The geographic reach of this legislation is national, as it governs civil aviation across all states and territories. The regulation does not specify any exclusions or exemptions but mandates thorough inspections of the Elevator Tab Control Horn to ensure continued airworthiness and safety of the aircraft. Subordinate instruments may further elaborate on the inspection procedures and compliance requirements, extending or refining the application of the primary directive.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105, which pertains to the Civil Aviation Safety Authority Schedule of Airworthiness Directives, includes specific directives for the maintenance and inspection of certain aircraft models. One such directive, AD/DC3/17, applies to the Douglas DC3 Series Aeroplanes and mandates the inspection of the elevator tab control horn. This requirement is outlined in Section 1 of the document, which refers to either Douglas SB (DC3) No. 234 Section 1, FAA AD 44-15-1, or ANO 105.1.16.1.6.2. Essentially, the regulation necessitates that the elevator tab control horn of the specified aircraft model be inspected to ensure its airworthiness and safety. The obligations under AD/DC3/17 include conducting a thorough visual and physical inspection of the elevator tab control horn to detect any signs of wear, damage, or malfunction. The inspection must be performed by a qualified individual, such as a certified aircraft maintenance engineer, who is knowledgeable about the specific structural components of the Douglas DC3 Series Aeroplanes. The responsible party, which could be the aircraft owner, operator, or maintenance provider, must ensure that this inspection is completed in accordance with the stipulated guidelines and within the prescribed timeframes to maintain the airworthiness of the aircraft. Failure to comply with AD/DC3/17 may result in severe consequences. Non-compliance with airworthiness directives is a serious breach of aviation safety regulations. Civil penalties may include fines, and in more severe cases, the aircraft may be grounded until the necessary inspections and repairs are carried out. Additionally, criminal charges could be brought against the responsible party if the non-compliance leads to an incident or accident, potentially resulting in imprisonment. The Civil Aviation Safety Authority has the authority to enforce these regulations and take appropriate action to ensure adherence to safety standards.
