Overview

The Civil Aviation Regulations 1998, under Part 39, specifically in Schedule 105 of the Civil Aviation Safety Authority, introduces Airworthiness Directives governing the safety standards for aircraft, including the Douglas DC3 Series Aeroplanes. This particular directive, AD/DC3/14, addresses the modification of fuel tank filler caps for all models of the Douglas DC3 series. Enacted by the Civil Aviation Safety Authority, the directive aims to enhance the safety of these aircraft by ensuring that each of the four fuel tank filler cap wells is provided with a water-tight cover, allowing for unobstructed access while maintaining a secure seal. The directive was issued to ensure compliance with safety standards, mandating that the specified modifications be completed within 100 hours following 29 February 1984, with the reissue maintaining the original requirement unchanged.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all entities and individuals involved with the operation, maintenance, and certification of Douglas DC3 series aeroplanes in Australia. This includes aircraft owners, operators, maintenance personnel, and the Civil Aviation Safety Authority (CASA) as the regulatory body. The regulation mandates modifications to the fuel tank filler caps to ensure they provide a water-tight cover over each of the four fuel tank filler cap wells, with the cover consisting of a water-tight cap or lid that can be opened for unobstructed access and is hinged on a suitable mounting that makes a water-tight seal with the wing skin. The requirement must be met within 100 hours after 29 February 1984, unless already accomplished. This directive is jurisdictional across the Commonwealth and is enforced by CASA, with no changes made to the requirement from its initial issuance. The regulation does not specify exclusions or exemptions, implying that all Douglas DC3 series aeroplanes operating in Australia must comply with this directive.

Key Provisions

The key operative sections of the Civil Aviation Regulations 1998, Part 39, specifically AD/DC3/14, mandate modifications to the fuel tank filler caps for all models of Douglas DC3 Series aeroplanes. The requirement is to provide a water-tight cover over each of the four fuel tank filler cap wells. This cover must consist of a water-tight cap or lid that can be opened to provide unobstructed access to the fuel filler cap, and it must be hinged on a suitable mounting that ensures a water-tight seal with the wing skin (AD/DC3/14, section 1). Compliance with this directive must be achieved within 100 hours after 29 February 1984, unless already accomplished. The obligations imposed by this directive on the parties or entities it governs are clear and specific. Aircraft owners, operators, or maintenance personnel must ensure that the fuel tank filler caps of all Douglas DC3 Series aeroplanes are fitted with the required water-tight covers. This involves procuring the appropriate caps or lids and mounting them in such a way that they make a water-tight seal with the wing skin, ensuring that the fuel tank filler caps remain protected and secure. This modification is crucial for maintaining the safety and airworthiness of the aircraft. Breach of these requirements can lead to serious consequences. While the specific civil or criminal penalties are not detailed in the text, non-compliance with Civil Aviation Regulations is generally taken very seriously. Penalties may include fines, suspension or revocation of operating certificates, and potential legal action. In the context of aviation safety, non-compliance could also result in the grounding of the aircraft, which could have significant operational and financial implications for the operators. Therefore, adherence to these directives is not just a legal requirement but a critical safety measure.
