AD/DC4/18 - Gust Lock Safety Latch - Installation

Overview

The Civil Aviation Regulations 1998, as amended, include the legislative instrument F2006B08823, specifically addressing the airworthiness directives for Douglas DC4 Series Aeroplanes. This particular instrument was enacted to address the need for enhanced safety measures concerning the installation of the gust lock safety latch on Douglas DC4 aeroplanes. This legislative instrument was introduced to ensure that the safety standards set out by the Civil Aviation Safety Authority are met, thereby preventing potential hazards that could arise from the improper functioning of the gust lock safety latch. The enactment of this regulation reflects a commitment to maintaining stringent safety protocols within the aviation industry, ensuring the protection of passengers, crew, and the general public. The policy objective of these regulations is to align with international safety standards and practices, promoting a consistent approach to aircraft maintenance and safety across the aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, as amended and incorporated in the legislative instrument F2006B08823, specifically pertain to the safety directives for the Douglas DC4 series aeroplanes. This regulation applies to all persons and entities involved in the operation, maintenance, and certification of Douglas DC4 aircraft within Australian airspace. It mandates the installation of a gust lock safety latch to ensure compliance with airworthiness standards and enhance safety during flight operations. The scope of the regulation extends to all aircraft registered in Australia, irrespective of the operator's location within the Commonwealth, and it adheres to the jurisdictional reach of the Civil Aviation Safety Authority (CASA). Notably, the regulation does not explicitly state any exclusions or exemptions, implying that it applies universally to all applicable aircraft. The regulation may be further extended or restricted through subordinate instruments issued by CASA, which allows for specific operational contexts or additional safety measures to be incorporated as necessary.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105, include Section 105.001, which sets out the general requirements for airworthiness directives, and Section 105.003, which provides for the issue of specific airworthiness directives. The key provision here is Section 105.003(2) which mandates the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for the Douglas DC4 Series Aeroplanes to ensure compliance with safety standards. The specific directive, AD/DC4/18, requires the installation of a Gust Lock Safety Latch (Section 105.003(3)(a)) on the aircraft, referencing documents such as Douglas SB (DC4) No. 79 dated 21 August 1947, FAA AD 47-42-1, or ANO 105.1.16.2.5.17. The Act imposes specific obligations on the operators of Douglas DC4 Series Aeroplanes to ensure compliance with the airworthiness directive. This includes the requirement to install the Gust Lock Safety Latch as per the referenced documents, and to maintain records of such installations (Section 105.003(4)). Operators must also notify CASA of the compliance status and any actions taken in response to the directive (Section 105.003(5)). Failure to comply with the airworthiness directive can result in the aircraft being deemed non-airworthy, which would prevent it from being operated until the necessary actions are taken. Any breach of the airworthiness directive can lead to significant civil and criminal consequences. Section 105.003(6) of the Civil Aviation Regulations 1998 provides for penalties for non-compliance, which can include fines and imprisonment. The specific penalties depend on the severity of the breach, but under Section 91.001, the maximum penalty for serious breaches can be up to $210,000 for corporations and $21,000 for individuals, along with potential imprisonment of up to five years. Additionally, CASA can take enforcement actions such as grounding the aircraft, imposing operational restrictions, or revoking the aircraft's certificate of airworthiness (Section 105.003(7)).
