AD/DH114/39 - Nose Undercarriage Radius Rod Adjusting Screw - Replacement

Overview

The Civil Aviation Regulations 1998 were enacted to regulate civil aviation safety within Australia, ensuring that all aspects of civil aviation operations adhere to stringent safety standards. This legislation, which is administered by the Civil Aviation Safety Authority (CASA), was introduced to address the need for a cohesive regulatory framework that governs the safety of civil aviation across the country. The overarching policy objective is to ensure the highest possible standards of safety in civil aviation, protecting the public and enhancing the efficiency of the aviation industry. By providing a comprehensive set of regulations, the Civil Aviation Regulations 1998 aim to mitigate risks and maintain the integrity of the civil aviation system.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for the DH114 (Heron) Series Aeroplanes, with the directive AD/DH114/39 focusing on the replacement of the nose undercarriage radius rod adjusting screw. This legislation applies to all models within the DH114 series, ensuring that any aircraft of this type must comply with the specified directive. The directive mandates that the replacement of the nose undercarriage radius rod adjusting screw must be completed before 1 November 1973. The legislation encompasses aircraft operations within the Commonwealth of Australia, thus extending its jurisdictional reach across all states and territories. There are no stated exclusions or exemptions in this directive; it applies universally to the specified aircraft models within the timeframe provided. The authority to extend or restrict the application of this directive may be exercised through subordinate instruments, ensuring that compliance measures can be adapted to address any emerging safety concerns or technological advancements.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, includes specific Airworthiness Directives (ADs) that govern the maintenance and operation of certain aircraft. Section AD/DH114/39 pertains to the Hawker Siddeley TNS Heron (114) Series Aeroplanes, specifically addressing the nose undercarriage radius rod NK adjusting screw replacement. This AD applies to all models of the DH114 series. Compliance with this directive is mandatory for aircraft that were in compliance before 1 November 1973, ensuring that any changes or maintenance actions are performed according to the specifications outlined. Entities and parties governed by these regulations, such as aircraft operators and maintenance providers, must adhere to the requirements set forth in AD/DH114/39. This involves ensuring that the nose undercarriage radius rod NK adjusting screw is replaced as specified, which is critical for maintaining the airworthiness of the aircraft. The directive mandates that all affected aircraft undergo the necessary maintenance action before continuing operations. Operators must document and record the compliance with these requirements to demonstrate adherence to regulatory standards. Failure to comply with the provisions of AD/DH114/39 can lead to serious consequences. The Civil Aviation Safety Authority (CASA) may take enforcement action against non-compliant aircraft, which can include grounding the aircraft until the required maintenance is performed. Operators and maintenance providers who fail to adhere to the directive may face penalties, including fines or other sanctions. The specific penalties can vary depending on the nature and severity of the non-compliance, but they are designed to ensure that air safety standards are not compromised.
