AD/DH 104/32 - Main and Nose Undercarriage Radius Rod Adjusting Screws - Replacement

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), encompass a comprehensive framework aimed at ensuring the safety and efficiency of civil aviation within Australia. This regulatory framework includes specific airworthiness directives that are essential for maintaining the integrity and safety standards of aircraft. One such directive, AD/DH 104/32, pertains to the Hawker Siddeley Dove Series aeroplanes and mandates the replacement of main and nose undercarriage radius rod adjusting screws. This directive was introduced to address potential safety risks associated with the undercarriage components of the Dove Series aircraft. The compliance deadline for this directive was set for 1 November 1973, ensuring that all affected aircraft would be updated to the required safety standards within the specified timeframe. The overarching policy objective of these regulations is to maintain and enhance the safety of civil aviation operations through stringent and timely compliance with airworthiness directives.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 – 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives for the DH 104 (Dove) Series Aeroplanes, mandates the replacement of main and nose undercarriage radius rod adjusting screws for all models of the DH 104 aircraft series. This directive applies to any entity or individual operating these aircraft within the Commonwealth of Australia, ensuring adherence to safety standards set forth by the Civil Aviation Safety Authority. The directive is applicable to all DH 104 series aeroplanes and must be complied with before 1 November 1973 unless the required adjustments have already been completed. The scope of this legislation is clearly defined, with a direct reference to the Hawker Siddeley TNS CT(104) No. 231 document for compliance purposes. The application of this directive is national, governing the safety standards across the entire Commonwealth of Australia. There are no exclusions or exemptions mentioned within the text of this particular directive. However, it is noted that further details or extensions might be provided through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically AD/DH 104/32, pertain to the Hawker Siddeley Dove Series aeroplanes, particularly focusing on the main and nose undercarriage radius rod adjusting screws. This regulation (section 39-105) mandates that all models of the Dove series must comply with the directive to replace the radius rod adjusting screws by 1 November 1973, or if the work has already been completed, it must be verified and recorded accordingly. The document referenced is Hawker Siddeley TNS CT(104) No. 231, which provides detailed instructions and specifications for the replacement. The obligations imposed by this Act on the parties or entities it governs include ensuring that all Dove Series aeroplanes are thoroughly inspected and, if necessary, the radius rod adjusting screws are replaced in compliance with the stipulated timeline. Operators and owners of these aircraft must maintain records of compliance and ensure that all modifications are performed by qualified personnel following the guidelines outlined in the referenced Hawker Siddeley document. This is to maintain the airworthiness and safety of the aircraft, ensuring they meet the regulatory standards set by the Civil Aviation Safety Authority (CASA). In terms of consequences, failure to comply with the AD/DH 104/32 directive can result in serious civil or criminal penalties. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives is a punishable offence. The potential penalties can include fines and, in severe cases, imprisonment for individuals or corporations responsible for the non-compliance. The exact penalties can vary depending on the severity and frequency of the breach, but the overarching intent is to enforce strict adherence to safety standards to protect public safety and aviation integrity.
