AD/DH 104/30 - Front Seat Restraint Installation - Modification

Overview

The Civil Aviation Regulations 1998, specifically in PART 39 - 105, includes the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, which was enacted to ensure that civil aviation activities in Australia are conducted safely and efficiently. This legislative instrument addresses the need for maintaining airworthiness standards for specific aircraft types, ensuring that they meet safety regulations. The DH 104 (Dove) Series Aeroplanes Airworthiness Directive AD/DH 104/30, which requires the modification of front seat restraints by fitting a safety harness, exemplifies this effort. The directive was introduced to enhance the safety of pilots and passengers by mandating the installation of safety harnesses approved by the Secretary. The policy objective behind this directive is to mitigate the risks associated with unapproved modifications and to maintain the integrity of the aircraft’s safety systems. This legislative instrument was enacted by the Commonwealth of Australia and is part of the broader regulatory framework overseen by the Civil Aviation Safety Authority.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Airworthiness Directives (AD) applicable to the DH 104 (Dove) series aeroplanes, including AD/DH 104/30 concerning the front seat restraint installation. This legislation applies to all models of the Dove series aeroplanes and mandates that each front seat restraint installation must be modified by fitting a safety harness, following a scheme approved by the Secretary. The requirement to comply with these modifications must be met before 1 October 1973, with guidance provided by the Airworthiness Advisory Circular No. 62 dated March 1972. The Act applies to all operators and owners of the specified aircraft models within the Commonwealth of Australia, ensuring compliance with national civil aviation safety standards. The scope of this directive is clearly defined and aims to enhance safety through specific modifications to the aircraft’s seating arrangements.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, details the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives, with a particular focus on AD/DH 104/30, which pertains to the Dove series aeroplanes. This directive mandates that all Dove series aircraft models must have their front seat restraint installations modified to include the fitting of a safety harness (105.01). The modifications must align with a scheme approved by the Secretary, with detailed guidelines provided in Airworthiness Advisory Circular No. 62 dated March 1972 (105.02). The obligations under this directive are straightforward: all operators of Dove series aeroplanes must ensure that the specified modifications are carried out on their aircraft. This requirement encompasses the installation of safety harnesses in the front seats, which must be performed in accordance with the guidelines set out in the referenced advisory circular (105.03). Operators are expected to complete these modifications before the compliance deadline of 1 October 1973 (105.04). Failure to comply with the airworthiness directive AD/DH 104/30 could result in significant consequences. Under the Civil Aviation Act 1988, non-compliance may be considered a breach of safety regulations, leading to enforcement actions by CASA (105.05). The penalties for such breaches can be severe, potentially including fines and other sanctions as determined by the relevant aviation authorities (105.06). The exact penalties are not specified in the directive itself but are detailed in the overarching civil aviation legislation, which may impose substantial financial penalties and other regulatory measures to ensure compliance and maintain safety standards in the aviation industry (105.07).
