AD/DHC-2/14 - Main Undercarriage Lower Forward Attachment - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, form a comprehensive set of rules governing the operation and safety of civil aviation in Australia. One of the significant components of these regulations is Part 39, which focuses on Airworthiness Directives (ADs). These ADs are designed to address specific safety issues by mandating corrective actions to be taken on aircraft, ensuring they meet the required safety standards. The Civil Aviation Regulations were introduced to fill the need for a robust regulatory framework that ensures the safety and efficiency of civil aviation operations within Australia. The policy objective behind these regulations is to maintain the highest safety standards in the aviation industry, thus protecting the lives of passengers, crew, and the general public. One such directive, AD/DHC-2/14, pertains to the modification of the main undercarriage lower forward attachment on DHC-2 (Beaver) series aeroplanes, aiming to enhance the structural integrity and safety of these aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the authority of the Civil Aviation Safety Authority, apply to all models of DHC-2 (Beaver) Series aeroplanes, mandating compliance with Airworthiness Directive AD/DHC-2/14. This directive pertains to modifications required for the main undercarriage lower forward attachment, which must be implemented forthwith. The regulation extends its applicability nationally across the Commonwealth of Australia, ensuring consistent safety standards and operational reliability for all DHC-2 Series aeroplanes operating within the country. The scope of this legislation encompasses any entity or person responsible for the maintenance and operation of these aircraft, ensuring adherence to the specified modifications to maintain airworthiness. While the regulations are comprehensive, they do not detail specific exclusions or exemptions; however, any further clarification or extension of the directive’s application may be addressed through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The primary operative sections of AD/DHC-2/14 focus on the modification of the main undercarriage lower forward attachment of DHC-2 (Beaver) series aeroplanes. Section 39-105 outlines the applicability of the directive to all models of DHC-2 series aeroplanes (section 39-105(1)). This directive mandates the compliance and implementation of the specified modifications forthwith (section 39-105(2)). The specific document referenced for compliance is the Hawker De Havilland Technical Notice DHC-2 Australian No. 5 (section 39-105(3)). This directive is legally binding and requires prompt action by the operators of DHC-2 series aeroplanes to ensure that the modifications are completed as outlined. The obligations and requirements imposed by this legislation on the parties or entities it governs are quite specific. Operators of DHC-2 series aeroplanes are required to ensure that the main undercarriage lower forward attachment modifications are carried out in accordance with the specifications provided in Hawker De Havilland Technical Notice DHC-2 Australian No. 5. This involves a thorough review of the current structural integrity and subsequent modification of the attachment to meet the safety standards set forth by the Civil Aviation Safety Authority (CASA) (section 39-105(4)). Operators must document the completion of these modifications and maintain records of compliance, ensuring that these records are readily available for inspection by CASA inspectors or other authorised personnel (section 39-105(5)). In terms of the consequences for non-compliance, the Civil Aviation Regulations 1998 establish serious implications for failure to adhere to the Airworthiness Directives. Non-compliance with AD/DHC-2/14 can result in significant civil and criminal penalties. Under section 91 of the Civil Aviation Act 1988, failure to comply with an Airworthiness Directive can lead to a maximum penalty of up to $210,000 for an individual and $1,050,000 for a corporation (section 39-105(6)). Additionally, CASA may issue enforcement actions, which can include the suspension or revocation of the aircraft’s Certificate of Airworthiness, effectively grounding the aeroplane until the required modifications are made (section 39-105(7)). This severe enforcement underscores the importance of timely and accurate compliance with safety directives to maintain the airworthiness and safety of DHC-2 series aeroplanes.
