AD/DC4/19 - Control Surface Bonding - Revision

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, address the maintenance and safety standards for civil aviation in Australia. Enacted by the Australian Government, these regulations were introduced to ensure the safe operation of aircraft within Australian airspace and to harmonise with international aviation safety standards. The legislation aims to safeguard the public by maintaining the airworthiness of aircraft and ensuring compliance with safety directives, such as those concerning the bonding of control surfaces on Douglas DC4 Series aeroplanes. The Civil Aviation Safety Authority (CASA) administers these regulations, with a policy objective to enhance safety and reduce the risk of accidents by mandating specific maintenance actions and periodic inspections. The legislative instrument F2006B08824 (Legislative instrument) amends and revises previous directives, incorporating updated safety requirements and ensuring alignment with current technological and operational standards in the aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, pertains to the maintenance and operation of Douglas DC4 Series aeroplanes. This regulation applies to all aircraft of the specified series, including those operated by airlines, private operators, and other entities involved in the aviation industry. It mandates specific safety measures, particularly concerning the bonding of control surfaces, to ensure the airworthiness and safety of these aircraft. The regulation is enforced under the authority of the Civil Aviation Safety Authority, which has jurisdiction over civil aviation matters in Australia, thereby ensuring compliance across the nation. The regulation may extend its application through subordinate instruments, which might provide additional technical details or procedural guidelines necessary for adherence to the safety directives. There are no stated exclusions or exemptions within the text provided, implying that all Douglas DC4 Series aeroplanes within Australian jurisdiction must comply with the specified directives.

Key Provisions

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, contains an Airworthiness Directive (AD) concerning the Douglas DC4 Series Aeroplanes. This AD, numbered AD/DC4/19, pertains to the control surface bonding and is a revision to previously issued documents, namely Douglas SB (DC4) No. 82 dated 27 December 1948, or ANO 105.1.16.2.5.18. Essentially, this AD mandates specific maintenance actions to ensure the structural integrity of the aeroplane's control surfaces. The key provision of AD/DC4/19 (Section 39-105) requires that all operators of Douglas DC4 Series Aeroplanes must adhere to the control surface bonding requirements outlined in the directive. These requirements involve detailed inspections and, if necessary, repairs or replacements to ensure that the control surfaces are properly bonded and free from defects that could compromise flight safety. Operators must follow the steps and procedures detailed in the referenced documents to comply with the AD. Operators of Douglas DC4 Series Aeroplanes are obligated to conduct the necessary inspections and repairs as per the AD within a specified timeframe. This includes verifying that the bonding of the control surfaces meets the safety standards set forth by the Civil Aviation Safety Authority (CASA). Failure to comply with the AD can result in the aeroplane being grounded until the required actions are completed and CASA approval is obtained. Non-compliance with the AD/DC4/19 can lead to significant consequences, including both civil and criminal penalties. Civil penalties may include fines, while criminal penalties could involve imprisonment, depending on the severity of the breach. The exact penalties are not detailed within the text of the AD but are subject to the general provisions of the Civil Aviation Act 1988 and related regulations. Operators must ensure strict adherence to the AD to avoid these serious repercussions.
