AD/DO-27/2 - Tailplane Front Spar - Modification

Overview

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, were enacted to establish and maintain safety standards within the Australian civil aviation sector, addressing the need for regulatory oversight to ensure the safety of air travel. This legislation, overseen by the Australian Parliament, aims to prevent aviation accidents and incidents by setting stringent safety directives and operational standards. The policy objective of this regulation is to mandate compliance with airworthiness directives, such as those outlined in the schedule concerning the Dornier DO-27 series aeroplanes, ensuring that aircraft maintain structural integrity and safety standards are upheld. The particular legislative instrument F2006B09297 focuses on a specific airworthiness directive for the Dornier DO-27 series aeroplanes, mandating modifications to the tailplane front spar. This directive applies to all DO27Q series aircraft prior to serial number 2139, requiring compliance with modifications detailed in Dornier Technical Bulletin No. 27/13. The directive aims to rectify potential structural issues before a specified compliance date of 1 September 1971, thereby enhancing the overall safety and reliability of these aircraft within the Australian aviation fleet.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, addresses the civil aviation safety authority's schedule of airworthiness directives, with this particular entry targeting the Dornier DO-27 series aeroplanes. This directive applies to all Dornier DO27Q series aeroplanes with serial numbers prior to 2139. The requirement is to modify the centre section of the front tailplane spar according to Dornier Technical Bulletin No. 27/13 Rectification part “B”, unless Part “A” has already been implemented. Compliance with these modifications is mandated before 1 September 1971 to ensure the airworthiness of these aircraft within the Australian jurisdiction. The directive applies to the specified aircraft and aims to ensure adherence to safety standards set by the Civil Aviation Safety Authority. The application of this legislative instrument is confined to the aviation industry, specifically targeting operators of Dornier DO-27 series aeroplanes. The regulation is geographically applicable across Australia, as it is a Commonwealth regulation. There are no stated exclusions, exemptions, or thresholds within the text of this directive. The effectiveness and enforcement of this regulation may be extended or detailed further through subordinate instruments, which can provide additional specifications or clarifications to ensure the directive is properly implemented.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority, detail the requirements for the airworthiness of certain aircraft, including the Dornier DO-27 Series aeroplanes. One such requirement is outlined in AD/DO-27/2, which pertains to the modification of the tailplane front spar for all DO27Q series aircraft prior to serial number 2139 (section 1). This modification is crucial for maintaining the safety and compliance of these aircraft with current aviation standards. According to section 1 of the regulation, the requirement is to modify the centre section of the front tailplane spar in accordance with Dornier Technical Bulletin No. 27/13 Rectification part “B” unless part “A” has already been carried out. This modification ensures that the structural integrity of the tailplane is enhanced, which is vital for the safety of the aircraft during operation. Additionally, the regulation mandates compliance with Dornier TB No. 27/13 before 1 September 1971, ensuring that all necessary modifications are completed within a specific timeframe to maintain airworthiness (section 2). The obligations imposed by this regulation on the parties or entities governed include ensuring that the aircraft in question meet the specified modification requirements. Aircraft owners, operators, and maintenance providers are required to adhere to the technical bulletins and timelines set out in the regulation. This involves conducting the necessary inspections, carrying out the modifications as specified, and ensuring that all modifications are completed and documented before the stipulated deadline. Failure to comply with these obligations can result in serious safety implications and potential non-compliance with aviation safety standards. Breaching the requirements set out in AD/DO-27/2 can lead to significant consequences. The regulation does not explicitly outline specific penalties or consequences for non-compliance in the provided text; however, non-compliance with Civil Aviation Regulations generally can result in civil and criminal penalties. Civil penalties may include fines, while criminal penalties could involve imprisonment, depending on the severity of the breach and the impact on aviation safety. The Civil Aviation Safety Authority has the authority to enforce these regulations and can take action against entities that fail to comply, ensuring that safety standards are upheld within the aviation industry.
