Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to airworthiness directives issued by the Civil Aviation Safety Authority. This legislative instrument was enacted to ensure the safety of civil aviation in Australia, addressing specific issues related to aircraft maintenance and operation. The Civil Aviation (Airworthiness) Regulations of 1998 were established by the Australian Parliament to regulate the airworthiness of aircraft operating in Australian airspace, ensuring compliance with international safety standards.
A notable directive within this framework is AD/A109/19 Amendment 2, which targets Agusta A109 Series Helicopters. This directive was introduced to address the problem of cracking in the tail rotor hub of A109C helicopters, specifically those equipped with Fork Assembly Part Numbers 109-8131-05-109 and -113. The policy objective is to mitigate safety risks by mandating inspections and modifications to the affected parts, as outlined in Bollettino Technico Telegrafico No. 109-8 Rev. A and Bollettino Technico No. 109-100. The directive aims to ensure that all required inspections are completed and modifications are made by specified compliance dates.
Scope and Application
The Civil Aviation Regulations 1998, specifically under Part 39 - 105 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives, mandate particular safety measures for the Agusta A109 Series Helicopters. This legislation applies to all A109C helicopters equipped with specific tail rotor hub components, namely Fork Assembly P/N 109-8131-05-109 and -113 installed on Tail Rotor Assembly P/N 1009-8131-02-115. The directive requires these helicopters to undergo inspection and modification in accordance with specified technical bulletins, Bollettino Technico Telegrafico No. 109-8 Rev. A and Bollettino Technico No. 109-100. Compliance with the inspection requirement must be completed by 25 January 1992, while the modification must be completed prior to 31 March 1997. The amendment to the directive, effective 17 August 1995, extends the scope of the inspection to include the -113 part number grip, following the initial issue that addressed cracking of the flange of the tail rotor grip. This legislation applies nationally within the Commonwealth of Australia, overseen by the Civil Aviation Safety Authority, ensuring the safety and airworthiness of the specified helicopter models.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, contains crucial provisions for the Agusta A109 Series Helicopters. One such directive, AD/A109/19 Amendment 2, addresses the tail rotor hub of A109C helicopters equipped with certain parts (sections 1 and 2). The directive requires an inspection and modification of these helicopters to prevent cracking of the tail rotor grip. The inspection must be conducted in accordance with Bollettino Technico Telegrafico No. 109-8 Rev. A, while the modification must align with Bollettino Technico No. 100. This directive is effective from 17 August 1995 and references an earlier directive, RAI AD 95-101, for context. Compliance with these requirements is mandatory and must be completed by 31 March 1997.
The obligations imposed by this directive are clear and specific. Operators of A109C helicopters must ensure that inspections and modifications are carried out as prescribed by the relevant technical bulletins. These actions are necessary to maintain the airworthiness and safety of the aircraft. The directive mandates that inspections must be performed in line with the Bollettino Technico Telegrafico No. 109-8 Rev. A, and modifications must adhere to Bollettino Technico No. 100. This ensures that any potential issues with the tail rotor hub are identified and rectified promptly, thereby preventing potential safety hazards.
Failure to comply with the requirements of this airworthiness directive may result in significant consequences. The Civil Aviation Regulations 1998 outline penalties for non-compliance with airworthiness directives. Although the specific penalties are not detailed in the provided text, it is known that non-compliance can lead to both civil and criminal consequences. In the civil context, operators may face fines, operational restrictions, or even the grounding of affected aircraft. Criminally, individuals responsible for ensuring compliance could be prosecuted, leading to potential imprisonment or substantial fines. The exact penalties are usually determined by the severity of the breach and the specific regulations governing aviation safety.
