Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, encompasses various Airworthiness Directives aimed at ensuring the safety and airworthiness of aircraft in Australia. This regulation was enacted to address issues and gaps in the oversight and maintenance of civil aircraft, ensuring that they meet required safety standards. The enactment of these regulations falls under the legislative authority of the Parliament of the Commonwealth of Australia, reflecting a policy objective to maintain and enhance the safety of civil aviation in the country. One such directive, AD/BELL 205/10, targets Bell Helicopter Textron 205 Series Helicopters, specifically mandating inspections and modifications to the tail boom vertical fin of all 205A and 205A-1 models to mitigate safety risks identified post the initial manufacturing date. The directive, referenced as Bell SB No. 205A-6, stipulates compliance requirements for daily inspections and modifications to be carried out within a specified timeframe after the aircraft’s entry into service. This approach underscores the commitment to proactive safety management by ensuring that potential structural issues are identified and addressed promptly, thereby enhancing the overall safety and reliability of the aircraft in operation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the authority of the Civil Aviation Safety Authority, applies to all 205A and 205A-1 models of Bell Helicopter Textron 205 Series Helicopters, mandating an inspection and modification of the tail boom vertical fin forward. This regulation is intended to ensure the continued airworthiness of these helicopters, focusing on critical structural components that are essential for safety and performance. Compliance with this directive is mandatory, with the requirement to inspect at each daily or overnight inspection for Part 1 of the compliance document, and to complete the necessary modifications within 100 hours time in service after 2 May 1971, as outlined in Part 2 of the compliance document referenced by Bell SB No. 205A-6. The scope of this regulation is limited to the specified helicopter models and does not extend to other aircraft or aviation entities, reflecting a targeted approach to maintaining safety standards within the regulated aviation sector.

Key Provisions

The Civil Aviation Regulations 1998, specifically in PART 39 - 105, provides directives for the airworthiness of Bell Helicopter Textron 205 Series Helicopters. The main operative section, AD/BELL 205/10, pertains to the inspection and modification of the tail boom vertical fin for 205A and 205A-1 models (Section 1). This directive is grounded in Bell SB No. 205A-6, and compliance is mandated for both daily or overnight inspections and within 100 hours of time in service after 2 May 1971 (Section 2). The Act imposes several obligations on the parties or entities it governs. Primarily, operators of the Bell Helicopter Textron 205 Series must ensure that the tail boom vertical fin is inspected and, if necessary, modified according to the specified schedule and guidelines. This includes conducting a daily or overnight inspection (Section 3) and adhering to the maintenance schedule that requires modification within 100 hours after the directive's effective date (Section 4). Operators must also keep detailed records of all inspections and modifications performed on the tail boom vertical fin to demonstrate compliance with the Act. Failure to comply with the provisions of the Civil Aviation Regulations 1998 can result in serious consequences. Under Section 91 of the Civil Aviation Act 1988, non-compliance may lead to civil penalties, including fines up to $275,000 for corporations and $55,000 for individuals, as well as potential criminal penalties for more severe breaches. Additionally, the Civil Aviation Safety Authority (CASA) may take enforcement actions, such as grounding the aircraft, until compliance is achieved (Section 5). The stringent measures underscore the importance of adhering to the regulatory requirements to maintain the safety and airworthiness of the aircraft.
