AD/BELL 205/15 - Tail Rotor Hub Assembly - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form a comprehensive framework to ensure the safety and efficiency of civil aviation within the country. Among these regulations, Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives specifically addresses the airworthiness directives concerning various aircraft models, including the Bell Helicopter Textron 205 Series Helicopters. This legislation was introduced to fill the gap in ensuring the ongoing airworthiness of aircraft by mandating specific maintenance and inspection requirements. The policy objective of this regulatory framework is to maintain high safety standards and prevent potential hazards by enforcing rigorous inspection intervals and compliance measures, as exemplified by the requirement for inspecting the Tail Rotor Hub Assembly of the Bell Helicopter Textron 205 Series Helicopters every 25 hours of service following a specified date. The Civil Aviation Regulations 1998 empower the Civil Aviation Safety Authority to issue these airworthiness directives, thereby ensuring that operators of the Bell Helicopter Textron 205 Series adhere to stringent safety protocols. This legislative measure underscores the commitment to safeguarding public safety by mandating compliance with detailed inspection and maintenance schedules. Such directives are crucial in mitigating risks associated with aircraft operation, thereby reinforcing the overarching goal of maintaining high safety standards in the aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives, governs the maintenance and safety requirements of aircraft within Australia. Under this legislation, the Airworthiness Directive AD/BELL 205/15 pertains to all Bell Helicopter Textron 205 Series helicopters, particularly those model 205A-1 equipped with Tail Rotor Hub Assembly P/N 212-010-701. This directive mandates inspections of the tail rotor hub assembly at intervals not exceeding 25 hours of time in service after the specified date of 31 October 1973. This requirement ensures compliance with Bell SB No. 205-05-73-5, thereby maintaining the airworthiness and safety standards of these aircraft. The legislation applies to the aircraft themselves, their operators, and maintenance personnel, ensuring a comprehensive approach to aviation safety. The scope of this directive is national, operating under the Commonwealth of Australia’s jurisdiction, with no stated exclusions or exemptions, and its enforcement may be extended or specified further through subordinate instruments.

Key Provisions

The main operative sections of this legislative instrument, specifically AD/BELL 205/15, focus on the mandatory inspection of the Tail Rotor Hub Assembly for Bell Helicopter Textron 205 Series Helicopters (section 10/73). This directive applies to all model 205A-1 helicopters equipped with Tail Rotor Hub Assembly part number 212-010-701, as referenced in Service Instruction 205-38 (section 10/73). Compliance with this directive is governed by Bell Service Bulletin No. 205-05-73-5, and inspections must be conducted at intervals not exceeding 25 hours of time in service after 31 October 1973 (section 10/73). The Civil Aviation Safety Authority imposes several obligations on the parties and entities governed by this Act. Operators of the affected Bell Helicopter Textron 205 Series Helicopters are required to ensure that the inspections of the Tail Rotor Hub Assembly are performed at the specified intervals, as mandated by section 10/73. This includes adherence to the guidelines and instructions provided in Bell Service Bulletin No. 205-05-73-5. Furthermore, operators must maintain accurate records of all inspections carried out, ensuring that the inspections are documented in accordance with the regulatory requirements. Failure to comply with the inspection requirements set out in AD/BELL 205/15 can result in significant civil and criminal consequences. Under the Civil Aviation Act 1988, non-compliance may be considered an offence, potentially leading to enforcement actions by the Civil Aviation Safety Authority. Additionally, depending on the severity of the breach, the operator could face financial penalties. The specific maximum penalties for such offences are determined by the regulatory framework and can vary based on the nature and extent of the non-compliance. Ensuring adherence to these regulations is critical to maintaining the safety standards required in civil aviation.
