AD/R22/26 - Clutch Actuator Overtravel Limit Switch

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, is a comprehensive regulatory framework governing all aspects of civil aviation in Australia. A specific focus within this Act is the regulation of airworthiness directives, such as the one pertaining to Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, as seen in the amendment AD/BELL 206/117 Amendment 1. This amendment, introduced to address the identified problem of falsified component history cards and the associated safety risks, mandates the visual inspection and removal from service of certain main rotor blades on specified helicopter models. The policy objective here is to ensure the safety and reliability of civil aviation operations by enforcing stringent airworthiness standards. The Civil Aviation Safety Authority, through the issuance of this directive, seeks to mitigate potential risks associated with the use of rotor blades that have exceeded their fatigue life limits and were resold with falsified documentation. This amendment underscores the importance of adhering to regulatory standards to maintain the highest levels of aviation safety.

Scope and Application

The Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998, Part 39, mandates specific airworthiness directives for certain helicopter models manufactured by Bell Helicopter Textron Canada (BHTC). Specifically, Airworthiness Directive AD/BELL 206/117 Amendment 1 pertains to the Bell 206 and Agusta Bell 206 series helicopters, focusing on the visual inspection and removal from service of specific main rotor blades. This directive applies to the models 206A, 206B, 206L, 206L-1, and 206L-3, requiring operators to inspect blades with particular part numbers and serial numbers and remove those with specified serial numbers from service. The directive necessitates compliance before further flight after 11 December 1989, addressing safety concerns related to the fatigue life limit of these components, which were resold with falsified documentation. The directive's applicability is national, enforced by CASA, and extends to all helicopters of the specified models operating within Australia.

Key Provisions

The Civil Aviation Regulations 1998, specifically in PART 39 - 105 under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, address the safety concerns associated with the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters. This legislation mandates a detailed visual inspection and removal from service of specific main rotor blades (section 2/90 TX). The applicable models include 206A, 206B, 206L, 206L-1, and 206L-3. For models 206A and 206B, the blades to be inspected are P/N 206-015-001-001, 206-015-001-103, 206-015-001-105, and 206-010-200-033, with specific serial numbers listed for removal. Similarly, for models 206L, 206L-1, and 206L-3, the blades P/N 206-015-001-001, 206-015-001-103, 206-015-001-105, and 206-010-200-033, with their respective serial numbers, must also be inspected and removed if they fall within the specified serial numbers. This directive ensures that blades that have reached their fatigue life limit and were resold with falsified component history cards are identified and removed from service to maintain safety standards. The obligations imposed by this legislation are clear and directive. Operators of the specified Bell Helicopter models must visually inspect the main rotor blades and remove those with the listed serial numbers from service. This requirement is mandatory and must be fulfilled before any further flight after 11 December 1989. The directive underscores the importance of adhering to the specified serial numbers and ensuring that only the blades with these numbers are removed from service. Operators must ensure that all inspections and removals are carried out in accordance with the directive to comply with aviation safety regulations. Failure to comply with the requirements outlined in the Civil Aviation Regulations 1998 can result in significant legal consequences. Any breach of these safety directives can be considered an offence under the legislation, potentially leading to enforcement actions by CASA. The penalties for non-compliance can include substantial fines and, in severe cases, criminal charges against the responsible individuals or entities. The exact penalties are determined by the nature and severity of the breach, but they can be severe, reflecting the critical importance of adhering to these safety directives to ensure the safety of all involved in aviation operations.
