AD/BELL 206/117 Amdt 1 - Bogus Main Rotor Blades

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, govern civil aviation safety in Australia. A significant addition to these regulations was the incorporation of Airworthiness Directives (ADs), including AD/BELL 206/117, which specifically addresses the safety issue related to the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series helicopters. This directive was introduced to address the problem of counterfeit main rotor blades that have been resold with falsified component history cards, posing a significant risk to aviation safety. The objective of AD/BELL 206/117 is to ensure that identified blades are removed from service to mitigate safety risks associated with the use of these compromised components.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, mandates airworthiness directives that apply to certain Bell Helicopter Textron Canada (BHTC) and Agusta Bell 206 series helicopters, namely models 206A, 206B, 206L, 206L-1, and 206L-3. These regulations necessitate a visual inspection of the main rotor blades with specific part numbers and serial numbers listed in the directive. Operators of these models must remove from service the blades with the serial numbers identified to ensure compliance. The requirement applies to any operation of these helicopters after 11 December 1989, as stipulated in the amendment. The regulation’s scope is national, enforced under the Commonwealth of Australia’s Civil Aviation Safety Authority (CASA), ensuring adherence across all states and territories. There are no stated exclusions or exemptions in this directive, and the requirements extend through subordinate instruments as noted in FAA AD 89-22-01 R1.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, section 105, include an airworthiness directive (AD) issued by the Civil Aviation Safety Authority (CASA) concerning Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series helicopters. AD/BELL 206/117 Amendment 1 addresses the issue of bogus main rotor blades and their applicability to certain models, namely the 206A, 206B, 206L, 206L-1 and 206L-3. This directive mandates a visual inspection of specific main rotor blades, identified by their part numbers and serial numbers, and requires the removal of those blades from service that match the listed serial numbers. The directive was issued to address concerns about blades that had exceeded their fatigue life limit and were subsequently resold with falsified component history cards. The obligations imposed by this AD include conducting a thorough visual inspection of the specified main rotor blades on the mentioned helicopter models. Operators must ensure that the blades with the listed serial numbers are removed from service and not used further. This requirement applies to all operators of the affected helicopter models and must be complied with before any further flight after 11 December 1989. Compliance involves not only the inspection and identification of the specified blades but also the verification of the serial numbers against the list provided in the directive to ensure that the correct blades are removed from service. Failure to comply with the requirements set out in AD/BELL 206/117 Amendment 1 can result in serious consequences. The AD specifies that non-compliance may lead to civil penalties under section 135 of the Civil Aviation Act 1988, which can include fines and other sanctions. Additionally, operating a helicopter with non-compliant main rotor blades could be considered a breach of airworthiness regulations, potentially resulting in criminal charges for the operator or owner. The penalties for such breaches can be significant, reflecting the importance of ensuring the safety of air operations by adhering to CASA directives.
