The FAA is changing the rules for checking certain Airbus helicopters to keep them safe, making sure their spinny tail parts get checked and fixed often so nothing breaks and flying stays safe.
Summary AI
The Federal Aviation Administration (FAA) has issued a new rule to replace a previous Airworthiness Directive (AD) related to certain models of Airbus helicopters. The updated AD requires consistent inspections and replacements of parts within the tail rotor components of these helicopters to address safety concerns related to potential damage observed in the flapping hinge link. This new directive aims to prevent potential helicopter control issues by expanding inspection requirements and introducing corrective measures if irregularities like cracking or spalling are found. The rule takes effect on April 1, 2021, and applies to specific Airbus helicopter models.
Abstract
The FAA is superseding Airworthiness Directive (AD) 2018-05- 09, which applied to all Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. AD 2018-05-09 required inspecting the tail rotor (T/R) flapping hinge link (hinge) and reporting the results. This AD requires repetitive inspections of the spindle bolts and the inner ring and needle bearings of each flapping hinge, corrective actions if necessary, and repetitive replacements of affected flapping hinge components, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. Replacement of all affected flapping hinge components on each flapping hinge is terminating action for the repetitive inspections. This AD also expands the applicability. This AD was prompted by a report of a damaged flapping hinge on a T/R blade. The FAA is issuing this AD to address the unsafe condition on these products.

Overview
The Federal Aviation Administration (FAA) has enacted a new rule, replacing a previous Airworthiness Directive (AD) concerning several Airbus Helicopters models. This updated directive applies to the AS332C, AS332C1, AS332L, and AS332L1 helicopters, along with the SA330J model. The primary focus is on improving safety by implementing regular inspections and replacements of specific tail rotor components to address potential damage issues, notably within the flapping hinge link. The rule aims to preempt possible safety risks such as unbalanced tail rotors that could lead to critical control failures.
Significant Issues and Concerns
One notable issue with the document is the lack of detail regarding compliance costs. Without clear information on the financial implications, it is challenging for stakeholders, especially smaller operators, to gauge the economic impact. The document also lacks a detailed explanation for exceptions to the European Union Aviation Safety Agency (EASA) AD, which could lead to confusion among those affected. The complex technical language and reliance on external resources, like websites and additional documents, might hinder understanding for individuals without a deep aviation or legal background. Additionally, the guidance on corrective actions and alternative compliance methods (AMOCs) might be seen as vague, requiring further clarification to ensure proper adherence.
Public Impact
Broadly, the directive is poised to enhance flight safety by addressing a potentially dangerous condition in specific helicopter models. The public benefits by minimizing the risk of incidents caused by mechanical failures, contributing to safer air travels overall. For communities near helicopter operation zones, this rule could decrease the risk of accidents, which might have wider implications for local safety.
Stakeholder Impact
Helicopter Operators and Aviation Industry:
Operators of the specified helicopter models will face increased operational scrutiny and potentially more frequent maintenance, influencing their day-to-day operations. Although this might result in increased maintenance costs and temporary operational downtime, the long-term benefits of improved safety and reduced accident risks could outweigh initial inconveniences.
Airbus Helicopters:
As the manufacturer, Airbus may receive feedback requiring further design improvements or revised maintenance documentation to simplify the compliance process. They might also need to increase customer support efforts to assist operators in meeting the new directive’s requirements.
Aviation Safety Regulators and Compliance Officers:
For regulators, the directive will require careful monitoring and enforcement to ensure compliance. Compliance officers might need additional guidance or resources to assist and oversee helicopter operators effectively.
By addressing safety risks preemptively, this FAA rule reinforces aviation standards and upholds public confidence in air travel. However, stakeholders must navigate the operational and economic challenges brought about by these compliance requirements efficiently.
Issues
• The document does not disclose any specific costs for compliance, making it difficult to assess potential economic impact on stakeholders.
• There is no detailed explanation of why the exceptions to EASA AD 2020-0086 are necessary, which could lead to confusion.
• The language used in describing the technical requirements and exceptions is quite technical and may not be easily comprehensible to all stakeholders without a technical background.
• The document references several external documents and websites, increasing dependency on external sources for complete understanding of the regulation.
• The document does not contain a breakdown of potential indirect costs, such as impacts on operational downtime for affected helicopter operators.
• The language specifying 'corrective actions if necessary' and 'if requested' in terms of AMOCs (Alternative Methods of Compliance) is somewhat ambiguous without clearer guidance on what qualifies as necessary or eligible for these exceptions.
