The FAA wants to make sure Airbus planes are safe by fixing a problem with the landing gear, like replacing some parts to keep them from breaking. People who fly or work with these planes can tell the FAA what they think about this plan until April 7, 2025.
Summary AI
The Federal Aviation Administration (FAA) has proposed a new rule for Airbus SAS Model A350-941 airplanes after discovering anodic burns on the landing gear axles. This rule requires replacing the affected axles and stopping the use of parts with these defects to prevent potential structural failures. Public comments on this proposal must be submitted by April 7, 2025. This regulation aligns with a European Union Aviation Safety Agency directive and aims to ensure the safe operation of these airplanes.
Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 airplanes. This proposed AD was prompted by an inspection that found several anodic burns on the main landing gear (MLG) bogie beam axles following a high velocity oxygen- fuel (HVOF) stripping process. This proposed AD would require replacement of affected MLG bogie beam axles, and would also prohibit the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

Summary of the Proposed Rule
In February 2025, the Federal Aviation Administration (FAA) introduced a proposed rule focused on enhancing the safety of Airbus SAS Model A350-941 airplanes. The proposal arose after inspections revealed anodic burns on certain critical components of the aircraft's main landing gear. Specifically, these burns were observed on the bogie beam axles—a crucial part of the landing gear—following a particular stripping process. The proposed rule mandates the replacement of the affected parts and prohibits the future use of such defective components. This action aligns with a similar directive from the European Union Aviation Safety Agency (EASA), ensuring international consistency in aviation safety standards.
Significant Issues and Concerns
Several issues arise from the proposed rule that may concern stakeholders:
Clarity and Accessibility: The document outlines specific directives and procedures without directly linking the Service Bulletin that contains detailed replacement instructions. This absence could complicate the understanding and compliance for operators who need to adhere to the directive.
Complex Language: The section that explains compliance requirements uses technical jargon that may not be easily understood by a layperson. This complexity can make it challenging for individuals unfamiliar with legal or aviation terminology to fully grasp what is required.
Economic Impact: The proposal fails to provide a clear cost estimate for the necessary replacements, making it difficult for airline operators to evaluate the financial implications.
Alternative Compliance Procedures: Details about alternative methods for compliance appear complex. Simplifying these instructions would aid those needing to understand procedural alternatives.
Material Access: There is an inherent assumption that all relevant parties will have seamless access to required materials, which may not hold true for smaller operators or those less versed in regulatory navigation.
Handling of Confidential Information: The section on dealing with confidential business information may confuse some due to its detailed explanation of legal exemptions and submission processes without a clear guide.
Impact on the Public and Stakeholders
Broadly, the proposed rule aims to ensure the continued safety of air travel by addressing potential weaknesses in aircraft components. For the general public, this contributes to the confidence in air travel safety and regulatory vigilance over aircraft operation.
For specific stakeholders such as airlines, the proposed rule might result in both operational and financial impacts. Airlines would need to comply with the directive by replacing defective parts, which, absent specific cost estimates, makes financial planning challenging. There is a potential economic burden, particularly on smaller carriers, due to the vague financial implications regarding compliance.
Conversely, the proposed rule benefits stakeholders by enhancing safety protocols, potentially reducing the risk of landing gear failure that could lead to accidents involving costly damages or injuries. The rule also supports alignment with international safety standards, facilitating smoother operations across borders for airlines that operate internationally.
In summary, while the FAA's proposed rule is aligned with safety advancements in aviation, it should aim for clearer communication and transparency regarding compliance procedures, costs, and access to necessary materials to support stakeholders effectively.
Issues
• The document repeatedly mentions directives and procedures but does not provide a direct link to the replacement instructions in the Service Bulletin (SB). This could create confusion for operators needing to comply with the AD.
• The language used in the 'Explanation of Required Compliance Information' section is complex and may be difficult for laypersons to understand, especially regarding the incorporation by reference of the EASA AD.
• The document does not provide any specific cost estimates for the replacement of the MLG bogie beam axles, which makes it difficult to assess the financial impact on airlines.
• The language in the section regarding 'Alternative Methods of Compliance (AMOCs)' might be seen as complex due to the procedural details, and could benefit from a simplified explanation.
• There is an assumption that all interested parties will have access to the necessary material through their usual business methods without considering potential barriers for smaller operators or those less familiar with regulatory processes.
• The section discussing 'Confidential Business Information' (CBI) might confuse some readers, as it details FOIA exemptions and proper designation of sensitive information without a direct guide on how to submit such information.
