The FAA found a mistake in the instructions for fixing a part on some Airbus airplanes, which could cause navigation problems, so they want to fix it by tightening some nuts correctly and stopping using the wrong instructions.
Summary AI
The Federal Aviation Administration (FAA) has issued a final rule for certain Airbus SAS airplanes due to an error found in the maintenance manual. The document reports that an incorrect torque value for the nuts attaching a pitot probe could lead to faulty readings affecting airplane navigation. As a result, re-torqueing of these nuts is required, and the use of the erroneous manual task is prohibited. The rule, which impacts 112 airplanes within the U.S., becomes effective on January 29, 2021, and comments on the rule are welcome until March 1, 2021.
Abstract
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200, -200 Freighter, -300, -800, and -900 series airplanes; Model A340-200 and -300 series airplanes; and Model A340-541 and A340-642 airplanes. This AD was prompted by a report that an erroneous torque value for the attachment nuts to install a pitot probe was included in the affected Aircraft Maintenance Manual (AMM) task. This AD requires re-torqueing the attachment nuts of each affected part. In addition, this AD prohibits the use of the affected AMM task, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The document is a new airworthiness directive (AD) issued by the Federal Aviation Administration (FAA) concerning Airbus SAS airplanes. Specifically, it addresses an issue where the maintenance manual contained incorrect torque values for the nuts attaching a pitot probe. This inaccuracy could lead to erroneous readings, ultimately affecting an airplane's navigation system. To mitigate this risk, the FAA mandates re-torqueing the affected nuts and prohibits using the flawed manual task. This directive targets 112 airplanes registered in the United States and becomes effective January 29, 2021. The public is invited to comment on this directive until March 1, 2021.
General Overview
The essence of the document is to ensure the safety of certain Airbus airplanes by correcting a maintenance procedure error. The problem, if left unchecked, could result in reduced control of an aircraft by affecting its navigation system. This action underscores the importance of precise maintenance guidelines to aviation safety, thereby prompting the FAA to issue this directive mandating specific corrective measures.
Significant Issues and Concerns
Several concerns arise out of this directive. Firstly, the document is highly technical. It contains numerous acronyms and references, like ADs and other regulatory documents, which might be difficult for individuals without a background in aviation to fully understand. This complexity might create challenges in comprehending the requirements and implications of the directive.
Furthermore, the document provides multiple methods and addresses for submitting comments. This could potentially confuse stakeholders who wish to participate in the public comment process, leading to fewer engagements or misdirected submissions.
Another notable issue is the directive's reliance on a European counterpart, the EASA AD 2020-0279. While it specifies compliance with this European directive, it does not explicitly clarify how differences, if any, between the EASA and FAA requirements will be managed. This could create ambiguity for operators who need to satisfy both U.S. and European regulatory frameworks.
Additionally, details labeled as "Required for Compliance (RC)" may not be easily identifiable or understood by all users. This could potentially lead to compliance issues if operators fail to recognize the importance of these specific instructions.
Impact on the Public
Broadly, this directive aims to enhance passenger safety by addressing an identified flaw in aircraft maintenance procedures that could affect flight safety. The public, particularly those traveling on affected aircraft, might experience increased confidence knowing that airline operators must ensure their airplanes meet the required safety standards.
For stakeholders, namely aircraft operators, the directive represents an added operational requirement. Adhering to this directive will necessitate additional time and resources to re-torque affected nuts and suppress usage of the erroneous maintenance task. These requirements might impose additional costs or operational delays, particularly if aircraft are temporarily grounded for compliance purposes.
Impact on Specific Stakeholders
Airline operators might view this directive negatively because of the operational disruptions and costs involved in implementing the required changes. However, the long-term benefits of maintaining high safety standards likely outweigh these initial inconveniences.
Manufacturers and maintenance organizations will also need to update their processes and documentation to align with the directive. This might initially be seen as an administrative burden, but it will ultimately ensure the accuracy and reliability of maintenance practices, which may positively impact safety records and reputations.
On the other hand, regulatory compliance brings about enhanced safety, potentially reducing liability for accidents related to maintenance errors. This could foster goodwill and trust among passengers, stakeholders, and regulatory bodies, promoting the airline's commitment to safety.
In summary, while the directive may pose some initial challenges, its primary goal is to safeguard passengers and ensure the continued safe function of affected Airbus aircraft.
Issues
• The document is highly technical and may be difficult for individuals without a background in aviation regulation to understand. It uses many acronyms and references to specific ADs and service information, which could be clarified or simplified.
• The process for commenting on the airworthiness directive might be seen as complex, particularly the various methods and addresses for submitting comments, which may confuse stakeholders.
• The document refers to European Union Aviation Safety Agency (EASA) AD 2020-0279, specifying compliance with the EASA's directive but does not clearly explain how differences between it and FAA requirements will be handled, potentially leading to ambiguity.
• Important regulatory compliance details, labeled as 'Required for Compliance (RC),' might not be easily identified by all users, leading to potential compliance issues.
