The FAA found out that some tubes inside certain Boeing airplanes were put in the wrong way when the planes were changed from carrying people to carrying packages. They want to check these tubes and fix any problems to make sure the planes stay safe in the sky.
Summary AI
The Federal Aviation Administration (FAA) proposes a new airworthiness directive (AD) for certain Boeing 767-300 series airplanes converted from passenger to freighter. This proposed AD is due to improperly installed pitot-static tubing in the plane's equipment center, which could lead to system malfunctions. It would require a visual inspection of certain tubes and hoses to check for issues and corrective actions if necessary. The FAA is seeking public comments on this proposal by January 31, 2025.
Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767-300 series airplanes modified by a certain supplemental type certificate (STC). This proposed AD was prompted by a discovery that certain pitot-static tubing of the first officer's pitot-static system was installed incorrectly in the main and mid equipment center during the airplane conversion from passenger to freighter. This proposed AD would require a visual inspection of certain pitot-static rigid tubes and flexible hoses to determine whether low points exist, and if necessary, related investigative and corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

The Federal Aviation Administration (FAA) proposes introducing a new airworthiness directive (AD) for specific Boeing 767-300 airplanes that have been converted from passenger use to freighters. This proposal comes in response to issues discovered in the pitot-static tubing systems, which are crucial for various flight measurements. If installed incorrectly, these tubes posethe risk of malfunction, potentially impacting flight safety. The directive would require thorough inspections and, if needed, corrective actions to ensure the systems are functioning properly. The FAA invites public comments on this proposal, with a deadline for submission by January 31, 2025.
Significant Issues and Concerns
One significant issue with the document is its use of highly technical terms such as "pitot-static tubing" and "Supplemental Type Certificate (STC)," which may not be easily understood by those unfamiliar with aviation specifics. The document's reliance on specialized jargon might limit accessibility for the general public. Moreover, key materials and references are noted under the "Material Incorporated by Reference" section, presenting potential transparency challenges due to the possibly limited availability of these resources for non-professionals.
Additionally, the document lacks a comprehensive breakdown of the compliance costs. This omission can obscure the economic impact on affected aircraft operators, particularly those managing smaller fleets. The FAA asserts that there will be no significant economic impact on small entities, but the absence of a detailed economic analysis raises concerns about oversight in this area.
Public Impact
For the broader public, this proposal underscores the FAA's commitment to maintaining safety in air travel, particularly as aircraft go through modifications that can introduce new risks. The directive aims to mitigate potential issues before they affect passengers or cargo operations. However, understanding the specifics and ramifications of the directive might prove challenging for people lacking specialized aviation knowledge.
Stakeholder Impact
For stakeholders directly involved in the aviation industry, particularly Boeing 767-300 operators, this directive represents an increased regulatory requirement that would necessitate action and potentially incur costs related to the inspections and any ensuing repairs. While the document indicates a proactive approach to ensuring safety, aircraft operators might face logistical and financial challenges associated with compliance.
On the upside, ensuring that pitot-static systems are correctly installed and maintained can help avoid costly errors during flight operations, thereby enhancing the reliability of aircraft performance. Yet, this requirement could unequally affect operators depending on the number of aircraft they own and the complexity of required corrections.
The international references and certifications mentioned in the document may lead to confusion unless adequately contextualized. The proposal includes standards from various international aviation authorities, signaling collaboration but potentially resulting in misunderstandings regarding equivalences with U.S. regulations.
Overall, while the directive is aimed at enhancing aviation safety, the document's complexities and lack of detailed economic impact assessment may hinder public understanding and raise concerns among stakeholders about implementation and compliance requirements.
Issues
• The document uses technical aviation jargon, such as 'pitot-static tubing' and 'SUPPLEMENTAL TYPE CERTIFICATE (STC),' which may not be easily understood by individuals who are not specialized in the field of aviation.
• The section labeled 'Material Incorporated by Reference Under 1 CFR Part 51' refers to specific materials and documentation that might not be easily accessible to the general public, which could limit transparency.
• The FAA's estimation of compliance costs is not detailed in the document, potentially obscuring the economic impact of the proposed airworthiness directive on affected parties.
• There is a lack of detailed explanation on how the proposed AD addresses the 'unsafe condition' beyond inspection and corrective action mandates, which may leave stakeholders uncertain about the overall safety enhancement achieved.
• The document refers to international aviation authorities and certifications without providing adequate context on their relevance or equivalency to US standards, which may lead to confusion.
• There is no specific economic impact analysis provided for small entities, even though it states that the AD would not have a significant economic impact, which might raise concerns of oversight in evaluating small business effects.
• Some sentences, particularly those explaining technical procedures or legal implications, are long and complex, potentially reducing readability and understanding for a general audience.
