The FAA wants to make sure certain airplanes are safe by checking some hoses to make sure they aren't rubbing too much, which could make them break. People have until February 20, 2025, to give their thoughts about this plan.
Summary AI
The Federal Aviation Administration (FAA) has proposed a new rule regarding Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes due to reports of hydraulic pressure hoses chafing against the aircraft structure, which could cause hydraulic system failures. The rule requires inspections and corrective actions to prevent this issue, and comments on the proposal are open until February 20, 2025. The rule aims to ensure the continued safety of the aircraft by preventing potential hydraulic system leaks and failures that could impact the airplane's operational capabilities.
Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports of engine-driven pump hydraulic pressure hoses for hydraulic systems number 1 and 2 chafing against the pylon in the aft equipment bay. This proposed AD would require an inspection of the engine-driven pump pressure hoses for any damage and minimum clearance between the engine-driven pump hydraulic pressure hose and case drain, suction pressure hose, and surrounding pylon structure; and corrective actions if necessary. The FAA is proposing this AD to address the unsafe condition on these products.

Summary of the Document
The Federal Aviation Administration (FAA) is proposing a new rule regarding certain Bombardier airplane models due to safety concerns. The rule specifically targets Model BD-700-1A10 and BD-700-1A11 airplanes. Reports have revealed that hydraulic pressure hoses are prone to chafing against parts of the aircraft, which poses a risk of hydraulic system failures. To address this, the rule mandates inspection and any necessary corrective actions to prevent such issues. Public comments on the proposal are welcomed until February 20, 2025.
Key Issues and Concerns
There are several issues noted within the proposal:
Cost Estimation: The proposal does not adequately specify the estimated costs for any necessary fixes that operators may have to undertake, making it challenging to gauge the financial implications for those who own or operate these aircraft.
Complexity in Submitting Comments: The document outlines multiple ways to submit comments, including via mail, fax, and online, which could be potentially overwhelming for individuals not familiar with regulatory processes.
Technical Language: The use of technical terms and references to specific service bulletins might be inaccessible for those without a background in aviation, limiting broader public understanding and engagement.
Warranty Information: There's mention of possible warranty coverage that could reduce costs but lacks comprehensive details about when or how this coverage applies, which might be crucial for operators.
Service Bulletins Date Confusion: The document refers to several service bulletins issued on the same date without additional distinctions, possibly leading to confusion.
Timeline Clarity: The requirement to conduct inspections within a 500-flight-hour period or within 18 months could be perplexing for those unsure which takes precedence; however, it is noted to be "whichever occurs first."
Confidentiality Instructions: Directions for handling confidential business information are stated, but terms like "PROPIN" might not be clear to all relevant parties who might handle these documents.
Broad Public Impact
The general public primarily benefits from increased safety in air travel. By addressing these issues with Bombardier aircraft, the FAA aims to prevent potential accidents arising from hydraulic system failures. This regulatory intervention underscores efforts to maintain the reliability and safety of flying, thereby fostering public confidence in air travel.
Stakeholder Impact
For aircraft operators, this rule represents an additional maintenance and compliance burden but also provides guidance to prevent potentially catastrophic failures. While the inspections might incur costs, the possible warranty coverage could mitigate some financial impacts.
Manufacturers, such as Bombardier, might experience increased demands for assistance and parts, especially if current or potential issues necessitate more comprehensive support for affected airplane models.
Aviation safety professionals might view this positively, as it reflects proactive measures in safeguarding aircraft operations. However, more clarity and communication, especially concerning the technical aspects and costs, could improve stakeholder engagement and compliance.
The proposal, overall, strikes a balance between significant safety assurances and the manageable, albeit unspecified, cost to aircraft operators. Stakeholders stand to benefit from clarity, consistent communication, and potential cost-sharing solutions such as warranties.
Issues
• The document does not provide specific cost estimates for necessary on-condition actions for affected airplanes, making it difficult to assess the potential financial impact on operators.
• The text describing the submission of comments includes many contact details and methods, which might be confusing for some users, particularly those unfamiliar with the regulatory process.
• The use of technical terminology and references to specific service bulletins without providing additional context or explanations may be difficult for individuals without specialized knowledge in aviation systems.
• There is mention of warranty coverage potentially impacting costs but lacks specific details or conditions under which the warranty would apply.
• The document references multiple service bulletins with the same date. This could lead to confusion without additional distinguishing information.
• The requirement to inspect within 500 flight hours or 18 months might be unclear as to which should take precedence if they do not occur simultaneously, though it is indicated to be 'whichever occurs first'.
• Instructions related to Commercial Business Information (CBI) refer to marking documents with 'PROPIN', which might not be clear to all stakeholders who need guidance on this matter.
