The government is telling airplane workers to make sure the rubber parts on the wings of some Bombardier planes are not loose or missing, so the planes fly safely and don't lose power. They have to check and fix these parts by January 23, 2025.
Summary AI
The Federal Aviation Administration (FAA) has issued a new rule requiring certain Bombardier Model BD-700-2A12 airplanes to be inspected due to issues with the pivot door pressure seals on the thrust reverser fixed structure. These seals have been reported as loose or missing, which could lead to engine thrust loss and affect the plane's performance, especially if one engine fails. The rule mandates inspecting and fixing these seals and performing a functional test on the thrust reversers by January 23, 2025. The aim is to ensure aviation safety by addressing this potentially unsafe condition.
Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was prompted by reports that the pivot door pressure seals on the thrust reverser fixed structure were found disbonded or missing on several airplanes. This AD requires inspecting the pivot door pressure seals and accomplishing applicable corrective actions. This AD also requires a functional test of the thrust reversers. The FAA is issuing this AD to address the unsafe condition on these products.

The Federal Aviation Administration (FAA) has issued a new rule concerning certain Bombardier Model BD-700-2A12 airplanes. This rule aims to address potentially unsafe conditions related to the pivot door pressure seals in the thrust reverser fixed structures of these aircraft. Reports have surfaced indicating that these seals are sometimes disbonded or missing. If not addressed, such issues could lead to loss of engine thrust and diminish aircraft performance, especially in scenarios where one engine is inoperative. To counter these risks, the FAA mandates inspections and corrective actions for these seals, along with a functional test of the thrust reversers, by January 23, 2025.
General Summary
The document outlines the FAA's concerns regarding safety issues arising from compromised pressure seals on some Bombardier planes. It requires inspections and maintenance to be completed by early 2025, emphasizing the need for proactive measures to ensure flight safety. This rule reflects the FAA's ongoing commitment to aviation safety, aligning with previous directives issued by Transport Canada.
Significant Issues or Concerns
Although the document provides a comprehensive description of the problem and necessary actions, it lacks specific information on the financial implications for affected airplane operators. The absence of detailed cost estimates could lead to unexpected expenses for airlines and other stakeholders. Furthermore, while the rule states no significant economic impact on small entities, it doesn't provide supporting data to substantiate this claim.
The complexity of the language may also pose challenges for comprehension among general audiences. References to technical documents and instructions could create barriers for stakeholders who don't have ready access to such materials. Additionally, the document doesn't mention potential penalties for non-compliance or delayed action, leaving a gap in the understanding of enforcement mechanisms.
Impact on the Public and Stakeholders
Broadly, this airworthiness directive serves to strengthen aviation safety, which benefits the flying public by potentially reducing the risk of incidents arising from mechanical failures. Airline passengers, crew members, and operators can expect enhanced safety measures as a result of these inspections and corrective actions.
For aircraft operators, the impact could be mixed. On the positive side, complying with this directive ensures that their aircraft meet safety standards, potentially preventing costly incidents. However, the lack of specific cost details may burden operators with unanticipated expenses. Airlines may face downtime as they conduct the requisite inspections and repairs, possibly affecting flight schedules and capacity.
Conclusion
The FAA's new rule for Bombardier airplanes is a step towards mitigating identified safety risks and maintaining high standards in aviation safety. While it is a necessary measure addressing critical safety concerns, it comes with challenges related to compliance costs, accessibility of information, and clarity on enforcement. Stakeholders will need to navigate these aspects to comply efficiently and effectively, ensuring their operations align with the FAA's directive. Overall, this rule underscores the importance of ongoing collaboration and communication between aviation authorities and operators to uphold safety and performance standards in the aviation industry.
Issues
• The document does not specify the exact cost of compliance for the affected 53 airplanes, although it mentions costs in a general sense. This may lead to uncertainty or unanticipated expenses for operators.
• While the document states that there is no significant economic impact on a substantial number of small entities, it does not provide specific analysis or data to support this claim.
• The language used in some sections, such as the authority and compliance sections, might be overly technical and difficult for a layperson to understand, potentially hindering comprehension.
• The document references multiple procedural documents, such as the Bombardier Service Bulletin, without summarizing their contents or impact, potentially making it difficult for stakeholders to assess the situation without accessing these documents.
• The document includes references to external resources and locations where materials can be accessed (e.g., FAA, NARA), which might not be easily accessible or convenient for all stakeholders, especially those who may not be located near these facilities.
• There is no section addressing what might occur if parties do not comply with the directive, or what penalties might entail if compliance is not fulfilled timely or properly.
• While there is an emphasis on the role of the International Validation Branch and Transport Canada, there is a lack of detailed explanation of how these entities will collaborate or their specific responsibilities in enforcing this airworthiness directive.
