The FAA wants some airplanes to get new parts to stop an important component from breaking. They're asking people to share their thoughts about this idea by April 12, 2021, so they can make sure airplanes stay safe.
Summary AI
The Federal Aviation Administration (FAA) has proposed a new airworthiness directive (AD) for specific Bombardier Model BD-100-1A10 airplanes due to DC motor pump (DCMP) failures that occurred during production flight tests. This proposed AD would require installing a redesigned DCMP electric motor assembly to prevent disconnection of electrical system generators caused by excessive voltage. Comments on this proposal are welcome until April 12, 2021, and the FAA aims to address the unsafe conditions in these airplanes with this directive.
Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This proposed AD was prompted by reports of DC motor pump (DCMP) failures during production flight tests. This proposed AD would require installing a redesigned DCMP electric motor assembly. The FAA is proposing this AD to address the unsafe condition on these products.

AnalysisAI
The document is a proposed rule from the Federal Aviation Administration (FAA), aiming to address a safety concern with certain Bombardier Model BD-100-1A10 airplanes. The FAA has observed failures in the DC motor pump (DCMP) during production flight tests, prompting the need for a new airworthiness directive (AD). This proposed AD requires installing a redesigned electric motor assembly for the DCMP to ensure the proper functioning of electrical system generators, which are vital for maintaining electrical power in the aircraft. Feedback on this proposal is solicited from stakeholders and the general public until April 12, 2021.
Summary of the Document
The proposed rule is a proactive effort to improve aviation safety by addressing a specific mechanical issue that could lead to significant failures during flight. Specifically, the DCMP issues could cause electrical system generators to disconnect during operation, which may result in a loss of electrical power. To mitigate this risk, the FAA mandates the installation of a redesigned motor assembly within a set compliance timeframe.
Significant Issues or Concerns
There are several notable issues within the document that merit attention:
Submission Process: The document allows for comment submission through both online and physical channels, which may cause delays or confusion. A push towards exclusively digital submissions could streamline feedback.
Technical Language: The document contains technical jargon and complex regulatory references, potentially making it difficult for the general public or non-specialists to fully understand the proposals and implications.
Feedback Guidance: While the FAA invites comments, the lack of specific guidance on what constitutes helpful feedback could result in unfocused or irrelevant submissions.
Financial Implications: The proposed directive might impose financial burdens on small aviation entities or private aircraft owners. The document does not address whether financial aid or support will be available to those burdened by the costs of compliance.
Design Details: The document does not provide details about the redesign, such as cost implications or improvements in the expected lifespan of the new assembly, which would be useful for stakeholders in understanding the necessity and potential benefits of the change.
Impact on the Public
Broadly, the proposed rule aims to enhance public safety by ensuring the reliability of aircraft systems. While this benefits the flying public by reducing the risk of in-flight electrical failures, the complexity of the document may limit broader public engagement. This may raise concerns about transparency and inclusiveness in regulatory processes.
Impact on Specific Stakeholders
For aircraft manufacturers, operators, and airlines, complying with the proposed AD might entail significant resources, both in terms of time and financial investment. However, the long-term benefits of enhanced safety and reliability could outweigh these initial costs. On the other hand, smaller operators or private owners might face substantial financial impacts without indications of forthcoming assistance or subsidies from the FAA.
While the intention of the proposed rule is rooted in safety, the communication and procedural aspects could be improved to foster greater understanding and engagement. The FAA's efforts to solicit public feedback are commendable, but clearer language and targeted guidance could enhance the quality of the feedback received.
Issues
• The document provides instructions for submitting comments both online and via mail, which might lead to delays and logistical issues. Streamlining for digital submissions could enhance efficiency.
• Language in the document is highly technical and may not be easily understood by individuals without expertise in aviation regulations, potentially limiting public engagement.
• The document encourages submission of 'views or arguments' on the proposal but lacks specific guidance on what constitutes relevant or useful comments, which may lead to a lack of focus in the feedback received.
• There is a potential issue for small aviation entities or private owners affected by the AD to bear financial burdens, with no indication of financial assistance or support from the FAA mentioned in the document.
• Details about the redesign of the DCMP electric motor assembly, such as costs and expected lifespan improvements, are not included, which could aid stakeholders in understanding the need and justification for the change.
