The airplane company found a problem with the computer software that helps the plane fly and land safely, so they are asking people to update it to make sure it's safe. The company wants people to share their thoughts about this before they make it a rule, but they don't clearly explain how to do it.
Summary AI
The Federal Aviation Administration (FAA) is proposing a new airworthiness directive for specific Airbus Canada airplanes due to software issues in their flight control systems. The directive requires a software update to ensure safe flight and landing by correcting problems with the primary flight control computer and remote electronics unit. The FAA invites public comments on this proposal, which must be submitted by April 12, 2021, and will consider any feedback before finalizing the rule. This proposal is based on a related Canadian directive addressing these safety concerns.
Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by reports of deficiencies in the primary flight control computer (PFCC) and remote electronics unit (REU) software. This proposed AD would require installation of a software update to correct deficiencies in the PFCC and REU software, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

General Summary
The Federal Aviation Administration (FAA), a division of the Department of Transportation (DOT), has put forth a proposal for a new airworthiness directive. This proposed directive targets specific models of airplanes from Airbus Canada, highlighting a critical need for a software update. The primary motivation behind this directive is to address deficiencies identified in the flight control systems of these airplanes, specifically the primary flight control computer (PFCC) and remote electronics unit (REU). The update is crucial to maintaining safe flight operations and ensuring successful landings. Moreover, the FAA is currently seeking public input on this proposed directive, which is based on a similar Canadian directive. Comments and feedback from the public are invited and must be submitted by April 12, 2021.
Significant Issues and Concerns
The document lists several technical details, particularly regarding compliance requirements and software update procedures. One noticeable issue is the document's reliance on specialized language that might not be easily understood by those outside of the avionics or aviation regulation fields. Such complexity may hinder broader public understanding, including interested parties who may wish to comment on the proposal.
Furthermore, while it is mentioned that some costs associated with these updates might be covered under warranty, the document does not specify precisely which expenses or under what conditions these warranties would apply. This lack of clarity could lead to uncertainties and confusion for the stakeholders involved, particularly for airline operators responsible for implementing these updates.
Impact on the Public
For the general public, especially those who frequently travel by air, this proposed directive indirectly aids in enhancing the overall safety of air travel. While passengers may not interact directly with airworthiness directives, the safety measures they enforce ensure safer flights for all.
However, the method for public engagement, including the submission of comments, comes across as somewhat cumbersome. The procedural intricacies specified for participation might dissuade individuals from providing feedback, thereby limiting public involvement in the regulatory process.
Impact on Specific Stakeholders
Airline Operators and Aircraft Owners: These stakeholders bear the brunt of implementing the directive. If the warranty does not cover specific costs, they will incur expenses that could impact operational budgets. However, compliance is mandatory to ensure continued service operations.
Avionics Engineers and Technicians: For these professionals, the directive emphasizes the importance of understanding and implementing software updates on safety-critical systems. While this directive underscores their expertise's value, it also places a significant responsibility on them to ensure these updates are performed flawlessly.
Regulatory and Aviation Authorities: Authorities benefit from such directives as they establish a framework to systematically address compliance and enhance safety. The FAA’s collaboration with international aviation bodies, such as Transport Canada, reflects an ongoing mutual effort to uphold aviation safety standards across borders.
In conclusion, while the directive marks a significant step towards reinforcing aviation safety, especially concerning software-dependent systems, its successful implementation hinges on clarified processes and effective communication with all relevant stakeholders.
Issues
• The document mentions that some or all of the costs may be covered under warranty, but it does not specify which costs and under what conditions they will be covered, leading to uncertainty regarding financial implications.
• The language in the document is highly technical, particularly regarding the software updates required for the primary flight control computer and remote electronics unit, which may not be easily understood by those not versed in avionics or aviation regulations.
• The document refers to compliance times and specific paragraphs (h)(2)(i) through (iii) for actions without clearly consolidating this information for easier understanding by readers.
• The document details methods to submit comments and examine the AD docket but does not provide a streamlined or simplified way to access this information, potentially hindering public engagement.
