The FAA wants to make sure Boeing 757 airplanes are safer by fixing some parts so that they don't have to keep checking them over and over. They are asking people to tell them what they think about this idea until the end of March 2025.
Summary AI
The Federal Aviation Administration (FAA) is proposing a new set of rules to improve the safety of Boeing 757 airplanes by modifying specific parts. This proposal aims to replace an existing airworthiness directive from 2019, which involved checking and inspecting certain components due to a previous failure that could affect the plane’s control. The updated rules would require modifying the attachment lug of the aileron trim actuator and related components, which will end the need for repetitive checks and inspections. The FAA is inviting comments on this proposal until March 31, 2025, to ensure all potential safety concerns are addressed.
Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2019-12-13, which applies to all The Boeing Company Model 757 airplanes. AD 2019-12-13 requires repetitive checks of the aileron trim actuator bearing for free rotation, repetitive detailed inspections of the aileron trim actuator attachment lug for damage and cracking, and applicable on-condition actions. Since the FAA issued AD 2019-12-13, the FAA has determined that a modification must be done to address the unsafe condition. This proposed AD would continue to require the actions in AD 2019-12-13. This proposed AD would also require for certain airplanes changing the lateral control box support assembly and installing an aileron trim actuator bracket, and for certain other airplanes replacing the existing actuator lateral control fitting with an aileron trim actuator bracket, which terminates the repetitive checks and inspections. The FAA is proposing this AD to address the unsafe condition on these products.

General Summary
The Federal Aviation Administration (FAA) has issued a proposed rule that aims to update existing safety protocols for Boeing 757 airplanes. This proposed rule would modify a previously issued Airworthiness Directive (AD) from 2019, which focused on inspections and checks to ensure safe functioning of the aileron trim actuator—a crucial component affecting an aircraft's lateral control. The newly proposed regulations would mandate structural modifications, which are designed to alleviate ongoing concerns, thus eliminating the need for repetitive checks and inspections. The FAA is actively seeking public input on this proposal until March 31, 2025.
Significant Issues or Concerns
The document contains complex legal and technical language, which might pose comprehension challenges for individuals who do not have a background in aviation or legal matters. Additionally, while providing a detailed scope of the required modifications and their implications, the document lacks specific cost estimates for the necessary repairs on an as-needed basis. This lack of clarity could lead to unpredictability in compliance costs for airlines or aircraft owners. Furthermore, while the document briefly mentions that the economic impact on small entities would not be significant, it offers no elaborate analysis or supporting data to substantiate this claim, potentially leaving smaller stakeholders without clear expectations about their financial obligations.
Broad Public Impact
For the general public, the proposed rule is primarily about enhancing air safety for Boeing 757 airplanes, which are recognized globally for their use in both passenger and cargo transport. By targeting specific technical issues, the FAA aims to maintain high safety standards, ensuring that air travel remains reliable and secure for everyone. This focus on preemptive modifications rather than repetitive inspections aims to streamline maintenance processes, ideally leading to fewer interruptions and more consistent flight operations.
Impact on Specific Stakeholders
The proposal could have varying effects on different stakeholders. Airlines operating Boeing 757s may face initial increased costs due to the required modifications. However, these upfront investments are expected to reduce long-term maintenance disruptions, potentially leading to greater operational efficiency and safety. Smaller airlines or entities, who might not have immediate access to resources for compliance, could find themselves at a disadvantage due to unspecified costs and requirements for acquiring necessary materials. On the positive side, these regulations, once implemented, could enhance the overall market confidence in the safety of Boeing 757 aircraft. Aviation safety engineers and other specialists in the field may find increased utility in their expertise as they engage in the required modifications.
In sum, while the FAA's proposed rule reflects a decisive step towards maintaining and enhancing aviation safety, it raises several economic and practical queries that need addressing to ensure all stakeholders are adequately prepared and informed.
Issues
• The document contains complex legal and technical language that might be difficult for laypersons to understand.
• The document lacks specific cost estimates for the on-condition repair, which raises concerns about potential unpredictability in compliance costs.
• There is no clear explanation of the economic impact on small entities, other than a brief mention that it would not be significant.
• Limited details are provided on how access to material necessary for compliance is managed, particularly for parties without regular access through 'normal course of business.'
