The FAA wants to make sure certain Boeing planes are safe by checking for cracks, kind of like checking a toy to make sure it isn't broken. They're asking people to share their thoughts about this plan by the end of May 2025.
Summary AI
The Federal Aviation Administration (FAA) is proposing a new rule to inspect certain Boeing 767 airplanes for cracks in specific areas, due to a discovered defect at a fastener hole. This rule, part of an Airworthiness Directive (AD), requires owners to conduct inspections and make any necessary repairs to avoid compromising the planes' structural integrity. The rule aims to ensure safety by addressing potential issues before they become serious. Comments on this proposal are invited until May 27, 2025.
Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. This proposed AD was prompted by discovery of a crack at one of the forward lower fastener holes, outside of the underwing longeron (UWL) following replacement of a cracked UWL fitting. This proposed AD would require performing an open hole high frequency eddy current (HFEC) inspection for cracks of the fastener holes common to the UWL fitting, upper drag splice angle, and lower drag splice angle, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

Summary of the Proposed Rulemaking
In the Federal Register, the Federal Aviation Administration (FAA) has published a notice proposing a new Airworthiness Directive (AD) focusing on specific models of Boeing 767 airplanes. This initiative responds to a discovered crack at a fastener hole that could potentially endanger structural integrity. The proposed AD entails conducting inspections and executing repairs if needed to mitigate risks associated with undetected damages. Stakeholders, including aircraft operators and aviation maintenance organizations, are encouraged to submit their feedback on this proposed rule by May 27, 2025.
Significant Issues and Concerns
While the proposal is essential for ensuring flight safety, several issues are evident. A notable concern is the absence of detailed cost estimates required to comply with the AD. Without this information, assessing the financial repercussions on airlines and other operators remains challenging. Furthermore, the proposal lacks specifics regarding how many airplanes might require additional actions based on inspection results, impeding a comprehensive economic impact analysis.
The document's language presents another hurdle. Technical jargon, such as "open hole high frequency eddy current (HFEC) inspection," might not be easily understood by individuals who are not experts in aviation engineering. Moreover, references to other documents like the Boeing Alert Requirements Bulletin, without summarizing their content, can complicate understanding of the required actions for those unfamiliar with these materials.
Additionally, despite the mention of the Regulatory Flexibility Act, the lack of a thorough analysis concerning the effects on small businesses seems like an oversight. This gap could mean insufficient consideration of how smaller aviation operators or maintenance firms might adapt to the proposed requirements.
Potential Impact on the Public
Broadly speaking, this proposed rule intends to uphold public safety by ensuring that structural defects on affected aircraft models are identified and rectified before they compromise airworthiness. This focus on proactive safety management can reassure passengers and the general public regarding the regulatory rigor maintaining airline safety standards.
Impact on Specific Stakeholders
For aircraft operators, particularly those with Boeing 767 models in their fleets, compliance with this directive would necessitate operational adjustments and possible financial implications. The potential costs and logistical burdens of additional inspections and repairs might impact larger fleets differently than smaller ones.
A positive impact lies in pre-empting catastrophic failures, reducing the risk of incidents that could lead to expensive litigations and public relations challenges. However, smaller businesses, including repair stations or independent maintenance providers, might face difficulties if the cost or complexity of compliance exceeds their capacities, which could lead to negative economic impacts for some.
In conclusion, while the FAA's proposed directive stems from a necessity to address identified safety concerns, ensuring the feasibility and clarity of compliance actions remains essential to avoid undue strain, particularly on smaller stakeholders. The public's interest in flying safely, coupled with operational sustainability for airlines, should guide the finalization of these regulatory measures.
Issues
• The document lacks a clear estimate of the total costs to comply with the proposed AD, which makes it difficult to assess potential wasteful spending.
• There is no specific mention of how many airplanes might require the on-condition actions, making it hard to assess the potential economic impact.
• The language in some sections, such as the description of compliance and repair procedures in paragraphs (g) and (h), is dense and could be simplified for better understanding.
• The document frequently references other documents (e.g., Boeing Alert Requirements Bulletin) without detailing their content, making it difficult for the reader to fully understand the proposed actions without access to these materials.
• There is no detailed analysis of the potential impact on small businesses, despite the mention of the Regulatory Flexibility Act, which could be seen as an oversight.
• The document uses technical jargon, such as "open hole high frequency eddy current (HFEC) inspection," which could be challenging for laypersons to understand.
