The FAA is telling some airplane owners that they need to check certain parts of their planes because they might have cracks, which could be dangerous. They have to fix these cracks to keep the planes safe to fly.
Summary AI
The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for certain Boeing 737 series airplanes due to reports of cracks in specific areas of the aircraft, which could lead to serious safety issues. The directive mandates inspections and required actions to address these cracks, aiming to prevent problems like uncontrolled decompression and loss of structural integrity. The rule is effective from March 30, 2021, and requires compliance using methods approved by the FAA. The document also includes guidance on the costs involved and identifies how alternative methods of compliance can be approved.
Abstract
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD was prompted by reports of cracks in the bear strap from station (STA) 290 to STA 296, and between stringers S-8R and S-9R, sometimes common to fasteners in the gap cover and emanating from rough sanding marks found on the surface of the bear strap. This AD requires inspections of the fuselage skin and bear strap at the forward galley door between certain stations for cracks, and applicable on- condition actions. The FAA is issuing this AD to address the unsafe condition on these products.

The document from the Federal Register outlines an important new rule issued by the Federal Aviation Administration (FAA) aimed at addressing safety concerns related to certain Boeing 737 model airplanes. This rule, known as an airworthiness directive, specifically targets issues of cracking in parts of the aircraft that could lead to severe safety risks such as uncontrolled decompression or loss of structural integrity. The rule seeks to enforce several inspections and subsequent actions to mitigate these potential hazards.
General Summary
The core of the directive is to ensure that specific Boeing 737 models undergo mandatory inspections to check for cracks in the fuselage skin and associated components. These checks are particularly focused on the forward galley door area where reports indicated the presence of cracks originating from rough sanding marks. The document comprehensively details the necessary compliance timelines and methods that airlines must follow to adhere to this safety directive.
Significant Issues and Concerns
One significant issue within the document is its use of highly technical language and reference to aviation-specific procedures and terminology. This specificity could make it challenging for individuals without a background in aviation or engineering to fully comprehend the content.
Additionally, the document's reliance on service bulletins and procedural guidance originating from Boeing could be perceived as favoritism. This could raise concerns about the impartiality of the directive, especially since it also specifies that alternative methods of compliance (AMOCs) require approval, in part, from Boeing's authorization body. This centralization of authority might appear to limit transparency and openness in the approval process.
Public Impact
The general public might be affected by this rule indirectly. The proactive safety measures imposed can help enhance the safety of flights, ultimately protecting passengers from potentially catastrophic incidents. Such regulations are crucial as they assure the public of the rigorous safety standards under which aircraft operate. This development might also instill greater confidence in the safety of air travel among passengers.
Stakeholder Impacts
For airlines operating the affected Boeing 737 models, complying with the new directive could lead to increased operational costs and logistical challenges. Conducting inspections and implementing necessary repairs will incur significant expenses and potentially affect flight schedules. Conversely, addressing these safety concerns might prevent more costly incidents down the line.
Manufacturers like Boeing, while shouldering some quality assurance and compliance verification roles, also face increased scrutiny over their manufacturing practices and processes. However, the guidance and involvement of Boeing in the approval of AMOCs might streamline the compliance process for operators, ensuring safety defects are addressed with expertise directly from the manufacturer.
In conclusion, while this document sets crucial safety measures in motion, its technical nature and centralized approval mechanism might raise questions about clarity and impartiality. Nevertheless, the directive reflects the FAA's commitment to maintaining high safety standards in civil aviation.
Issues
• The document contains highly technical language and references specific to aviation safety, which may be difficult for a non-expert to understand.
• There is repeated mention of contacting Boeing for repairs and alternative inspections, which could suggest preferential treatment unless standard practice.
• The document references service bulletins and methods that require industry-specific knowledge to comprehend fully.
• The FAA’s coordination with Boeing and reliance on Boeing-generated documents could potentially appear as favoritism towards a particular company, especially given the complexity and specificity required for compliance.
• Some provisions for alternative methods of compliance (AMOCs) require approval from The Boeing Company Organization Designation Authorization, which may centralize the authority, potentially reducing transparency in the compliance process.
