The FAA has made a new rule that says if some parts of a plane's landing gear got too hot when fixed, they need to be replaced to keep the plane safe. This is important because it helps prevent the plane from having a rough landing or losing control.
Summary AI
The Federal Aviation Administration (FAA) has issued a final rule for all Boeing 767-200, -300, and -300F airplanes, effective February 12, 2025. This new rule addresses a safety concern where a grinder used during maintenance exceeded its input parameters, possibly causing heat damage to the main landing gear cylinder. The directive requires replacing the affected cylinders to prevent unsafe conditions like landing gear collapse, which could lead to loss of control of the airplane. The rule clarifies that installing a specific Supplemental Type Certificate does not affect compliance with the directive, and it includes provisions for alternative methods of compliance and material incorporations by reference.
Abstract
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 767-200, -300, and -300F airplanes. This AD was prompted by a report of a main landing gear (MLG) collapse event following maintenance where a grinder was operating outside of its input parameters, resulting in possible heat damage to the outer cylinder of the MLG. This AD requires replacing affected outer cylinders. The FAA is issuing this AD to address the unsafe condition on these products.

The recent issuance from the Federal Aviation Administration (FAA) is a significant regulatory measure designed to enhance safety in the aviation sector, specifically concerning Boeing 767-200, -300, and -300F aircraft. This new rule is a response to a reported incident involving the collapse of a plane's main landing gear, which was possibly due to heat damage sustained during maintenance. The regulation mandates the replacement of potentially affected components to mitigate the risk of similar incidents in the future.
General Summary of the Document
The FAA’s rule is a directive known as an airworthiness directive (AD), a critical regulatory tool aimed at maintaining the safety of aircraft. In this particular case, it addresses the possibility of heat-induced damage to the outer cylinder of the main landing gear on certain Boeing models, which was traced back to maintenance procedures. The AD requires all operators of these aircraft to replace any affected main landing gear cylinders. The effective date for compliance is set for February 12, 2025.
Significant Issues and Concerns
There are a few notable concerns associated with this directive. Firstly, the document is technical and detailed, likely presenting challenges for individuals not familiar with aviation regulations to fully grasp its implications. Secondly, the rule lacks a detailed cost analysis for the required replacements; operators might face significant financial burdens without prior knowledge or expectation. Additionally, there is no mention of financial support or assistance for operators, which could be critical given the extensive nature of these repair requirements.
Moreover, the FAA decided not to include a requested parts installation prohibition raised by Boeing, potentially leaving some ambiguity regarding the compliance and movement of aircraft components. Lastly, the directive heavily refers to external materials, like the Boeing Alert Requirements Bulletin, which may not be easily accessible to everyone involved, thus complicating compliance efforts.
Broad Impact on the Public
For the general public, this directive plays a crucial role in maintaining air travel safety standards. Addressing potential safety hazards prevents incidents that could lead to serious injuries or fatalities. While most people won't be directly involved in implementing these changes, the assurance of enhanced safety standards in aircraft they may fly on is an indirect benefit of such regulations.
Impact on Specific Stakeholders
The rule's impact is more immediate and profound for stakeholders such as airline operators and maintenance providers. Airlines owning affected Boeing models will need to plan for and cover the costs of replacing compromised landing gear components. This could translate into operational downtime and financial investments, but it also potentially reduces the risk of costly accidents.
Maintenance crews are directly affected as they are required to update their practices and ensure compliance with the new AD, reinforcing the emphasis on safety. Boeing, as a manufacturer, may experience increased scrutiny over maintenance guidelines and operational safety protocols.
Overall, while the directive places immediate burdens on stakeholders within the industry, it is fundamentally aimed at ensuring the long-term operational safety and reliability of domestic and international flights involving the specified Boeing aircraft models.
Issues
• The document is highly technical and complex, potentially making it difficult for individuals without a background in aviation regulations to fully understand the requirements and implications of the new airworthiness directive.
• There is no detailed cost breakdown for the replacement of affected outer cylinders, making it unclear what the total financial impact on operators might be.
• The document does not mention whether any financial assistance or subsidies are available to operators for compliance with the directive, which could be significant given the scale of replacement parts needed.
• The section explaining the FAA's response to Boeing's request for a parts installation prohibition may be ambiguous, particularly regarding the adequacy of ongoing compliance without such a prohibition, needing further clarification.
• There is a reliance on referenced material (Boeing Alert Requirements Bulletin), which may not be immediately accessible to all parties reading the directive, possibly hindering full understanding or compliance efforts.
