The Federal Aviation Administration (FAA) has implemented a new airworthiness directive for Boeing Model 747 airplanes, including a range of series models, due to reports of improper grinding of landing gear outer cylinders. This defective grinding could lead to heat damage, potentially causing structural failure or landing gear collapse, risking loss of control of the aircraft. The directive necessitates replacing any affected parts to ensure safety and prevent the unsafe condition from affecting these airplanes. This rule will take effect on March 17, 2025, and applies to all airplanes of the specified models registered in the United States.
Simple Explanation
The FAA found that some Boeing 747 airplanes have a problem with parts of the landing gear being ground too much, which could make them unsafe. So, they made a rule that says those parts must be replaced to keep the planes safe.
