The Federal Aviation Administration (FAA) issued an airworthiness directive (AD) affecting specific General Electric turbofan engines. This directive was prompted by incidents leading to significant fuel loss and engine shutdowns during flights. To address these issues, the AD mandates initial and repetitive shim checks of specific components and performs tests if necessary, to ensure safety. This measure aims to prevent engine failures and potential hazards to aircraft and passengers.
Simple Explanation
Imagine there are special rules to make sure airplane engines don't stop working while flying. These rules say, "Check some parts of the engine to make sure they're okay, and if they're not, fix them so nothing dangerous happens in the sky."
