The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for specific Boeing 737 models due to safety concerns from engine fan blade-out (FBO) events. These incidents caused damage to the aircraft, including cracks in the primary exhaust nozzle. The FAA's directive mandates inspections and modifications, such as the installation of bridge brackets or serviceable nozzles, to ensure safety. Operators must also update their maintenance programs to include new airworthiness limitations to prevent future unsafe conditions.
Simple Explanation
The airplane boss says that some airplanes need fixes because a part near the engine got hurt and made other parts fall off, which could be really bad. They told the airplane teams to check and change parts and follow new rules to keep everyone safe when they fly.
