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.
Simple Explanation
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.
