According to a CNN report on the 6th local time, the FAA ordered hundreds of Boeing 737 MAX series airliners to be inspected for cracks and warned that if damaged and not detected, the structural integrity of the aircraft may be reduced. The FAA said that structural reinforcements around the front service hatch on the right side of the airframe of some airliners were found to be cracked. Airlines must inspect the relevant areas according to the corresponding schedule according to the usage of each aircraft and repair any cracks before the passenger aircraft resumes operation. The new airworthiness directive is expected to cover approximately 471 U.S.-registered Boeing 737 MAX 8, MAX 9, and MAX 8200 aircraft. Boeing said in a statement that the company has carried out engineering analysis to determine the cause of the crack and is studying engineering design improvements to prevent similar problems from occurring again in the future.
