FAA Requests Boeing 737 Be Examed If Bolts At the Rear Wing Are Not Properly Installed

U.S. Federal Aviation Administration has ordered all Boeing 737 series of aircrafts be immediately examed as the inappropriate installation of bolts at the rear wing may result in the aircrafts losing control. It is reported that the order in force from May 20 is able to involves 6 types 600, 700, 700C, 800, 900, 900ER of Boening737. However, only 1,050 Boening 737 registered in the U.S. are subject to the exam. According to the estimate of FAA, the inspection and maintenance fee per aircraft is close to USD 1,000. It is reported that why FAA made this order was due to a report showing that if the bolts installed on the horizontal stablizer of the rear wing do not have complete anti corrosion coating correctly, it may lead to the incomplete structure of the stablizer, making the aircraft losing control. Boeing declared that it had been a long period before the order was given and was not placed only by the recent case. This will not influence the scheduled timetables for all U.S. airlines.
