FAA Orders All Boeing 737s Inspected <javascript:eMail_Friend(540, 540);> Email this Story Sep 14, 8:00 AM (ET) By LESLIE MILLER WASHINGTON (AP) - The federal government ordered inspections Saturday of Boeing 737s flying worldwide to see if any have potentially defective flight control modules that could make the planes hard to control. The emergency order by the Federal Aviation Administration gives airlines 10 days to complete the review. Each plane has two modules that control hydraulic fluid to the flight control system. A failure of both modules could significantly affect the flight control systems, making the jetliners sluggish to nearly impossible to operate, according to FAA spokesman Paul Takemoto. To check the modules, "you just have to look up into the wheel well and check the serial number," Takemoto said. The FAA said it's looking for a recent batch of modules that has a high rate of failure. Fifteen modules were found to be defective, four while in flight, 11 during inspections on the ground, Takemoto said. None caused an accident, he said. There are 84 foreign aircraft with the modules from the bad batch and nine U.S. 737s, Takemoto said. A spokesman for the company that made the modules, European-based Smiths Aerospace, had no immediate comment on the FAA order. James McKenna, managing editor of Aviation Maintenance magazine, said the airplanes are probably built so that if all of the flight control modules break, the pilot still has some mechanical physical control of the airplane. "Still," he said, "there's a possibility that this could lead to a crash." Seventy-eight of the 93 aircraft with possibly faulty modules have two of the modules on them, Takemoto said.
