NATION IN BRIEF : WASHINGTON STATE : Boeing Tells Airlines to Replace 737 Part

Boeing Co. is advising airlines that a mechanism used to make a plane go up or down should be replaced in several models of the Boeing 737 because of reports of malfunction. A Boeing alert service bulletin sent from Seattle to all airlines says that five carriers reported that the horizontal stabilizer, the small wing at the rear of the plane, rotated farther than the pilot commanded. A company spokesman said none of the malfunctions occurred in flight, nor is the problem believed to have contributed to any crash.
