In April 2008, Boeing completed certification testing of new carbon brakes designed for the Next-Generation 737 airplane family by French supplier Messier-Bugatti. A Next-Generation 737-900ER (Extended Range) airplane is shown performing a high-speed rejected takeoff test, designed to verify that an airplane at maximum weight with greatly worn brakes can stop safely after a refused takeoff decision. Boeing will submit the test results to the U.S. Federal Aviation Administration for certification the second quarter this year. Entry into production is expected by third quarter. Boeing will offer a retrofit program for airplanes already in service.
