Boeing has completed certification testing of the new Messier-Bugatti carbon brakes for the Next Generation 737 family that will be offered on new-build aircraft and as a retrofit programme for in-service aircraft.

A 737-900ER was used for a month-long test programme and is pictured performing a high-speed rejected take-off as part of the trial.

US Federal Aviation Administration certification is expected by the end of June, with production due to start by third quarter.

Boeing says it has achieved its target of demonstrating equivalent performance between steel and carbon brakes, and verified a weight savings of 320kg (700lb) compared with high-capacity steel brakes on 737-700/800/900ERs, and 250kg on standard-capacity steel brakes for 737-600/700s.
