Associated Press | The FAA wants new software installed on Boeing 777s to prevent crew from inadvertently engaging the autopilot before takeoff.

The problem can result in a high-speed rejected takeoff and increase the chance of a runway overrun.

Boeing says the problem is rare — just nine reported instances of a rejected takeoff because of inadvertent engagement of the autopilot during the 777’s 15-year service history. There have been no runway overruns associated with the issue.

The airworthiness directive is to be published in the Federal Register on Wednesday. The rule, which applies to certain model 777-200, 777-200LR, 777-300, 777-300ER and 777F series airplanes, takes effect 15 days later.

The 777 is a long-range, wide-body aircraft that seats over 300 passengers.
