Airworthiness Directives; The Boeing Company Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes. This AD requires an inspection of the number 2 windows to determine whether the link arms are in the over-center position, and modifying the link arms of the number 2 windows in the flight compartment if necessary. This AD also requires the inspection, and modification if necessary, for airplanes that replace a modified assembly with an unmodified assembly. This AD results from reports of the number 2 windows opening during takeoff roll, which has resulted in aborted takeoffs. We are issuing this AD to prevent the opening of the number 2 windows during takeoff roll, which could adversely affect the flightcrew's ability to perform critical takeoff communication and result in an aborted takeoff or an unscheduled landing.
