This AD was prompted by a determination that the thrust reverser systems on these McDonnell Douglas airplanes do not adequately preclude unwanted deployment of a thrust reverser. We are issuing this AD to prevent an unwanted deployment of a thrust reverser during flight, which could result in reduced controllability of the airplane.
