A first link is pivotally attached at one end to the engine and pivotally attached at its other end to a second link member which in turn is pivotally attached at its other end to the blocker door. A third link member is pivotally attached to the engine rearward of the first link connection and pivotally connected at its other end to the second link intermediate the end of the first link and blocker door. Actuators are provided for linear translation of the rear cowl section.
