1. A thrust reverser system for a gas turbine engine comprising:
- a duct including a cowling movable between an open position and a closed position in a direction transverse to a centerline of the gas turbine engine;
a thrust reverser supported within the cowling and movable between an axial closed position, an axial intermediate position and an axial open position; and
a controller commanding movement of the thrust reverser, wherein the controller is actuateable to move the thrust reverser from the axial closed position to the axial intermediate position such that the cowling is free to move to the open position.
