1. A door installation for an aircraft having retractable landing gear configured to reciprocate between a stowed position and a deployed position, the door installation comprising:
a first door rotatably coupled to the aircraft about a fixed first axis for movement between a raised position and lowered position, the first door including a first uplock that is selectively engaged to maintain the first door in the raised position;
an actuator operably coupled to an inner surface of the first door and configured to selectively drive the first door between the raised position and the lowered position; and
a second door located aft of the first door and coupled to the aircraft for movement between a first position when the landing gear is in the stowed position, and a second position when the landing gear is in the deployed position, the second door including a second uplock that is selectively engaged to maintain the second door in the first position, wherein a portion of the first door overlaps a portion of the second door when the first door is in the raised position and the second door is in the first position so that the first door blocks deployment of the second door to the second position.
