1. An aircraft part comprising:
an access door and
a fuselage part comprising at least one door frame located upstream of the door,
wherein a cavity is formed between, on one side, an upstream edge of the door in a closed position and, on another side, a downstream edge of the fuselage part, which is located facing the upstream edge of the door, upstream and downstream being defined with respect to a direction of airflow outside the aircraft part,
wherein the upstream edge of the door in the closed position is spaced apart from the downstream edge of the fuselage part such that the cavity opens to the outside of the aircraft part via an opening,
wherein the cavity comprises a bottom connected to the upstream edge of the door and to the downstream edge of the fuselage part,
wherein the door is equipped toward the outside with a plate comprising an outer face, and
wherein the outer face of the plate of the door comprises, at the upstream edge of the door that bounds the opening, a chamfer positioned to direct a portion of the airflow outside the aircraft part away from the cavity.
