The invention discloses a water seepage prevention aircraft safety inspection opening cover. The water seepage prevention aircraft safety inspection opening cover comprises an opening cover body and an opening frame. Opening cover bolts are fixed into threaded holes. A groove is formed in the inner wall of the opening frame and is a T-shaped groove. The groove is perpendicular to the direction of the axis of the opening frame. At least ten elastic buckles which are evenly arranged at intervals are arranged in the groove. The two ends of each elastic buckle are submerged into the groove. The middles of the at least ten elastic buckles penetrate and are connected to a sealing rubber ring. The inner diameter of the sealing rubber ring is smaller than the outer diameter of the opening cover. A boss is arranged on the inner wall of the opening frame in the circumferential direction of the opening frame and is located below the groove. A water collection groove parallel to the axis of the opening frame is formed in the boss. A guide pipe connected with the water collection groove is arranged on one side of the water collection groove. The invention further discloses a manufacturing method of the water seepage prevention aircraft safety inspection opening cover. The problems in the prior art can be solved. The size of a sealing piece in the opening frame can be adjusted in time according to pressure when the opening cover is inserted, and the overall sealing performance is improved.
