The invention belongs to the technical field of airplane fuel oil system design, and particularly relates to a commuting airplane fuel oil ventilation device. The commuter category airplane fuel oil ventilation device is characterized in that in the device, an embedded ventilation opening (1) is positioned in the lower wing surface of an oil tank ventilation separation cabin; the embedded ventilation opening (1) is a bulge provided with a wedge-shaped slope; the top end of the wedge-shaped slope is in the front position of the heading direction; the height of the top end of the wedge-shaped slope surface is aligned with the wing surface; the wide end of the wedge-shaped slope surface is in the back position of the heading direction; through the height of the wide end of the wedge-shaped slope surface, an included angle being 7 to 9 degrees is formed between the slope surface of the wedge-shaped slope surface and the wing surface; the upper surface of the wide end of the wedge-shaped slope surface is provided with a ventilation pipe (8); a flame inhibitor (7) is sealed and fixed on the ventilation pipe (8) of the embedded ventilation opening (1); the cross section of the ventilation pipe (8) is a rectangle with the length-to-width ratio being 4:1 to 3:1; and the length of the cross section of the ventilation pipe (8) is 0.5 to 0.6 of the width of the wide end of the wedge-shaped slope surface.
