PURPOSE: Structure for preventing the lowering of a landing gear door of an airplane is provided to minimize the air resistance applied to a landing gear door by preventing the instantaneous opening and closing of the landing gear door due to the lowering of the landing gear door and to reduce the consumption of fuel. CONSTITUTION: Structure for preventing lowering of a landing gear door includes the landing gear door installed on a fuselage is opened and closed to go in and out a landing device in landing and taking off. The maximum lowering caused by the negative pressure of the inside of a landing gear bay is generated on other side of other ends of the landing gear door, a maximum preload region which is a first region(R1). Because the lowering is not occurred on the one side of the other end of the landing gear door which is a second region(R2) by supporting a door hinge. In additional, the lowering is also not generated on the both sides of one end of the landing gear door which is a third and fourth region(R3,R4) by an actuator being installed. Therefore, the first region is bent inwardly 1.0 inch more than the second, third, and fourth region.
