Aircraft structures are very susceptible to impact from foreign objects such as debris, ice crystals from rain or attacks from animals. This incident has a serious impact and poses a threat to the safety of civilian aircraft operations and can lead to disasters such as plane crashes. Currently, Unmanned Aircraft Vehicle (UAV) is developing very rapidly. Horizontal stabilizer is a very important part or component on an airplane. The horizontal stabilizer structure of the aircraft with a passenger of 189 people must be able to withstand the attacks of birds with a mass of 8 lb or about 3600 gr. The purpose of this thesis is to determine the dynamic response of the horizontal stabilizer based on variations in the collision parameters of the drone. This simulation is performed using finite element software or CAE Abaqus. This simulation is carried out by prefixing a drone collision simulation on the horizontal stabilizer section and will be compared to the bird simulation being hit on the horizontal stabilizer section. Drone collision at the location between the ribs in section 2 with an angle of 0o at a relative speed of 151 m/s horizontal stabilizer suffered serious damage. Drone collisions with a smaller mass compared to the horizontal stabilizer are more seriously damaged than bird strikes, because the drones damage the ribs, spars and skins on the horizontal stabilizer.
