PROBLEM TO BE SOLVED: To provide a wing drive device capable of improving flight safety of an aircraft comparing to a conventional one. SOLUTION: The wing drive device 100 is equipped with a flight controller 150 generating a drive signal, servo actuators 120 and 130, a controller 160 having a drive circuit 161, and a controller 170 having a drive circuit 171. The controller 160 has a driven signal generation circuit 162 generating the driven signal allowing the servo actuator 130 to be driven by a steering wing 110 when the drive circuit 161 can make the servo actuator 120 drive the steering wing 110 based on the drive signal. The servo actuator 130 has a solenoid valve 139 disabling the control by the drive circuit 171 based on the driven signal. COPYRIGHT: (C)2004,JPO
