The invention discloses an aircraft empennage regulation mechanism with pitching and yawing completely decoupled. The aircraft empennage regulation mechanism comprises an empennage fixing part, an empennage pitching part and an empennage yawing part, wherein the empennage fixing part, the empennage pitching part and the empennage yawing part are sequentially arranged on the aircraft tail from front to back, the empennage fixing part and the empennage pitching part are hinged, and the empennage pitching part and the empennage yawing part are hinged. The aircraft empennage regulation mechanism further comprises a pitching steering engine and a yawing steering engine, wherein the pitching steering engine and the yawing steering engine are arranged on an aircraft body. The pitching steering engine rotates to drive a connecting rod to move to drive the empennage pitching part to swing around the axis of a pitching rotation shaft. The yawing steering engine rotates to pull two traction ropes to move to drive the empennage yawing part to swing around the axis of a yawing rotation shaft. According to the invention, the structure style of arranging a drive steering engine on the aircraft tail traditionally is abandoned, and the weight of the aircraft tail is effectively lowered. In addition, compared with a traditional kinematic coupling empennage regulation mechanism, the aircraft empennage regulation mechanism can regulate empennages through mechanical decoupling, and the reliability, the stability and the regulation accuracy of a system are greatly improved.
