摘要：

We study the defects of a flap actuator of the wing of an An-124 aircraft. The fractographic and metallographic investigations of the surface defects of a screw–nut friction couple are performed. A device for wear tests under the conditions of fretting corrosion is developed. Recommendations concerning the reduction of possible damage to flap actuators are proposed.
