Abstract
A detachable connection between a pitch control unit arm and a pitch horn of a blade holder in a tail rotor head of a tail rotor of a rotary wing aircraft includes a pin connecting the pitch horn, attached to a blade holder, with the pitch control unit arm of a pitch control unit, by protruding through an arm through hole and at another edge through a pitch horn through hole. By this arrangement, material wear is reduced and maintenance intervals can be reduced. This is reached because the pin is designed as a sliding pin projecting between pitch horn and pitch control unit arm, which is running in the course of its length through a spherical bearing in form of a ball with a central ball through hole.
